... and actually set the widget on the style context. Note that this
function does not take a reference on the widget, which is a very good
reason to keep it private.
This way, we don't have to do magic inside GtkStyleContext, but have a
real API.
As a cute bonus, this object implements GtkStyleProvider itself. So we
can just pretend there's only one provider.
We now store the symbolic colors as a GtkCssValue which means that
we can reuse the color when resolving and storing the color in
the computed values in the style context.
Additionally we keep a last_resolved GtkCssValue cache in the
GtkSymbolicColor, and if resolving the color returns the same as
last time we reuse the old value. This further increases sharing
of Css Values.
Also, in places where we're computing a new CssValue based on an
old one, make sure that if nothing changes we're returning a reference
to the old one, rather than creating a new identical instance.
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 reverts commit c276f53796 and
implements the same feature using the compute function.
A nice side effect is that gtk_style_property_get_border() and
gtk_style_property_get("border") to the same thing now.
We now use the GtkStleProviderPrivate interface, which hopefully is
faster and more conformant to CSS. Long term, it definitely should be
both.
I would have liked to split this up into multiple commits, but couldn't
find a way.
When gtk_render_arrow() is called, always add an ARROW style class to
the GtkStyleContext before rendering, so themes can specify a different
color for it.

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.

From the css docs at http://www.w3.org/TR/CSS2/box.html:
8.5.1 Border width: 'border-top-width', 'border-right-width', 'border-bottom-width',
'border-left-width', and 'border-width'
Computed value: absolute length; '0' if the border style is 'none' or 'hidden'
At the toplevel we have _gtk_theming_engine_get, which lets us pass
in a property context with (atm) the size to get the property for.
Then there is a lot of plumbing to push this down into the lower
layers of the style property code until finally hitting
the property resolvers.
I need this because I will be adding a property resolver for win32
theme parts, and they render differently depending on the size
(i.e. they don't scale linearly). The idea is that the code
to get the background properties will pass in the final size
and we will resolve the theme part specification to that particular
size.
If the old non-context calls are used we just hardcode a size
of 100x100.
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
... and implement the CSS font properties:
- font-size
- font-style
- font-family
- font-weight
- font-variant
This is the second try at this. The first was backed out previously due
to bugginess. Let's hope this one survives a bit longer.
Also makes the font-family CSS test work again.
The hack in gtk_style_context_get_font() was causing segfaults in
combobox code. This is not acceptable and I'm not awake enough to fix
it, so just reverting until it's fixed sanely is easiest.
This reverts commit cf6bfbdb17.
It was unclear in the docs what happened if
gtk_style_context_add_provider() and
gtk_style_context_add_provider_for_screen()
were used with the same priority.
It is used to get the default providers, without them
the style context can't do much. A check for NULL screen
is done before any sensitive call to
gtk_style_context_set_screen(), in the hope that any widget
will open the display before doing anything related to
styling. Fixes bug #641429, reported by Bastien Nocera.
Move the private get_cursor_color method belongs to StyleContext. Change
the api so that retrieving both primary and secondary color is possible.
I left the method private for now, though it should probably be public
as all the other getters.
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.
This patch adds more detail to the explanation of CSS, and also
adds documentation about which files are read.
We also make :focus an alternative to :focused (since :focus is
a standard CSS pseudo-class).
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.
This is now used throughout in order to have the full path for a given widget,
including intermediate named regions, the default implementation just returns
the GtkContainer's path copy, no intermediate regions between.
