The ClutterBox::add method is a simple wrapper around the Container
add_actor() method and the LayoutManager layout properties API. It
allows adding an actor to a Box and setting the layout properties in
one call.
If the LayoutManager used by the Box does not support layout properties
then the add() method short-circuits out.
Along with the varargs version of the method there's also a vector-based
variant, for language bindings to use.
Instead of overloading ClutterChildMeta with both container and layout
metadata and delegate to every LayoutManager implementation to keep a
backpointer to the layout manager instance, we can simply subclass
ChildMeta into LayoutMeta and presto! everything works out pretty well
for everyone.
Each actor managed by a BinLayout policy should reside inside its
own "layer", with horizontal and vertical alignment. The :x-align
and :y-align properties of the BinLayout are the default alignment
policies, which are copied to each new "layer" when it is created.
The set_alignment() and get_alignment() methods of BinLayout can
be changed to operate on a specific "layer".
The whole machinery uses the new ChildMeta support inside the
LayoutManager base abstract class.
The ChildMeta object is a storage for child-container properties,
that is properties that exist only when an actor is inside a specific
container. The LayoutManager delegate class should also have
layout-specific properties -- so, for this job, we can "recycle"
ChildMeta as the storage.
Emit the ::layout-changed when the BinLayout alignment policies change.
This will result in a queue_relayout() on the containers using the
BinLayout layout manager.
* Use ::layout-changed to queue a relayout when the layout changes
* Destroy the Box children when destroying the Box
* Allow getting the layout manager from the Box
If a sub-class of LayoutManager wishes to implement a parametrized
layout policy it also needs a way to notify the container using the
layout manager that the layout has changed. We cannot do it directly
and automatically from the LayoutManager because a) it has no back
link to the actor that it is using it and b) it can be attached to
multiple actors.
This is a job for <cue raising dramatic music> signals!
By adding ClutterLayoutManager::layout-changed (and its relative
emitted function) we can notify actors using the layout manager that
the layout parameters have been changed, and thus they should queue
a relayout.
A BinLayout is a simple layout manager that allocates a single cell,
providing alignment on both the horizontal and vertical axis.
If the container associated to the BinLayout has more than one child,
the preferred size returned by the layout manager will be as big as
the maximum of the children preferred sizes; the allocation will be
applied to all children - but it will still depend on each child
preferred size and the BinLayout horizontal and vertical alignment
properties.
The supported alignment properties are:
* center: align the child by centering it
* start: align the child at the top or left border of the layout
* end: align the child at the bottom or right border of the layout
* fill: expand the child to fill the size of the layout
* fixed: let the child position itself
A layout manager instance makes only sense if it's owned by a
container. For this reason, it should have a floating reference
instead of a full reference on construction; this allows constructing
Boxes like:
box = clutter_box_new (clutter_fixed_layout_new ());
without leaking the layout manager instance.
The LayoutManager class is an abstract proxy for the size requesition
and size allocation process in ClutterActor.
A ClutterLayoutManager sub-class must implement get_preferred_width(),
get_preferred_height() and allocate(); a ClutterContainer using the
LayoutManager API will then proxy the corresponding Actor virtual
functions to the LayoutManager instance. This allows having a generic
"blank" ClutterActor sub-class, implementing the ClutterContainer
interface, which leaves only the layout management implementation to
the application developers.
The rules to create signal marshallers and enumeration GTypes are
usually copied and pasted all over different projects, though they
are pretty generic and, given a little bit of parametrization, can
be put in separate Makefile.am files and included whenever needed.
The set_default_stage() method of StageManager should not be used
by application code; technically, nothing in Clutter uses it, and
StageManager's API is not considered public anyway.
The IN_DESTRUCTION flag is set around the unrealization and disposal of
the actor in clutter_actor_destroy() but is never unset (it's set twice
instead).

