This typedef was not used in any public APIs, and is
only used in the MacOS backend. It is not worth preserving
as public API, move it to the only user.
This implements the basics for a GdkGLContext on macOS. Currently, rendering
only is fully working for the GskCairoRenderer case where we read back pixels
into a cairo surface for rendering. More work on synchronization is required for
the GL on GskGLRenderer case.
When we attempt to render a surface itself with GL, the context will ensure that
the new GdkMacosGLView is placed within the NSWindow. In other cases, we
use a dummy NSView and NSWindow for backing the NSOpenGLContext to
ensure that we can get accelerated drawing.
This gets GtkGLArea working when running with GSK_RENDERER=cairo.
This helps a situation where the window contents has not changed
in time for a drawing. Setting the texture gravity helps that side or
corner to be less jittery while moving.
Ideally, we can get to a point where we are synchronized and keeping
up with drawing fast enough to not need this. That may require some
work to drive frame clocks from drawRect: though.
The current code was marking queued events as flushed,
but left them in the queue. That doesn't make sense to
me - we should deliver all events we have before we
reach the paint phase of the frame cycle.
GLDEBUGPROC callback is defined with APIENTRY which is a windows
specific calling convention. That macro expands to nothing when building
on other platforms.
Fixes: #3268.
Call SetCapture() explcitly for the (new) modal window so that we make the
modal window respond to mouse input, and also call SetCapture() to the parent
of the transient window that we are destroying so that mouse input capture is
returned to the parent window.
This attempts to fix the following:
* Upon creating a new modal window, the new modal window does not receive
pointer input unless one switches to another program and back
* Upon closing a transient window, the parent window that activated the
transient window does not receive pointer input unless one switches to
another and back
This reverts commit fc2008f2.
Turns out, we *don't* have code to maintain Z-order. Restacking
code is not doint that, it just enforces a few weird Z-order-related
behaviours.
Make sure that we get the state of the modal window properly, and send out the
corresponding notification signals.
This will ensure that we do not try to activate windows that should have become
inactivated due to it opening modal windows and render the program unresponsive
because we are not activating the correct window that is due to receive user
input.
The 'has_uncommitted_ack_configure' state was added to make sure we're
responding to 'xdg_surface.configure' events with
'xdg_surface.ack_configure' requests, as is necessary according to spec.
What we didn't do was to clear this state when hiding, meaning that if
we hid the surface after a configure event, but before the frame
finished and we processed the 'has_uncommitted_ack_configure', we'd try
to acknowledge the surface configuration after having destroyed the
surface.
Closes: #3262
This was incorrectly reporting the toplevel surface instead of the
popup surface that was placed above it. This fixes event delivery
to popups for selecting menu items and more.
This fix is correct and fixes:
1) GL textures being upside down in the inspector. They are getting
downloaded because they've been created in a different GL context
2) GL textures being upside down in the cairo renderer (same reason)
However, it breaks the testsuite. We do the flipping via the projection
matrix, but most of the shaders don't care about that.
The GdkWayland API takes generic GDK types and performs a run time
check, which means we need to properly annotate the actual expected
type in order to have methods recognised as such.
When querying a device, we need to ensure we are providing coordinates
in the coordinate system of the surface. Further, we need to actually
provide the button and keyboard state.
This fixes some issues related to dragging scrollbars and selecting list
box rows more reliably.

No users of gdk_display_peek_event, gdk_display_has_pending
_gdk_display_event_data_copy or _gdk_display_event_data_free,
so drop all of these, and related vfuncs.
Go back to installing our debug message callback
unconditionally if G_ENABLE_CONSISTENCY_CHECKS is
defined, and allow opting into it using GDK_DEBUG=gl-debug
otherwise.
Prevents GDK Popups from stealing focus from the parent window when
using Server Side Decorations on win32.
It uses `ShowWindow` and the `SW_SHOWNOACTIVATE` flag.
When using the saved size because the compositor
told us to, we were forgetting to readd the margins.
The visible symptom of this was the window getting
smaller every time we went to tiled state and back.
Don't remember the surface size when we are in tiled
state either. This matches the 'fixed_size' condition
in gdk_wayland_surface_configure_toplevel.
