Previously when the markup property is set it would generate an
attribute list from the markup and then merge it with the attributes
from the attribute property and store it as the effective
attributes. The markup attributes and the marked up text would then be
forgotten. This breaks if the application then later changes the
attributes property because it would try to regenerate the effective
attributes from the markup text but the stored text no longer contains
any markup. If the original markup text happened to contain entities
like '<' they would end up causing parse errors because they would
be converted to the actual symbols.
To fix this the attributes from the markup are now stored
independently from the effective attributes. The effective attributes
are now regenerated if either set of attributes changes right before a
layout is created.

cogl_clip_push, and cogl_clip_push_window_rect which are now deprecated were
used in various places internally so this just switches to using the
replacement functions.
The change in commit 3bbc96e17e moved the
:text property setter to use set_text_internal(); this function does not
invalidate the Layout cache and does not queue a relayout, thus breaking
the behaviour of ClutterText when setting the contents of the actor using
the property.

Input Methods require to be able to set a "pre-edit string", that is
a string that it's just displayed into the Text actor without being
committed to the actor's buffer. The string might require custom Pango
attributes, and an update of the cursor position.
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.
clutter_text_move_word_backward/forward() calls did not use the
start argument consistently. Also, clutter_text_move_word_forward()
bound check checked the wrong end.

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.

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
seems to fix things.

ClutterEvent is not really gobject-introspection friendly because
of the whole discriminated union thing. In particular, if you get
a ClutterEvent in a signal handler, you probably can't access the
event-type-specific fields, and you probably can't call methods
like clutter_key_event_symbol() either, because you can't cast the
ClutterEvent to a ClutterKeyEvent.
The cleanest solution is to turn every accessor into ClutterEvent
methods, accepting a ClutterEvent* and internally checking the event
type.

Instead of passing a boolean value, the ::allocate virtual function
should use a bitmask and flags. This gives us room for expansion

The cursor x position is already translated, so we do not need to take the
actors allocation into account when calculating scrolling.
Additionally, we need to update the text_x value before running
clutter_text_ensure_cursor_position.
Add any scrolling offset to the x value when in single line mode.
Now that the offset is taken into account in the position_to_coords
function, we do not need to adjust the cursor x manually in
clutter_text_paint.
If the cursor is already at the end of the Text contents then we
need to maintain its position when deleting the previous character
using the relative key binding.
If text is set, ClutterText should never return less than the layout
height for minimum and preferred heights.
This holds unless ellipsize and wrap are enabled, in which case the
minimum height should be the height of the first line -- which is
the height needed to at the very least show the ellipsization.

With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.
ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.
So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:
- we have to maintain twice the amount of entry points in ClutterActor
- we still do an integer-to-float implicit conversion
- we introduce a weird impedance between pixels and "pixels with
fractionary bits"
- language bindings will have to choose what to bind, and resort
to manually overriding the API
+ *except* for language bindings based on GObject-Introspection, as
they cannot do manual overrides, thus will replicate the entire
set of entry points
For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:
void clutter_actor_set_x (ClutterActor *self,
gfloat x);
void clutter_actor_get_size (ClutterActor *self,
gfloat *width,
gfloat *height);
gfloat clutter_actor_get_height (ClutterActor *self);
etc.
The issues I have identified are:
- we'll have a two cases of compiler warnings:
- printf() format of the return values from %d to %f
- clutter_actor_get_size() taking floats instead of unsigned ints
- we'll have a problem with varargs when passing an integer instead
of a floating point value, except on 64bit platforms where the
size of a float is the same as the size of an int
To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:
- we remove ambiguity in the API with regard to pixels and units
- we remove entry points we get to maintain for the whole 1.0
version of the API
- we make things simpler to bind for both manual language bindings
and automatic (gobject-introspection based) ones
- we have the simplest API possible while still exposing the
capabilities of the underlying GL implementation
Setting the wrap mode on the PangoLayout seems to have disappeared
during the text-actor-layout-height branch merge so this brings it
back. The test for this in test-text-cache no longer needs to be
disabled.
We also shouldn't set the width on the layout if there is no wrapping
or ellipsizing because otherwise it implicitly enables wrapping. This
only matters if the actor gets allocated smaller than its natural
size.
The documentation for the ::cursor-event says that the signal
is emitted only when the cursor position changes. Right now it
is being emitted every time we ensure the cursor position during
the Text paint sequence.
The clutter_text_ensure_cursor_position() function should check
whether the stored cursor position has changed since the last
paint, and emit the ::cursor-event signal only when there has
been a change.
We only want to eschew the pango_layout_set_width() on editable,
single-line Text actors because they can "scroll" the PangoLayout.
This fixes the ellipsization on entries.
Editable ClutterText will scroll when allocated less width than is
necessary to lay out the entire layout on a single line, so return 1 for
the minimum width in this case.
Approved by Emmanuele Bassi, fixes bug #1555.
Ellipsizing was effectively broken for two reasons. There was a typo
in the code to set the width so it always ended up being some massive
value. If no height should be set on the layout it was being set to
G_MAXINT. Setting a height greater than 0 enables wrapping which so
ellipsizing is not performed. It should be left at the default of -1
instead.
Adds a new property so that the selection color can be different from
the cursor color. If no selection color is specified it will use the
cursor color as before. If no cursor color is specified either it will
use the text color.
Bug 1518 - [Patch] Widget derivied from ClutterText will crash on
key_press_event
In clutter_text_key_press() we are using G_OBJECT_TYPE_NAME to find
out the actor's type name. However, if some widget is derived from
ClutterText, when the key press handler is called, G_OBJECT_TYPE_NAME
will return the name of the derived widget.