Currently, setting the :text property has the side-effect of
setting the :use-markup property to FALSE. This prevents
constructing a Text actor, or setting its properties, like:
g_object_set (text,
"use-markup", TRUE,
"text", some_string,
NULL);
as the ordering becomes important. Unfortunately, the ordering
of the properties cannot be enforced with ClutterScript or
with language bindings.
The documentation of the clutter_text_set_text() method should
be expanded to properly specify that the set_text() method will
change the :use-markup property to FALSE as a side effect.
Transform functions allow the use of g_value_transform() to cast

Current parsing of units has a number of shortcomings:
* a number followed by trailing space (without any unit specified) was
not recognized,
* "5 emeralds" was parsed as 5em,
* the way we parse the digits after the separator makes us lose
precision for no good reason (5.0 is parsed as 5.00010014...f which
makes g_assert_cmpfloat() fail)

ClutterGroup previously calculated the size as the distance from the

child except if there were any chidren left of the origin then the

However the group is always allocated its size relative to its

the preferred size would not be large enough to reach the rightmost

Since the Great Rework of ClutterUnits, functions have been using
'units' not 'unit' in their name. clutter_value_get_unit() is a left
over from a dark age, its declaration and documentation have been
updated but not the symbol itself.
Instead of having an assertion failure with a message of dubious
usefulness, we should probably use a more verbose warning explaining
what is the problem and what might be the cause.
The user-initiated resize is conflicting with the allocated size. This
happens because we change the size of the stage's X Window behind the
back of the size allocation machinery.
Instead, we should change the size of the actor whenever we receive a
ConfigureNotify event to reflect the new size of the actor.
We force the redraw before mapping, in the hope that when a composited
window manager maps the window it will have its contents ready; that is
not going to work: the solution for this problem requires the implementation
of a protocol for compositors, and not a hack.
Moreover, painting before mapping will cause a paint with the wrong
GL viewport size, which is the wrong thing to do on GLX.
When not building a debug build the compiler was warning about empty
else clauses with no braces due to code like:

glVertexPointer expects positions with 2, 3 or 4 components, glColorPointer

"gl_Vertex", "gl_Color" or "gl_Normal" we assert these constraints and print
an explanation to the developer if not met.

must have n_components == 1; thanks to Cat Sidhe for reporting this:

Now if you export CLUTTER_DEBUG=dump-pick-buffers clutter will write out a
png, e.g. pick-buffer-00000.png, each time _clutter_to_pick() is called.
It's a rather crude way to debug the picking (realtime visualization in a
second stage would probably be nicer) but it we've used this approach
successfully numerous times when debugging Clutter picking issues so it
makes sense to have a debug option for it.
It looks like the intention was to duplicate an XVisualInfo in such a way
that the pointer could be returned and then later freed using XFree. But
Xalloc isn't an Xlib counterpart to XFree; Xlib doesn't provide a general
purpose malloc wrapper afik. By shuffling things about a bit, it was
possible to avoid the need for this hack.
By default, float * is considered as an out argument by gobject
introspection which is wrong for quite a few Cogl symbols. Start adding

In the default implementation of container::destroy_child_meta Set child
meta qdata to NULL on the child and not the container, since the child

The lifetime of the journal VBO is entirely within the scope of the
cogl_journal_flush function so there is no need to store it globally
in the Cogl context. Instead, upload_vertices_to_vbo just returns the
new VBO. cogl_journal_flush stores this in a local variable and
destroys it before returning.
This also fixes an assertion when using the GLES backend which was
caused by nothing initialising the journal_vbo variable.

