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

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.

Clutter 1.7.x introduced CLUTTER_CAIRO_FORMAT_ARGB32: which can be used when

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.

Currently, any cases of overlapping corners were just ignored and rendered incorrectly.

Using the list of stylesheets loaded with st_theme_load_stylesheet(),
one can build an StTheme that is completely identical to the previous

Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of

This new CSS approach replaces the current programmatic toggle of

a replacement for the old property.

Remove a workaround for clutter_actor_get_transformed_position() not

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

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

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.

When we compare the boxes for two actors, they may appear to overlap

clutter_init() fails under normal circumstances like

The number instructions in a shader is limited to 64 on r300 hardware,
the fade shader in StScrollViewFade was ending up using 97 instructions
which is way over the limit.
So refactor the shader to use less instructions by precomputing as many

ends up using 34 instructions which is well within the hardware limits.

When navigating from a non-immediate descendant of a container, we
were attempting to use clutter_actor_get_transformed_position() to get

the intermediate container when navigating back.

g_themed_icon_new_with_default_fallbacks() does not do what we want
with symbolic icons; if the user's icon theme is not "gnome", then it
will end up preferring a non-symbolic icon from the higher-level theme
over a symbolic icon from gnome-icon-theme-symbolic.
If the shell requests a symbolic icon, and there is only a
non-symbolic icon available, that should be considered a programmer
error, just like requesting a non-existent icon name. So change the
code to only look up "-symbolic" names when drawing an
ST_ICON_SYMBOLIC icon.

PopupMenuManager was pretending that it knew nothing about the menu's
sourceActors, while also trying to handle keynav between them. This

At times, RTL locales require different CSS, so always create theme

For historical reasons, StEntry always did hover tracking when you had
visible hint_text, even if track_hover was FALSE. Remove that special
case, and make entries track hover just like all other widgets do.
If we actually needed to distinguish hovered-with-hint-text from
hovered-without-hint-text (which, at the moment, we don't), we could
do that by setting separate CSS for :hover and :hover:indeterminate.

If we aren't going to fill the content area of the node with a solid

This reverts commit b4ec342d06.
The alpha > 0 checks should actually be alpha < 255 for the commit to

since we need to preserve the translucency in translucent gradients,
not block it with a solid color fill.
https://bugzilla.gnome.org/show_bug.cgi?id=640465
If a background gradient isn't fully opaque, then we need to first
fill in the background color so the border color doesn't leak into
the interior.
https://bugzilla.gnome.org/show_bug.cgi?id=640465
We need to be careful to ignore any preexisting color information
in the interior of the node when filling it with the background color,
since the border color may have leaked into the interior and the
background color may be translucent.

The material of prerendered backgrounds is now painted in the
rectangle determined by st_theme_node_get_paint_box(). As the
ClutterActorBox returned from that function includes the space
needed to draw the box shadow, the background ends up occluding
the shadow.
As the box shadow is not part of the background, factor out a new
helper function which excludes the box shadow, and use it to
prerender and place the background material.

1. Both functions leaked the nodes in priv->children
2. st_container_remove_all wasn't properly updating first_child and last_child

the caller can simply use clutter_container_remove().

Loading a pixbuf in a way that cairo can use it is a

A lot of the border drawing logic in st_theme_node_render_gradient is

When drawing the background image shadow, we need to clip it
to the node's background color, gradient, or borders if present.
If the background color is transparent, and there aren't any
borders, then we don't clip the shadow since there is nothing
to confine it.
https://bugzilla.gnome.org/show_bug.cgi?id=636976
The border_texture (and border_material) variable is being
overloaded for two purposes: it's used as a source
to 9-slice the border from, and it's used as place to prerender
the background and border together for gradients.
While we only do one or the other for any given node, the two cases
are distinct, and should use distinct variables for readability.
https://bugzilla.gnome.org/show_bug.cgi?id=636976
Currently, "-st-shadow" can mean one of three very
different things:
1) shadow based on alpha of the background image
2) shadow the "border box" of the node
3) shadow applied to the content of a StIcon
It isn't well defined which of the above 3 cases
-st-shadow will mean for any given node, however.
This commit splits the property into three
different properties, "box-shadow",
"-st-background-image-shadow", and "icon-shadow"
to make it all very explicit.

