Synchronizing the visible child with the switcher's toggle buttons can
lead to GtkButton::clicked being emitted twice. Once for the button
that was active before, and once for the button that we just activated.
This leads to notify::visible-child being called twice and one of
them is with the wrong child.
Let's deal with this in the same way we handle the visible child
changing underneath us.

The window state 'client_decorated' will only be set the window is being
realized. If anyone tries to get the shadow size before that it'd get
the with as if there always was no shadow.
This avoids negative sized opaque regions caused by the allocation being
smaller than shadow.

If we have a GObject property that is also a GObject, we should be able
to view additional information on that object (even if the param spec
is read-only).
We were relying on indirectly getting notify when fontconfig
configuration changes, by GtkSettings translating the timestamp
change into a style-invalidation, which gets fed through the
css invalidation machinery. That machinery has gotten good enough
at optimizing away redundant changes that it no longer emits
::style-updated in this case.
So, instead make the font chooser listen directly to what it
cares about: the fontconfig change notification from GtkSettings.
We can use the GtkSettings:gtk-fontconfig-timestamp property to decide
whether or not we should reload fonts on style and screen changes. This
should avoid doing a lot of work with large font collections when only
the theme has changed.

Add a new API, gtk_popover_set_default_widget, that can be
used to make a widget act as default while the popover is
shown. This is useful in dialog-like popovers.

Making a container focusable is rarely the right thing to do.
It typically breaks the focus chain, and makes the container
contents unfocusable, as was the case here.
We have a number of cases where properties should have their
default value overridden in a subclass, but haven't because thats
annoying to do. We also have properties where the absence of
an explicit value has context-dependent meaning.
Add a list of exceptions for these cases.
The previous commit removed default-valued properties,
but apparently that has a negative effect for grid
packing properties, so put the explicit value back.
Just using tracker does not work well if you are searching in
non-indexed locations, such as git checkouts or network mounts.
Ideally, we'd decide the 'best' engine to use for each location.
Since that is not easy to do, just run them in parallel for now,
which is the same strategy that nautilus uses.
Catch an error that indicates the file looks like a template,
and then try again, this time with the template parsing API
of GtkBuilder. This is a little iffy, since we need to create
a 'fake' type and instance to pass in, but it works ok in
simple tests.
Add the class and parent class name to the error message.
gtk-builder-tool will parse the error message and use the
class names for trying again to parse the file as a template.
Requires Vista and newer.
* Create surfaces with cairo_win32_surface_create_with_format
* Provide an rgba visual that can be distinguished from the system visual
* Make rgba visual the best available visual
* Enable alpha-transparency for all windows that we control
* Check for appropriate cairo capabilities at configure time
(W32 - 1.14.3 newer than 2015-04-14; others - 1.14.0)
* Check for composition support before enabling CSDs
* Re-enable transparency on WM_DWMCOMPOSITIONCHANGED
Windows that were created while composition was enabled and that were CSDed
as a result and will look ugly (thick black borders or no borders at all) once
composition is disabled.
If composition is enabled afterwards, they will return back to normal.
This happens, for example, when RDP session is opened to a desktop where a GTK
application is running. For W7/Vista windows will only re-gain transparency after
the RDP session is closed. For W8 transparency will only be gone momentarily.
Windows that were created while composition was disabled will not be CSDed
automatically and will use SSD (WM decorations), while windows that are CSDed
manually will get a thin square border.
If composition is enabled afterwards, these windows will not change.
This is most noticeable for system menus (popup menus are often generated
on the fly, system menus are created once) and some dialogues (About dialogue,
for example).

Add a convenience function that is like gtk_builder_get_object()
but stashes away a GError if a lookup fails. To make the error
message informative, the function takes a line/column pair.
Doing things this way is necessary because the custom_tag_end,
custom_finished, and parser_finished vfuncs don't take a
GError parameter, despite being called from a place where
we can report a GError back.
We want to clear the style property cache whenever things change in the
tree, not as we previously did only when those changes actually lead to
a different CSS style.
Instead of issuing g_warning, fill the provided GError.
This lets us test this error handling, and is the right
thing to do. Use the new GtkBuilder helpers and
g_markup_collect_attributes to do so.

cairo_rectangle_int_t was replaced by GdkRectangle in commit
552c29b488, but the type of the pointing-to
property was not changed.
To avoid breaking old code that sets or gets the property with a GValue
of type CAIRO_GOBJECT_TYPE_RECTANGLE_INT, transformation functions between
CAIRO_GOBJECT_TYPE_RECTANGLE_INT and GDK_TYPE_RECTANGLE are registered on
the first call to gdk_rectangle_get_type().

