If the popover's relative-to widget is unparented/reparented, we end
up unparenting/reparenting the popover as well. In that case, at the
moment of reparenting, the widget might have been visible (and is
thus mapped again), but priv->window hasn't been set yet.
We must first set priv->window, and then call gtk_window_add_popover(),
that way gtk_popover_map() has its prerequisites straight.
https://bugzilla.gnome.org/show_bug.cgi?id=766323
gtk_widget_set_parent() will map the widget if the parent is mapped
and the widget is both visible and child-visible. As we currently
only set the child visibility after adding the child, we immediately
map all children that are added to a mapped stack, even when they
are not actually shown. Avoid this by setting the child visibility
before adding the child, so widgets are only mapped when shown.

Use g_drive_is_removable for external drives detection. Current heuristic

When starting a rubberband selection from an empty area, we could run
into crashes if the selection moves over the rows and then back out
to unpopulated area. Handle this case without crashing.

Use .marks-before/after to indicate the presence of marks.
As Lapo points out, compatibility with the previous names
is not really that important, since everything else changed
around it.

Warn about the situation when we've found a resource or file path,
but gdk-pixbuf fails to give us a pixbuf. This generally means that
either pixbuf loaders are not found or the shared-mime database
is missing.
It turns out that it is too hard (and in some cases, impossible)
to get this information from node positioning, so bring back the
.scale-has-marks-above/below style classes on the main node.
This should allow us to fix the 'pointy sliders'.

GtkScrolledWindow leans towards using the minimum size of its child
widget, unless the scrollbar policy is GTK_POLICY_NEVER. This is
probably fine for most GtkScrollable implementations out there.
Especially when using GTK_SCROLL_MINIMUM, which is the default for all
implementations inside gtk+.
However, this is not good for GTK_SCROLL_NATURAL children. eg.,
VteTerminal's minimum size is 1x1 and natural size is the number of
visible rows and columns requested by the user. We really want to use
the natural size unless the user has resized the window to change that.
https://bugzilla.gnome.org/show_bug.cgi?id=766569
This code tries to add the minimum content size, if one is set, to the
GtkScrolledWindow's size requisition. This is obvious from the check
for non-negative values of min-content-height and min-content-width.
Using MAX needlessly makes the code harder to read by implying that
there is more to it when there actually isn't.
Fall out from 0d9ebb501dhttps://bugzilla.gnome.org/show_bug.cgi?id=766569
When we are beginning to calculate the height, if the vscrollbar_policy
is not GTK_POLICY_NEVER, and there is no min-content-height, then we
need some small non-zero value to get started. The idea is to always
ask for at least enough to fit the horizontal scrollbar.
Simply put, this should be the mirror image of the corresponding width
calculation code.
Those who got used to the buggy behaviour might notice that their
GtkScrolledWindows are not as tall as they used to be.

Sometimes on wayland we're seeing a frame draw before the first tick
callback, where the window position has not yet been updated.
With this change, the window is properly positioned as soon as
gtk_stack_start_transition returns.

Fix testsuite/a11y/about.ui GtkAboutDialog :
"CRITICAL **: atk_hyperlink_get_start_index: assertion 'ATK_IS_HYPERLINK (link)' failed"
That is set widget->priv->accessible as soon as accessible object is generated.
When accessible object is created accessible->priv->widget is set,
if widget->priv->accessible is not , then _gtk_label_accessible_update_links
exits early, thus without creating the links on the accessible side.
(This as it checks for the widget to have the accessible set before proceeding).

GTK used to not emit GtkWidget::style-updated on widgets that weren't
realized. This sped up construction of complex widgetry in the early
days of GTK3 where we instantly invalidated on every change.
We don't do that anymore, so in theory (and in my limited testing with
widget-factory) this shouldn't be a prolem anymore.
What is a problem though is that postponing style-updated leads to 2
problems:
(1) Unrealized widgets will not emit style-updated which may cause them
to not properly update their state and return wrong values from
get_preferred_width/height() etc
(2) Emitting style-updated during realize can happen too late.
When a widget is not made child-visible by its parent (common
examples: notebook, paned) it will also not be realized when the
parent is initially shown. However, when they get realized later
(after a resize of the parent), they will emit style-updated (and
potentially queue a resize) during size-allocate.

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.

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).

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.
