These functions were not implemented when the sizing changes
landed before GTK 4 was released. This fixes an issue with non-
resizeable windows not reacting to layout changes.
Fixes#3532
According to OpenGL spec, a shader object will only be flagged
for deletion unless it has been detached; when a program object
is deleted, those shader objects attached to it will be detached
but not deleted unless they have already been flagged for deletion.
So we shall detach a shader object before it is deleted, and delete
it before the program object is deleted best.
Some GTK based applications such as Qemu UI create and manage
EGLSurfaces associated with the relevant GdkSurfaces. In order to create
an EGLSurface, there needs to be a way to pass the native window
object to eglCreateWindowSurface(). While running in an X environment,
the native window object can be obtained by calling
gdk_x11_surface_get_xid(). Likewise, the native window object can be
obtained by calling gdk_wayland_surface_get_wl_egl_window() while
running in a Wayland environment. Therefore, this API needs to be
exposed to apps.

If set to TRUE, does not call the free func for the removed items.
This can be used to move items between arrays without having to do the
refcounting dance.

Depending on the input driver, we will get XI_Motion based scroll
events for regular mouse wheels. These are intended to be handled
as discrete scroll, so detect smooth scroll events that move by
exactly 1.0 in either direction.

When being fullscreen, and wanting to unfullscreen but not caring about
whether to go unmaximized or maximized (as this information is lost), if
the GdkToplevelLayout represents the full intended state, we won't be
able to do the right thing.
To avoid this issue, make the GdkToplevelLayout API intend based, where
if one e.g. doesn't call gdk_toplevel_set_maximized() with anything, the
backend will not attempt to change the maximized state.
This means we can also remove the old 'initially_maximized' and
'initially_fullscreen' fields from the private GtkWindow struct, as we
only deal with intents now.
This is a more reliable calling point than ::resume-events, and a
good one to schedule things so they happen on a frame clock in no
special phase (Thus still fixing the original issue at 80d4a08e30)
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3461
Those requests are received while dealing with the ::layout frame
clock phase, this has the unintended side effect of making the
frame clock "rewind" to handle ::flush-events again during this
frame, which delays everything and practically halves the frame
rate.
We do intend to make the motion events dispatches on the next frame,
so do this in an idle at a slightly lower priority than layout/draw,
so the ::flush-events phase is actually requested for the next frame.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3264
We don't need to go through the NSOpenGLContext for these.
We can just use the C API directly. It's also clearer what is using
CGLEnable() vs CGLSetParameter().
It was used by all surfaces to track 'is-mapped', but still part of the
GdkToplevelState, and is now replaced with a separate boolean in the
GdkSurface structure.
It also caused issues when a widget was unmapped, and due to that
unmapped a popover which hid its corresponding surface. When this
surface was hidden, it emitted a state change event, which would then go
back into GTK and queue a resize on popover widget, which would travel
back down to the widget that was originally unmapped, causing confusino
when doing future allocations.
To summarize, one should not hide widgets during allocation, and to
avoid this, make this new is-mapped boolean asynchronous when hiding a
surface, meaning the notification event for the changed mapped state
will be emitted in an idle callback. This avoids the above described
reentry issue.
We only called xdg_toplevel.(un)set_maximize() if the toplevel layout
changed, but this misses the case when the compositor had changed the
maximized state. Change it to call the xdg_toplevel request if either
the local layout changed, or if the layout differs from the current
state.
This fixes an issue where one couldn't unmaximize a window by double
clicking the titlebar that, had previously been maximized e.g. using a
keyboard binding.
Do the same for fullscreen.
This will sometimes mean a frame is skipped if a resize was requested
during the update phase of the frame dispatch. Not doing so can cause
trying to allocate a window smaller than the minimum size of the widget.
If compute_size() returns TRUE, the layout will not be propagated to
GTK. This will be used by the X11 backend to queue asynchronous resizes
that shouldn't yet allocate in GTK.
Not doing this means the next time the same surface is shown, if the
