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.
The keycode and modifier (state) parameters are in the wrong order
for gdk_key_event_new() in the gdk win32 backend, which causes
key up/down events to be populated incorrectly.
This isn't done automatically for us, so we need to synthesize it in
our hide helper.
With this commit, we properly re-focus the new main/key window after
we have closed a transient-for window.
We need to re-attach to the transient-for window whenever we present or
we risk getting placed behind the window by the display server. Apparently
that setting does not persist across a hide of the NSWindow.
since http RFC state that the header names should be processed case in-sensitive, broadway should not rely on the actual case. E.g. the go-language libraries tend to rewrite the header, which cause problems with e.g. Caddy

The use of volatile was incorrect in GLib and has been that way for
a long time. Recently however that has changed, and this makes GTK
follow suit to avoid using volatile in the type registration.
See also: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719
Combined with the above merge request for GLib, this fixes a large
number of compilation warnings when using Clang.
Use the set_minimized method of the xdg_toplevel
interface to implement minimization as well as possible.
It is not possible, since there is no corresponding
state that we could use to update our surface state,
but in practice, it works well enough.

This commit fix the warning:
../gdk/wayland/gdkdisplay-wayland.c:1079: Warning: GdkWayland: gdk_wayland_display_set_cursor_theme: unknown parameter 'name' in documentation comment, should be 'theme'
Currently GTK can be built with G_ENABLE_DEBUG which enables various debug code and parsing
of those env vars, or without, which instead of parsing them prints a warning if they are set.
While building with G_ENABLE_DEBUG isn't strictly needed it's the only way to make GTK_DEBUG=interactive work,
which is a nice thing to have always.
This enables parsing of those env vars in any case and allows specific values being marked as also
available when not built with G_ENABLE_DEBUG (interactive for example). If not built with G_ENABLE_DEBUG
then all unavailable values will be marked as such in the help output and a note is added that
GTK needs to be built with G_ENABLE_DEBUG to use them, which should help discoverability.
In gdkdevice-win32.c we are interested in knowing which window
receives mouse input at a specific location.
Only WindowFromPoint is the right API for the task, other API's
(such as (Real)ChildWindowFromPoint(Ex)) have shortcomings because
they are really designed for other purposes. For example, only
WindowFromPoint is able to look through transparent layered windows.
So even if we want to find a direct child we have to use
WindowFromPoint and then walk up the hierarchy.

Once we figure out what is going on with textures, changes are we'll be
able to let this stay a zero rect. But that is still a bit up in the air right now.
When we close grabbing popups due to an outside
click, check at each level if the click is still
outside. This makes closing the nested popover
menu in the popover on page 3 of widget-factory
work as expected, when you click the menubutton
again.
When an event happens on a non-grabbing popup that hangs off
a grabbing popup, don't trigger the autohide. This makes touch
text handles work inside the popover on page 3 of widget-factory.
We can just call gdk_surface_invalidate_rect here
like we do elsewhere in gdk, and I'm a bit uncertain
about the current code that adds an empty update
region.
The Cairo implementation for the Macos backend uses a toplevel
window with full transparency and a series of NSView to create opaque
regions. This improves compositor performance because it allows the
display server to avoid costly blends.
However, we want to ensure we clip better when exposing the
transparent region so that we only expose the shadows/corners as
necessary.
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,

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..
