Clutter Coding Style
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
This document is intended to be a short description of the preferred
|
||||
coding style to be used for the Clutter source code.
|
||||
|
||||
Coding style is a matter of consistency, readability and maintainance;
|
||||
coding style is also completely arbitrary and a matter of taste. This
|
||||
document will use examples at the very least to provide authoritative
|
||||
and consistent answers to common questions regarding the coding style,
|
||||
and will also try to identify the allowed exceptions.
|
||||
|
||||
The examples will show the preferred coding style; the negative examples
|
||||
will be clearly identified. Please, don't submit code to Clutter that
|
||||
looks like any of these.
|
||||
|
||||
Part of the rationales for these coding style rules are available either
|
||||
in the kernel CodingStyle document or in Cairo's CODING_STYLE one.
|
||||
|
||||
When in doubt, check the surrounding code and try to imitate it.
|
||||
|
||||
Clutter provides an Uncrustify configuration file that tries to match
|
||||
this document. Since automated tools are not a substitute for human eye,
|
||||
they should not be entirely relied upon - but they can give an initial
|
||||
layout for contributors.
|
||||
|
||||
+ Line width
|
||||
|
||||
The maximum line width for source files is 80 characters, whenever possible.
|
||||
Longer lines are usually an indication that you either need a function
|
||||
or a pre-processor macro.
|
||||
|
||||
+ Indentation
|
||||
|
||||
Each new level is indented 2 or more spaces than the previous level:
|
||||
|
||||
if (condition)
|
||||
single_statement ();
|
||||
|
||||
This can only be achieved using space characters. It may not be achieved
|
||||
using tab characters alone, or using a combination of spaces and tabs.
|
||||
|
||||
Do not change the editor's configuration to change the meaning of a
|
||||
tab character (see below); code using tabs to indent will not be accepted
|
||||
into Clutter.
|
||||
|
||||
Even if two spaces for each indentation level allows deeper nesting than
|
||||
8 spaces, Clutter favours self-documenting function names that can take
|
||||
quite some space. For this reason you should avoid deeply nested code.
|
||||
|
||||
+ Tab characters
|
||||
|
||||
The tab character must always be expanded to spaces. If a literal
|
||||
tab must be used inside the source, the tab must always be interpreted
|
||||
according to its traditional meaning:
|
||||
|
||||
Advance to the next column which is a multiple of 8.
|
||||
[ these two lines should be aligned ]
|
||||
|
||||
+ Braces
|
||||
|
||||
Curly braces should not be used for single statement blocks:
|
||||
|
||||
if (condition)
|
||||
single_statement ();
|
||||
else
|
||||
another_single_statement (arg1);
|
||||
|
||||
In case of multiple statements, curly braces should be put on another
|
||||
indentation level:
|
||||
|
||||
if (condition)
|
||||
{
|
||||
statement_1 ();
|
||||
statement_2 ();
|
||||
statement_3 ();
|
||||
}
|
||||
|
||||
The "no block for single statements" rule has only three exceptions:
|
||||
|
||||
① if the single statement covers multiple lines, e.g. for functions with
|
||||
many arguments, and it is followed by else or else if:
|
||||
|
||||
/* valid */
|
||||
if (condition)
|
||||
{
|
||||
a_single_statement_with_many_arguments (some_lengthy_argument,
|
||||
another_lengthy_argument,
|
||||
and_another_one,
|
||||
plus_one);
|
||||
}
|
||||
else
|
||||
another_single_statement (arg1, arg2);
|
||||
|
||||
② if the condition is composed of many lines:
|
||||
|
||||
/* valid */
|
||||
if (condition1 ||
|
||||
(condition2 && condition3) ||
|
||||
condition4 ||
|
||||
(condition5 && (condition6 || condition7)))
|
||||
{
|
||||
a_single_statement ();
|
||||
}
|
||||
|
||||
③ Nested if's, in which case the block should be placed on the
|
||||
outermost if:
|
||||
|
||||
/* valid */
|
||||
if (condition)
|
||||
{
|
||||
if (another_condition)
|
||||
single_statement ();
|
||||
else
|
||||
another_single_statement ();
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
if (condition)
|
||||
if (another_condition)
|
||||
single_statement ();
|
||||
else if (yet_another_condition)
|
||||
another_single_statement ();
|
||||
|
||||
In general, new blocks should be placed on a new indentation level,
|
||||
like:
|
||||
|
||||
int retval = 0;
|
||||
|
||||
statement_1 ();
|
||||
statement_2 ();
|
||||
|
||||
{
|
||||
int var1 = 42;
|
||||
gboolean res = FALSE;
|
||||
|
||||
res = statement_3 (var1);
|
||||
|
||||
retval = res ? -1 : 1;
|
||||
}
|
||||
|
||||
While curly braces for function definitions should rest on a new line
|
||||
they should not add an indentation level:
|
||||
|
||||
/* valid */
|
||||
static void
|
||||
my_function (int argument)
|
||||
{
|
||||
do_my_things ();
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
static void
|
||||
my_function (int argument) {
|
||||
do_my_things ();
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
static void
|
||||
my_function (int argument)
|
||||
{
|
||||
do_my_things ();
|
||||
}
|
||||
|
||||
Curly braces must not be placed on the same line as a condition:
|
||||
|
||||
/* invalid */
|
||||
if (condition) {
|
||||
statement_1 ();
|
||||
statement_2 ();
|
||||
}
|
||||
|
||||
+ Conditions
|
||||
|
||||
Do not check boolean values for equality:
|
||||
|
||||
/* invalid */
|
||||
if (condition == TRUE)
|
||||
do_foo ();
|
||||
|
||||
/* valid */
|
||||
if (another_condition)
|
||||
do_bar ();
|
||||
|
||||
Even if C handles NULL equality like a boolean, be explicit:
|
||||
|
||||
/* valid */
|
||||
if (some_pointer == NULL)
|
||||
do_blah ();
|
||||
|
||||
/* invalid */
|
||||
if (some_other_pointer)
|
||||
do_blurp ();
|
||||
|
||||
In case of conditions split over multiple lines, the logical operators should
|
||||
always go at the end of the line:
|
||||
|
||||
/* invalid */
|
||||
if (condition1
|
||||
|| condition2
|
||||
|| condition3)
|
||||
{
|
||||
do_foo ();
|
||||
}
|
||||
|
||||
/* valid */
|
||||
if (condition1 &&
|
||||
condition2 &&
|
||||
(condition3 || (condition4 && condition5)))
|
