All adjustment setter functions take good care of avoiding emission of
notify:: when it's not needed. The set_property() implementation already
calls into the setter functions, so mark the properties as EXPLICITY_NOTIFY
in order to optimize notify:: emission away through g_object_set (rather
common from JS code).
The actor allocation doesn't change per-se, but apply_transform()
will practically transform it. In order to have the paint volume
update accordingly, queue a relayout.
The default get_paint_volume() implementation will do the union
of children, and the child ClutterText paint volume may expand
beyond StEntry size when text overflows.
We actually want all content to be clipped to the StEntry, so
implement get_paint_volume() and tell it so.
And constrain it in StScrollView instead (instead of falling back to an
infinite paint volume, as the actor as paint/pick impls, but no
corresponding get_paint_volume one).
Fixes artifacts with the AppView (and possibly other places) when paint
volumes are aggressively cached.
The default keyed_surface is meant to handle CoglTextures thus we can't
add cairo surfaces to it, as the DestroyNotify function won't handle them.
Then the quicker way is to just add another Hash table for handling
such types of textures, with proper destroy function.
This might cause a crash when cleaning up the cache as the hash table has
cogl_object_unref as DestroyNotify function but that assumes that
the passed object is a valid CoglObject.
Fixes: #210
The instance is owned by the actor (being its child), and thus when the
disposal happens for the parent the text is disposed too, thus it's just
safer to nullify its reference so that we won't try to access to invalid
objects later, and this might be the case since the JS objects could be kept
around until they aren't finalized.

Call _st_set_text_from_style() when updating the entry's style, so
that CSS style properties such as text-decoration or letter-spacing
are applied over the internal ClutterText instance.
If an actor is pending a relayout when get_allocation_box() is called,
the method forces an allocation update. In case of StWidget, this might
then result in a style update and a consecutive invalidation of the
shadow spec.
A helper method that invalidates one of its parameters as a side effect
(and by extension its return value as well) is most unexpected, so cur-
rently _st_create_shadow_pipeline_from_actor() poses an easy trap to
callers to run into.
Remove that trap by calling get_size()/get_position() instead, which
don't have the unintended side effect - it is still a good idea to fix
callers who were running into this to not waste resources on creating
shadows that are invalidated before the next paint, but throwing un-
defined behavior at them is harsh ...
https://bugzilla.gnome.org/show_bug.cgi?id=788908
The st_button_release() call wouldn't happen because StButton does not
set priv->button_mask on touch events. And if we make it called, we can't
try to unset the device grab at the end of the function, as device/sequence
are unset earlier on.
When creating a shadow for a ClutterTexture, we currently use the
underlying CoglTexture directly instead of rendering the actor to
an offscreen buffer. This assumes that the CoglTexture is directly
suitable as shadow source, which isn't necessarily the case - it
may have a very different size than what is shown and scaled up or
down by the hardware. In that case we end up with a scaled shadow
texture as well, which messes up the desired blur effect - the
result will be too light when scaling up, or too sharp when scaling
down. To fix this, only take the shortcut when a ClutterTexture's
underlying texture has the correct size and fall back to offscreen
rendering otherwise.

Unlike pango_font_description_from_string(),
pango_font_description_set_family() requires a already properly
formatted font family string. The proper format is a comma seperated
list of font families, but we generated a "comma space" separated list.
Passing a incorrectly formatted font family string to pango seems to
cause wierd issues, where the wrong font is sometimes selected.
For example, this fixes a font selection issue on zh_TW.UTF-8 locale for
chinese characters, where previously the "Droid Sans" font was selected
instead of "Source Han Sans TW" even though fontconfig had placed
"Source Han Sans TW" before "Droid Sans".

Compiling the generated source for each consumer of the dependency
means we end up trying to register the enum types multiple times,
resulting in a fatal failure on startup. Luckily code outside libst
itself only depends on the header, which doesn't cause those issues.
st_built_sources contains the source and header generated by mkenums,
not any other generated sources. Clarify that in the name, as we are
about to use source and header separately.
We cannot rely on any build order, except the one we specify ourselves.
St depends on various generated files; other targets depend on those
files existing, so they can be included. There is no direct relationship
between targets and files, unless we declare a dependency, using the
Meson declare_dependency() constructor — which allows us to replace the
various `link_with` directives with the more appropriate `dependencies`
one, and also allows us to specify sources that must exist by the time
we build those targets.
In parallel builds we may end up with st-enum-types.c being built inside
separate targets outside of src/st which may not have the ST_COMPILATION
pre-processor symbol defined. For this reason, we need to define it
ourselves in the source file, before including other headers, to avoid
the single-include guard.
Meson is on track to replace autotools as the build system of choice,
so support it in addition to autotools. If all goes well, we'll
eventually be able to drop the latter ...

