Currently we use gtk_style_context_set_background() when the state flags
change in order to propagate the background color to the overshoot
window, but this is actually only needed because the window doesn't get
expose events, since we always draw a full background in draw().
This also fixes some problems when the GdkWindow of the scrolled
window's child is composited, as seen in oxygen-gtk3.

The implementation of transition for GtkCssShadowValue can return NULL
at least when the two values have a different inset; all other parts of
the GTK/CSS machinery (e.g. GtkCssArrayValue) handle this by returning
NULL too. Instead, GtkCssShadowsValue was returning an invalid value,
where "len" was set, but some values in the array were NULL, which would
lead to a segfault when this value is later evaluated by the compute
function.
Fix this by making GtkCssShadowsValue return NULL if a shadow transition
fails, like GtkCssArrayValue does.

Parsing a shorthand background property was running into unexpected
errors when trying position values where there were none. To fix this,
introduce a try_parse variant of the position parse function that
silently returns NULL.

... instead of from the intrinsic value. This way, we respect running
animations.
Note that the concept of "reversing" transitions is not implemented yet.
Otherwise, that value will never get reset and remain frozen in time.
This is problematic for example when the value is inherited and the
parent changes the value.
When positioning the scrollbar we were doing several miscalculations
when accounting for CSS paddings and borders. This also fixes a number
of problems with RTL and when scrollbars-within-bevel is FALSE.

I'm adding a bunch of fixes for gcc complaining about
-Wmissing-declarations after finding a bunch of cases today where I
had forgotten to make functions static in the CSS code.
This patch fixes the tests in gtk/tests.
After this last patch, the gtk/ subdir should now compile without
warnings when this flag is enabled.
This is part of a bunch of fixes for gcc complaining about
-Wmissing-declarations.
It puts functions into headers and includes those headers both where the
functions are defined and where they function are used.
Also remove the starting underscore from function names where
appropriate, as those functions are static now and not exported anymore.
This is part of a bunch of fixes for gcc complaining about
-Wmissing-declarations.

This set of patches makes private classes in gtk/*.c that use
G_DEFINE_TYPE() safe by adding definitions for the get_type() function
that can't be made static.
I'll add a bunch of fixes for gcc complaining about
-Wmissing-declarations after finding a bunch of cases today where I had
forgotten to make functions static in the CSS code.
A thorn in those patches is G_DEFINE_TYPE() which doesn't allow making
the get_type() function static, so I added definitions for that function
above the G_DEFINE_TYPE().
After those patches, GTK should compile without warnings when this flag
is enabled.
It seems we missed updating this since GTK+3, widgets cannot be
allocated less than the size they requested in thier request
phase, and explicit sizes are used only to grow the size request.
This is intended mainly to speed up the current situation with spinners
on debug kernels. Because we now don't use a cross-fade to draw the
transition but instead have a real gradient that we draw, we don't need
to use the slow cross-fade code.

We need to store the border widths independant of them being set to 0 by
border styles, because otherwise we'd need to track that dependency and
recompute on changes, and I don't want to add more entries to
GtkCssDependencies just for this special case.
By moving the code that does the setting to 0 from the compute stage to
the query stage, we can achieve this.
Now we need to just be aware that the actual value stored is not set to
0 when we use gtk_css_computed_values_get_value().
Otherwise the evil widgets that don't chain up their map and unmap
vfuncs will not get updated style contexts. This is in particular true
for GtkWindow and the CSS Theming / animated backgrounds demo in
gtk-demo.
Here's the shortest description of the bug I can come up with:
When computing values, we have 3 kinds of dependencies:
(1) other properties ("currentColor" or em values)
(2) inherited properties ("inherit")
(3) generic things from the theme (@keyframes or @define-color)
Previously, we passed the GtkStyleContext as an argument, because it
provided these 3 things using:
(1) _gtk_style_context_peek_property()
(2) _gtk_style_context_peek_property(gtk_style_context_get_parent())
(3) context->priv->cascade
However, this makes it impossible to lookup values other than the ones
accessible via _gtk_style_context_peek_property(). And this is exactly
what we are doing in gtk_style_context_update_cache(). So when the cache
updates encountered case (1), they were looking up the values from the
wrong style data.
So this large patch essentially does nothing but replace the
context argument in all compute functions with new arguments for the 3
cases above:
(1) values
(2) parent_values
(3) provider
We apparently have a lot of computing code.
This is needed for the SELECTION_NONE mode where nothing is ever
selected, but its also needed for CTRL-<key> keynav that moves the
focus without changing the selection.