||||
{
|
||||
do_blah ();
|
||||
}
|
||||
|
||||
+ Functions
|
||||
|
||||
Functions should be declared by placing the returned value on a separate
|
||||
line from the function name:
|
||||
|
||||
void
|
||||
my_function (void)
|
||||
{
|
||||
}
|
||||
|
||||
The arguments list must be broken into a new line for each argument,
|
||||
with the argument names right aligned, taking into account pointers:
|
||||
|
||||
void
|
||||
my_function (some_type_t type,
|
||||
another_type_t *a_pointer,
|
||||
final_type_t another_type)
|
||||
{
|
||||
}
|
||||
|
||||
The alignment also holds when invoking a function without breaking the
|
||||
80 characters limit:
|
||||
|
||||
align_function_arguments (first_argument,
|
||||
second_argument,
|
||||
third_argument);
|
||||
|
||||
To respect the 80 characters limit do not break the function name from
|
||||
the arguments:
|
||||
|
||||
/* invalid */
|
||||
a_very_long_function_name_with_long_parameters
|
||||
(argument_the_first, argument_the_second);
|
||||
|
||||
/* valid */
|
||||
first_a = argument_the_first;
|
||||
second_a = argument_the_second;
|
||||
a_very_long_function_name_with_long_parameters (first_a, second_a);
|
||||
|
||||
+ Whitespace
|
||||
|
||||
Always put a space before a parenthesis but never after:
|
||||
|
||||
/* valid */
|
||||
if (condition)
|
||||
do_my_things ();
|
||||
|
||||
/* valid */
|
||||
switch (condition)
|
||||
{
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
if(condition)
|
||||
do_my_things();
|
||||
|
||||
/* invalid */
|
||||
if ( condition )
|
||||
do_my_things ( );
|
||||
|
||||
A switch() should open a block on a new indentation level, and each case
|
||||
should start on the same indentation level as the curly braces, with the
|
||||
case block on a new indentation level:
|
||||
|
||||
/* valid */
|
||||
switch (condition)
|
||||
{
|
||||
case FOO:
|
||||
do_foo ();
|
||||
break;
|
||||
|
||||
case BAR:
|
||||
do_bar ();
|
||||
break;
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
switch (condition) {
|
||||
case FOO: do_foo (); break;
|
||||
case BAR: do_bar (); break;
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
switch (condition)
|
||||
{
|
||||
case FOO: do_foo ();
|
||||
break;
|
||||
case BAR: do_bar ();
|
||||
break;
|
||||
}
|
||||
|
||||
/* invalid */
|
||||
switch (condition)
|
||||
{
|
||||
case FOO:
|
||||
do_foo ();
|
||||
break;
|
||||
case BAR:
|
||||
do_bar ();
|
||||
break;
|
||||
}
|
||||
|
||||
It is preferable, though not mandatory, to separate the various cases with
|
||||
a newline:
|
||||
|
||||
switch (condition)
|
||||
{
|
||||
case FOO:
|
||||
do_foo ();
|
||||
break;
|
||||
|
||||
case BAR:
|
||||
do_bar ();
|
||||
break;
|
||||
|
||||
default:
|
||||
do_default ();
|
||||
}
|
||||
|
||||
The 'break' statement for the default: case is not mandatory.
|
||||
|
||||
If a case block needs to declare new variables, the same rules as the
|
||||
inner blocks (see above) apply; the break statement should be placed
|
||||
outside of the inner block:
|
||||
|
||||
switch (condition)
|
||||
{
|
||||
case FOO:
|
||||
{
|
||||
int foo;
|
||||
|
||||
foo = do_foo ();
|
||||
}
|
||||
break;
|
||||
|
||||
...
|
||||
}
|
||||
|
||||
When declaring a structure type use newlines to separate logical sections
|
||||
of the structure:
|
||||
|
||||
struct _ClutterActorPrivate
|
||||
{
|
||||
/* fixed position */
|
||||
ClutterUnit fixed_x;
|
||||
ClutterUnit fixed_y;
|
||||
|
||||
ClutterRequestMode request_mode;
|
||||
|
||||
/* requisition sizes */
|
||||
ClutterUnit request_width_for_height;
|
||||
ClutterUnit request_min_width;
|
||||
ClutterUnit request_natural_width;
|
||||
ClutterUnit request_height_for_width;
|
||||
ClutterUnit request_min_height;
|
||||
ClutterUnit request_natural_height;
|
||||
|
||||
ClutterActorBox allocation;
|
||||
|
||||
...
|
||||
};
|
||||
|
||||
Do not eliminate whitespace and newlines just because something would
|
||||
fit on 80 characters:
|
||||
|
||||
/* invalid */
|
||||
if (condition) foo (); else bar ();
|
||||
|
||||
Do eliminate trailing whitespace on any line, preferably as a separate
|
||||
patch or commit. Never use empty lines at the beginning or at the end of
|
||||
a file.
|
||||
|
||||
Do enable the default git pre-commit hook that detect trailing
|
||||
whitespace for you and help you to avoid corrupting Clutter's tree with
|
||||
it. Do that as follows:
|
||||
|
||||
chmod a+x .git/hooks/pre-commit
|
||||
|
||||
You might also find the git-stripspace utility helpful which acts as a
|
||||
filter to remove trailing whitespace as well as initial, final, and
|
||||
duplicate blank lines.
|
||||
|
||||
+ Headers
|
||||
|
||||
Headers are special, for Clutter, in that they don't have to obey the
|
||||
80 characters limit. The only major rule for headers is that the functions
|
||||
definition should be vertically aligned in three columns:
|
||||
|
||||
return value function_name (type argument,
|
||||
type argument,
|
||||
type argument);
|
||||
|
||||
The maximum width of each column is given by the longest element in the
|
||||
column:
|
||||
|
||||
void clutter_type_set_property (ClutterType *type,
|
||||
const gchar *value,
|
||||
GError **error);
|
||||
const gchar *clutter_type_get_property (ClutterType *type);
|
||||
|
||||
It is also possible to align the columns to the next tab:
|
||||
|
||||
void clutter_type_set_prop (ClutterType *type,
|
||||
gfloat value);
|
||||
gfloat clutter_type_get_prop (ClutterType *type);
|
||||
gint clutter_type_update_foobar (ClutterType *type);
|
||||
|
||||
Public headers should never be included directly:
|
||||
|
||||
#if !defined(__CLUTTER_H_INSIDE__) && !defined(CLUTTER_COMPILATION)
|
||||
#error "Only <clutter/clutter.h> can be included directly."
|
||||
#endif
|
||||
|
||||
Public headers should also have inclusion guards (for internal usage)
|
||||
and C++ guards:
|
||||
|
||||
#ifndef __CLUTTER_HEADER_H__
|
||||
#define __CLUTTER_HEADER_H__
|
||||
|
||||
#include <clutter/clutter-actor.h>
|
||||
|
||||
G_BEGIN_DECLS
|
||||
|
||||
...
|
||||
|
||||
G_END_DECLS
|
||||
|
||||
#endif /* __CLUTTER_HEADER_H__ */
|
||||
|
||||
+ Includes
|
||||
|
||||