StWidget reports a paint volume large enough to paint the current
theme node. As CSS transitions also paint the previous theme node,
the reported paint volume may be incorrect, resulting in screen

large enough to paint both theme nodes, and use it to report the correct
paint volume during transitions.

Right now is just redefine atk_object_get_name.
If someone wonders why not implement AtkText interface, or expose the
internal ClutterText, here a extract from AtkText doc:
"AtkText should be implemented by AtkObjects on behalf of widgets that
have text content which is either attributed or otherwise
non-trivial. AtkObjects whose text content is simple, unattributed,
and very brief may expose that content via atk_object_get_name
instead;"
StLabel is attributed, but is still simple and brief. In the same way
the atk_object_get_name redefinition is required, so this patch is the
first step. We can implement AtkText in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=626658
It includes:
* Expose a proper focusable state, instead of the default one from
cally, using StWidget::can_focus, and also notifying the state change
* Management of the selected stated, using the current pseudo_class.
* Defines a new virtual method on StWidget: get_accessible_type. In
this way it is not required to reimplement get_accessible just for
a accessible type change. get_accessible is reimplemented using this.
You can see that as a substitute of the atk object factory

Instead of converting a CSS-specified length to an integer by truncation,
round. This means that sizes specified by converting a pixel value into
non-px terms will work reliably instead of potentially being off-by-one.
We weren't freeing the whole pixbuf, nor were we the GList of
subpixbufs. Plug both of these leaks in the error handling path
and in the default case.
All of the unreffing/cleanup should happen in the GDestroyNotify
for the result, not some in the handler.
https://bugzilla.gnome.org/show_bug.cgi?id=636489
While non-uniform border widths were parsed correctly, an arbitrary
side's width was picked when painting, so that each border ended up
with the same width and the widths specified in CSS were ignored.
At least for sides between non-rounded corners, using a different
border width can be reasonable, for instance at screen edges.
Different border widths around rounded corners are kind of crack,
but then it would be lame not to support it ...
https://bugzilla.gnome.org/show_bug.cgi?id=607500
For gradient backgrounds, borders were implemented by filling the
background shape with the border color first, and then scaling down
the path to draw the background.
The result is not correct[0], which is especially visible if the border
width is greater than the border radius - so instead of scaling down
the original path, use a separate path for the background.
The result is consistent with the borders we draw for non-gradient
backgrounds, and much closer to the correct standard behavior.

non-absolute paths specified as url()'s in

This commit ensures that we don't try to use the stylesheet associated

This commit doesn't try to handle relative paths in inline styles.
It only prevents crashes when absolute paths are used.

When scrolled, st_box_layout_apply_transform() includes the scroll
offset and affects paint volumes. This is right for our children, but
our paint volume is determined by our allocation and borders and
doesn't scroll, so we need to reverse-compensate, the same as we do
when painting.
https://bugzilla.gnome.org/show_bug.cgi?id=630932
In order to take advantage of clipped redraws (only redraw the
parts that actually changed), we have to inform clutter about
our paint_volume by implementing the get_paint_volume virtual
method.
As this feature had been added in in clutter 1.5.x we now require
that.

Connect to the "changed" signal on the default icon theme, and
when it triggers:
- Evict all cached looked up icons from the StTextureCache
- Fake a style change on all StThemeContext; this will result
in StIcon looking up icons again.
https://bugzilla.gnome.org/show_bug.cgi?id=633866
It is not referencing them when adding, and also it is connecting
to the "destroy" signal, emitted on dispose, so there is no risk
of storing finalized objects.
https://bugzilla.gnome.org/show_bug.cgi?id=634781
We were always drawing the border and background of each
StThemeNode, even if they were transparent. The simple
optimization of checking the alpha provides a significant
performance boost (in a quick test, it increased the
overviewFpsSubsequent metric in the core performance test
from 28fps to 35fps).
https://bugzilla.gnome.org/show_bug.cgi?id=634752
Now that we're using St.Icon in the Javascript, there is no reason
to have separate st_texture_cache_load_icon_name() and
st_texture_cache_load_icon_name_for_theme(), instead just add
the StThemeNode argument to st_texture_cache_load_icon_name().
https://bugzilla.gnome.org/show_bug.cgi?id=633866
Use st_texture_cache_load_icon_name_for_theme() so that we get the
right colors for symbolic icons. The code refactoring to achieve this
also avoids constantly starting a new icon load each time we set
a property on initialization ... the icon is loaded only after we
have a #StThemeNode assigned.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Sometimes it's useful to get the theme node if there is one and do
nothing and wait for the ::style-changed signal if there is no theme
node. Add st_widget_peek_theme_node() that just gets the current
theme node if available. The caller must handle a %NULL return.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Add st_texture_cache_load_icon_name_for_theme() which, when loading a
symbolic icon, gets a #StIconColors from the theme node and uses that
to colorize the icon.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
A new StIconColors object is used to efficiently track the colors
we need to colorize a symbolic icon.
st_theme_node_compute_icon_colors() is added to compute the
StIconColors for a theme node. (Refcounting of StIconColors means
that we'll typically share the colors object of the parent node.)
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Scaling up icons from the loaded size to a larger size is uniformly
ugly and results in a long series of "fuzzy icon" bugs. It's better
to just load at the specified size and center. (Centering can be
overridden by packing not-fill in the parent container.)
https://bugzilla.gnome.org/show_bug.cgi?id=633865
We don't want the layout to change when we say, change from
battery-full to battery-full-charging, so we should request a square
based on the icon size unconditionally and not try to adapt to the
size of the texture we loaded. This also means that our layout is
independent of the loaded texure which, if we switch away from
using a ClutterActor child will allow us not queue a relayout when
the icon finishes loading.

