This will be used to just detect when an edge of the scrollable area is
reached - as opposed to the edge-overshot signal that is emitted when
the user scrolls past the edge.

If a side of the box is 0px wide, make the corners owned by the adjacent
sides. This avoids spilling over of unwanted colors from the 0-width
side into the corner.
This is the fix that should actually have been part of
7e5ac3a58d but my amazing amending skills
got rid of it when amending the test.
Arrange things so that gtk-xdg-hinting==-1 and gtk-xfg-antialias==-1
end up as CAIRO_HINT_STYLE_DEFAULT and CAIRO_ANTIALIAS_DEFAULT in the
cairo font options.
This will not change anything on Linux desktops where xsettings will
always provide values different from -1. But on other platforms, we
can benefit from getting the platform-specific defaults in cairo.

When a tab is dropped, we have to remove it from the notebook to
insert it elsewhere. This is expected part of the tab dnd operation,
and we need to differentiate it from 'spontaneous' removals which
cause us to cancel the drag operation.
when the dragged tab is being removed during the drag operation,
we need to cancel the drag. To do so, we have to keep around
a reference to the drag context.
This should fix
https://bugzilla.gnome.org/show_bug.cgi?id=732051
Add a gtk_drag_cancel() function that can be used on the
source side to cancel an ongoing drag operation. This can
be useful, e.g. if the data that is being dragged becomes
unavailable.
It is a bit misleading to have one of the places in the sidebar
selected while in search mode, since the search is not relative
to any location. So, unset the sidebar selection when we enter
search mode.
If the search entry doesn't consume the key event, don't
change to search mode. Otherwise, we interfere e.g. with
Ctrl and Shift keys for selection.

If the grab belongs elsewhere, the window won't claim the sequence right
away. The sequence may still be claimed afterwards when window dragging
starts, but simple clicks won't be consumed this way.
This makes it possible to close popovers when clicking on the title region,
while still permitting touch/button 1 interaction for every other purpose.

- Specifically request GL version when creating context. Just specifying core
profile bit results in the requested version defaulting to 1.0 which causes
the core profile bit to be ignored and an arbitrary compatability context to be
returned.
- Fix GL painting by removing GL calls that have been depricated by the 3.2 core
profile.
- Additionally remove glInvalidateFramebuffer() call, it is not supported by 3.2
core.

Add helper for getting the main clipboard. This makes
the API usable for bindings (as GdkAtoms aren't usable through
gobject-introspection), and easier to use in C.

The property is useless to set (it only allows 'initial', 'inherit' and
'unset' as values), but it is used to track changes to the icon theme.
And as such, it can ensure that widgets can track when they need to
reload icons.

Gtk_container_cell_widget_set should chain up to its parent's set
function, not its parent's unset function. This was resulting in
accessibles being erroneously marked defunct after being created.
The GtkSelectionData does not own the model set with
gtk_tree_set_row_drag_data so change the out param to "transfer none".
This fixes a crash after multiple DnD actions due to the bindings
stealing a reference each time this function is called.
This also adds nullable and optional annotations for tree_model and path while at it.

Add ::next-match, ::previous-match and ::stop-search keybinding
signals that are bound to Ctrl-g, Ctrl-Shift-g and Escape. Also
add a gtk_search_entry_handle_event() function to handle key events.
Previously, we would not include any child widget on the first
allocation, which happens right after realize(), but before map(). No
widget is drawable at that point.
The rotation code in the draw_arrow function was assuming that the arrow
would be drawn pointing upwards but it was pointing to the right
resulting in the rotated arrows pointing in the wrong direction.
The recent refactoring caused a pi/2 rotation to be lost. Rather than
adding that back somehwere (to lose it again in the future), we just
draw the arrow pointing upwards as it is expected to do with a 0 angle.
Yes, I like playing around. To enjoy, add this CSS to your application
of choice (preferrably glade or something with lots of images):
GtkImage { animation: spin 2s linear infinite; }
You can thank me later.
The spinner is a regular builtin image now. There is no need to go
through the shadows code manually anymore as regular items do get
shadows automatically.
This also allows simplifying the actual spinner drawing code so that it
actually works.
The order in which properties are defined depends on the order in which
they are computed. And that means that properties can only depend on
other properties that are defined before them.
The next patches will need this reordering.
Instead of supporting every angle, just support top, right, bottom and
left and round the angle to one of those directions.
Adwaita overrides arrows anyway and doesn't even look at the angle, so
this should not be a problem.
Also, make it have a generic entry point with
gtk_css_image_builtin_draw().
The only feature lost so is the drawing of shadows for spinners, but
that will come back later.
The file chooser code now calls into the path bar in init,
starting an async operation. This unveiled that the path bar
code was not safe against being disposed early, by causing
a crahsh of the objects-finalize test.
Fix this by making the callback check for CANCELLED.
This was left unmodified when GtkScrolledWindow was made a windowed widget.
Displacing here by the widget allocation is not necessary anymore, since
we are invalidating the window set at these coordinates.
This patch is a simplification of a previous one by Timm Bäder.

GtkImageMenuItem always packs a GtkImage when it is synced with a
related action. This is unnecessary when the action doesn't have an icon
set and results in excess padding when a GtkImageMenuItem is put in a
menu bar (GtkUIManager does this).
Fix this by not creating the GtkImage for icon-less actions.