Clutter source files should never include the global clutter.h header, but
|
||||
instead include the individual headers that are needed. Every file must
|
||||
include config.h first, then its own header, then other Clutter headers
|
||||
that it needs, then system and third-party headers that it needs.
|
||||
|
||||
/* valid */
|
||||
#include "config.h"
|
||||
|
||||
#include "clutter-foo.h"
|
||||
|
||||
#include "clutter-actor.h"
|
||||
#include "clutter-container.h"
|
||||
|
||||
...
|
||||
|
||||
#include <string.h>
|
||||
|
||||
+ GObject
|
||||
|
||||
GObject classes definition and implementation require some additional
|
||||
coding style notices.
|
||||
|
||||
Typedef declarations should be placed at the beginning of the file:
|
||||
|
||||
typedef struct _ClutterActor ClutterActor;
|
||||
typedef struct _ClutterActorPrivate ClutterActorPrivate;
|
||||
typedef struct _ClutterActorClass ClutterActorClass;
|
||||
|
||||
This includes enumeration types:
|
||||
|
||||
typedef enum {
|
||||
CLUTTER_REQUEST_WIDTH_FOR_HEIGHT,
|
||||
CLUTTER_REQUEST_HEIGHT_FOR_WIDTH
|
||||
} ClutterRequestMode;
|
||||
|
||||
And callback types:
|
||||
|
||||
typedef void (* ClutterCallback) (ClutterActor *actor,
|
||||
gpointer user_data);
|
||||
|
||||
Instance structures should only contain the parent type and a pointer to a
|
||||
private data structure, and they should be annotated as "private":
|
||||
|
||||
struct _ClutterRectangle
|
||||
{
|
||||
/*< private >*/
|
||||
ClutterActor parent_instance;
|
||||
|
||||
ClutterRectanglePrivate *priv;
|
||||
};
|
||||
|
||||
All the properties should be stored inside the private data structure, which
|
||||
is defined inside the source file - or, if needed, inside a private header
|
||||
file; the private header filename must end with "-private.h" and must not be
|
||||
installed.
|
||||
|
||||
The private data structure should only be accessed internally using the
|
||||
pointer inside the instance structure, and never using the
|
||||
G_TYPE_INSTANCE_GET_PRIVATE() macro or the g_type_instance_get_private()
|
||||
function.
|
||||
|
||||
Always use the G_DEFINE_TYPE(), G_DEFINE_TYPE_WITH_CODE() macros, or
|
||||
their abstract variants G_DEFINE_ABSTRACT_TYPE() and
|
||||
G_DEFINE_ABSTRACT_TYPE_WITH_CODE().
|
||||
|
||||
Avoid forward declaration for functions: use the G_DEFINE_* macros right
|
||||
after the private types, variables and macros declarations.
|
||||
|
||||
Interface types should always have the dummy typedef for cast purposes:
|
||||
|
||||
typedef struct _ClutterFoo ClutterFoo;
|
||||
|
||||
The interface structure should have "Iface" postfixed to the dummy typedef:
|
||||
|
||||
typedef struct _ClutterFooIface ClutterFooIface;
|
||||
|
||||
Interfaces must have the following macros:
|
||||
|
||||
- Macro: - Expands to:
|
||||
• CLUTTER_TYPE_<iface_name> <iface_name>_get_type
|
||||
• CLUTTER_<iface_name> G_TYPE_CHECK_INSTANCE_CAST
|
||||
• CLUTTER_IS_<iface_name> G_TYPE_CHECK_INSTANCE_TYPE
|
||||
• CLUTTER_<iface_name>_GET_IFACE G_TYPE_INSTANCE_GET_INTERFACE
|
||||
|
||||
+ Memory allocation
|
||||
|
||||
When dynamically allocating data on the heap either use g_new() or,
|
||||
if allocating multiple small data structures, g_slice_new().
|
||||
|
||||
Public structure types should always be returned after being zero-ed,
|
||||
either explicitly for each member, or by using g_new0() or g_slice_new0().
|
||||
|
||||
+ Macros
|
||||
|
||||
Try to avoid private macros unless strictly necessary. Remember to #undef
|
||||
them at the end of a block or a series of functions needing them.
|
||||
|
||||
Inline functions are usually preferable to private macros.
|
||||
|
||||
Public macros should not be used unless they evaluate to a constant.
|
||||
|
||||
+ Public API
|
||||
|
||||
Avoid exporting variables as public API, since this is cumbersome on some
|
||||
platforms. It is always preferable to add getters and setters instead.
|
||||
|
||||
+ Private API
|
||||
|
||||
Non-exported functions that are needed in more than one source file
|
||||
should be named "_clutter_...", and declared in a private header file.
|
||||
|
||||
Underscore-prefixed functions are never exported.
|
||||
|
||||
Non-exported functions that are only needed in one source file
|
||||
should be declared static.
|
||||
|
||||
+ Documentation
|
||||
|
||||
All public APIs must have gtk-doc comments. For functions, these should
|
||||
be placed in the source file, directly above the function.
|
||||
|
||||
/* valid */
|
||||
/**
|
||||
* clutter_get_flow:
|
||||
* @actor: a #ClutterActor
|
||||
*
|
||||
* Gets the flow of an actor.
|
||||
*
|
||||
* Note that flows may be laminar or turbulent...
|
||||
*
|
||||
* Return value: (transfer none): the flow of @actor
|
||||
*/
|
||||
ClutterFlow *
|
||||
clutter_get_flow (ClutterActor *actor)
|
||||
{
|
||||
...
|
||||
}
|
||||
|
||||
Doc comments for macros, function types, class structs, etc should be
|
||||
placed next to the definitions, typically in headers.
|
||||
|
||||
Section introductions should be placed in the source file they describe,
|
||||
after the license header:
|
||||
|
||||
/* valid */
|
||||
/**
|
||||
* SECTION:clutter-align-constraint
|
||||
* @Title: ClutterAlignConstraint
|
||||
* @Short_Description: A constraint aligning the position of an actor
|
||||
*
|
||||
* #ClutterAlignConstraint is a #ClutterConstraint that aligns the position
|
||||
* of the #ClutterActor to which it is applied to the size of another
|
||||
* #ClutterActor using an alignment factor
|
||||
*
|
||||
* [...]
|
||||
*/
|
||||
|
||||
To properly document a new function, macro, function type or struct,
|
||||
it needs to be listed in the clutter-sections.txt file.
|
||||
|
||||
To properly document a new class, it needs to be given its own section
|
||||
in clutter-sections.txt, needs to be included in clutter-docs.xml, and the
|
||||
get_type function needs to listed in clutter.types.
|
||||
|
||||
+ Old code
|
||||
|
||||
It is ok to update the style of a code block or function when you
|
||||
are touching it anyway, but sweeping whitespace changes obscure the
|
||||
git history and should be avoided.