Make StIcon compile and work in St.
Changes:
* ::icon-type and st_icon_set_icon_type are added to allow
specifying SYMBOLIC/FULLCOLOR for an icon.
* Ability to set the icon name from the theme is removed; it
wouldn't easily fit into our framework and two levels of
abstraction between code and image doesn't seem that useful.
* size CSS property is renamed from x-st-icon-size to icon-size
to correspond to what we are doing elsewhere.
* CSS and property based icon sizing are cleanly layered - if
you set the icon-size property, the CSS size is ignored.
* Add a simple JS test of StIcon.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
StIconType will be used by a new StIcon class, so move it to the
header file of common enumerations. Including st-types.h which had
the St single-include check revealed that st-texture-cache.h didn't
have that check and several places were including that directly.
Fix that up.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
The ability to set a "content image" on an icon relies on the ability
to have custom theme properties of a "border image" (9-slice) type.
We don't have this, and the capability of a bordered image specified
by the theme can be achieved more naturally with standard CSS facilities.

We weren't properly nulling out the vadjustment variable in dispose()
which meant in the case of explicit-destroy followed some time later
by garbage collection and disposing the actor again we would crash.
Use StWidget:track-hover rather than doing it ourselves. Don't assume
that hover is always TRUE after an enter_event or FALSE after a
leave_event, since we have a pointer grab and will be getting other
actors' events.
Don't ungrab the pointer when it leaves the button, since that
destroys the whole point of getting a grab in the first place.
Only consider the button to have been clicked when it has both grab
(meaning the mouse was pressed over the button) and hover (meaning the
mouse was released over the button).
Also remove the virtual pressed/released methods, which weren't being

In d66e7dd49 I got confused between border_texture and
background_texture. The background_texture was being created as normal
but in the one place that it gets drawn I accidentally made it use the
border_material instead. This patch makes it create a
background_material similar to the border_material and uses it to
paint.
A few places in st-theme-node-drawing create one-shot material, paint
with it and then free it. This is suboptimal with current Cogl because
it will end up compiling an ARBfp program just for that single paint
and then it will throw it away when the material is destroyed.
There is a new function in st-private.c called
_st_create_texture_material. This creates a simple material for a
texture based on a common parent material that points to a dummy
texture. Any materials created with this function are likely to be
able to share the same program unless the material is further modified
to contain a different number of layers. It would be possible to use
cogl_set_source_texture for this instead except that it's not possible
to modify the material's color in that case so we couldn't render the
texture with opacity.
The corner textures are now stored as a handle to a material that
references the texture rather than storing the texure directly. There
is also a separate border_material member which always points to
border_texture as the only layer.

