The :reactive property is used on StButton to like the :sensitive
property on GtkWidgets, that is, to indicate that the user is not
(yet) expected to click the button, and therefore should affect
styling too.
This allows to remove some code at the JS layer.

clutter_actor_get_children returns a newly allocated GList and it was
not freed.
However, as there's no reason to copy the children list, switch to
iterator api.

Commit de8a66d4ce removed our own DPI handling for the one found
it Clutter, but broke resolution updates at runtime (for instance

This swaps a use of GLfloat for a regular float. Cogl might stop
including a GL header in its public headers soon so this would fix a
compilation error.

Currently the scroll event code only handles scroll events if the
adjustment's value is within the "lower" and "upper" limits. The
likely intent was to pass events to a parent scroll view when
reaching the bounds (uh, nested scroll views!), but apparently
we never made use of this, as the upper bound is actually wrong
(an adjustment's maximum value is upper - page_size, not upper).
Just handle all scroll events unconditionally and rely on the
bound checks in StAdjustment.
https://bugzilla.gnome.org/show_bug.cgi?id=672413
Icon theme change signals aren't noticed immediately, they're usually
noticed when trying to load an icon. Since icon theme changes cause a
style change, and most icon widgets try to re-load their texture during
a style change, this means that we get a stack like this:
st_texture_cache_load_icon
gtk_icon_theme_lookup_icon
gtk_icon_theme_changed
st_widget_style_changed
st_texture_cache_load_icon
Rather than making every place that uses StTextureCache re-entrant,
punt the notifying of icon theme changes to an idle handler instead.
https://bugzilla.gnome.org/show_bug.cgi?id=673512
Currently compilation fails with -Werror, as we don't handle the
(newly introduced) smooth scroll events in switch statements; add
some basic support, which should make the compiler happy.
https://bugzilla.gnome.org/show_bug.cgi?id=672413
More than one outstanding request to the same URI should now be
deduplicated, and the framework is there if we want to cache async loaded
URIs as well
https://bugzilla.gnome.org/show_bug.cgi?id=672273
In the case that we don't have an icon corresponding to the gicon, it's
more than likely that the code calling load_gicon will know more about
what it wants as a fallback than the texture-cache itself. In fact -
we had a whole lot of dead code that would try to fall back, but never
did because we always returned a valid actor.
This was causing certain applications with invalid icons to not get the
fallback icon because an icon couldn't be found. Fix up the one place
where we don't have an explicit fallback icon codepath, and then stop
doing what we were doing.
https://bugzilla.gnome.org/show_bug.cgi?id=671656
This assignment was shadowed by the giant switch above. Since the
switch has a comment or two explaining the logic inside of it,
keep that instead of the assignment.
Since the invoker for navigate_focus has an extra parameter, annotations
from the invoker aren't applied on the vfunc itself. Fix that by annotating
the vfunc separately.
This allows us to do directional keyboard navigation when there's no
actor inside the horizontal or vertical strip extending from the
origin actor but there are other actors to the sides of that strip
that could still be used as targets even if that means the focus would
move diagonally.
https://bugzilla.gnome.org/show_bug.cgi?id=663901
For arrow keys navigation, when moving from a widget which isn't a
descendant of the widget we are going to, it's unexpected that focus
moves to the target's first descendant instead of the closest to the
source widget.
This requires us to use absolute coordinates to compare widgets since
we no longer have the guarantee that the widgets we are comparing are
siblings.
https://bugzilla.gnome.org/show_bug.cgi?id=663901
When porting from st_container_get_children_list to this code, I accidentally
broke StTable by a copy/paste error. This broke notifications that updated,
leaving them with what they think were 0 columns and 0 rows.
https://bugzilla.gnome.org/show_bug.cgi?id=670640
The very similar clutter_actor_allocate_align_fill is close enough
that this is just needless duplication. Additionally, allocate_fill