GENERAL
|
||||
=======
|
||||
|
||||
General notes and rules on clutter core hacking;
|
||||
|
||||
- Follow the CODING_STYLE document.
|
||||
|
||||
- *Really* follow the CODING_STYLE document.
|
||||
|
||||
- All non static public API funcs should be documented in the source files
|
||||
via gtk-doc. Structures, enumerations and macros should be documented in
|
||||
the header files.
|
||||
|
||||
- All non-trivial static and private API should be documented, especially
|
||||
the eventual lifetime handling of the arguments/return values or locking
|
||||
of mutexes.
|
||||
|
||||
- Properties should always be in floating point (never fixed point).
|
||||
The preferred precision is double for angles, and single precision
|
||||
for size and position -- especially if they have to be passed down
|
||||
to Cogl.
|
||||
|
||||
- Properties should use pixels whenever is possible. Dimensional and
|
||||
positional properties can also use ClutterParamSpecUnits to define
|
||||
the units-based logical values with a unit type.
|
||||
|
||||
- The nick and blurb of properties in public classes should be marked for
|
||||
translation by using the P_() macro defined in the clutter-private.h
|
||||
header file.
|
||||
|
||||
- Public entry points must always check their arguments with
|
||||
g_return_if_fail() or g_return_val_if_fail().
|
||||
|
||||
- Private entry points should use g_assert() or g_warn_if_fail() to
|
||||
verify internal state; do not use g_return_if_fail() or
|
||||
g_return_val_if_fail() as they might be compiled out.
|
||||
|
||||
- If you need to share some state variable across source files use
|
||||
ClutterContext and a private accessor.
|
||||
|
||||
- Private, non-static functions must begin with an underscore and
|
||||
be declared inside clutter-private.h.
|
||||
|
||||
- Don't add direct GL calls but add API to Cogl (both GL and GL|ES
|
||||
versions if possible).
|
||||
|
||||
- Use the CLUTTER_NOTE() macro for debug statements in Clutter, and
|
||||
the COGL_NOTE() macro for debug statements in Cogl. If necessary,
|
||||
add a value inside ClutterDebugFlags or CoglDebugFlags to specify
|
||||
the debug section.
|
||||
|
||||
- New features should also include an exhaustive test unit under
|
||||
tests/conform and, eventually, a user-interactive test under
|
||||
tests/interactive.
|
||||
|
||||
- When committing, use the standard git commit message format:
|
||||
|
||||
=== begin example commit ===
|
||||
Short explanation of the commit
|
||||
|
||||
Longer explanation explaining exactly what's changed, whether any
|
||||
external or private interfaces changed, what bugs were fixed (with bug
|
||||
tracker reference if applicable) and so forth. Be concise but not too
|
||||
brief. Don't be afraid of using UTF-8, or even ASCII art.
|
||||
=== end example commit ===
|
||||
|
||||
- Always add a brief description of the commit to the _first_ line of
|
||||
the commit and terminate by two newlines (it will work without the
|
||||
second newline, but that is not nice for the interfaces).
|
||||
|
||||
short description - MUST be less than 72 characters
|
||||
<newline> - MANDATORY empty line
|
||||
long description - Each line MUST be less than 76 characters
|
||||
|
||||
- Do NOT put the commit message on the short description line. One line
|
||||
commit messages should be avoided, unless they can be *fully* explained
|
||||
in less than 72 characters (e.g. "Fix typo in
|
||||
clutter_actor_create_pango_context() docs").
|
||||
|
||||
- The brief description might optionally have a "tag", i.e. a word or two
|
||||
followed by a color, detailing what part of the repository the commit
|
||||
affected, e.g.:
|
||||
|
||||
alpha: Add :mode property
|
||||
text: Emit ::cursor-event only on changes
|
||||
|
||||
- The tag counts as part of overall character count, so try using
|
||||
a short word. Optionally, you can also use the "[tag]" form.
|
||||
|
||||
- Build environment fixes should use the "build" tag.
|
||||
|
||||
- Think of the commit message as an email sent to the maintainers explaining
|
||||
"what" you did and, more importantly, "why" you did it. The "how" is not
|
||||
important, since "git show" will show the patch inlined with the commit
|
||||
message.