ClutterText should offer multiple selection modes depending on the
number of pointer clicks.
Following the GTK+ conventions:
- double click selects the current word
- triple click selects the current line
Bug 1529 - Selection bound out of sync with an empty Text actor
When the user clicks on a Text actor the cursor position and the
selection bound are set using bytes_to_offset(); if the Text is
empty, this means placing them both to 0. Setting the selection
bound to 0 means that when the user inserts a character by typing
it into the Text, the selection will be [0,1]; this will select
the first character, which will then be overwritten when typing
a new character.
The Text actor should, instead, check if there are no contents
and set the cursor position and the selection bound to -1.
The clutter_text_set_selection_bound() method should also validate
the value passed, in case it's bigger than the text lenght, or
smaller than -1.
As a convenience, if NULL is passed for the text argument of
clutter_text_set_text() (and for consistency,
clutter_text_set_markup()), treat that the same as "".
Bug 1501 - clutter_text_insert_text not working right with non-onebyte

The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.
Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.
See bug 1428:
http://bugzilla.openedhand.com/show_bug.cgi?id=1428
ClutterText should merge the PangoAttributes set by using
clutter_text_set_attributes() with the attributes generated by
parsing Pango markup.
For this to work we must parse the markup and merge the attributes
we get out of pango_parse_markup() with the attributes set by
the user.
Setting the markup or the attributes on an editable text should
not work for the time being.
This makes it consistent with cogl_rectangle_with_{multi,}texture_coords.
Notably the reason cogl_rectangle_with_{multi,}texture_coords wasn't changed
instead is that the former approach lets you describe back facing rectangles.
(though technically you could pass negative width/height values to achieve
this; it doesn't seem as neat.)
Whenever a ClutterText is created it now connects to the font-changed
signal. When it is emitted the layout cache is dirtied and a relayout
is queued. That way changes to the font options or resolution will
cause an immediate update to the labels in the scene.
ClutterText already has code to try to preserve the x position when
moving up or down. A target x-position is stored and the cursor is
positioned at the nearest point to that in the appropriate line when
up or down is pressed. However the target position was never cleared
so it would always target the x-position of the cursor from the first
time you pressed up or down.
To fix this the patch clears the target position in set_position and
then sets it after the call in real_move_up/down. That way pressing
up or down sets the target position and any other movement will clear
it.
To get an index for the pixel position in the line
pango_layout_line_x_to_index is used. However when x is greater than
the length of the line then the index before the last grapheme is
returned which was causing it to jump to the penultimate
character. The patch makes it add on the trailing value so that it
will jump to the last character.
The old function ended up returning the length of the string when pos
was zero. This caused it to insert characters at the end when the
cursor was at the beginning of the string.
If an unbound control key is pressed (such as Ctrl+R) it would insert
a rectangle into the text.
Also zero is considered a valid unicode character by
g_unichar_validate so pressing a key such as shift would cause the
current selection to be deleted. The character isn't actually inserted
because insert_unichar disallows zeroes.
Some of the read-write properties of ClutterText were missing
an implementation in clutter_text_get_property(), as well as
the :position and :selection-bound properties being wrongly
converted from fixed point to integer, passing through floating
point values.
An editable ClutterText should not use pango_layout_set_markup(),
as the contents of the text actor will not match the text.
Only read-only text actors should parse the contents for Pango
markup.
If the Text actor is neither editable nor has its cursor set
to visible, then we should not be ensuring the cursor position.
This fixes a failure in the conformance test unit for the
layout cache.