already inverts the align if the text direction is RTL, so we don't
need to do that here.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Now that StWidget is a group of sorts, it needs to account for its children
in its paint volume. Unfortunately, this causes havoc for StBoxLayout, so it
needs fixing - it's unknown why it worked when chaining up to near-identical
code in StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
The get_focus_chain() implementation in StWidget just returns all
children, it should filter for visible children instead. This
breaks keyboard navigation in various places since commit 72dad591
removed the correct implementation in StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670904
Now that ClutterActor has a ClutterContainer implementation, we
can start removing StContainer. To help make this a bit more
understandable, instead of converting everything at once, make
StContainer a compatible API wrapper around the ClutterActor
implementation, and then we'll remove those wrappers in later
commits.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Since an StWidget now has children, it needs to allocate those children
properly. Defer to the currently installed layout manager, like Clutter
does.
Now that we have something that allocates children in St, to prevent
double allocations, we use clutter_actor_set_allocation rather than
chaining up to StWidget::allocate.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Now that StWidget is concrete and instantiable, we need to do something
other than return an adjusted 0 for width and height. Just chain up
to ClutterActor's default implementation, which uses the layout manager.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Since we want to paint children by default in StWidget, we need to
provide a way for custom subclasses to paint their CSS backgrounds
without painting children... introducing st_widget_paint_background.
Additionally, remove any custom paint/pick handlers added by subclasses
of StWidget that just painted their children. This will cause double
painting if left alone.
This also removes the hacky things that some subclasses of StBin did
to prevent their one child to be painted by StBin.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Clutter now provides two new properties on ClutterActor - first-child
and last-child, so we have notifiers on when they change. Unfortunately,
it still doesn't help us too much - we need to keep track of the previous
values of the properties so we can remove their pseudoclasses.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
We can't get rid of the implementations in StContainer just yet,
as StContainer still keeps its own child list. But this should
lower the amount of code that has to be moved around when we
remove StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
clutter_container_foreach is deprecated, so let's replace that
with some ClutterActorIter usage. Additionally, remove the checks
for ClutterContainer, as all ClutterActors are now ClutterContainers.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
The handle was a child of the trough, but it was allocated and painted
like it was a child of the bar. This will wreak havoc when we port over
to the new Clutter API, so let's just make it a child of the bar.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Clutter, since version 1.8, does The Right Thing™ inside the default
implementation of ClutterActor::map and ClutterActor::unmap, even for
non-container actors: it will iterate over the list of children and
map, or unmap, each one of them, respectively.
This means that the requirement to override map and unmap for composite
actors to map and unmap the internal children has been dropped.
https://bugzilla.gnome.org/show_bug.cgi?id=669239
Since our implementation of background-size is now CSS-compliant, we
do not need this subtexture hack that clips a "leak". The comment here
is also incorrect.
https://bugzilla.gnome.org/show_bug.cgi?id=633462
It seems that accidentally, two variables were swapped in one code path
of the background-size implementation, causing interesting but wrong
images for some elements.
https://bugzilla.gnome.org/show_bug.cgi?id=633462
A new texture has undefined contents - when we're creating a shadow,
we need to clear the contents of the texture before drawing the border

