This registers the wl_scaler global object and lets clients create
wl_surface_scaler objects for surfaces. wl_surface_scaler.set is not
implemented so this doesn't really do anything useful yet.
|
|
Add cropping and scaling to wl_surface.
Add a global factory interface wl_scaler, which creates
wl_scaler_surface objects tied to a given wl_surface. The
wl_scaler_surface object can be used to set a cropping and scaling
transformation to change how a wl_buffer maps to wl_surface contents.
Changes in v2:
Take into account buffer_transform and buffer_scale, and try to explain
more clearly how the coordinate transformations work and what their
order is. Add, that crop and scale state is double-buffered. Explain
missing dst_x, dst_y. Clarify that undefined content still is some
content, but NULL buffer implies no content nor size.
Changes in v3:
Disallow zero values for dst_width and dst_height.
Open issues:
Should this be a separate interface like here, or just a wl_surface
request?
If we keep this as a separate interface, rename wl_surface_scaler to
wl_viewport.

Surfaces that are created by clients get their size automatically updated
by the attach/commit. Surfaces created directly by shells (such as black
surfaces) sometimes need to be manually resized. This function allows you
to do that while being somewhat less messy than messing with the internals
of weston_surface manually.

When a view is moved to another output because its current output was
unplugged, remove the fullscreen and maximized state.
|
|
If the saved position for a fullscreen or maximized output view is in an
output that has been unplugged, the coordinates don't make sense
anymore. In that case, invalidate them and use the initial position
algorithm when changing them back to the basic state.

Previously, if a pointer was inside an output that was unplugged, it
could potentialy end up outside any valid output forever. With this
patch, the pointer is moved to the "closest" output to the pointer.
|
|
Set a flag when an output is being destroyed and use that to avoid
repainting. This allows functions that schedule an output repaint to
be called when the output is being destroyed without causing the
compositor to crash.
|
|
Use the output destroy signal to move the views in the event the output
was unplugged.

Previously, when an output was moved due to another output being
unplugged, the views on the first output would remain in the same
position.
This patch adds an output_move signal that the views listen too in
order to repostion themselves in the event of an unplug.

The call to weston_output_move() when creating the output is
unnecessary. That is already called by wesotn_output_init().
|
|
Instead of having the backends move the remaining outputs when one is
destroyed, let the core compositor deal with that.

When destroying ouputs, they would sometimes be removed before the call
to weston_output_destory() and sometimes after, depending on the
backend. Now the output is remove withing that function so the behavior
is standard across all backends.
|
|
Instead of terminating the compositor, destroy the output whose close
button was clicked and move the other outputs, as is done in the drm
backend.

We now no longer add joysticks at all. They show up as absolute motion
devices without has_button, so we don't add them as a pointer. We may add
a keyboard for the keyboard-style keys, but that's fine. With the previous
commit, we no longer generate spurious absolute pointer motion for the abs
axes.
https://bugs.freedesktop.org/show_bug.cgi?id=71687
|
|
Some joysticks have certain buttons that acts keyboard keys. As such,
we'll reconize them as keyboards but not pointers. In that case, don't
send pointer motion events when we get absolute joystick events.
|
|
This rule triggers for devices with an ABS_X/Y evaluators and no
keyboard or multitouch events. There is no way we would ever add such
a device as a pointer, keyboard or touch device anyway. A pointer
device requires has_button (in which case the !has_key condtion would
fail); a keyboard device would also mean !has_key is false and a touch
screen device implies that !device->is_mt is false.
|
|
We now keep all the configuration intermediate results inside
evdev_configure_device() and the result is device->seat_caps.
|
|
|
|
|
|
|
|
We split up has_abs into plain ABS_X/Y and MT events, but this shouldn't
introduce any logic changes.
|
|
This is only used inside evdev_configure_device() and we now use a local
has_rel flag instead.
|
|
We split the device probing and idenfication somewhat arbitrarily between
these two functions. This commit combines them into one. Return of -1
indicates error, 0 success, but succesful probing can return a device
with device->caps == 0, which means we don't handle the device.

compositor.h must not define a 'static_assert' macro, since that
conflicts with the new 'static_assert' in the standard and breaks
the build.
|

Ignore the new stacking demo...