IMPLEMENTING BACKENDS
|
||||
===============================================================================
|
||||
|
||||
Clutter supports multiple backends for handling windowing systems and
|
||||
GL/GLES API on different platforms.
|
||||
|
||||
The GL and GLES API are abstracted by the COGL library. The windowing
|
||||
system is handled by the ClutterBackend implementations inside Clutter
|
||||
itself.
|
||||
|
||||
Clutter, at the moment, supports only in-tree backends.
|
||||
|
||||
In order to write a new backend for a specific platform you should
|
||||
create a new sub-directory under clutter/clutter containing:
|
||||
|
||||
<backend>/clutter-backend-<backend>.h
|
||||
<backend>/clutter-backend-<backend>.c
|
||||
|
||||
-- The subclass of the ClutterBackend abstract class.
|
||||
|
||||
<backend>/clutter-stage-<backend>.h
|
||||
<backend>/clutter-stage-<backend>.c
|
||||
|
||||
-- The implementation of the stage window
|
||||
|
||||
<backend>/clutter-device-manager-<backend>.h
|
||||
<backend>/clutter-device-manager-<backend>.c
|
||||
|
||||
-- The implementation of the input device manager
|
||||
|
||||
<backend>/clutter-event-<backend>.c
|
||||
|
||||
-- Event-specific code (optional)
|
||||
|
||||
<backend>/clutter-<backend>.h
|
||||
|
||||
-- A header for the backend-specific API that should be installed
|
||||
by Clutter inside the include directory along with the rest of
|
||||
the public API headers (optional).
|
||||
|
||||
|
||||
Implementing ClutterBackend
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
Each backend must implement the
|
||||
|
||||
GType
|
||||
_clutter_backend_impl_get_type (void);
|
||||
|
||||
function declared inside clutter/clutter-private.h. The implementation
|
||||
of the function must return the same GType of the backend implementation,
|
||||
for instance:
|
||||
|
||||
GType
|
||||
_clutter_backend_impl_get_type (void)
|
||||
{
|
||||
return CLUTTER_TYPE_BACKEND_GLX;
|
||||
}
|
||||
|
||||
The ClutterBackend implementation is a singleton instance, and the
|
||||
backend must ensure that every time g_object_new() is called the same
|
||||
pointer is returned (with its reference count increased). The GObject
|
||||
API reference describes how to use the ::constructor virtual function
|
||||
to implement a singleton, so you should refer to that.
|
||||
|
||||
The ClutterBackend implementation should hold a single drawing context
|
||||
for its entire lifetime; stage implementations should be "made current"
|
||||
when needed.
|
||||
|
||||
When implementing the ClutterBackend subclass these virtual functions
|
||||
can be overridden:
|
||||
|
||||
ClutterBackend::add_options
|
||||
-- Use this function to install new, backend-specific GOptionEntry
|
||||
definitions to the Clutter GOptionGroup. This function is guaranteed
|
||||
to be called just once.
|
||||
|
||||
ClutterBackend::pre_parse
|
||||
-- Use this function to check for environment variables or setting
|
||||
up default values before the command line arguments are parsed.
|
||||
This function is guaranteed to be called just once.
|
||||
|
||||
ClutterBackend::post_parse
|
||||
-- Use this function to prepare the backend with the values either
|
||||
set inside the ::pre_parse virtual function or by the command
|
||||
line options parsing code. This function is guaranteed to be
|
||||
called just once.
|
||||
|
||||
ClutterBackend::init_events
|
||||
-- Use this function to initialize the event handling. This function
|
||||
is guaranteed to be called just once.
|
||||
|
||||
ClutterBackend::get_features
|
||||
-- Use this function to retrieve the features detectable at runtime
|
||||
from the GL or GLES implementation, plus the eventual backend-specific
|
||||
features.
|
||||
|
||||
ClutterBackend::create_context
|
||||
-- This function is used to create the drawing context to be used
|
||||
by Clutter. Clutter will call this function during the initialization
|
||||
phase. A GL (or GLES) context must always be available after the
|
||||
initialization, so that Cogl and Clutter can query it for capabilities.
|
||||
This function might be called multiple times so if a context was
|
||||
successfully created in a previous call, this function should
|
||||
short-circuit early and return TRUE
|
||||
|
||||
ClutterBackend::ensure_context
|
||||
-- This function is used to ensure that the backend drawing context
|
||||
is made current for passed ClutterStage, using the backend-specific
|
||||
API. This function is called each time a new stage is going to
|
||||
be painted. If the Stage is inside its destruction sequence this
|
||||
function should either fall back the drawing context to a default
|
||||
drawing surface or should unset the drawing surface from the
|
||||
drawing context.
|
||||
|
||||
ClutterBackend::create_stage
|
||||
-- This function is used to create the stage implementation. It will
|
||||
receive as an argument the ClutterStage instance that is "wrapping"
|
||||
the actual implementation being created. The backend must create
|
||||
its stage implementation, initialise it and then return it; in case
|
||||
of error, the backend must return NULL and set the passed GError.
|
||||
|
||||
ClutterBackend::get_device_manager
|
||||
-- This function is used to return the ClutterDeviceManager instance
|
||||
that is going to be returned by clutter_device_manager_get_default()
|
||||
and that should be used internally by input event translation.
|
||||
|
||||
Implementing the stage
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
ClutterStage acts as a wrapper object relaying all the drawing operations
|
||||
to the actual implementation. The implementation of the stage can be any
|
||||
GObject subclass, as long as it implements the ClutterStageWindow interface.
|
||||
|
||||
The ClutterStageWindow interface contains a set of virtual functions that
|
||||
should be overridden by backends that support a windowing system, like
|
||||
::set_title(), ::set_fullscreen(), ::set_cursor_visible(), etc.
|
||||
|
||||
The stage implementation actor must implement:
|
||||
|
||||
• ClutterStageWindow::get_wrapper()
|
||||
• ClutterStageWindow::realize() and ::unrealize()
|
||||
• ClutterStageWindow::show() and ::hide()
|
||||
• ClutterStageWindow::resize()
|
||||
• ClutterStageWindow::get_geometry()
|
||||
• ClutterStageWindow::redraw()
|
||||
|
||||
The ::get_wrapper() implementation should return the pointer to the
|
||||
ClutterStage actor using the ClutterStageWindow implementation.
|
||||
|
||||
In the ::realize virtual function the stage implementation should:
|
||||
|
||||
- create a new native window handle
|
||||
- ensure that there is a GL (or GLES) context
|
||||
- make sure that the native window handle is compatible with
|
||||
the GL (or GLES) context
|
||||
|
||||
The return value should be TRUE if the stage implementation was successfully
|
||||
realized, and FALSE otherwise.
|
||||
|
||||
Inside the ::unrealize function the stage implementation should destroy
|
||||
the native window handle created in ::realize().
|
||||
|
||||
The ::resize() virtual function implementation should cause an update
|
||||
of the COGL viewport.
|
||||
|
||||
The ::redraw() virtual function implementation should contain the platform
|
||||
specific drawing logic, and call _clutter_stage_do_paint() on the ClutterStage
|
||||
wrapper instance to cause the scene to be painted.
|
||||
|
||||
The stage implementation actor can optionally implement:
|
||||
|
||||
• ClutterStageWindow::get_pending_swaps()
|
||||
|
||||
The get_pending_swaps() implementation should return the number of swap
|
||||
buffer requests pending completion. This is only relevent for backends
|
||||
that also support CLUTTER_FEATURE_SWAP_EVENTS.
|
||||
|
||||
If the stage window is supposed to handle events, then it should also implement
|
||||
the ClutterEventTranslator interface; this interface has a single virtual
|
||||
function:
|
||||
|
||||
• ClutterEventTranslator::translate_event()
|
||||
|
||||
which gets passed a pointer to the native event data structure, and a pointer
|
||||
to a newly-allocated, empty ClutterEvent. The EventTranslator implementation
|
||||
should then decide between three options:
|
||||
|
||||
- translate the native event and return CLUTTER_TRANSLATE_QUEUE to
|
||||
let Clutter queue it up in the events queue;
|
||||
- return CLUTTER_TRANSLATE_CONTINUE to let other event translators handle
|