Just add a 3rd stop in the place where the gradients for the other
states have a 3rd stop. When running transitions between states, this
avoids cross-fades and instead uses the much faster gradient
transitioning code.
Instead of asserting, just print a g_warning() and try to work around
the problem.
I hope that g_warning() isn't too spammy for people that are hit with
it.
Also clarify the docs that not restore()ing after a save() is a bad
idea.

When creating the query path, explicitly specify if it's for a root node
or for a child. Relying on gtk_style_context_is_saved() is unreliable
(for example when updating the cache).
The last round of filechooser redesign work had left
search somewhat dysfunctional. This commit fixes things
up enough that search is once again a working feature
of the file chooser.
There are some cases where we can end up showing the path
bar without ever setting a file on it. One example is:
1) Open file chooser
2) Hit ~
3) Hit Ctrl-L
While this is a bit of a workaround, at least it makes sure
that we never end up with an empty space where the path bar
is supposed to be.
This gets rid of a bunch of awkward transitions. It's not a perfect
solution to the problem of "should we transition from this state" but it
gets rid of the ugliest offenders.
If this is done on dispose(), the widget may be destroyed (and its
controllers list NULLified) within _gtk_widget_run_controllers(),
causing warnings/crashes when it just tried to hop on the next
controllers.
Freeing the controllers here should be a safety net for implementations,
so it also makes sense to do this late. The widgets that choose to
free their controllers on dispose can still do so, and get
_gtk_widget_remove_controller() called for these as an indirect result.
g_utf8_get_char_validated() may return -1 or -2
return type is gunichar(guint32)
Therefore such checks like 'gunichar < 0' or 'gunichar > 0'
are always 'false' or 'true'(except when gunichar == 0).

If a gtk_style_context_invalidate() is called on a widget's style
context (which nobody should ever do, sheesh!) and we're animating, stop
the animations.
Fixes crashers in Nautilus.
When we get a leave event, we need to remove the over bit,
since we may not get motion events that tell us when we lose
proximity, but we don't have to fade out right away - that
will happen on its on due to inactivity a bit later. Having
the indicator stay visible for a bit feels more relaxed.
Since gsize doesn't work as a typename in a ui file,
we have to be careful not to pass pointers to wrongly
sized variables when getting the guint64 values out
of the model.

We still use symbolic icons for Copy, Cut, and Delete operations inside
toolbars and some menus, so it's worth pointing to the symbolic icon
names in the deprecation notices.

We need to clear the cache manually on full revalidates because
_gtk_css_change_for_child() will clear the full revalidation flags.
And then gtk_style_context_update_cache() will not do the right thing
(which is to clear itself).
Because we can switch from animating to non-animating pretty much
anywhere, do the check for animations unconditionally instead of trying
to cram it into the correct if path (and failing).
We now cache the results of lookups on the parent GtkCssStyle. This
allows sharing styles between widgets (recursively). However, this
only works if the styles can't potentially depend on siblings -
neither directly via sibling selectors or via position pseudo-classes
like :first-child.
Unfortunately, Adwaita currently uses first-child a lot, and in
particular for labels, which are the most common widgets.
The big benefits of this change are both less CPU - due to not needing
to compute styles again - and less memory usage - due to sharing of
the styles between widgets. Here's some nonscientific numbers I
collected while pondering the usefulness of this patch:
glade glade widget
demo demo factory
runtime styles styles

Adwaita now 18.9s 3800 970

Previously we looked at the save/restore state when determining the
parent. This is wrong in the case where we're updating the cache though.
So we now save the parent in the style info.
After the parent changes in commit
3a337156d1 we need to refresh the cached
styles after the current style. After all, they now depend on the base
style.
After 3a337156d1 style lookups still used
the parent context's style as the parent style, even though after a
gtk_style_context_save() the root style of the style context is the
proper parent.
Testcase attached.
Instead of keeping an animated style everywhere, we replace it with the
static style when nothing gets animated.
Apart from making the code cleaner, this gets rid of a bunch of animated
style values that do nothing but wrap a static style.
The only style that is animated is the style of the unsaved primary
node. So there's no need to create animated style objects for the other
ones.
There is a bunch of ugliness in the code currently. Further commits are
expected to fix them.
For now, this is only an implementation detail of the animated style.
The idea is to use GtkCssStaticStyle as the result of CSS queries and
then put a GtkCssAnimatedStyle on top that manages the animations. The
neat thing about this is that you can cache the static values.
GtkCssStyle is the base class to be used for all types of styles that do
exist.
GtkCssAnimatedStyle is the only implementation so far, that is exactly a
copy/paste of the old GtkCssStyle code.
I removed it in 14f5ce7108 because I
thought it was unnecessary, but it wasn't. When we build a tree like
this:
.matches ─┬─ .doesntmatch
└─ .alsodoesntmatch
We would get the changes for the .matches part returned. This is however
only right if that node of the tree contains results. If results only
exist with the child nodes (all of which don't match), then this part
should not match either.
GtkCalendar can have an invalid date — mostly at initialization. This
means that GDateTime construction may fail. We need to handle that case
gracefully, like the old code did.
This fixes the `notify` test suite, which started failing with:
/Notification/GtkCalendar:
GLib-CRITICAL **: g_date_time_get_day_of_week: assertion 'datetime != NULL' failed
inside the Continuous builder.