Currently the GdkWindow used for dragging is created once when
the first drag starts, and the reused identical each time.
Instead, just recreate it for each drag, with the correct size.
This reverts commit f2cb8f1270.
The patch actually didn't work for at least text. I currently have no
clue why, but I suspect it requires investigating Cairo code and
recording surfaces, and I'll not do that right now.
Split out the blurred shadow rendering in three steps:
- creation of a surface of the appropriate size - we use the clip
rectangle as a good measurement for the size, since we won't render
out of it anyway
- painting the unblurred shape on the surface - this is responsibility
of the single shadow implementations
- blur the surface and compose the result back on the original cairo_t
This means we can share code between the implementations for the first
and third steps; it also makes the code independent of the rendered
size, so we can avoid passing down a cairo_rectangle_t with e.g. the
icon coordinates.
The code accesses pixels in a chunks of 4 bytes, so we must only support
formats where the size of a single pixel is 4 bytes.
Fix RGB24 to be 4 bytes (the alpha channel is ignored) and disallow A8.
We were adding one child too much to the style context path when
generating it for the internal buttons, which in turn caused sibling
selectors from the theme such as :first-child to apply to both buttons
under certain circumstances. Spotted by Lapo Calamandrei.
As long as we don't have an API for explicitly inverting the bar, it
makes more sense for the progress in vertical orientation to fill from
the bottom.
In the event that a GtkAccelKey was present for the closure but it
contained a keyval of 0 the previous code would show "". After the
recent adjustments, "-/-" would be shown in this case.
It turns out to be a pretty common case, so fix the logic to stop using
'0' as a magic value to mean "don't have an accel" and add a separate
boolean for that purpose.
This reverts commit 1f5dea9eba,
since it was causeing noticable behaviour changes.
Previously, GTK_DATA_PREFIX=/ ./gtk3-demo would start
gtk3-demo with the Raleigh theme. With that change, it
was starting with no theme at all (i.e. all black).
While regular animations should always be created, transitions should
not. This patch allows to express this by passing NULL as the values to
transition from.
It also adds a gtk_style_context_should_create_transitions() function
that returns TRUE when transitions should be created.
... that actually was both wrong, a performance failure and has been
there since the original checkin.
Updating the cached style data absolutely does not mean clearing all
cached style data first. There's nothing to update then.
This will be useful to not trigger updates all the time when nothing is
happening (ie due to animations being paused or due to them having
reached their final value).
This adds the GtkCssAnimation class and the code needed to hook it into
GtkStyleContext. It takes the values out of the CSS "animation"
properties and does animations. See
http://dev.w3.org/csswg/css3-animations/
for details.
Note that the code for starting and stopping animations with widget
visibility doesn't work yet.
This change is necessary because the old code did not accound for corner
cases (like translucent child windows), which could stop
gtk_widget_queue_resize() to not trigger redraws.
Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().
Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.
Remove the private header file.
Simplify the code a bit by making the initial populate part of the
bind() call.

Add an API to GtkAccelLabel for hardcoding the accel key to be displayed
(ie: allowing us to bypass the GtkAccelGroup lookup).
Use that from the GMenuModel-based GtkMenu construction code instead of
passing around the accel group.
This makes accel labels work in bloatpad again.
This patch effectively removes any hope of automatic runtime accel
changes in GMenuModel-based menus without additional application
support but it leaves the door open for this to be supported again in
the future (if we decide that it's important).

Add support for a stateful action associated with a submenu. The action
state is set to TRUE when the menu is shown and FALSE when it is
unshown.
This is useful to avoid unnecessary processing for menus that have
frequently-changing content.
A possible future feature is to add support for asynchronously filling
the initial state of the menu by waiting until the action actually emits
its state-change signal to TRUE before showing the menu.
A silly example has been added to Bloatpad to demonstrate the new
feature.

In gtk_menu_bar_draw, the check for shadow type != none
disables rendering of the background instead of the frame.
The check should be moved down to gtk_render_frame.

A button is highlighted if the private variable in_button is TRUE.
This variable is set when the pointer is over the button and cleared when
it left the button. When a button is hidden while there is the pointer over
it, GTK generates a leave notification event, in_button is set to FALSE.
But when a button is removed from a container but not destroyed, it is
unrealized and loose its window. It cannot receive the leave notification
event and in_button stay TRUE. So when the button get a new parent it is still
highlighted.

Scroll to the selection when setting it so the selected font is
visible on screen. This is especially useful if an initial font is
set for the user to see it.

Previously, we would avoid setting the prelight state flag when
button_down was TRUE and draw_indicator = FALSE, which is the normal
case of a GtkToggleButton during a mouse press.
It looks like this behavior was introduced a long time ago with commit
b94e6c0a80. I believe the reason was that
a widget in GTK2 couldn't have more than a single state (e.g.
hover+active) at a given moment.

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 to allow animating arrays properly. I'm not really thrilled
about this solution (we leak propertys into the values again...), but
it's the best I can come up with - I prefer it to having N different
array types...
I want to get away from the ability to have 0-length arrays, all css
arrays are single element.
Even if the element is "none", it is still a "none" element.
GtkTextHandle is used to indicate both the cursor position
and the selection bound, dragging the handles will modify
the selection and scroll if necessary.
Backwards text selection is also blocked for touch devices,
so the handles don't get inverted positions and possibly
obscure portions of the selected text.

important though on GtkTextView, as inverted handles may
obscure portions of the selected text, good for consistence
though)
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.