the event;

- return CLUTTER_TRANSLATE_REMOVE to ignore the event.

|
||||
Implementing ClutterDeviceManager
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
Backends with input devices should provide a ClutterDeviceManager
|
||||
implementation to handle addition, removal and input device event translation
|
||||
through the ClutterEventTranslator interface.
|
||||
|
||||
NOTES
|
||||
===============================================================================
|
||||
|
||||
• If the platform is using X11 you should probably subclass ClutterBackendX11
|
||||
and ClutterStageX11, which will provide you with a ready to use code
|
||||
implementation for event handling and window management.

RELEASING
|
||||
=========
|
||||
|
||||
When making a new release;
|
||||
|
||||
- Verify that you don't have uncommitted and unpublished
|
||||
changes, i.e. both this:
|
||||
|
||||
$ git status
|
||||
|
||||
and this:
|
||||
|
||||
$ git diff --stat master origin/master
|
||||
|
||||
should be empty. Commit and push before the next step.
|
||||
|
||||
- Clean your work directory:
|
||||
|
||||
$ git clean -xdf
|
||||
|
||||
This ensures that you don't have stale files lying around.
|
||||
|
||||
- Run:
|
||||
|
||||
$ ./autogen.sh --enable-gtk-doc --enable-docs
|
||||
$ make all
|
||||
$ make check
|
||||
|
||||
And verify that the code builds from a clean Git snapshot.
|
||||
|
||||
- Update the release documentation:
|
||||
|
||||
- NEWS: new feature details, bugs fixed, acknowledgements
|
||||
- README: dependencies, any behavioural changes relevant to
|
||||
developers;
|
||||
|
||||
then commit the changes.
|
||||
|
||||
- Bump clutter_micro_version to the next even number; if this is a stable
|
||||
release, bump up clutter_interface_version by one as well. Then commit
|
||||
the changes.
|
||||
|
||||
- Run:
|
||||
|
||||
$ make release-publish
|
||||
|
||||
which will:
|
||||
|
||||
- do sanity checks on the build
|
||||
- distcheck the release
|
||||
- tag the repository with the version number
|
||||
- upload the tarball to the remote server (needs SSH account)
|
||||
|
||||
- Bump clutter_micro_version to the next odd number; if this is a stable
|
||||
release, bump up clutter_interface_version by one as well. Then commit
|
||||
the changes.
|
||||
|
||||
- Push the branch and then the tag, e.g.:
|
||||
|
||||
$ git push origin master
|
||||
$ git push origin 1.2.4
|
||||
|
||||
- Announce release to the waiting world on the blog and mailing lists. Use
|
||||
the template printed by `make release-publish`.

ClutterActor Invariants
|
||||
===============================================================================
|
||||
|
||||
ClutterActor behaviour has invariants that will be kept with the same API and
|
||||
ABI guarantees as the whole Clutter library.
|
||||
|
||||
This document refers to the 0.8 release of Clutter.

