Cancelling the gesture causes the last_event pointer to become
invalid. Make a copy of the event so we can keep using it
regardless of the gesture state.
At one point, the sidebar was using gtk_treeview_set_tooltip_column,
which expects tooltips to be markup. With the listbox-based sidebar,
we don't do that anymore. So don't escape the tooltip text.

We're measuring both the width of the minimal and the maximal value for
the value gadget, but only give the value the minimal width for its
current value, resultnig in an always left-aligned value.
Fix this by assigning the width of the value gadget to the value layout
and letting pango align the text inside the layout.

Menus are placed vertically by definition, it does not make much sense
to support horizontal axis for scrolling.
Use GDK_EVENT_STOP/GDK_EVENT_PROPAGATE instead of TRUE/FALSE and add a
default case to return GDK_EVENT_PROPAGATE for unhandled events.

On X11, we get both smooth and emulated scroll events, whereas other
backends such as wayland will give smooth events only with touchpad
scrolling.
Discard emulated scroll events so that we get consistent behaviours
between backends.
Allow for both horizontal and vertical smooth events for scrolling so
that horizontal scrolling still works without emulated scroll events as
well, again for consistency between gdk backends.

Some compilers we support, such as pre-2013 Visual Studio, does not support
for INIFINITY, log2() and exp2(), so check for exp2() and log2() during
configure, and use fallbacks for them and INIFINTY if they are not found.

Children tend to call back into the scrolled window while being removed
and that doesn't work too well if the scrolled window is destroyed
already as Christian Hergert found out.
Depending of float rounding during target calculation, the size of the
GtkRevealer can be set to zero will the animation is not finished.
If the GtkRevealer is in a GtkPaned, it will be hidden and so the animation
will be stopped before it is finished.
In this case, force the emission of the child-revealed signal to let
client code know the animation is finished.
https://bugzilla.gnome.org/show_bug.cgi?id=765973
This was another very frequent use of qdata. Since we typically
have only one or two display objects, storing the display-settings
association in a simple array is faster than using object data
or a hash table.
Christian Hergert reported seeing webkit crashes with recent
GTK+. The stacktrace points at the CSS machinery calling into
GtkSettings to get the font name, and then getting surprised
by a property notification that triggers style validation.
To avoid this, query the font name xsetting right away when
we get set a screen.
This will almost certainly overwritten before the widget gets
to the screen, but while we are doing this, we might as well
use the same state that we initialize the widgets state to.
Instead of creating 2 pango layouts in every draw() and on in
_get_content_size (and calling into gettext twice in both cases), just
keep the layouts around and create them in only one place.
I was somehow under the misconception that we'd get GdkEventSettings
events for all the xsettings at startup. That is not in general true,
so we need to make sure that we check for the xsettings value before
we use them, or derived fields. Update all the private getters to
do so; and fix settings_update_font_values() to cope with font
descriptions that might miss the family or size.
I mistakenly assumed that gtk_settings_init was already doing
something to trigger a notify for all properties. It doesn't,
so we have to ensure that settings_update_font_values() is
called at least once.

The fallback code for rendering builtin checks, radios
and expanders was using border parameters. With the generic
gadget borders using the same parameters, this was giving
double borders.
Before commit 6c1bee2377 we were setting an attribute of GtkNotebook
to track the pressed button if the pressed button happened on the
tab itself.
Later in the motion handling code we were checking whether the private
pressed button attribute was set or not in order to handle a tab dnd
or not.
In commit 6c1bee2377 the code changed and set the pressed button
variable unconditionally, which means, a motion event from within the
tab content triggered a tab reordering.
This happened only if the children hierarchy have a widget that bubbles
up both button press event, which sets the private pressed button
attribute; and motion events, which started the tab dnd checking the
private pressed button attribute.
A widget that experienced the regression was GtkListBox.
In order to fix it, set the button pressed variable only when it press
the tab itself, not the content.

Specifically, this URI is not supported on Windows, but GFile will
do its "best" and turn it into GLocalFile("$pwd/network"), with
spectacularly bad results.

We only keep one align flag per child, so it seems odd to
keep separate h/v expand flags. Just keep one expand flag
and interpret it according to orientation. Allow setting
the expand flag for child widgets too, though, so we can
make widget expand without interfering with the recursive
widget expand flag.
Update all callers.
Use the new possibility of expanding child widgets to make
the label of check and radio buttons expand. This fixes
unexpected behavior of these widgets in RTL in some places.
https://bugzilla.gnome.org/show_bug.cgi?id=765742
In RTL, we want to interpret GTK_ALIGN_START and _END
in the opposite way. Since we don't give gadgets a text
direction, just allow setting an align_reverse flag
to the box gadget.
If there was a piece of text in the cell, then when the edit
entry is shown for that cell, it should have a piece of text
in it roughly at the same location.
Therefore, when child widget is enlarged (child preferred
size exceeds cell size), extra width should be added by
extending either left or right edge depending on text direction.
If after that the child sticks outside of the treeivew visible region,
try to push it back inside (breaking its alignment with the
cell), again, giving preference (i.e. adjusting it last)
to either left or right edge depending on text direction.