The framebuffer_object spec isn't clear in defining whether attaching a
texture as a renderbuffer with mipmap filtering enabled while the mipmaps
have not been uploaded should result in an incomplete framebuffer object.
(different drivers make different decisions)
To avoid an error with drivers that do consider this a problem we explicitly
set non mipmapped filters before calling glCheckFramebufferStatusEXT. The
filters will later be reset when the texture is actually used for rendering
according to the filters set on the corresponding CoglMaterial.
Since an actor can only be parented to one container we don't need
the extra complications of maintaining a list of ChildMeta objects
attached to an actor in the default implementation of the Container
interface.
Instead of using ClutterActor for the base class of the Stage
implementation we should extend the StageWindow interface with
the required bits (geometry, realization) and use a simple object
class.
This require a wee bit of changes across Backend, Stage and
StageWindow, even though it's mostly re-shuffling.
First of all, StageWindow should get new virtual functions:
* geometry:
- resize()
- get_geometry()
* realization
- realize()
- unrealize()
This covers all the bits that we use from ClutterActor currently
inside the stage implementations.
The ClutterBackend::create_stage() virtual function should create
a StageWindow, and not an Actor (it should always have been; the
fact that it returned an Actor was a leak of the black magic going
on underneath). Since we never guaranteed ABI compatibility for
the Backend class, this is not a problem.
Internally to ClutterStage we can finally drop the shenanigans of
setting/unsetting actor flags on the implementation: if the realization
succeeds, for instance, we set the REALIZED flag on the Stage and
we're done.
As an initial proof of concept, the X11 and GLX stage implementations
have been ported to the New World Order(tm) and show no regressions.
The old code checked whether the property began with 'signal-' and
then checked for 'signal-swapped' and 'signal-after'. This prevented
you from animating a property called for example 'signal-strength'.
The check for the prefix is now in a separate function which also adds
a 'signal-swapped-after' prefix for completeness.

The default floating point type for JSON is double precision; this means
that we need to conver to single precision when setting a property with
type G_TYPE_FLOAT.
Currently, to update a property inside an animation you have to
get the interval for that property and then call the set_final_value()
method.
We can provide a simpler, bind()-like method for the convenience of
the developers that just validates everything and then calls the
Interval.set_final_value().
Right now we just check for a NULL stage before calling glXMakeCurrent().
We can, though, get a valid stage without an implementation attached to
it while we are disposing a stage after a CLUTTER_DELETE event, since the
events processing is performed on a vblank-locked basis.
ClutterClone bases its preferred size on the preferred size of
the source actor, so it needs to invalid its cached preferred
size when the preferred size of the source actor changes.
In order for this to work, we need to have notification when
the size of the source actor changes, so add a ::queue-relayout
signal to ClutterActor.
Then connect to this from ClutterClone and queue a relayout
on the clone when a relayout is queued on the source.

When a letter key is pressed with the control key held down one of
three things will happen :-
a) If the stage is embedded within a GtkClutterEmbed the unicode value
will be filled from gdk_keyval_to_unicode. This will be the same
value as if control was not pressed (so Ctrl+V will be 'v').
b) If the stage is not in a GtkClutterEmbed and Clutter is running on
the X11 backend then it will try to fill in the unicode value from
XLookupString. This *will* take into account the control so the
unicode value will represent a control character (Ctrl+V will be
'\x16').
c) Most other backends will not bother to fill in the unicode
value. Therefore clutter_keysym_to_unicode will be used which also
does not take into account the control key (so Ctrl+V will be 'v').
For cut and paste to work in Nbtk, the control keys need to bubble up
to the parent NbtkEntry container. This works fine for 'b' but not 'a'
and 'c'.
This patch makes ClutterText always allow the event to bubble if the
key is not handled by the binding pool and the control modifier is
down.
Ideally ClutterText would always get a unicode value that takes into
account the modifiers but this is probably best left up to the input
methods.

When dumping a ClutterUnits structure to a string we are using a bare
g_strdup_printf(), which unfortunately is locale dependant. So, for

as:
C: 42.00 em
en_GB 42.00 em
it_IT 42,00 em
fr_FR 42,00 em
This would not be a problem -- clutter_units_from_string() allows both
'.' and ',' as fractionary part delimiters. The test suite, on the
other hand, does not know that, and it checks for exact matches with
the C locale.
Calling setlocale(LC_ALL,"C") at the beginning of the conformance test
suite is not a good idea, because it would prevent external testing; and
it's a lame cop out from doing exactly what we have to do -- pick a format
and stick with it.
Like other platforms, languages and frameworks before us, we opt to
be less liberal in what we create; so, we choose to always stringify
ClutterUnits with fractionary parts using '.' as the delimiter.