i. Flags
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
This section describes the various flags and enumerations used by
|
||||
ClutterActor.
|
||||
|
||||
a. Public ClutterActor Flags
|
||||
|
||||
CLUTTER_ACTOR_REALIZED
|
||||
Means: the actor has GPU resources associated to its paint
|
||||
cycle. Note however that an actor is allowed to allocate Cogl
|
||||
resources before being realized because Clutter only ever uses
|
||||
one rendering context which is always current. An actor is
|
||||
free to create resources at any time.
|
||||
|
||||
Set by clutter_actor_realize(), unset by
|
||||
clutter_actor_unrealize(). Generally set implicitly when the
|
||||
actor becomes MAPPED (see below).
|
||||
|
||||
May only be set if one of the actor's ancestors is a toplevel.
|
||||
May only be set if all of the actor's ancestors are realized.
|
||||
|
||||
Once realized an actor remains realized until removed from the
|
||||
toplevel. Hide, reparent will not unrealize; but unparent or
|
||||
destroy will unrealize since they remove the actor from the
|
||||
toplevel.
|
||||
|
||||
CLUTTER_ACTOR_MAPPED
|
||||
Means: the actor will be painted if the stage is mapped.
|
||||
|
||||
On non-toplevels, will be set if all of the following are
|
||||
true, and unset otherwise:
|
||||
* the actor's VISIBLE flag is set
|
||||
* all of the actor's non-toplevel ancestors have the MAPPED
|
||||
flag set
|
||||
* the actor has a toplevel ancestor
|
||||
* the toplevel ancestor's VISIBLE flag is set
|
||||
* the toplevel ancestor's REALIZED flag is set
|
||||
|
||||
On toplevels, MAPPED is set asynchronously when the window
|
||||
system notifies Clutter that the toplevel has been made
|
||||
visible on the screen.
|
||||
|
||||
The MAPPED flag requires that an actor is REALIZED. When
|
||||
Clutter sets the MAPPED flag, it forces realization; this is
|
||||
the "normal" way for realization to occur, though explicit
|
||||
realization with clutter_actor_realize() is permitted.
|
||||
|
||||
Reparent may not change the MAPPED flag if the old and the
|
||||
new parent are both MAPPED.
|
||||
|
||||
CLUTTER_ACTOR_VISIBLE
|
||||
Means: the actor's "visible" property was set to true by
|
||||
the application programmer.
|
||||
|
||||
Set by clutter_actor_show(), unset by clutter_actor_hide().
|
||||
|
||||
This is an application-controlled property, while MAPPED and
|
||||
REALIZED are usually managed by Clutter (with the exception
|
||||
that applications can "realize early" with
|
||||
clutter_actor_realize()).
|
||||
|
||||
If VISIBLE is unset, the actor (and any children) must
|
||||
be immediately unmapped, to maintain the invariants for
|
||||
the MAPPED flag.
|
||||
|
||||
CLUTTER_ACTOR_REACTIVE
|
||||
Set and unset by clutter_actor_set_reactive()
|
||||
Means: the actor is now reactive to events.
|
||||
Notes:
|
||||
* If parents need to be reactive for child its up to the
|
||||
parent implementation. In the case of ClutterGroup it
|
||||
being marked unreactive does not mark all children unreactive.
|
||||
* Clutter stage is always reactive.
|
||||
|
||||
|
||||
b. Private ClutterActor flags
|
||||
|
||||
CLUTTER_ACTOR_IN_DESTRUCTION
|
||||
Set internally by clutter_actor_destroy().
|
||||
Used to avoid uneeded overhead when freeing GPU resources on unrealize
|
||||
|
||||
CLUTTER_ACTOR_IS_TOPLEVEL
|
||||
Set internally by the initialization of ClutterStage
|
||||
|
||||
CLUTTER_ACTOR_IN_REPARENT [DEPRECATED]
|
||||
Set internally by clutter_actor_reparent(). This flag
|
||||
optimizes the reparent process by avoiding the need
|
||||
to pass through an unrealized state when the actor is
|
||||
removed from the old parent.
|
||||
|
||||
CLUTTER_ACTOR_IN_PAINT:
|
||||
Set internally by clutter_actor_paint()
|
||||
|
||||
CLUTTER_ACTOR_IN_RELAYOUT
|
||||
Set internally by clutter_actor_allocate()
|
||||
|
||||
c. Pick Modes
|
||||
|
||||
CLUTTER_PICK_NONE
|
||||
No pick operation is performed during the paint
|
||||
|
||||
CLUTTER_PICK_REACTIVE
|
||||
Only reactive actors will be picked
|
||||
|
||||
CLUTTER_PICK_ALL
|
||||
All visible actors will be picked
|
||||
|
||||
ii. Invariants
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
This section describes the various constraints and invariants on ClutterActor.
|
||||
|
||||
In the following
|
||||
|
||||
A => B means if A is true then B is true
|
||||
A <=> B means A is true if and only if B is true
|
||||
(equivalent to A => B && A <= B)
|
||||
|
||||
1) CLUTTER_ACTOR_IN_DESTRUCTION => !CLUTTER_ACTOR_IS_MAPPED (actor) &&
|
||||
!CLUTTER_ACTOR_IS_REALIZED (actor)
|
||||
|
||||
clutter_actor_destroy() will cause an actor to be unparented,
|
||||
which means the actor must be unmapped and unrealized as
|
||||
well.
|
||||
|
||||
2) CLUTTER_ACTOR_IS_MAPPED (actor) => CLUTTER_ACTOR_IS_REALIZED (actor)
|
||||
|
||||
when an actor is mapped, it must first be realized.
|
||||
|
||||
This is the most common way an actor becomes realized.
|
||||
|
||||
3) if clutter_actor_add_child (parent, actor):
|
||||
((parent_is_not_toplevel && CLUTTER_ACTOR_IS_MAPPED (parent)) ||
|
||||
(parent_is_toplevel && CLUTTER_ACTOR_IS_VISIBLE(parent))) &&
|
||||
CLUTTER_ACTOR_IS_VISIBLE (actor)
|
||||
=> CLUTTER_ACTOR_IS_MAPPED (actor)
|
||||
|
||||
calling clutter_actor_add_child() on an actor and a mapped
|
||||
parent will map the actor if it has been shown.
|
||||
|
||||
4) if clutter_actor_remove_child (parent, actor):
|
||||
CLUTTER_ACTOR_IS_MAPPED (actor) <=> CLUTTER_ACTOR_IN_REPARENT
|
||||
|
||||
calling clutter_actor_remove_child() on an actor will unmap and
|
||||
unrealize the actor since it no longer has a toplevel.
|
||||
|
||||
calling clutter_actor_reparent() on an actor will leave the
|
||||
actor mapped and realized (if it was before) until it has a
|
||||
new parent, at which point the invariants implied by the new
|
||||
parent's state are applied. [DEPRECATED]
|
||||
|
||||
5) CLUTTER_ACTOR_IS_REALIZED(actor) => CLUTTER_ACTOR_IS_REALIZED(parent)
|
||||
|
||||
Actors may only be realized if their parent is realized.
|
||||
However, they may be unrealized even though their parent
|
||||
is realized.
|
||||
|
||||
This implies that an actor may not be realized unless
|
||||
it has a parent, or is a toplevel.
|
||||
|
||||
Since only toplevels can realize without a parent, no actor
|
||||
can be realized unless it either is a toplevel or has a
|
||||
toplevel ancestor.
|
||||
|
||||
As long as they are unmapped, actors may be unrealized. This
|
||||
will force all children of the actor to be unrealized, since
|
||||
children may not be realized while parents are unrealized.
|
||||
|
||||
6) CLUTTER_ACTOR_IS_MAPPED(actor) <=>
|
||||
( ( (CLUTTER_ACTOR_IS_VISIBLE(toplevel_parent) &&
|
||||
CLUTTER_ACTOR_IS_REALIZED(toplevel_parent)) ||
|
||||
CLUTTER_ACTOR_IS_MAPPED(non_toplevel_parent) ) ) &&
|
||||
CLUTTER_ACTOR_IS_VISIBLE(actor)
|
||||
|
||||
Actors _must_ be mapped if and only if they are visible and
|
||||
their parent is mapped, or they are visible and their
|
||||
parent is a toplevel that's realized and visible.
|
||||
|
||||
This invariant enables us to track whether an actor will
|
||||
be painted (whether it's MAPPED) without ever traversing
|
||||
the actor graph.
|
||||
|
||||
iii. State changes
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
clutter_actor_show:
|
||||
1. sets VISIBLE
|
||||
2. sets MAPPED if invariants are met; mapping in turn sets
|
||||
REALIZED
|
||||
|
||||
clutter_actor_hide:
|
||||
1. sets !VISIBLE
|
||||
2. unsets MAPPED if actor was mapped previously
|
||||
3. does not affect REALIZED
|
||||
|
||||
clutter_actor_destroy:
|
||||
1. sets CLUTTER_ACTOR_IN_DESTRUCTION
|
||||
2. unparents the actor, which in turn implies unmap and unrealize
|
||||
|
||||
clutter_actor_realize:
|
||||
1. attempts to set REALIZED on all parents, failing if
|
||||
invariants are not met, e.g. not in a toplevel yet
|
||||
2. sets REALIZED on actor if parent was successfully realized
|
||||
|
||||
clutter_actor_unrealize:
|
||||
1. sets !VISIBLE which forces !MAPPED
|
||||
2. sets !REALIZED
|
||||
3. !MAPPED and !REALIZED forces unmap and unrealize of all
|
||||
children
|
||||
|
||||
clutter_actor_add_child:
|
||||
1. sets actor->parent
|
||||
2. if actor->show_on_set_parent is TRUE calls clutter_actor_show
|
||||
3. sets MAPPED if all prerequisites are now met for map
|
||||
4. if !CLUTTER_ACTOR_IN_REPARENT emits ::parent-set with
|
||||
old_parent set to NULL
|
||||
|
||||
clutter_actor_remove_child:
|
||||
1. unsets actor->parent
|
||||
2. if !CLUTTER_ACTOR_IN_REPARENT, sets !MAPPED and !REALIZED
|
||||
since the invariants for those flags are no longer met
|
||||
3. if !CLUTTER_ACTOR_IN_REPARENT emits ::parent-set with
|
||||
old_parent set to the previous parent
|
||||
|
||||
clutter_actor_reparent: [DEPRECATED]
|
||||
1. sets CLUTTER_ACTOR_IN_REPARENT
|
||||
2. emits ::parent-set with old_parent set to the previous parent
|
||||
equivalent to:
|
||||
clutter_actor_unparent
|
||||
clutter_actor_set_parent
|
||||
3. updates state of the actor to match invariants
|
||||
(may change MAPPED or REALIZED in either direction,
|
||||
depending on state of the new parent)
|
||||
|
||||
|
||||
iv. Responsibilities of a ClutterActor
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
a. Adding to a container
|
||||
|
||||
When adding an actor to a container, the container must:
|
||||
|
||||
1. call clutter_actor_add_child (container, actor)
|
||||
|
||||
b. Removing from a container
|
||||
|
||||
When removing an actor from a container, the container must:
|
||||
|
||||
1. call clutter_actor_remove_child (container, actor)
|
||||
|
||||
c. Initial state
|
||||
|
||||
When creating an actor, the initial state is:
|
||||
|
||||
1. !CLUTTER_ACTOR_REALIZED
|
||||
2. !CLUTTER_ACTOR_MAPPED