To calculate the shadow width, we look at the value of priv->fullscreen
and priv->maximized.
Those fields will have the actual value only after GTK receives back a
window state event though, so they will be wrong in _realize(). Look at
priv->fullscreen_initially and priv->maximize_initially too, to avoid
the size changing right after realize, which would make the window
flicker if maximized at startup.

Libinput will use 0.0f on the "scrolling finished" event, so check for this
instead of rounding (<1 values are sort of frequent on touchpads). This
impedes bug #745315 to resurface after commit d563b943ed.
When the scrolledwindow receives scroll events, it ensures the timeout to
maybe start the "snap back to edges" animation is reset, but it does nothing
about the animation source. It must be reset just the same, to maybe be
started after the timeout fires up.
Added another :not() to fix the first and last swatches in the
first section of colorpicker.
Dodge the artifacts due to stacked anti-aliased rounded corners by
increasing the radius of the base object by 1px.
We were only updating window buttons when the headerbar was
a direct child of the window. That is not the case in more
complicated situations, such as the split headers in gedit
or polari. To fix such cases, make the headerbar itself listen
for state changes on its toplevel.

This used to do the right thing, practically ignoring those event
if they went all through the event handler, unless this motion event
triggered the cancellation of this gesture from the event handler
of another controllers.
In this case, the controller would be reset, but the motion event
would still go through its handler, setting again
current_button/sequence as the motion event has buttons in its
modifiers. This leaves GtkGestureSingle with inconsistent data
that may interfere with future runs.

The code managing scrollbars visibility was too pervasively checking for
mouse devices, leaving pen/eraser/cursor devices with no scrollbars at
all. Relax these checks a bit, and actually toggle full-width scrollbars
on pen/eraser devices, so it is an easier target.

Since windows can be intermediate containers this is somewhat redundant,

gtk_application_shutdown clears the impl member, so all

When a treeview is destroyed while rubberbanding is going

When moving over a non-expanded indicator from the outside, we were
not expanding it, due to on_scrollbar being true. This can be seen

when receiving motion events over the indicator.

The "app_id" of a xdg_surface should be the ID that can potentially be
used to get the DBUS name or the .desktop file.
For GtkApplication programs this is often the ID passed when creating the
GtkApplication object, so when available lets use that.
As fallbacks, first try g_get_prgname as it often corresponds to the
basename part of the .dektop file for non-GtkApplication programs.
Otherwise use gdk_get_program_class, even though that string usually
doesn't conform to the expectations of xdg_surface.set_application_id.

If the icon happened to come from the drag site icon helper (ie. set through
gtk_drag_source_set_icon*), it would be referenced on the GtkDragInfo,
but not hooked into its context. This results on non visible drag windows,
until set_icon_helper() happened to be called on some path.
GtkRadioButton had a deficient copy of the focus sort code
in GtkContainer, causing focus to jump over the next button
in the list. Just use _gtk_container_focus_sort() here,

As of 74405cc, progress bars use a new design with values drawn on top
(or to the left) of the through instead of inside of it. This change
brought a number of regressions: the min-horizontal-bar-height and
min-vertical-bar-width style properties are not respected anymore. For
vertical progress bars, the value was drawn too close to the bar and not
centered vertically.
Fix this by respecting the style properties and drawing the value label
at the correct position.
Also, the xspacing and yspacing properties didn't server any apparent
purpose. Change their semantics to mean "the spacing between the label
and the bar". Hence, they only need to be added to the size request when
showing the label. Since we are changing semantics anyway, reduce their
default values from 7 to 2, to avoid and excessive gap.

As it is, GtkListBox model binding will work nicely as long as your
create_widget_func returns a floating reference on the newly-created
widget.
If you try to return a full reference (as any higher-level language
would do) then you will leak that reference.
Fix that up by converting any floating references into full references
and then unconditionally releasing the full reference after adding to
the box.

