After checking for rendered_surface, the call to gtk_css_node_get_style
can invalidate the style and result in rendered_surface being set to
NULL. This was result in some icon views appearing blank on
Endless OS on armv7hl, and this error:
Gtk-CRITICAL **: gtk_css_style_render_icon_surface: assertion 'surface != NULL' failed
Call gtk_css_node_get_style earlier to ensure we always pass a valid
surface to gtk_css_style_render_icon_surface.

add circle objects to the injected style for recoloring.
Should avoid randomly colored symbolic icon bits when circles are
in the mix as in network-vpn-acquiring-symbolic for example.
Otherwise, with CSD, we could have a discrepancy where gtk uses the
right values for the shadows whereas the gdk backend still uses the old
values, leading in some cases to invalid or negative min size being
computed (which, in Wayland, leads a protocol error).
https://bugzilla.gnome.org/show_bug.cgi?id=771561
The main corpus of the documentation for gtk_window_get_size() is still
full of X11-isms, so we should port it to something that is more
backend-agnostic. Additionally, having some examples would be nice for
application authors looking at a way to appropriately use this function.
If somebody decides to use gtk_widget_set_double_buffered() in the
middle of a draw() then there's the risk of calling end_draw_frame()
with an invalid pointer.
Some overeager compilers may warn about the double_buffered bit field
changing values and leading to a potentially uninitialized variable.
In order to avoid compiler warnings or crashes, we can simply store the
value of the double_buffered bit field at the beginning of the rendering
and use that instead of the actual bit field.

Not all occurrences of this warning can be fixed today, so put it behind
a G_ENABLE_DEBUG flag since it still shows legitimate problems even if
some of them are false positives.
The fix for bug 767468 had some unintended side-effects. This is
an attempt at doing the same fix (don't grab focus when we are
grab-shadowed), while avoiding the breakage, by using GTK+'s
internal tracking for grab-shadowed-ness.

Analogous to (un)mount operation, we now keep a reference around
during the ongoing operation and make use of the destroyed flag
to check if we are still alive or if we have been cancelled as
a result of the widget being destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
Since we hold on to a reference during (un)mount operations, we
don't trigger the cancellation of operations in finalize anymore.
Instead we now override the GtkWidget's destroy() and cancel any
ongoing operations there.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
The current code wrongly assumes that cancellation can only happen
as a result widget finalization, and consequentially does not
properly recover from it. Therefore if the operation is cancelled
as a result of user interaction, the entry is will stay disabled
and the spinner will keep spinning. This is fixed by removal of
the early bail out in case of cancellation.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
During mount and unmount opertions we keep a reference to the
GtkPlacesView around, so we have a valid view for the callback
code, even in the case that othe external references have been
dropped (i.e. the containing window gets destroyed).

This reverts commit 6af5033386.
Scrolled window behavior of propagating child natural sizes
has now been made optional, so there is no need to work around
this by setting a hard coded maximum content height anymore.
In gtkscrolledwindow.c, the return type of _get_propagate_natural_width()
and _get_propagate_natural_height() were accidentally gint instead of
gboolean, fixed to match the type correctly declared in the header file.
The code always assumed that getting a row at a certain 'y' was
possible but if the list box has more empty space than rows then a
valid row may not be retrieved.

Since we're using _get_rect_coords in size-allocate when allocating the
size of the child widget, use the newly introduced _get_rect_for_size to
calculate the difference between the passed size_for and the one we're
supposed to pass on to the child widget.
When calculating the requested size of a popover, we need to do the
exact same same thing _get_rect_coords did, but not for the
current popopver allocation. Add _get_rect_for_size that can be used for
this purpose
Making propagation of child natural sizes mandatory (or default, even) was
evidently a mistake as this causes dynamic content in a scrolled window
to resize it's parent when the scrolled window is competing for space
with an adjacent widget.
This patch instead adds API to control whether natural width and
height of the child should be propagated through the scrolled windows
size requests.
We were using __VOID for the SHOW_OTHER_LOCATION signal that
uses flags named SHOR_OTHER_LOCATION_WITH_FLAGS.
However, if a signal uses flags the marshal needs to use __FLAGS.
This patch addresses this using VOID__FLAGS as the marshaler parameter.
Thanks to Jan Steffens for pointing this out.

This GdkEventController is a helper object to handle pad events,
it allows setting a mapping to action names, to be triggered in
the given action group.
In order to help on places where advanced mapping/configurability
of pad features is not desirable, this controller also allows
passing a NULL pad device, meaning it will listen on all pads,
and/or passing -1 on mode/index, so an action applies to all
modes/features (eg. strips/rings).

