Support scales when falling back to loading icons from the
icon theme.
In order to actually render scaled icons we add
gtk_icon_set_render_icon_surface which renders to a cairo_surface_t
which includes whatever scaling you need for scaled icons.
This draws an icon from a cairo_surface. We want to use this more rather
than render_icon as this means we can skip the pixbuf to surface
conversion (including allocation and alpha premultiplication) at
render time, plus we can use create_similar_image which may allow
faster rendering.
Add a very simple GtkWidget function for an "tick" callback, which
is connected to the ::update signal of GdkFrameClock.
Remove:
- GtkTimeline. The consensus is that it is too complex.
- GdkPaintClockTarget. In the rare cases where tick callbacks
aren't sufficient, it's possible to track the
paint clock with ::realize/::unrealize/::hierarchy-changed.
GtkTimeline is kept using ::update directly to allow using a GtkTimeline
with a paint clock but no widget.
This is for a very simple reason: The getter is returning a const value
and the font isn't const anymore. So we need to store the font
description somewhere but we can't reuse it as it's changing all the
time (yay animations, yay inherited values). Sucks.
So keep the hack in here but deprecate the function.
Themes may want to render handles differently depending on whether
the widget is in selection mode (2 handles enclosing a selection) or
cursor mode (one handle pointing out the insertion cursor).
Don't hook on the widget style context and set up instead
a widget path for itself. Also use a common style class
for both handles, with an extra top/bottom class for each
handle.
This is a helper object to allow text widgets to implement
text selection on touch devices. It allows for both cursor
placement and text selection, displaying draggable handles
on/around the cursor and selection bound positions.
Currently, this is private to GTK+, and only available to
GtkEntry and GtkTextView.
Deprecate public API where appropriate and make it no-ops.
Remove all calls to it.
Get rid of the 'transition' css property.
For now, this means spinners don't animate anymore.
In particular gtksettings.h and gtkstylecontext.h needed to be included
in lots of places now.
Also, I order the includes alphabetically in a bunch of headers.
This patch changes all uses of GDK_DEPRECATED(_FOR) in gtk headers
by the versioned variants, GDK_DEPRECATED_IN_3_x(_FOR). At the same
time, we add GDK_AVAILABLE_IN_3_x annotations for all API additions
in 3.2 and 3.4.
The new function provides an API that takes the PangoLayout and index
as input params, this way it handles strong and weak cursors internally
factoring out all code duplicated in the widgets that need to render
cursors.

By default, a background image is stretched. Instead, it is worth to
have a tiled background.
This patch allows background surfaces to be repeated or not, and should
be compatible with future extensions and CSS.

This is useful to e.g. theme notebook tabs differently according to
their position directly from the CSS sheet.
GtkNotebook support in a separate commit.

This way themes can use GtkComboBox.combobox-entry to match that
specific case, and GtkComboBox.combobox-entry .button to match the
button/arrow side of the widget.
The table was incomplete and out of date. Instead, just
put a list of links in that place, and move all the extra
documentation to the macros. Bug 653785
Fixes bug #Bug 639754, reported by Kjell Ahlstedt. gtkmm doesn't
use plain CamelCase for its widget type names, so in order to
distinguish widget type names from regions in the CSS parser,
the following checks are now done:
* if it contains an uppercase letter -> widget class (that should
also work for gtkmm)
* if it's a string compound by lowercase letters and '-' -> it's
a region, checks have been added in gtk_style_context_add_region()
and gtk_widget_path_iter_add_region() to ensure this.
GTK_STYLE_PROPERTY_BORDER_WIDTH is of style GtkBorder, not gint.
Also make it clearer what the definition and ordering of these 3
properties is. Reorder them in the header to be more logical.
This function will be needed in widgets like GtkTreeView,
since gdk_window_scroll() doesn't trigger the usual
mechanisms to update the invalidation area, this function
is needed together with it.
This function takes a region ID and cancels all animations
on or beneath that region (as in push/pop_animatable_region).
First user of this is GtkWidget itself, so unmapped widgets
have looping animations cancelled. Fixes bug #638119, reported
by Jesse van den Kieboom.
All colors are defined now in the default css, and classes have
been added so the bars are fully themeable (as opposed to
gtk_widget_override_*, which require changing the color map itself)
This method will render progress bars and spinners, these should
handle active and inconsistent states' animation progress in order
to perform animations.
It actually messed up with the state being actually set, and having a
transition animation running for it. Now this dichotomy is removed, and
gtk_style_context_state_is_running() only checks whether an animation is
running, leaving state checking to flags & GTK_STATE_FLAG_*.
The case for paned can be guessed out from the height and width,
for handlebox the orientation parameter doesn't make much sense,
and this way it could also be used for resize grips.
Animation regions are confined through gtk_style_context_[push|pop]_animatable_region,
anything that's painted between these calls will be invalidated if an animation starts
for any of the regions in the stack.
gtk_style_context_notify_state_change() may be called from widgets to indicate a
change for a given GtkStateType, in that case an animation will be started if there
is an animation description for the widget/state.
This support goes from the theming engines, which are able to retrieve
style for different combined states to the CSS provider, where several
state pseudo-classes may be specified, such as:
GtkButton:active:prelight {}