Although within St itself there are situations where the semantics of
these functions (return TRUE or FALSE and return the actual value in
an out parameter) is useful, it's mostly just annoying at the
application level, where you generally know that the CSS property is
going to specified, and there is no especially sane fallback if it's
not.
So rename the current methods to lookup_color, lookup_double, and
lookup_length, and add new get_color, get_double, and get_length
methods that don't take an "inherit" parameter, and return their
values directly. (Well, except for get_color, due to the lack of (out
caller-allocates) in gjs.)
And update the code to use either the old or new methods as appropriate.

st-theme stores some loaded stylesheets in a custom
stylesheets list. When removing items from this list
it unrefs them, but when adding items to the list it
neglects to ref them. This means that under certain
circumstances the list will contain items that have
already been freed.
https://bugzilla.gnome.org/show_bug.cgi?id=632477
StDrawingArea uses the member variable needs_repaint to keep track
of whether it needs repainting. The variable is set to TRUE correctly,
e.g. on allocation or style changes - alas, it is never set to FALSE,
resulting in the area being repainted continuously.
https://bugzilla.gnome.org/show_bug.cgi?id=632197
Non-uniform border-radii are already supported when using a gradient
background, this patch adds support for solid colors as well.
The currently applied technique of using corner textures and filling
the remaining area with rectangles is extended, so that each corner is
padded with rectangles to the size of the largest corner.
Add border-radius.js to test cases, to test non-uniform border-radii
with both solid color and gradient backgrounds.
https://bugzilla.gnome.org/show_bug.cgi?id=631091
Icons can be loaded as St.Icon.SYMBOLIC, FULLCOLOR, APPLICATION or
DOCUMENT. The first will look for a symbolic equivalent, the second
looks for a full-color version (and does fallback, eg, from
"drive-harddisk-usb" to "drive-harddisk"). APPLICATION and DOCUMENT do
full-color icons without fallback (as specified by the icon spec).
And update various callers to use the right flags.
Based on a patch from Matt Novenstern.

Switch to using the layer combine constant rather than the material
primary color for representing the opacity of the material; this
avoids triggering a Cogl bug where changing the primary color corrupts
the layer state.