The effect of transitions-enabled=true can now be
achieved using gtk_popover_popup/popdown and the effect
of transitions-enabled=false can be achieved using
gtk_widget_show/hide.
https://bugzilla.gnome.org/show_bug.cgi?id=769706
Since not chaining up in gtk_widget_show/gtk_widget_hide is not allowed,
we can't just implicitly delay the hiding in GtkPopover's hide
implementation. Fix this by introducing gtk_popover_popup() and
gtk_popover_popdown() to show or hide a popover with transition and
revert GtkPopover's show/hide implementation to apply their effect
without the transition.

The GtkHeaderBar gadget implementation was subtly broken: it called
gtk_widget_set_allocation both in gtk_header_bar_size_allocate (with
the actual allocation) and in gtk_header_bar_allocate_contents (with
the content allocation of the main gadget). Dropping the second call
fixes the render node conversion for GtkHeaderBar.
:toggled is triggered on :clicked, so using :toggled lead to the menu

Pick the W32 API for possible deadkey+<something> combinations
and prefer these to other sources of deadkey combos.
Specifically, if W32 API supports at least one combo for a particular
deadkey, only use that data and do not attempt to do other, unsupported
combinations, even if they make sense otherwise.
This is needed to, for example, correctly support US-International
keyboard layout, which produces a combined character for <' + a>
combo, but not for <' + s>, for example.
This is achieved by stashing all the deadkeys that we find in
an array, then doing extra loop through all virtual key codes and
trying to combine them with each of these deadkeys. Any combinations
that produce a single character are cached for later use.
In GTK Simple IM context, call a new GDK W32 function to do a lookup
on that cached combination table early on, among the "special cases"
(which are now partially obsolete).
A limitation of this code is that combinations with more than
one deadkey are not supported, except for combinations that consist
entirely of 2 known deadkeys. The upshot is that lookups should
be relatively fast, as deadkey array stays small and the combination
tree stays shallow.
Note that the use of ToUnicodeEx() seems suboptimal, as it should
be possible to just load a keyboard library (KBD*.DLL) manually
and obtain and use its key table directly. However, that is much more
complicated and would result in a significant rewrite of gdkkeys-win32.
The code from this commit, though hacky, is a direct addition to
existing code and should cover vast majority of the use-cases.
https://bugzilla.gnome.org/show_bug.cgi?id=569581
The new positioning-related properties had some quality of
implementation issues, such as incorrect initial values and
excessive change notification. This broke the notify test.
It tried to set the expand state if either xexpand/yexpand where true.
Due to a missing queue_compute_expand when adding a child it actually
only computed the expand state in case a child queued after being added
or in case a child had the expand property set (see optimization in
gtk_widget_set_parent)
In my case this broke layouts as a child of GtkCombBox started setting
an exand flag with 3.20 which queued a compute_expand, which in turn
propagated an expand child props set for a cell in the same table up
and overrode the expand child prop of a parent GtkBox.
This removes the custom compute_expand implementation to match the
behaviour of GtkBox (don't propagate child prop expand flags
but let child expand flags override the child props) and not get random
expand behaviour depending on whether and when child widgets set their
expand state.

Introduce a private API meant for abstracting how to get a handle
of a window that can be shared with other processes. The API is
async, since some implementations will require that. Currently,
only X11 is supported, which doesn't.
Based on a patch by Jonas Adahl.
When there's no useful shortcut accelerator set,
GtkShortcutLabel doesn't show any useful information.
To work around that, add a new property to set the
text to be displayed when there's no accelerator
available.
https://bugzilla.gnome.org/show_bug.cgi?id=769205
GtkShortcutLabel is a widget that displays a single
shortcut accelerator or gesture in the user interface,
and is currently used by the shortcuts window.
This widget, however, has public value as other applications
also may want to expose their own shortcuts. For instance,
it'll be useful for the Keyboard panel on Control Center and
the new shortcut editor in Pitivi, among others.
This patch exposes GtkShortcutLabel as a public widget,
and adds the necessary documentation.

Scroll history must refer to a timespan for the values to be valid, otherwise
we return FALSE, in this case the stored event(s) should be discarded anyway.
It could be the case that the last scroll event is received long after any
previous scroll event, in this case the last scroll event discards all "old"
scroll events, and scroll_history_finish() returns FALSE because there's no
time/offset deltas in the scroll history.
This is desired so we don't trigger the deceleration effect if there was no
effective velocity, we still must reset the installed scroll cursor, so take
it out of this if() condition.
I thought I needed ot rearrange the ordering of the animation-direction
values for the parser, overlooking the fact that we already parse them
backwards to address this very problem.

