Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
We claimed the gesture previously to keep it from propagating to the
underlying entry, but now that the entry is in a box with the two
buttons, we can do this properly and restore the previous long-press
behavior.
always initialize clips to the (content) allocation, don't walk up the
widget hierarchy in gtk_widget_set_clip, implement
gtk_widget_size_allocate in GtkSeparator. This way we don't end up using
uninitialized clip values.
The entire clip handling is up for major rework since we can't and don't
want to force every single widget to call _set_clip in size-allocate
implementations.
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.
Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
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.

When opening the value editor for any GtkAdjustment properties
in the inspector, the popover stretches out for miles, since
it reserves enough space to draw MAXDOUBLE. This is not useful.
Limit the space we reserve to 8 digits.
Always have Since: annotations at the very bottom, use the correct
ClassName::signal-name/ClassName:property-name syntax, fix a few typos
in type names, wrong function names, non-existing type names, etc.
When the spinbutton grows larger, distribute horizontal size to the
entry and vertical size to the buttons.
Obviously, horizontal size only matters for horizontal spinbuttons and
vertical for vertical spinbuttons.
Instead of having old and new style, now have a GtkCssStyleChange opaque
object that will compute the changes you are interested in for you.
This simplifies change signal handlers quite a bit and avoids lots of
repeated computation in every signal handler.
We can't use up_panel and down_panel as differentiators for the buttons,
because these window system resources don't exist before realize().
Just use a one-off enum for this purpose.

Use G_PARAM_DEPRECATED with deprecated style properties.
This will make it easier to identify and remove such stale
properties from css, since it will now trigger warnings.
This commit creates entry and button subnodes for the buttons
in GtkSpinButton. The nodes are ordered like this for horizontal
spinbutton
+ entry
+ image.left
+ image.right
+ progress
+ button.down
+ button.up
and like this for vertical ones:
spinbutton
+ button.down
+ entry
+ button.up
This arrangement requires cooperation from GtkEntry to place
the entry subnodes correctly, and some small changes in the theme.
This commit also fixes progress rendering in vertical spin buttons.
These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
With the 3.0 transition, this code went from just querying the entry's
height request to doing a full size request.
Then it got code to revert the features that a full size request does.
And then it grew code that manually computed the baseline.
Avoid this and just do what happened back in the days: Do a regular
height request.
This changes the semantics of the get_frame_size() vfunc wrt its
behavior towards subclasses overwriting the get_height() vfuncs, but I'm
happy to live with that.
Failure to do so results in custom styling leaking through in
the inspector. This is pretty obvious, now that the inspector
is using a separate display connection and is generally isolated
from style changes.
With the recent save-is-child changes, using
gtk_style_context_get_padding (context, different_state)
will now open a subelement.
This is not what we want, so we check the state whenever we get the
button contexts.
Changing adjustment via the property setter would not emit
value-changed, however changing it via gtk_spin_button_configure would.
This inconsistency had the following side-effects:
- Setting an adjustment with a different value would not update the
value shown by the spin button.
- Creating a spin button like this (common in GtkBuilder XML) will
not show the initial value:
g_object_new (GTK_TYPE_SPIN_BUTTON, "adjustment", adj, NULL);
Let's use the same code path (ie. gtk_spin_button_configure) for all
public facing API for setting adjustment. The code that handled the
details of swapping out the old adjustment with the new has been split
into an unset_adjustment method and the rest has been folded into
gtk_spin_button_configure.
A spin button really needs an adjustment to work, so we don't need
most of the NULL checks. However we do need to check in
unset_adjustment because setting a new adjustment during object
creation might try to unset a non-existent one.

Event controllers now auto-attach, and the GtkCapturePhase only determines
when are events dispatched, but all controllers are managed by the widget wrt
grabs.
All callers have been updated.
Those get in the middle more than help on these widgets, the widget
is already packed with clickable areas and having handles (and their
invisible clickable area around) hovering above don't help, plus the
purpose in most likely numeric values is a bit doubtful.
All touch events are either consumed by the up/down panels, or
the swipe gesture, all GtkEntry handling of touch events on the text
window is avoided, so handles to not appear anymore.
The propagation phase property/methods in GtkEventController are gone,
This is now set directly on the GtkWidget add/remove controller API,
which has been made private.
The only public bit now are the new functions gtk_gesture_attach() and
gtk_gesture_detach() that will use the private API underneath.
All callers have been updated.
We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
Cache the style contexts for the up and down panels, instead of recreating
them each time they are drawn or size requested. GtkSpinButtons were
many times slower to draw than other widgets because of the constant
style matching.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
We were adding one child too much to the style context path when
generating it for the internal buttons, which in turn caused sibling
selectors from the theme such as :first-child to apply to both buttons
under certain circumstances. Spotted by Lapo Calamandrei.
Add an internal API that allows GtkStyleContext to create a widget path
for the widget and with that bypassing gtk_widget_get_path() and that
function caching the path.