The cursor should be slightly smaller than the height of the actor, to
allow for painting a border. Let's pad it by 1 pixel on the top and 1
on the bottom.
Also, we should use the cursor size everywhere and not use hardcoded
magic numbers.
Allow using ClutterText as a single line text field. This is useful for
text fields that accept just a single line of contents by default, and
respond to the Enter key press to execute some action.
The :single-line-mode property enables this behaviour inside ClutterText
by clipping and scrolling the contents of the PangoLayout if they do
not fit the allocated width of the Text actor.
When using the delete-prev action from the end of the text we end
up either missing the first glyph we have to delete or falling
through the last one in the text.
This commit fixes both issues.
Since clutter_text_set_text() measures the length of the text
each time, we should use the cached length instead of recomputing
the text length each time. This should save us some time when
dealing with long, multi-byte texts.
Using two properties to set a password entry can be construed as
both cumbersome and a gtk-ism. And rightly so on both counts.
The :text-visible property has also conflicting semantics with the
:cursor-visible one: while the latter hides the cursor, the former
changes the display of the contents of the Text actor. It is, thus,
not a matter of "visibility" but of "rendering".
Instead of setting the :text-visible and :invisible-char properties
to have a password text field, the Text actor should just have a
single :password-char property holding a Unicode character. If the
value of the :password-char is non-zero, the Text actor will use the
Unicode character to render the contents of the text entry.
This commit removes the following methods:
clutter_text_set_text_visible()
clutter_text_get_text_visible()
clutter_text_set_invisible_char()
clutter_text_get_invisible_char()
And the following properties:
ClutterText:text-visible
ClutterText:invisible-char
In favour of:
clutter_text_set_password_char()
clutter_text_get_password_char()
And:
ClutterText:password-char
Thus making obvious what use the property and accessor methods are
for and simplifying the process of creating a simple password text
field to:
text = clutter_text_new ();
clutter_text_set_password_char (CLUTTER_TEXT (text), '*');
Instead of storing the default font name and size as a pre-processor
macro, use the newly added ClutterBackend API to retrieve the current
default font from the backend.
This follows the convention of GtkLabel/GtkEntry in GTK+ and the old
ClutterEntry.
It makes it easier to use strlen/strcmp etc on the output, since we can
assume that it is always a string.
This commit also updates the test unit for ClutterText to verify that
the clutter_text_get_text() function also returns an empty string when
a ClutterText actor has been created.
The clutter-private.h header already includes cogl-pango.h with
the correct inclusion path, because the main context stores a
pointer to the font map.
There is no need for clutter-text.c to include cogl-pango.h
again since it already includes clutter-private.h.
After fixing the cursor position issues around the initial
glyph of the layout, the selection position needs fixing as
well.
The fix is similar: check if the position of the selection
is 0 and provide a fast path by setting the offset to 0.
This is the port of the patch attached to bug 1266:
ClutterLabel support for pango_layout_set_height()
to the ClutterText actor. This patch adds support for the
pango_layout_set_height() function inside the layout creation
and caching, so that setting the height of a ClutterText will
make PangoLayout try to fill out the given height before
ellipsizing the contents of the ClutterText actor.
The original patch is from Havoc Pennington.
This commit ports the patch to ClutterText and applies a small
change to the height computation pointed out by Behdad Esfahbod
on GNOME's Bugzilla:
http://bugzilla.gnome.org/show_bug.cgi?id=560931
That the layout heights when doing a size request should be
set to be G_MAXINT instead of -1.
Unfortunately, the patch seems to break the conformance suite
when setting the ellipsization on the layout.
The clutter_text_set_selection() function is a convenience
method for setting the cursor position and the selection
boundary to a given position in a single call, with sanity
checks for the positions.
The clutter_text_get_selection() function was not checking the
passed argument, and was still accessing the contents of the
Text actor using clutter_text_get_text().
This commit also adds the last few gtk-doc annotations missing
from ClutterText.
Instead of repeating the same code for the ::activate signal
emission, use the clutter_text_activate() function inside the
'activate' key binding handler.
The clutter_text_activate() function will emit the ::activate
signal if the :activatable property is set.
This function is useful for subclasses or application code, for
example if we are going to use ::captured-event or ::key-press-event
signal handlers to intercept the Return key and emit the ::activate
signal ourselves.
Instead of installing the line-start and line-end key bindings
using the bare ClutterBindingPool API, we can use the internal
clutter_text_add_move_binding(), which automatically installs
the same key binding with the Shift modifier mask.
This allows selecting when pressing Shift+Home or Shift+End.
