nitems is never guaranteed to be defined in sys/params.h as it is meant
to be defined within a protected ifdef __KERNEL conditional.
Use G_N_ELEMENTS from GLib which is the proper way of doing this.
In gtk_entry_get_icon_pixbuf() we unreference the pixbuf that
_gtk_icon_helper_ensure_pixbuf() gives us back, since the function
doesn't return a reference, and by doing so we're able to return the
reference owned by the cached icon helper.
Since the icon helper method can return NULL though, if no icon
properties have been set on it, guard for != NULL before unreffing the
pixbuf, as that would cause a critical warning.

Right now, when we create a GtkModelMenu for a GMenuModel, we listen to
changes to the menu's attach-widget to detect when a toplevel
GtkApplicationWindow becomes available to fetch actions from it.
This unfortunately breaks this simple code:
GtkWidget *application_window = gtk_application_window_new();
GtkWidget *menu_button = gtk_menu_button_new();
GMenuModel *menu_model = get_menu_model();
gtk_menu_button_set_menu_model(menu_button, menu_model);
gtk_container_add(GTK_CONTAINER(application_window), menu_button);
Since GtkMenuButton creates a GtkModelMenu and sets itself as its attach
widget before it's added to a hierarchy containing a
GtkApplicationWindow.
Fix the bug by simply listening for changes in the window hierarchy, and
creating the menu model when the attach widget is added to an
application window.
https://bugzilla.gnome.org/show_bug.cgi?id=679454
When the menu is detached, the attach-widget property changes value to
NULL, so we should notify a property change, like
gtk_menu_attach_to_widget() does.

This is fallout from commit 257b42e2f9 -
those fields were already getting freed in
gtk_application_shutdown_x11() and my commit caused crashes on quit
instead.
Thanks to Rico Tzschichholz for reporting the bug and testing this fix.
As an addition to 1042372670, themes might
want to avoid using the hardcoded GTK defaults for legacy GtkStyle
values. Add a gtkstyle-fallback style class that can be used by themes
to tweak the legacy GtkStyle defaults.

Since we explictly call popup_menu with NULL when it's
keyboard-activated, we need to be careful and not access event->device
without checking for event != NULL before.
The signals for the action group were being disconnected when the action
group was explicitly removed from the GActionMuxer but the same was not
being done when it was finalized.
This means that a change in the state of an action group that used to be
associated with a finalized GActionMuxer would result in a crash. This
would happen for stateful application actions after closing a window.
We can't expose colors with alpha in the GtkStyle colors, since
GdkColor has no alpha. Currently we throw away alpha completely,
which fails very badly for completely transparent backgrounds,
which now is the default for most widgets, as it typically
end up with black-on-black.
We handle this by falling back on the default/previous colors for
transparent colors. This is is simple and avoids complete failure.

When using Shift-Tab to move the focus out of page content onto
the tab label, we end up in a situation where both Tab and Shift-Tab
move focus back into the page, which is not really what is expected
when the notebook is part of a dialog.
Instead, arrange things so that using Shift-Tab with focus on a
tab label moves the focus out of the notebook.
http://bugzilla.gnome.org/show_bug.cgi?id=669986
It turns out that we can end up removing a notebook child while
the tab is still 'detached'. Child removal causes
gtk_notebook_remove_tab_label() to be called on the tab label,
but that function did not deal with the eventuality that the tab
label may be a child of the dnd window.

Some builders using gtk3 outside of the GNOME cycle want an option to

Make GMountOperation look for an owner of org.Gtk.MountOperationHandler
if possible, and use it instead of the GTK-based dialogs.

This gets the current cell area of a particular item. Its similar
to gtk_tree_view_get_cell_area().

just calls the old code.

When a widget is app_paintable, its background should not be drawn by
the theme, thus we should not try to override its background again when
style-updated is fired.
This is a bit of a hack, but it fixes gray surfaces observed for DnD
windows with recent GTK+.
As used in Totem and gnome-contacts. The widget
takes either a GtkMenu or a GMenuModel to construct
its menu, and can be given a parent widget to use to
position the drop-down (as used in GtkMenuToolButton).