shadow size wasn't changed, it wouldn't be sent to the compositor, which
then would result in compositor deriving its own window geometry which
would include the shadow margin.
This fixes an issue where the file chooser dialog would grow each time
it opened.
The allocation of popups are part dependent of the allocation of the
root, which means the root must still be allocated when updates are
frozen, otherwise we'll try to allocate non-laid out popups.
This removes the GDK_CONFIGURE event and all related functions and data
types; it includes untested changes to the MacOSX, Win32 and Broadway
backends.
This removes the gdk_surface_set_shadow_width() function and related
vfuncs. The point here is that the shadow width and surface size can now
be communicated to GDK atomically, meaning it's possible to avoid
intermediate stages where the surface size includes the shadow, but
without the shadow width set, or the other way around.
GTK4 doesn't support arbitrary constraints when resizing a window (e.g.
steps, or aspect ratio), so we don't need to care about the result from
compute-size when doing interactive resizing.
This follows the trail of the Wayland backend in that GdkSurface changes
happen during the layout phase, and that a GDK_CONFIGURE no longer being
used to communicate the size changes of a surface; this now also uses
the layout signal on the GdkSurface.
If a surface scheduled a relayout, got frozen, and a layout phase
happened, then got unfrozen, it wouldn't see it's layout being
requested; avoid this race by remembering the pending phases until they
actually happened.
Reading the comment, it seems to be related being a window manager
decoration utility; this is not something GTK4 aims to handle, just drop
support for this.
By moving popup layout emission to the layout phase, the current
GdkPopup::poup-layout-changed signal has no value on its own as it'd be
ignored by GtkPopover.
Make the Wayland backend communicate the popup layout changes via the
common signal; but leave the rest intact until other backends catch up.
Put them in a anonymous struct, and separate the toplevel specific ones
into another anonymous struct inside the first one. Later popup related
fields will be added.
Don't have GtkRoot listen directly to the layout signal on the frame
clock, but let it pass through GdkSurface. This will allow GdkSurface to
be more involved in the layout phase.
Scheduling an update when frozen would reschedule when unfrozen; change
this to a generic pending phase enum, and use this for resrcheduling
paint and compute-size.
GdkSurface's are initialized to have the size 1x1, as otherwise we'd
receive an X11 error, would a corresponding X11 window be created.
This confuses the "saved size" mechanisms in the Wayland backend, as
treats 0 as uninitialized, and not 1.
Fix this simply not saving size that if it's smaller or equal than 1.
This will be handled between 'update' (which may trigger animation
ticks, CSS update, etc) and 'layout' which will allocate the widget
tree. It's meant to perform surface size computation, and is done
between these two phases in order to have an up to date state, and
letting the layout phase have an up to date size to layout in.
Concentrate state application to the start of a frame; this is to avoid
having GTK going back and forth between different state if so would
happen between two frames.
Queue it, and then wait for it to actually take effect, i.e. be
confirmed via a configure event from the compositor, before setting the
actual GdkSurface::state value.
The plan is to concencrate size computations as part of the frame clock
dispatch, meaning we shouldn't do it synchronously in the present()
function.
Still, in Wayland, and maybe elsewhere, it is done in the present()
function, e.g. when no state change was made, but this will eventually
be changed.
Mapping a surface under Wayland is an asynchronous process, where one
creates a surface and commits an initial state without having drawn
anything, then waiting for a configuration, which then is acknowledged
and content is painted and committed. Not until having received this
configuration is a surface actually mapped, so wait with setting the
mappedness until this.
We don't need the OpenGL view to be transparent if the window itself
is not transparent. This has the potential to speed up the compositing
of the GL view onto the NSWindow.
This fixes an issue where we would ignore events with Y delta
and no X delta while scrolling due to a typo when checking for
any delta.
This fixes deceleration of kinetic scrolling on the macOS backend.
Fixes#3418
We need to keep this consistent so that we can look things up
faster in other places. Therefore, just take the hit here and clear
the entire list ensuring prev/next poniters are cleared.