Always return an error if we fail to get a dbus proxy; the callers
are only looking whether error is set, not whether the return value
is NULL.
Use the same function for the inhibit proxy as well, and clean up
the sm_proxy in finalize.
This matches the behaviour of Mutter, Metacity and traditional X11
window managers on the window manager side, and is what we want
for at least gnome-terminal. I can't think of any reason why we'd
want incremental resize in any other tiled window.

Our property parser stops at the first match when looking for
enums, so we need to order our values so that we don't end up
with prefixes of longer names being found first.
I noticed this when the parser tried to interpret
background-blend-mode: color-burn; as "color, with junk at the end".
It also affects animation-direction, which is also fixed here.
CSS supports blend modes, in which a series of layers are
merged together according to the given operation or set of
operations.
Support for blend modes landed on Cairo, which exposes all
the commons and also the exquisites blend modes available.
Adding support for blend modes, then, is just a matter of
using the available Cairo operations.
This patch adds the background-blend-mode CSS enum property,
and adapts the background rendering code to blend the backgrounds
using the available blend modes when they're set.

we used to style infobars by using the .info, .question, .warning

or it interferes with everything with those styleclasses applied
like entries.
The header bar currently ignores the expand property on its
children. This commit changes the code to honor that property.
It divvies up any free space and distributes it equally to packed
children (with any left over space given out a pixel at a time
on a first come, first serve basis).
This commit also adds support for the title widget to be made
expandable.
It accomplishes this by using up the padding the title widget
is centered with.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
In order to support the expand property on children, we're
going to need to look at the size of the packed children
on each side of the title widget, up front, before allocating
them (to compute how much extra allocation each expanded child
gets).
This commit lays the groundwork for that analysis by splitting
the size calculation of each side of the header bar outside
of the loop that allocates each child of the header bar.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
With a headerbar, the widget in the center may be a label, constructed
internally, or a custom widget, constructed externally. The size
allocation code needs to handle either case the same way for the most
part. There's more than one place in the code that checks which of
the two widgets to use and does some operation on the selected one.
This commit simplifies the code by checking up front which one is the
center (title) widget and storing that in a temporary variable,
This allows reducing duplicated logic later on in the function.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
There's some extraneous MIN() calls that have predetermined answers.
This commit drops them and then simplifies a few redudant checks into
one MIN call.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
The size allocation code maintains an array of two elements,
to track the allocation of children packed into the two sides
of a header bar. Sometimes this array is indexed with 0 and 1,
and sometimes its indexed with GTK_PACK_START and GTK_PACK_END.
The latter happen to have the values 0 and 1, respectively, but
that's not really obvious.
For clarity, this commit changes the code to index those arrays
consistently, sticking to 0 and 1 across the board.
It's only possible to have a label or a custom title, not both.
The size allocate code confusingly treats them as independent.
That is confusing, because, as the code is written, it makes it
look like the space for the custom title isn't getting accounted
for.
This commit else-ifies some parts of the size allocate code for
clarity.
Firefox does a bunch of interesting things with GTK.
If the top-level GtkWindow does not have a "csd" style class associated,
Firefox will happily draw the contents of the container used to render
HTML and XUL directly on the top level's GdkWindow; on the other hand,
if a "csd" style class is found, the MozContainer will create a new
child window, and draw on it.
Then, Firefox will proceed to disable double buffering on both the
top-level window and the MozContainer (unless they are backed by the
same GdkWindow, in which case only the top-level will be
single-buffered) *and* it will add a GDK_EXPOSURE_MASK flag to the
MozContainer events for good measure (even if this is only needed for
GTK+ 2.x).
After landing the GdkDrawingContext API in GdkWindow, GTK enabled
automatic double buffering on all top-level windows backed by a native
surface, ad most users of single buffering rely on child widgets instead
of top-levels, and we'd still like to have the same double buffering
behaviour for all top-levels on all backends. Obviously, with Firefox
disabling double buffering on the top-level window, the change broke
their drawing mechanism.
Ideally, Firefox could be fixed to not disable double buffering on the
top-level window when MozContainer has a separate GdkWindow — i.e. the
CSD case — but since we did introduce a slight change of behaviour in
fringe users of the GTK+ API, let's keep backwards compatibility with
the old code for a little while longer, and create an intermediate Cairo
context unbound from the GdkDrawingContext, like we used to do until
GTK+ 3.20.
And ensure it's still visible before returning the keyboard focus to it.
Because of the extra ref, add a dispose handler that will ensure the
ref is lost (by popping down), although this should be already ensured
through other paths (eg. when the popup widget loses visibility).
This fixes a possible crash in dispose paths, where we might be restoring
focus on an already destroyed widget, and at a time where, if the toplevel
is being itself disposed, no new focus should be set.
https://bugzilla.gnome.org/show_bug.cgi?id=767849
If there are widget margins set, the whole popover will be displaced.
However the calculation of the tail position doesn't have this into
account, ending up with the tail being detached from the popover if
the margin grew too big.
We should not render the arrows invariably next to the GdkWindow edge,
but optionally displaced inside it depending on the widget margins.
Fixes the gtk3-demo "Popovers" demo case, whose GtkEntry popovers set
widget margins for some reason.
https://bugzilla.gnome.org/show_bug.cgi?id=767851
do_sort will crash if sort_func is not defined. Instead of adding a check
there in the hot path, just check for sort_func before invalidating the
sort of the underlying GSequence.
I noticed that some of the gestures did not show up in the
search results in the builder example in gtk3-demo, because
they share the same title and don't have an accelerator to
disambiguate. Include the shortcut type to handle this case.
The cellrenderer signals might be taking the grab somewhere else, at which
point it's dubious we should attempt to take the keyboard focus into the
treeview.
This concretely breaks popovers triggered from cellrenderer signals on
button press, because the treeview will attempt to grab focus
inconditionally then.