I managed to stall recent files today while trying to save a GTK

The direction in which the slider moves can be inverted by setting the
inverted property. But the draw method does not check this, instead it
checks if the direction of the widget is set to be right to left.
Call the should_invert function in order to determine if the direction
of the range should be inverted. It too checks the widget's direction,
but also checks the "inverted" property, and allows the range to be
drawn inverted even if it is vertically oriented.

Put the equality check in front. This allows better detection of when an

When recomputing CSS, we need a correct widget path in the fallback mode
where we're still using widget paths.
So we need to invalidate it everytime it actually changes, and not just
when emitting the style-updated signal.
Fixes css-match-regions reftest.
Clang complains that this check can never be true. Since this
is a argument range check which we do to catch bad input,
convince clang to not complain instead of taking it out.
clang complains that the expression involving sqrt() is not
constant, and thus refuses to accept it as a case label. So,
use precomputed values instead.

Break out a setter that manages the weak pointer, and

forgetting to disconnect the right signal handler in
some cases.
The other Radio* widgets have this convenience method that removes the
memory management of the opaque GSList used to handle the group from the
API usable from language bindings (especially the ones not based on
introspection).
This commit adds gtk_radio_menu_item_join_group().
https://bugzilla.gnome.org/show_bug.cgi?id=671362
Some arguments, like the group and the label of a RadioMenuItem, can be
NULL: the RadioMenuItem has all the code to deal with them. The argument
validation is too strict, though, for instance doing:
return_if_fail (IS_RADIO_MENU_ITEM (foo))
if (foo != NULL)
set_foo (foo)
Which is obviously incorrect.
This commit also modifies the annotations of the API, to ensure that
language bindings do the right thing.

If we create a RadioMenuItem without a group, and then set a group, the
menu item will still be set as active, which means an inconsistently
drawn radio menu item - as the RadioMenuItem will set the active flag on
itself, but then it won't reset it when it gets a new group.

If the widget has been destroyed since a DBus message had been sent,
we could be in a condition that the widget pointer exists but it does
not have a window.
This bails as if the widget didn't exist if there is no available
GdkWindow.
We also set the extents to 0 to be defensive since this is a vfunc
implementation.

Since these part really are the same in all of the x or y direction
and we don't blur in that direction we can just blur one line and
repeat it during drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=746468
There is no need to e.g. blur in the x-direction for the top part
of a box shadow. Also, there is no need to extend the mask in the
non-blurred direction.
https://bugzilla.gnome.org/show_bug.cgi?id=746468
For radius 1px the current implementation rounds down to a 1 px box
filter which is a no-op. Rather than creating useless shadow masks
in this case we bail out blurring early.
Another alternative would be to make radius 1px round up to a 2 px box
filter, but that would change the rendering of Adwaita which is probably
not a great idea this late in the cycle.

This allows monitoring the CSS tree. For now, moving a child to a
different position relative to its siblings while keeping the same
parent will cause a child-added + child-removed emission.
We need to properly track if a node needs to propagate invalidation
state information to its children. We didn't do this properly before and
that could lead to us forgetting to invalidate nodes in corner cases.
Do not propagate the TIMESTAMP change through the node tree, as that
causes lots of uneeded markings of nodes as invalid.
Instead, walk the node tree and find the nodes that have a non-static
style and only invalidate timestamps on those.
Only invalidate timestamps if the node is marked as invalid. We overload
the meaning of "invalid" as "tracks timestamps".
While I don't like the way this is written, it is an important
optimization because 95+% of nodes don't animate so timestamps don't
matter to them. But timestamps are invalidated 60x per second.
We don't return a NULL style to mean "no changes" anymore, instead
we check new_style == old_style to mean that.
Make sure the code reflects this, otherwise we'll send
GTK_CSS_CHANGE_PARENT_STYLE invalidations everywhere and screw up
performance.
Now that the widget node recomputes styles on update_style() we can just
call it during validate(). That way, we don't need the widget node to
manually compute its style.
If CSS values are queried from a widget, recompute them if necessary. Do
not emit style-updated until the validation phase however.
This way, we don't run into performance traps when style-update causes
invalidations that cause new style-updated to be emitted.
