menu margins have been added has a hack to mitigate bug:
https://bugzilla.gnome.org/show_bug.cgi?id=591258 with gtk+4 this
doesn't work anymore on gtk+4, the margin should probably be moved
to the parent window node, but it's not selectable, commenting out
for now.
Since gtk+ draws more than the widget and allocates more size to it than
it knows about, this flag doesn't work anymore. Removing it (or setting
it to TRUE for widgets that used to set it to FALSE) fixes drawing
invalidation when these widgets get allocated a new size.
In gtk_container_real_set_focus_child(), we try to scroll to the
position of the new :focus-child if we have h or v adjustments.
gtk_widget_translate_coordinates() returns FALSE if neither widget is
realized or in other situations that cause output parameters x and y not
to be set. Thus, if the caller did not initialise x/y and uses them even
if the function returned FALSE, they are using uninitialised variables.
In gtk_container_real_set_focus_child(), we did not check the return
value but merrily went ahead and used x and y regardless. This is UB, as
revealed by Valgrind, as well as being pointless.
The trivial fix is to exit early if (!gtk_widget_translate_coordinates).

Commit 885bcd9fe4 trampled the bit here
that is meant to translate between the nominated focus child and the
actual innermost one that is used for updating the h/v adjustments.
So, we need to save the passed focus child before diving into its
children, then translate and get allocations between them both. This
makes GTK+ 4 behave like GTK+ 3 again: instead of priv->focus_child and
focus_child, we now have focus_child and child, serving the roles of the
nominated focus child and its innermost focus child respectively.
This also ditches the unnecessary call to Widget:get_focus_child(), as
Container::set_focus_child() gets that same new child as an argument.
process-stop-symbolic is unintuitive if represented as a stop sign as in
Adwaita, and completely ambiguous if represented as a cross like the
window close button in other icon themes.
Instead, use application-x-executable, which is already used elsewhere
as a fallback if no specific icon can be found for the application.

Don't beep when modifiers are released in entries.
This was an inadvertent change that snuck in with
the emoji support.
Also, don't beep while entering an emoji name.
There is entirely too much beeping here.
In GTK+ 2, the ch < 0x80 was ORd with klass->latin1_to_char, and that
was unconditionally set to TRUE in the class init function, so
effectively the ch < 0x80 never mattered before or served any purpose.
When klass->latin1_to_char was deleted from the class in commit
f760538f17, this check’s sense changed.
The resuls was that accel keyvals with gunichar value >= 0x80 stopped
being rendered as symbols, instead falling back to their keysym name.
Instead of recognisable symbols for these, we get raw, often obscure,
and untranslatable keysym names. This breaks accessibility as well as
client users who may be parsing such accels and migrating from GTK+ 2.
So, remove the < 0x80 to restore the behaviour from before said commit.

This commit adds some basic support for entering emoji by name
to GtkIMContextSimple. To begin an emoji sequence, use Ctrl-Shift-e
instead of Ctrl-Shift-u that is used for hex input. Otherwise, the
behavior is the same: you can can let go of the modifier keys and
end the sequence with space or enter, or hold on to the modifier
keys and end the sequence by releasing them.
Only a limited, fixed set of names is supported at this time, see
the GtkIMContextSimple docs for a full list.
• Add GtkLayout as a @See_also since it includes fixed-pos functionality
• Drop mention of the long-gone Linux framebuffer port
• Explain how to work around the problems with RTL text
Being addable to a ScrolledWindow is not interesting; now that SW
auto-adds a Viewport if needed, so can DrawingArea and any other widget.
Mention GtkFixed in case the reader just wants that bit of functionality
If query.return_type is not one we want, binding_compose_params() is
not called, and so params remains a NULL pointer. However, the code was
then unconditionally iterating it regardless. Don't if it is still NULL.
CID 1452218 (#1 of 1): Explicit null dereferenced (FORWARD_NULL)
15. var_deref_op: Dereferencing null pointer params.
This would only happen if the last element was deprecated, but it should
be avoided anyway.
CID 1388852 (#1 of 1): Out-of-bounds read (OVERRUN)
12. overrun-local: Overrunning array pseudo_classes of 16 32-byte
elements at element index 16 (byte offset 512) using index i + 1U (which
evaluates to 16).
This function clearly assumes the parameter children cannot be NULL, and
the call sites seem to perform enough checks to confirm this.
CID 1388869 (#1 of 1): Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking children suggests that it may be null,
but it has already been dereferenced on all paths leading to the check.
CID 1432024 (#1 of 1): Uninitialized scalar variable (UNINIT)
2. uninit_use_in_call: Using uninitialized value rect.x when calling
calendar_arrow_rectangle.
Add a default case to the switch which will bail out with
g_assert_not_reached(), which should reassure Coverity that the method
is always called with a valid value that is handled in the switch.
If value->values[i] is NULL, then values[i] was left uninitialised.
The code then reads each element of values[].
CID 1432029 (#1 of 1): Uninitialized pointer read (UNINIT)
11. uninit_use: Using uninitialized value values[i].
Our ::query-tooltip handler first checks whether the pointer is over any
of the icons, returning their tooltip if so, and if not chains up to
Widget::query-tooltip in order to show the text for the widget overall.
But ensure_has_tooltip(), which exists to update :has-tooltip based on
whether ::query-tooltip is needed, only set :has-tooltip to TRUE if any
icon had a tooltip, without caring whether the widget as a whole does.
That is asymmetrical and meant that if the Entry had a tooltip, but
subsequently all icons had their tooltips unset, :has-tooltip would be
set to FALSE, and hence the tooltip for the widget would become lost.
The fix is to set :has-tooltip to TRUE if the widget has a tooltip of
its own, and we only need to check the icons if that is not the case.