Implement the background-size CSS property, specified by the CSS
Backgrounds and Borders Module Level 3, including the keywords

grid_width and grid_height were inverted, which caused a crash
in GdkPixbuf code. This was never noticed because the animation

For some reason, the texture cache decides to make a request and then look up
an icon in the icon theme. If it's valid, it just returns, fine, but if it
doesn't add the icon, it tries to undo the request, leaking an
AsyncTextureLoadData that isn't freed in the process.
https://bugzilla.gnome.org/show_bug.cgi?id=660968
Rather than have five or six structs allocated duplicating data,
just keep one and simplify the code considerably.
Again, part of my ongoing quest to merge St and Mx.
https://bugzilla.gnome.org/show_bug.cgi?id=660968
If we add a 0-sized actor with a border-radius, we will crash as we try to
allocate a 0-sized texture in Cogl. Bail out early instead of doing that.
https://bugzilla.gnome.org/show_bug.cgi?id=661617
The translate coordinates are calculated as the offset after the scale, so it
needs to be applied after the scale as well. This fixes random centering issues
in the UI.
https://bugzilla.gnome.org/show_bug.cgi?id=660674
For GIcons we use g_icon_to_string() in the key, but the function
will return NULL if the icon cannot be serialized. As a result,
all non-serializable GIcons of the same size end up with the same
cache key - an example for this are contacts with avatars, which
currently all end up with the same image.
To fix, opt out of caching for GIcons which cannot be serialized.
https://bugzilla.gnome.org/show_bug.cgi?id=660585
Setting up the framebuffers for transitions may fail, in which case
the material used for drawing is left uninitialized, so trying to
access it results in a crash.
Instead bail out in this case, which means that we won't paint
anything during the transition - still, drawing errors are better
than crashes ...
https://bugzilla.gnome.org/show_bug.cgi?id=659676
Instead of doing complex computations in the shader just pass in the correct
fade area (taking padding, scrollbars and rtl into account) and just work
with that in the shader.
That fixes a bug where we would fade the scrollbar when padding is present.
https://bugzilla.gnome.org/show_bug.cgi?id=659159
StAdjustment has some non-functional and unused animation vestiges
like the "elastic" property, st_adjustment_interpolate() and
st_adjustment_clamp().
This commit vacuums that stuff up so it doesn't tempt anyone into
trying to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
If a container is not clip-to-allocation, then its get_paint_volume()
needs to include the paint volumes of all of its children, since they
(or their children) may paint outside the container's allocation.
Also, if the superclass get_paint_volume() returns FALSE, then the
subclass should return FALSE too.
https://bugzilla.gnome.org/show_bug.cgi?id=655812
Clutter 1.7.x introduced CLUTTER_CAIRO_FORMAT_ARGB32: which can be used when
sharing textures/data with cairo without having to do check the
byte order and choose the appropriate format by hand.
https://bugzilla.gnome.org/show_bug.cgi?id=654577
The cogl path pads the corners out to the maximum corner radius to make the
math and painting logic easier. Unfortunately, when the radius exceeds the
actor's halfsize, the padding ends up interfering with other corners, creating
a big mess of rendering errors.
It'd be extremely complicated to fix this properly in the Cogl code,
so take the Cairo fallback.
https://bugzilla.gnome.org/show_bug.cgi?id=649513
Currently, any cases of overlapping corners were just ignored and rendered incorrectly.
Implement the corner overlap algorithm as specified by the W3C to fix this.

Only skip the areas of the scrollbars when they are invisible

Using the list of stylesheets loaded with st_theme_load_stylesheet(),
one can build an StTheme that is completely identical to the previous
one, except for one property (application-stylesheet).
This allows rt and the user-theme extension to work while respecting
the theming of other extensions.
https://bugzilla.gnome.org/show_bug.cgi?id=650971
Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of
0 disables the effect.
This new CSS approach replaces the current programmatic toggle of
the 'vfade' property. A new CSS style class name 'vfade' is used as
a replacement for the old property.

Remove a workaround for clutter_actor_get_transformed_position() not
working inside paint(), and remove a comment about
ClutterText::position not being properly notified, since it is now.
(However, it doesn't seem worth it to rewrite the code to use
notification, since that would actually end up being more complicated
than the current solution.)
https://bugzilla.gnome.org/show_bug.cgi?id=648758
StScrollBar was tracking whether or not it currently had a valid

This property represents that the widget is being labelled by an
actor. The name is label-actor to avoid problems with the current
StButton:label and StTooltip:label
If a caller sets an StLabel's text to what it already is (as, eg, the
clock menu does), do nothing. Unless the label is editable, in which
case, setting the text has a visible side effect (dropping the
selection), so we don't optimize that out.

Some functions in StTextureCache enforce square ClutterTextures,

If, for example, the stage is divided into multiple monitors, we
might want to constrain tooltips so they don't cross monitor boundaries.
Add a function to set a per-stage callback to constrain tooltips.

Use ClutterContainer functions for adding the tooltip instead of
calling clutter_actor_set_parent behind the stage's back, and do
it inside st_widget_show_tooltip (which is a normal method) instead
of overriding st_tooltip_show, which is a vfunc and it is called
internally by Clutter, therefore it is limited in what it can safely
do.
Also, instead of positioning the tooltip with clutter_actor_set_position,
modify the anchor point when the associated widget moves, so that
only a redraw is queued.

Inside the Shell, all the UI (including chrome, the overview, and
the actual windows) is not a child of the stage but of a special

StButton was mistakenly considering any Space/Enter KEY_RELEASE to be
a click, when in fact it should only count as a click if it also got
the corresponding KEY_PRESS as well. This meant that when typing in a
chat notification, any Space/Enter keypress would dismiss the
notification, since the StEntry would take the PRESS event but ignore
the RELEASE, allowing it to propagate to the notification itself,
which would treat it as a click.