The selection behaviour is still incorrect around the zeroeth
position, with all the text after the first line being selected.
We can control the width of the cursor when painting by using
a simple property.
The magic -1 number passed to the setter method will reset the
cursor size to the default one of 2px.
The getter method will return an unsigned integer with the
current size.
Moving the text by a "page" depends on being able to define a
"page size" in terms of lines of text. Since we don't define
something similar to an Adjustment that allows us to handle this
behaviour, we should defer the paging implementation to a higher
level class based on ClutterText.
Another fix for the key navigation behaviour around the zeroeth
glyph in the layout.
This commit adds a fast path for for the zero index when the
cursor position is set as zero, in case we are using the line-start
or line-end key bindings, similarly to what we did in commit
be64cbcdc2 for the move-up and
move-down bindings.
The behaviour of ClutterText around the initial position is still
a little bit erratic.
This commit fixes the key navigation with Up and Down arrows around
the first line of text.
We loose precision with a direct conversion for PangoUnits to
pixels, so we should do the conversion as needed, inside the
callers of clutter_text_position_to_coords().
If we create the PangoContext for ClutterText inside the class
initialization we might not have a Clutter main context yet.
Ideally, we should store the Pango context inside the main context
and create it on clutter_init(), but for now we can lazily create
the PangoContext when we initialize a ClutterText instance for the
first time.
We allow KeyEvents with a key symbol of '0' to fall through only
if they are marked as synthetic. Otherwise we discard them without
mercy.
Synthetic events are useful to test ClutterText behaviour; in fact,
we do use them inside the test suite exactly for that reason.
I understand we are not Pascal developers, and we don't have to
use cute and cuddly names like "i_am_an_integer_counter", but
a ClutterButtonEvent should be stored inside an "event" variable.
Using "bev" instead? Mmmh, not so much.
ClutterText should use the paint opacity for both text and
cursor.
ClutterLabel had the wrong behaviour, as it set the actor's
opacity using the text color's alpha channel, and ClutterEntry
completely disregarded the actor's opacity when painting the
cursor.
This commit harmonizes the ClutterText behaviour to always
use a composition of the actor's paint opacity and the text
and cursor alpha channel values, thus behaving more
consistently with the rest of Clutter.
When inserting text on a key press event we should also truncate
the selection.
We should not truncate the selection when inserting any Unicode
character, since changing the selection also changes the cursor
position - and one of the invariants we inherited from ClutterEntry
is that inserting characters programmatically does not change the
cursor position.
If a selection has been truncated inside a key binding handler,
we should just return and let the usual key event handler continue.
This fixes the case where we deleted a selection using the Delete
or the Backspace keys.
ClutterText should use the newly added ClutterBindingPool API to
handle key events, instead of its homegrown code.
This commit removes the action/mapping code and defers the entire
key binding matching to a ClutterBindingPool created inside the
Text class initialization function.
The clutter_text_get_chars() function returns a section of the
contents of the Text actor, delimited by a start and an end position.
This commit adds the implementation for that function and a test
unit that guarantees the offset-to-bytes computations are correct.
The :cursor-color-set property is a read-only property that
reflects whether the ClutterText actor is going to use the
color set inside the :cursor-color property when painting
the cursor.
We should re-use the offset_to_bytes() implementation from ClutterEntry
as it guaranteed some behaviour and sanity checks that we want to keep
inside ClutterText.
A ClutterText can be put in "password mode" by setting the
text as "invisible": every character inside the Text actor's
contents will be replaced when building the Pango layout with
a specific Unicode character.
The Unicode character is set to '*' by default, but the user
can be changed using the provided API.
ClutterText should have the same properties as ClutterLabel.
While at it, we can finally fix the disconnect between the wrap
and wrap-mode properties and its accessors, that we perpetuated
from GtkLabel.
The ClutterText:line-wrap property and ClutterText:line-wrap-mode
are mapped to the set_line_wrap(), get_line_wrap() and
set_line_wrap_mode(), get_line_wrap_mode() accessor functions
respectively. This should simplify bindings the Vala ones that
map a property into a method.
ClutterText replaces ClutterLabel, so it should expose the same
kind of API - ideally with the minimal amount of changes, so that
the porting is trivial.
The TidyText actor is meant as a replacement for both ClutterLabel
and ClutterText.
Any text-displaying and editing actor should derive from ClutterText
and implement the various visual cues to differentiate the editable
from the non-editable state. Those visual cues usually belong to
a high-level toolkit, especially if themeing is involved.