* Use --warn-all, --warn-error
* Fix various broken gtk-doc
* Drop unused shell_get_event_related
* For header defines, we currently require them to end in _H to be skipped
* Drop the no-longer-necessary fix-meta-rectangle.py hack
* Move to the convention of using -private.h for headers that are,
well, private.
* Add shell-wm-private.h
Move shadow helper functions from st-theme-node-drawing to st-private
to make them available to widgets which want to add shadows to internal
actors.
Also add a new helper function for creating the shadow material from a
ClutterActor.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
Reorganize the existing code which parses the -st-shadow property
to allow parsing different shadow properties and add support for
the text-shadow property.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
If a shadow property is inherited from a parent, multiple StThemeNodes
share a common StShadow. It would be possible to use st_shadow_copy()
for this purpose, but proper reference counting is nicer.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
Add basic support for background-position, which only supports absolute
values.
Also don't require an unit to be specified for 0 (because the unit does not
really matter here 0 is 0 regardless of the unit).
https://bugzilla.gnome.org/show_bug.cgi?id=624375
Add st_theme_node_paint_equal() and use that to do two things:
1) Avoid animating transitions where nothing changes.
2) Copy cached painting state from the old theme node to the new
theme node.
https://bugzilla.gnome.org/show_bug.cgi?id=627083
Creating an FBO may be expensive, so we should avoid the operation
if possible. When transitioning between theme nodes, the widget's
opacity is used to paint to the offscreen textures which are blended
together - this means that the textures have to be recreated each time
the widget's opacity changes. It is much more effective to paint the
textures at full opacity and respect the widget's paint opacity when
blending the textures together.
https://bugzilla.gnome.org/show_bug.cgi?id=627085
The function has been upstreamed as clutter_actor_contains() - with
the switch to clutter-1.4 it is now available to the Shell, so it
is no longer necessary to keep a copy in-tree.
https://bugzilla.gnome.org/show_bug.cgi?id=626512
Add support for the CSS :first-child and :last-child properties to
StContainer, and thus to all containers in St and ShellGenericContainer.
The internal ordering of the container's children is used to determine
the child to which to attach the pseudo class, not the children's
positions. This means that containers where positions can differ from
the ordering (ShellGenericContainer / StGroup) may behave unexpectedly,
so some caution is required.
https://bugzilla.gnome.org/show_bug.cgi?id=625316
There's an assertion in calculate_gaussian_kernel() to avoid a division
by zero - due to an unnecessary cast from float to int this assertion
is triggered incorrectly for small (but non-zero) values, e.g. a blur
radius of 1px.
"text-align" allows setting the alignment of text, with respect to
other lines and allocated space, without requiring a reference to
the ClutterText (which is private for most widgets).
If not specified, all text is left-aligned.
https://bugzilla.gnome.org/show_bug.cgi?id=622447
It has probably crossed the line to evil by a mile or so, but here
it is: a Tweener.slowDownFactor replacement used by all animations
without exception.
While at it, update Tweener to use the new setTimeScale() upstream
function instead of adjusting the timeline directly.
https://bugzilla.gnome.org/show_bug.cgi?id=622249
This function reads a single image file which contains multiple
images internally.
The image file will be divided using @grid_width and @grid_height;
note that the dimensions of the image loaded from @path
should be a multiple of the specified grid dimensions.
https://bugzilla.gnome.org/show_bug.cgi?id=598349
The framebuffer setup code can fail, e.g. when the texture used as
color buffer has a height/width of 0. In that case, the call to
cogl_pop_framebuffer() will crash the shell trigger an assert. Add
error checking to fail gracefully.
Add _st_actor_contains() in st-private for use within St, and
monkey-patch in a Clutter.Actor.contains() for use by javascript, and
then replace all the duplicate implementations with one or the other
of those.
https://bugzilla.gnome.org/show_bug.cgi?id=621197
Our behavior of reversing the animation when the widget's style
changes back to the previous one is sound. On the other hand, when
there's a change to a new style while a transition is active, we
simply cancel the ongoing transition. Updating the transition
correctly so that the new one starts from an intermediate state
is hard.
Nevertheless, if the style changes before any time of the transition
has elapsed, we should do better than the current behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=621140
The current code only sets up / updates transitions when the new
node's transition-duration is non-zero. It should cancel an
existing transition if the duration is 0.
It is sometimes desirable to fade smoothly between two styles
instead of changing it abruptly.
Add transitions controlled by the transition-duration CSS property.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
StThemeNodes may have properties - namely shadows - which paint
outside an actor's allocation. This is not a problem unless drawing
is redirected to an offscreen buffer, in which case the actually
painted size is needed in advance when setting up the buffer.
Add a convenience method to calculate an allocation large enough to
paint the node.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
Add st_theme_node_equal() - two nodes are considered equal iff they
refer to identical elements, so e.g. .example and .example:hover are
not equal, even if no .example:hover rule exists in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
When hovering over the entry's ClutterText, the entry itself
currently receives a leave event and updates the hover state.
Apply the same logic as StWidget itself to treat children as
part of the entry.
https://bugzilla.gnome.org/show_bug.cgi?id=620381
Currently shadows disregard the overall opacity, so e.g. setting
an ancestor's opacity does not effect the shadow. Fix this by
deferring the setting of the shadow's color until it is painted.
Also move duplicated drawing code from st_theme_node_paint() into
its own function.
https://bugzilla.gnome.org/show_bug.cgi?id=619083
Currently the size of an StGroup depends exclusively on the group's
children - it should be possible to override this behaviour with
fixed values in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=613907
I have no idea why there existed code that if we saw e.g. min-width
without a width, we assigned min-width to ->width, thus effectively
treating it as a maximum.
Just delete that bit.
https://bugzilla.gnome.org/show_bug.cgi?id=618482
Passing an explicit width in the wfh case or a height in the hfw case
messes up the request caching, and confuses actors that assume they
won't be called with an explicit width/height unless they're being
allocated along the other axis.
https://bugzilla.gnome.org/show_bug.cgi?id=618295
Add StContainer, which implements the ClutterContainer interface based
on the container methods in st-private and make the existing containers
subclass it.
https://bugzilla.gnome.org/show_bug.cgi?id=613907
The StTable code only supports height-for-width. When called in
width-for-height sizing mode, instead of treating the -1 flag
value of 'for_width' as a real width, and requesting all the
children at 1 pixel wide, use the natural width of the table
as the width for determing the height.
Since we can't rewrap in width-for-height mode, we then report
the natural width also as the minimum width of the table.
https://bugzilla.gnome.org/show_bug.cgi?id=618104
As StEntry handles hover differently depending on whether it is
activated or not, the generic hover support in StWidget is
insufficient. Nevertheless it makes sense to set the hover status
using StWidget methods instead of setting the pseudo class directly.
The (optional) spread radius allows to make the shadow bigger without
enlarging the blur value. Mozilla supports this parameter for the
-moz-box-shadow property.