This change fixes an issue where moving a window first
to tiled, then to maximized state and back would lead
to the unmaximized window having the tiled dimensions.
We should not emit configure events before we are realized - size
changes at this point are not relevant.
This gets rid of a mysterious emission of GdkSurface::size-changed
with a size of 52x52, that is happening when GtkWindow sets the
shadow_width before the window is mapped.
Always install the debug message callback when we can
and GDK_DEBUG=gl-debug is specified. Previously, we
were only installing the callback when the build was
a non-optimized debug build.
If all your callers already initialize the array element as needed,
then we don't need to memset it to zero first.
This is pretty useful for the snapshot state stack, because due
to the per-node-type data area the elements on the stack are
quite large, but often a lot of it is not used.
This inlines the splice and reserver GdkArray calls. These are
typically only called from the gdk_array_(append/set_size) functions
anyway, and inlining the caller means we can constant propagate the
constant arguments in those calls. Its hard to get exact numbers, but
in fishbowl i noticed a significant decrease in the time spent in
the array code when pushing and poping states.
There is nothing really special about this code, its just a helper for
uploading pixel data to opengl, and we're not really in the business
of doing opengl-specific helper functions.
Do custom uploads rather than using gdk_cairo_surface_upload_to_gl(),
because this way we avoids a roundtrip (memcpy and possibly conversion)
to the cairo image surface format.
The gdk-pixbuf non-rgba format can be directly uploaded without
conversion.
The rgba format needs alpha premultiplication though, which is not
supported by GL during upload.
GLES doesn't support the GL_BGRA + GL_UNSIGNED_INT_24_8 hack that
we use on desktop OpenGL to upload textures directly in the cairo
pixel format. This adds the required conversions to all the places
that currently need it.
We also add a data_format to the internal gdk_gl_context_upload_texture()
function to make it clearer what the format are. Currently it is always
the cairo image surface format, but eventually we want to support other
formats so that we can avoid some of the unnecessary conversions we do.
Also, the current gdk_gl_context_upload_texture() code always converts
to a cairo format and uploads that like we did before. Later commits
will allow this to use other upload formats that gl supports to avoid
conversions.
This is the default OpenGL format, and in fact the only pixel format
that GLES supports uploading as. Actually, the premultiplied part is
really just about how we use the textures, but all textures in GTK
are premultiplied.
Most of the surface api we have in the Wayland backend
only makes sense for toplevels, so reshuffle things to
take a GdkToplevel instead of a GdkSurface.
Update all callers and the docs.
We must wl_surface.commit after xdg_surface.ack_configure to make it
have an effect. We failed to do so when a configure event didn't result
in new updates, so make sure we fall back on an simple
wl_surface.commit if there was no new actual frame painted.
Closes: #2910
In order to make the cairo renderer/context behave more similar to how
the OpenGL and Vulkan renderer/context behaves, request a frame callback
and commit in the end frame vfunc.
This means the end frame vfunc in cairo does
* attach buffer
* request frame callback
* sync surface state
* commit
Where as e.g. the OpenGL version of the same flow does
* attach buffer
* request frame callback
* sync surface state
* eglSwapBuffers()
where eglSwapBuffers() indirectly calls wl_surface_commit().
Since the changes to GDK to use surface subtypes, CSD windows were
broken because we did not set the window styles properly. Fix this by
first acquiring whether decorations are used by the GtkWindow, and based
on that result we set the decorations that we want to use accordingly
and so apply them.
Thanks to Matt Jakeman for investigating into the issue and providing
pointers to a proposed fix.
Fixes issue #3157, besides the part where window sizes are not correct
since that is likely caused a separate issue.
Don't pass 0x0 as size when calling gdk_surface_new().
The Wayland backend takes us literally, and we end
up with a surface that (temporarily) has these
dimensions, confusing other APIs that we pass the
size to, such as Vulkan.
We end up with a surface that has size 0x0 at the
time we create the Vulkan context, and that is a
size that Vulkan doesn't like, so ensure we request
at least 1x1.
Fixes: #3147
When using the gdk_display_close(), the handle to the Wayland compositor was not released. This could cause the consumption of all available handles, preventing other processes from accessing the display.