This avoids the g_source_remove(), g_source_destroy(),
g_timer_source_new(), and g_source_set_name_by_id() in the common case.
Instead, we reuse our previous source and update the ready time to our
new deadline. We lose the coalescing with g_timeout_add_seconds(), but
that is not going to help in the common case anyway (unless you have
three hands and can scroll multiple pixelcached backed widgets at once).
https://bugzilla.gnome.org/show_bug.cgi?id=765640
In non-composited environments, we were ending up with all-black
drag icons, because nothing was drawing the background of our new
toplevel. Fix this by drawing background when we are not composited.
We don't do this when composited, since we want to allow transparent
icons.
GtkPlacesView currently provides no example of
server addresses, which may confuse users.
To fix that, add a helper popover with some
guidance on server addresses.

The documentation clearly says that the widget is not destroyed,
but we were in fact failing to keep it alive, since it was still
a child or the icon_window when we destroy that. Fix this by
reparenting the icon_widget out before. Also, deal with the
possibility that the application might destroy the widget
halfway through, for whatever reason.
There are various functions to access links based on their index for
a11y. We can spare quite a few lines of code by just using
g_list_nth_data instead of iterating over the list ourselves.

We perform lots of gadget allocations that require allocating a
GtkBuiltinIcon. One notable example is the scrollbar for a scrolled
window.
In the process of doing this, we often calculate baseline information that
isn't necessary. With how much this code path gets exercised, its worth
catching the result for the common case, which is that the font-description
has not changed and we are using the default language the application
was started with.
This simply caches the previous result and verifies that we can reuse it
with pango_font_description_hash() and a simple language check.
Numbers below are scrolling through a textview with GDK_KEY_Down.

When decelerating the kinetic scroll, we can get into a position where it
looks like we are stuttering. This happens because the amount we move is
so little that it takes multiple frames to make forward progress by one
pixel.
This prevents that by detecting when we have reached the slow stutter of
the deceleration and simply stops the deceleration phase immediately.

This has several benefits:
- Less code in GtkApplication. The accels handling is something
self-contained, and GtkApplication now delegates the work.
- For the accels functions, there is now a distinction between static
functions and functions in the gtkapplicationaccelsprivate.h header,
which makes the code easier to understand, because we have a good
overview just by reading the header.
- The struct _GtkApplicationPrivate is now easier to find instead of
being in the middle of the file.
https://bugzilla.gnome.org/show_bug.cgi?id=764879
These will become the functions present in the
gtkapplicationaccelsprivate.h header.
The gtk_application_accels functions deal with detailed_action_name's
instead of action_and_target's. action_and_target is an implementation
detail of Accels.
The added function prototype is temporary, it'll be removed in a later
commit.
https://bugzilla.gnome.org/show_bug.cgi?id=764879
When the current cursor_row is taller than the page_size we get from the
GtkAdjustment, the previous code would not actually cause any scrolling,
so make sure we just take the row after or before the cursor_row in that
case.

These runtime checks were being performed whether or not we were in a
debug build. Using GTK_DEBUG_CHECK() will compile out of production
builds, as it will result in something like:
if (G_UNLIKELY(0))
which the optimizer can prune.

This first adds a common autotools module that can be included by
the Makefile.am's to generate the file lists and the g-ir-scanner/
g-ir-compiler command lines to build the introspection files.
The autotools files for gdk/ and gtk/ are then updated to generate
the full file lists needed to build the introspection files, with
the full command lines for g-ir-scanner and g-ir-compiler as NMake
Makefile modules that can be used to build the introspection files
for Visual Studio builds.

https://bugzilla.gnome.org/show_bug.cgi?id=765134 shows
a stacktrace where we end up with arrow_gadget being NULL
despite the conditions for its presence being satisfied.
This commit makes sure we call update_arrow_gadget() whenever
any of the conditions changes. This should fix the reported
crash.
broken from my previous commit about rounded corners, dialogs
doesn't use the "window" node, but the "dialog" node, so use the
.background styleclass in the selectors which is more generic.
1) g_print() can be redirected
2) g_print() does some extra processing, such as character set conversion.
Specifically, on W32 it will detect system codepage via GetACP(),
and will convert UTF-8 output into that codepage, even though
the output should stay unchanged (whether gtk-builder-tool interprets
strings from ui files as UTF-8 is a separate matter).

When clearing the icon helper, we need to invalidate it. Otherwise the
previous icon keeps lingering along.
This is not relevant inside gtkiconhelper.c where other code causes the
invalidation, but happens when external code calls
_gtk_icon_helper_clear().

Fixes a couple bugs...
- Pixel font sizes in css would render as point sizes.
- For em font sizes, where the parent size was set and not default, we would
incorrectly convert a pixel value from points to pixels.
We'll always grab the default font size in pixels so we don't keep confusing
things.
Worth noting that gtk css font-size will still behave differently than the
web. Pango interprets font-size differently.
Because of our port of css animation and css transition to
progress tracker, we should not think of animated styles as
immutable objects that can map any timestamp to css values.
Rather, timestamps can correspond to different values depending
on the value of GTK_SLOWDOWN over the course of the animation.
To keep animated styles and style animations totally immutable,
we will not share styleanimations between animatedstyles, and
make a new copy of a styleanimation for each timestamp.