Clutter advertises itself on X11 as implementing the _NET_WM_PING protocol,
which is needed to be able to detect frozen applications; this allows us to
stop the destruction of the stage by blocking the CLUTTER_DELETE event and
wait for user feedback without the Window Manager thinking that the app has
gone unresponsive.
In order to implement the _NET_WM_PING protocol properly, though, we need
to add the _NET_WM_PID property on the Stage window, since the EWMH states:
[_NET_WM_PID] MAY be used by the Window Manager to kill windows which
do not respond to the _NET_WM_PING protocol.
Meaning that an unresponsive Clutter application might not be killable by
the window manager.

It is possible to unset the size of an actor specified with set_width()
and set_height() by using:
clutter_actor_set_size (actor, -1, -1);
Which works by unsetting the :min-*-set and the :natural-*-set properties.
Calling set_width(-1) and set_height(-1) separately, though, doesn't work
thus implicitly breaking the assumption that set_size() is nothing more
than set_width()+set_height(). This was obviously due to the face that
pre-1.0 set_width() and set_height() took an unsigned integer as an
argument.
ClutterActor parses positional and dimensional properties with a
custom deserializer. We need to:
- handle G_TYPE_INT64, the default integer type for JSON-GLib
- use G_TYPE_FLOAT for properties, since Actor switched to it
for the pixel-based ones
This makes ClutterScript work again.
The json-types.h header is found by the mere fact of it being
in the project; if we are compiling against the system JSON-GLib
this could be horribly out of date.
We need to use clutter-json.h, which will include the right
header for us.
JSON-GLib moved to a single include scheme, so we should only include
json-glib.h. If we use the internal copy it doesn't matter, since the
header does the right thing.
The clutter-script-parser.c does not have a copyright and license
notices; even though the LGPL is a per-project license and not a
per-file license, having those notices in every source file is a
good idea.
The OS X backend Makefile.am was missing a line concatenation, and
so the -xobjective-c directive was always ignored.
Instead of dumping everything into INCLUDES and LDADD we should follow

The fix for bug 1750 inside commit b190448e made Clutter-GTK spew
BadWindow errors. The reason for that is that we call XDestroyWindow()

been realized.
Since Clutter-GTK does not need to realize the Stage it is going to
embed anymore (the only reason for that was to obtain a proper Visual
but now there's ClutterBackendX11 API for that), the set_stage_foreign()
call is effectively setting the StageX11 Window for the first time.
When we replace the stage Window using a foreign one we also need to
destroy the Window we created, if needed, to avoid leaking resources
all around.

The "catch all" warning for a the mapped invariant violation is too
generic: it doesn't tell you why the invariant was broken in case
we are trying to map an unparented actor - e.g. through a Clone.
The right gcc define is __GNUC__ not __GNUC_. This typo had the side
effect that we were using the non gcc specific debug macros leading to
a less optmised CLUTTER_NOTE () than one could have dreamed of.
The vertex that should be used by the apply_relative_transform
is the one passed in as const, and the result should be placed
inside the non-const ClutterVertext. Currently, we are using
the latter, and thus the function is completely useless.
We should follow the convention for boxed types initializers of:
<type_name>_from_<another_type> (boxed, value)
For ClutterUnits as well; so:
clutter_units_pixels -> clutter_units_from_pixels
clutter_units_em -> clutter_units_from_em
...
We should still keep the short-hand version as a macro, though.
This makes clutter_stage_win32_show/hide be implementations of
ClutterStageWindowIface rather than overriding the methods in
ClutterActor. This reflects the changes in e4ff24bc for the X11

In case we are skipping too many frames, we should force the animation
instance to apply the final state of the animated interval inside the

If you select all the text in a ClutterText, there is an invisible
cursor position either at the beginning or end. If it's at the beginning,
the bug is that left arrow won't clear the selection. If it's at the end,
the bug is that the right arrow won't.
Here are the ways to reproduce it:
a. Ctrl-A selects all and moves the hidden cursor position to the left.
b. For single line: End, Shift-Home does the same.
c. Or manually moving to the end and doing Shift-Left Arrow to the
beginning.
These all put it in the state where right arrow will properly clear
selection and move to cursor position 1, but left arrow fails to clear
the selection.
For b and c above, the opposite will give you the end case where right
arrow doesn't work.
Anyway, it turns out clear_selection is getting called, it just doesn't
show up because it's not doing a queue_redraw. So the attached patch