Fixing this by calling wl_display_disconnect() when releasing the GdkWaylandDisplay object.

We want to ensure that the pointer position is reflected
when widget geometry changes, so add a function that tells
GDK "please create a motion event at the current position
on this surface, if one doesn't happen already".
Handle both these settings, and the older settings-daemon ones for
backwards compatibility. The keys are already checked for existence
in the schema, so it will just use the existing ones.
Prefer this location, but also look for the old location in
settings-daemon for backwards compatibility. This applies to both
direct settings lookups and via the settings portal.
If some node is fully outside the clip region we don't send it to the daemon.
This helps a lot in how much data we send for scrolling viewports.
However, sending partial trees makes node reuse a bit more tricky. We
can't save for reuse any node that could possibly clip different depending on
the clip region, as that could be different next frame. So, unless the
node is fully contained in the current clip (and we thus know it is not
parial) we don't allow reusing that next frame.
This fixes#3086
A year ago, we make this function not return the child
surface anymore. But the information whether the device
is actually over the surface is still useful, and we
should not loose it.
If alpha is 255, we use rgb() instead of rgba(), not if alpha is 0.
This makes the title bar gradient go from fully transparent to blue
rather than black to blue..
When we send an anchor rectangle with a width or
height of 0, mutter reponds with "Invalid anchor
rectangle size". So, don't do that.
This was seen as sudden disappearance of gtk4-demo
when you click the fishbowl benchmark all the way
through to the menubuttons.
Fixes: #3027
We might break the loop early, e.g. if we're unmapped before the round
trip finishes, and to avoid the callback to write to invalid stack
memory, destroy the callback so it won't be invoked.
Fixes: #3026
GTK will not up front know how to correctly calculate a size, since it
will not be able to reliably predict the constraints that may exist
where it will be mapped.
Thus, to handle this, calculate the size of the toplevel by having GDK
emitting a signal called 'compute-size' that will contain information
needed for computing a toplevel window size.
This signal may be emitted at any time, e.g. during
gdk_toplevel_present(), or spontaneously if constraints change.
This also drops the max size from the toplevel layout, while moving the
min size from the toplevel layout struct to the struct passed via the
signal,
This needs changes to a test case where we make sure we process
GDK_CONFIGURE etc, which means we also needs to show the window and
process all pending events in the test-focus-chain test case.
gdk_gl_context_has_framebuffer_blit() and gdk_gl_context_has_frame_terminator()
were only used by by GDK/Win32, and they do not provide performance advantages
in GTK master, so clean up the code a bit by dropping them.
Use gdk_surface_get_geometry() to get the correct x and y coordinates of the
window that we are resizing, so that the window does not reposition itself
automatically at the top-left corner at resizing as we to used hard-code the x
and y coordinates to 0.
By doing so, we ensure that resizes of windows will work on Vulkan renderer, by
first calling gdk_win32_surface_handle_queued_move_resize() before we proceed
as usual
Use the shared function that was added in the previous commit, to simplify
things.
Also make gdk_win32_surface_get_queued_window_rect() and
gdk_win32_surface_apply_queued_move_resize() back into static functions, since
they are now used only by the code in gdksurface-win32.c
Since we need to deal with queued moves and resizes in the Cairo, GL and Vulkan
draw contexts, and the logic involved in all three of these are largely
similar, add a function gdk_win32_surface_handle_queued_move_resize() that will
handle this, which will be shared between these three types of draw contexts.
Move gdk_win32_surface_get_queued_window_rect() and
gdk_win32_surface_apply_queued_move_resize() to gdksurface-win32.c, since these
functions are not only used for Cairo draw contexts, but is also used for GL
draw contexts, and will be used for Vulkan draw contexts.
Don't get the default display when we compute the Aerosnap region, but instead
get it from the underlying GdkSurface that we are using for the computation.
Also, don't unref the monitors that we obtain from the display in the wrong
place, which was why we had crashes whenever we triggered AeroSnap code (and we
are actually not supposed to do that as they are owned by the GdkDisplay that
is owned by the GdkSurface we are using), and this will eliminate lots of
criticals that are spewed as a result.