Previously a style cascade's parent could not have a parent itself. That
represented the two levels at which you could add a style provider: at
the screen level, with gtk_style_context_add_provider_for_screen(), and
at the style context level, with gtk_style_context_add_provider().
This commit changes no functionality, but this change will be necessary
for adding style providers in the future that apply to a subtree of the
widget tree. It relaxes the requirement that a style cascade's parent
must not have a parent, since in the future a style context may be
affected by any number of parent widgets' style contexts.

This is a bit of fallout from 34feba1, now that we resolve
the has_indicators value earlier than realize, it becomes
possible to call gdk_window_move_resize() before realization.
Just added the appropriate checks.
Instead of associating the GdkWindow that created the GdkDrawingContext
we can directly bind the Cairo context to the GDK drawing context.
Cairo contexts created via gdk_cairo_create() go back to not having a
GdkWindow associated to them, like they did before we introduced the
gdk_window_begin_draw_frame() API.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Instead of giving out Cairo contexts, GdkWindow should provide a
"drawing context", which can then create Cairo contexts on demand; this
allows us to future proof the API for when we're going to use a
different rendering pipeline, like OpenGL.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Widgets should support size requests before being realized in general,
otherwise this can cause flicker/resize at initial display time as
the toplevel window can make a request before realize/allocate.
This also makes the added testsuite/gtk/scrolledwindow.c test work again,
this was broken because we only ever calculate whether we are going
to use overlay scrollbars once the scrolled window is realized (and
the test case does not realize any window).
This patch does a couple of things:
o Removes the obscure 'extra_width' and 'extra_height' variables
making the request code exceedingly difficult to read
o Fixes the max-content-size properties introduced in bug 742281
so that they do not grow the minimum request.
o Cleanup of request code in general:
- min/max content sizes are clamped around the child request as needed
- scrollbar requests are only added in one place, after child request
sizes are calculated and without the extra_width/height thing.
If gtk_scrolled_window_add() has added a GtkViewport,
gtk_container_remove (GTK_CONTAINER (scrolled_window), child_widget);
or
gtk_container_remove(GTK_CONTAINER(scrolled_window),
gtk_bin_get_child(GTK_BIN(scrolled_window)));
removes both the added child widget and the viewport.

With the FTS5 query syntax, when using quotes to delimit the search phrase
the '*' token must happen after the quote, or will otherwise be considered
a character to match, go through the tokenizer, and end up ignored in
result.
This reverts commit 0943c9f6b2.
The commit caused unexpected breakage in gtk3-widget-factory,
and also broke the just-added max-content-size properties.
Needed to adjust this again after applying commit 4e5ecb7
for bug 742281. Now that we also have max content size properties,
pushed the addition of possible scrollbar sizes to after the
clause which clamps the child request size into min/max content
sizes.
Commit a01fe14 changed the behaviour of popovers when the focus leaves
them to stop child popovers being hidden when the focus leaves their
parent. However they are now a bit too reluctant to hide - if the
focus passes to an unrelated popover the first popover is not
hidden. Also if the focus passes to another widget that does not
perform a gtk grab then the popover isn't hidden until the user
presses a non-movement key or clicks outside the popover.
The solution is to go back to checking if the focused widget is a
descendant of the popover, but to include popovers and their related
widgets in the ancestry chain.