There's no need to explicitly destroy the ClutterText actor inside the

Since commit 48a54e8ac4, paint() has an explicit framebuffer parameter,
however a couple of submethods are still using the draw framebuffer,
which breaks when rendering to an offscreen buffer.
If we are trying to render a shadow at a size that is very large in one
direction, but small in the other direction (so that we don't 9-slice
the texture), then allocating the backing texture for the offscreen
buffer may fail due to texture-size limits. Don't crash in that case.

Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).
They are unused, as we don't use them ourselves and the class is not
exposed to introspection. Drop them to allow defining the type as final
in an upcoming commit.
There is nothing preventing callers from replacing the internal
layout manager, and as long as the replacement is a (or derives

losing a bit of automatic property mapping - and the latter is

Since commit 4f1f226828 we only consider buttons clicked when the
release event had a corresponding press event. However as we use
the hover state to check whether a release event actually occurred
on the button, we dismiss any clicks in cases where we missed the
enter event - most likely due to some other actor holding a grab.
Instead, check whether the button contains the event's source, which
should be less error-prone.

Which, coupled with fatal warnings, breaks the Shell build.
We currently don't have any code either in gnome-shell or

It's implemented similar to the padding property, but instead of taking
into account the margin values at drawing time in node-drawing, we set
the clutter actor margins in StWidget when the style is computed.
In the case that a CSS margin is not specified, we don't to set a value
of 0 to the clutter actor margin. In this manner it allows to use
Clutter margin values set in the code. However, the margins that are set
both in the code and in the CSS on the same side, the result is
unpredictable.
We avoid to set the clutter actor margin values to 0 if there's no CSS
margin values defined, so we still allow clutter actors to use margin
set in the code.

clutter_device_manager_get_core_device calls XIGetClientPointer, which

Replace this with get_device with the ID of the VCP/VCK, since mutter

Sorting actors by the distance in the axis of movement first and against
the axis otherwise means that if we have a situation like:
A F
B
where "F" is the focused actor, and it slightly overlaps with B vertically,

fade into two uniforms and compute the "should we fade the edges"
boolean once for every direction (when setting the uniforms) instead
of for every single fragment twice.
This reduces the number of uniforms as well as the the number of instructions
which are limited on older hardware. It should also be more efficent.

- it is the only actor we have that implements the scrollable interface
- it conveniently exposes its spacing property in CSS
- last but not least, it is used all over the place
So do the next best thing and make our implementation use the

Commit cfecd063c9 changed the allocation logic to not allocate
scrollbars when the *_visible booleans are false. This breaks the

when they are not supposed to be visible, so not allocating them
and thus leaving them in a "needs allocation" state just causes problems.

them anyway).

When the St theme is changed, the StThemeContext unrefs all the theme
nodes cached in it's internal hash table, then emits a signal to
notify all theme nodes that the current theme has changed.
The problem is that the first StWidget to catch a theme changed signal
will trigger a "style-changed" signal catched by its children first.
So the theme changed signal can't be processed properly to cleanup
StThemeNodePaintState before recomputing the theme.

Currently the box-shadow is rendering is done like this :
The first time we want to render a node that requires a box-shadow, St
creates an cogl offscreen surface of the size of the allocation and
renders the box into this offscreen buffer using modulation on the
alpha channel, this buffer is then blurred according to the CSS
parameters.
The problem with this method is that every time an StWidget is
resized, its box-shadow offscreen buffer has to be resized and
therefore rendered and blurred.
This patches propose an optimization for this use case by rendering
the box-shadow only once but at a size that is independent of the
StWidget's size. Then every time we need to paint this box-shadow, we
just render this offscreen buffer using a 9-slices.
This method only works when the allocation of the widget is bigger
than the minimum shadow size on which we can apply a 9-slices, that is
given my the radius of the corners. If the allocation is smaller than
this minimum size, we then fallback to the fully render/blur the
shadow (like before this patch).

While it is obviously still an error to call get_theme_node() on a

there'll always be code paths where we can hit this case and make

The shadows are currently rendered by painting the actor we want to
apply shadow on, in an offscreen buffer. The problem is that when this
actor has an allocation padding (ie allocation that isn't at 0x0
relatively to its parent), this padding is added within the offscreen
buffer and as a result the shadow rendering is truncated because the
offscreen buffer size is the size of the allocation box, not the
allocation box + padding.
This patch reposition the actor at 0x0 with rendering it by changing
the initial transformation matrix when rendering the actor offscreen.