If the icon view is empty, we cannot get a reasonable size request from
the cell renderers. So all values we would compute are pretty much
useless.
So we special case it.
This also gets rid of a bunch of crashers from div-by-0 in corner cases.
https://bugzilla.gnome.org/show_bug.cgi?id=677809
This is useful for 2 reasons:
(1) Items actually exist and are clickable
(2) Size computations don't divide by 0
I've not seen problems with this in the wild (mostly because
item-padding defaults to non-0), but noticed this while fixing other
bugs.
Minimum size is necessary so you can see the item. If we can't get that
we need to scroll.
Natural as the maximum is used so that the spacing between items doesn't
increase when resizing the iconview, but empty space is added to the
right/bottom instead.
https://bugzilla.gnome.org/show_bug.cgi?id=677809
While working on the "iconview: Don't shrink items" patch I noticed that
gtk_icon_view_compute_n_items_for_size modifies the natural and minimum
item sizes it got from gtk_icon_view_get_preferred_item_size when
calculating the max number of items which will fit, but later on it
checks against these sizes when calculating the item_size, and these
checks expect these values to be unmodified.
This patch fixes this by modifying the natural and minimum values in
advance and doing all computations with modified values.
https://bugzilla.gnome.org/show_bug.cgi?id=677809
The previous code assumed that the width was always enough for more than
one column, which is obviously not correct when a number of columns is
hardcoded.
With this patch, it will now always check that the width is enough and
otherwise cause scrolling.

GtkToolbar doesn't have its own GdkWindow to draw on (it calls
gtk_widget_set_has_window(FALSE) in _init), but only an event window
(input-only).
Since gtk_widget_get_window() in that case will return the GdkWindow of
the parent container, by calling gtk_style_context_set_background() here
we're overriding the base background of the container instead of our.
While in most cases this doesn't have any noticeable effect, since
the toplevel GtkWindow will paint its background on top of it at the
beginning of the draw cycle, when the classic window hierarchy is
broken, such as when widgets are rendered through a clutter-gtk
offscreen embedding, the background will become visible, which is
undesirable.
Fix this by having GtkToolbar not call gtk_style_context_set_background
in its style_updated handler.
When I added the versioned annotation, I accidentally backdated
it, so the Deprecated: tag in the docs said 3.4, but the annotation
said 3.0. Fix it so we say 3.4 in both places.
When inline-selection is set, and the completion popup is showing,
pressing left abruptly jumps to the beginning of the entry text.
This is not expected, since the cursor is at the end of the text before
the left key is pressed, and this behavior is completely inconsistent
with how an entry would normally behave.
The behavior can be observed in Epiphany by selecting a completion match
and pressing left.
This patch changes the code so that it just runs the default entry key
press keybindings in such a case.

Mark the new_order argument as zero-terminated array, even though it does not
need to be zero terminated (it has an implicit length not given by a constant
or another method argument). It does not hurt if bindings append an extra zero
to the array as long as it has enough elements, and this makes the method
introspectable.

Remove the 'you shall not connect' message from this signal.
While it is a keybinding signal, using it from applications is
fine and, in fact, expected.
There are three bugs here:
- we should check if the value type is transformable instead of being
compatible, since that's all we care about in order to call
g_value_transform()
- the check is only meaningful in the direction
passed-in-type->column-type and not viceversa
- we should init the destination GValue to the column type before
calling g_value_transform on it, or the destination type information
will be missing and the method will fail
Thanks to Jasper St. Pierre and Colin Walters for all the help in
tracking this down.

Many themes want to render the trough background/stroke thinner than the
full height/width (which is constructed around the value of the
'slider-width' style property).
Read and apply the CSS margin from the theme on the trough component, so
that themes can make it smaller at their will without the need to
override the render_background, render_frame and render_activity methods
of GtkThemingEngine.

https://bugzilla.redhat.com//show_bug.cgi?id=812035 has
a stacktrace that shows recursion via
free_node -> unref -> dispose -> ui manager api
which ends in a crash, since we run free_node over the entire
tree and it leaves lots of dangling pointers behind.
So, better be careful by setting all pointers to NULL after
freeing them.
To make setting output directory and filename simpler in the PrintToFile
dialog two gtkprintsettings have been added GTK_PRINT_SETTINGS_OUTPUT_DIR
and GTK_PRINT_SETTINGS_OUTPUT_BASENAME.
This will reduce the code needed to implement a better name than "output.pdf"
and actually makes more sense than the existing setting
GTK_PRINT_SETTINGS_OUTPUT_URI which doesn't work seamlessly with
GTK_PRINT_SETTINGS_OUTPUT_FILE_FORMAT like the new settings do.
https://bugzilla.gnome.org/show_bug.cgi?id=657322
Not setting a URI but catching the activate-link signal is a
valid use of GtkLinkButton, but we shouldn't allow showing a
popup menu which offers to copy the URI if there's none.
Turn dead_doubleacute plus space into '"' and not into a double
acute because that's the way to enter double quotes on the

(cherry picked from commit 71164e57b9)
Code was using different places to compute the icon size when layouting
and when doing size requests. This resulted in non-matching behavior in
obscure cases. And that lead to iconviews that were too small.