Structure
|
||||
---------
|
||||
|
||||
The stylesheet is divided into the following sections:
|
||||
|
||||
Positioning
|
||||
Margins, paddings, width, font-size, clearing.
|
||||
Decorations
|
||||
Borders, style
|
||||
Colors
|
||||
Colors
|
||||
Graphics
|
||||
Graphical backgrounds
|
||||
Nasty IE tweaks
|
||||
Workarounds needed to make it work in internet explorer,
|
||||
currently makes the stylesheet non validating, but up until
|
||||
this point it is validating.
|
||||
Mozilla extensions
|
||||
Transparency for footer
|
||||
Rounded corners on boxes

<filename>doc/cookbook</filename> inside the Clutter source directory.</para>
|

|

<para>To maintain some degree of consistency, try to stick to the
|
||||
following broad guidelines about how to write Docbook for this
|
||||
cookbook:</para>
|
||||
|
||||
<itemizedlist>
|
||||
<listitem>
|
||||
<para>If adding a new recipe, use the
|
||||
<filename>recipe-template.xml</filename> XML file as a basis.
|
||||
You can find it in the <filename><clutter source>/doc/cookbook/</filename>
|
||||
directory.</para>
|
||||
</listitem>
|
||||
<listitem>
|
||||
<para>Try to indent your XML sensibly using 2 spaces per level
|
||||
(we're not too strict, but some indentation helps reading
|
||||
the source).</para>
|
||||
</listitem>
|
||||
<listitem>
|
||||
<para>Stick to a column width of around 80 characters.</para>
|
||||
</listitem>
|
||||
<listitem>
|
||||
<para>Use the <filename> element for file
|
||||
and directory names.</para>
|
||||
</listitem>
|
||||
<listitem>
|
||||
<para>Use the <property> element for property names
|
||||
(e.g. GObject properties).</para>

</listitem>
|

you are referring to what's actually printed on the key, e.g.
|

<keycap>Shift</keycap>. If you're referring to the key some
|

other way (e.g. "the Control key"), don't use
|

<keycap>.</para>
|
||||
</listitem>
|
||||
<listitem>
|
||||
<para>Use the <function> element for functions;
|

<listitem>
|

<para>To include a video in a recipe, do the following:</para>
|

<para>To include a full code sample in a recipe (which can
|

be compiled into a runnable binary), do the following:</para>
|
||||
|
||||
<itemizedlist>
|
||||
<listitem>
|
||||
<para>Create a C code file in the
|
||||
<filename><clutter source>/doc/cookbook/examples</filename>
|
||||
directory. It should be a standalone C application (with
|
||||
a <function>main()</function> etc.). The filename should be
|
||||
in the format
|
||||
<filename><section>-<recipe>.c</filename>; you
|
||||
can add an optional identifier to the end if you have more
|
||||
than one example for a recipe.</para>
|
||||
|
||||
<para>If you want to load image files into the application
|
||||
(e.g. to demonstrate something with a texture), you can use
|
||||
the <constant>TESTS_DATA_DIR</constant> variable in your C
|
||||
code to reuse images in the Clutter <filename>tests</filename>
|
||||
directory; this will be replaced with
|
||||
<filename><clutter source>/tests/data</filename>
|
||||
during the build. For example:</para>
|
||||
|
||||
<informalexample>

<![CDATA[

<listitem>
|

<para>Edit <filename>Makefile.am</filename>
|

in the <filename>cookbook/examples</filename> directory
|

so that the build recognises the new code; e.g. if
|

your C source file were called
|

<filename>fooing-barring.c</filename> you would do:</para>

|

<para>Let me show you that easy way, so others may easily follow.</para>
|
||||
</epigraph>
|
||||
|
||||
<para>There is a wonderful simile in the preface of the <emphasis>Perl
|
||||
Cookbook</emphasis>: approaching a programming problem is oftentimes
|
||||
similar to balancing Columbus's egg. The initial difficulties of dealing
|
||||
with, and more importantly solving, problems in the software engineering
|
||||
field sometimes can only be overcome if somebody shows you how to use a
|
||||
new tool. This is true for programming languages but also for programming
|
||||
libraries.</para>
|
||||
|
||||
<para>This book has been written to try and give you a reference on
|
||||
how to solve common issues that you might have to face when using
|
||||
the Clutter toolkit.</para>
|
||||
|
||||
<para>This book is not meant to be a replacement for the Clutter API
|
||||
reference, even though there will be descriptions of how Clutter works
|
||||
and how its API looks like. We will require knowledge of the Clutter API,
|
||||
but we will also point out where to find more information on the API that
|
||||
examples have used.</para>
|
||||
|
||||
<para>Indeed, this book should be used as a companion to the API reference,
|
||||
expanding its examples and showing how to achieve a specific result.</para>
|
||||
|
||||
<para>This is not a book for learning Clutter. This is also not a book
|
||||
for learning C, or GObject or even GUI development.</para>
|
||||
|
||||
<para>Above all, this is a book for learning <emphasis>more</emphasis>
|
||||
about Clutter, and about how to use it in the most efficient and easiest
|
||||
way. It is meant to help you move past the basic usage of Clutter.</para>
|
||||
|
||||
<para>This book is divided into chapters. Each chapter is dedicated to
|
||||
a specific class, like ClutterTexture, or a specific area, like animations.
|
||||
Each chapter starts with a short introduction, followed by different
|
||||
<emphasis>recipes</emphasis>. Each recipe starts with a problem, or a short
|
||||
statement describing what we want to achieve; a solution, containing the
|
||||
source code; and a discussion section, where the code is explained, where
|
||||
alternative approaches might be useful, and where caveats and references to
|
||||
the Clutter API for further studying can be found.</para>
|
||||
|
||||
<para>This book, in the cookbook spirit, can be accessed mostly at
|
||||
random.</para>
|
||||
|
||||
<section>
|
||||
<title>About Clutter</title>
|
||||
|
||||
<para>Clutter is an free and open source software library for creating
|
||||
portable, dynamic, compelling and fast graphical user interfaces.</para>
|
||||
|
||||
<para>Clutter uses OpenGL (and, optionally, OpenGL ES on mobile and
|
||||
embedded platforms) for rendering the user interface elements, but
|
||||
at the same time it exposes an application program interface that hides
|
||||
the underlying complexity of the OpenGL state machine from the
|
||||
developer.</para>
|
||||
|
||||
<para>The program interface of Clutter is intended to be easy to use,
|
||||
efficient, flexible and as self-documenting as possible.</para>