It's the GO FASTER option.

This is not a benchmark.

This adds a test that tries to simulate a simple game loop that would
be like this:
while (1) {
draw_something();
eglSwapBuffers();
}
In this case the test is relying on eglSwapBuffers to throttle to a
sensible frame rate.
The test then verifies that only 2 EGL buffers are used. This is done
via a new request and event in the wayland-test protocol.
Currently this causes 3 buffers to be created because the release
event generated by the swap buffers is not processed by Mesa until it
blocks for the frame complete event in the next swap buffers call, but
that is too late.
This can be fixed in Mesa by issuing a sync request after the swap
buffers and blocking on it before deciding whether to allocate a new
buffer.

The device may not have a resource for the client yet, but install
the listeners nevertheless.

The surface type now no longer changes and we track pending state changes in
next_state. Instead of testing type != next_type to detect changes in
state, we just look at state_changed.

An xwayland surface corresponds to a override-redirect window under X,
which is typically a menu or a popup window. They typically appear
with a keyboard and mouse grab and by nature of being override-redirect
these window can appear anywhere on screen and in the stack.
We need to resort to heuristics to decide where to place the
override-redirect in our surface stack, and for now we'll just put it on
top of everything. That's going to be correct for almost all cases of
clicking to open a menu, but we can revisit and refine if we run into
a case that needs better handling.
|
|
This is used from wl_shell and xwayland and we need to make sure
xwayland also gets this behavior.
|
|
Just as for set_maximized() we can move the setting of the fullscreen and
state_changed flags into the common set_fullscreen() function. This
function is also used from the xwayland wm to set fullscreen windows, and
with this change that now works again.
|
|
We can set the maximized and state_changed flags in set_maximized(),
which is shared between shell_surface_set_maximized() and
xdg_surface_set_maximized().
|
|
Yes, perhaps this should be more automatic...
|
|
Fixes the crash from alt+tab when there's a fullscreen surface.
|
|
Since internally there's no more SHELL_SURFACE_FULLSCREEN and
SHELL_SURFACE_MAXIMIZED, the surface must be set to
SHELL_SURFACE_TOPLEVEL on the respective functions.
This fixes the bug when clients start already in fullscreen mode. In
that case, they aren't set first to toplevel, and then change to
fullscreen. They are set as fullscreen directly, not receiving the
SHELL_SURFACE_TOPLEVEL type on the set_fullscreen function.
|

The gl renderer typically repaints everything since we don't have
EGL_buffer_age under X, but the pixman renderer carefully only repaints
damaged regions. So to actually repaint anything with the pixman
renderer, we need to damage the output.
https://bugs.freedesktop.org/show_bug.cgi?id=72351
|
|
This should fix the surface not going back to its original position
after unsetting fullscreen or maximized states.

This adds a -b option to force the nested compositor example to use
the old blit renderer even if the appropriate extensions are
available.
|
|
Adds a second renderer implementation to the nested compositor example
that creates a subsurface for each of the client's surfaces. The
client buffers are directly attached to the subsurface using the
EGL_WL_create_wayland_buffer_from_image extension instead of blitting
them in the redraw_handler.
The new renderer is always used if the parent compositor supports the
wl_subcompositor protocol and the EGL extension is available.
Otherwise it will fall back to the blit renderer.
|
|
Adds a simple accessor for the wl_subsurface for widgets created with
window_add_subsurface.
|
|
Eventually the nested compositor example will want to be able to cope
with either rendering as it does now with a blit to an intermediate
surface or by attaching the client buffers directly to a subsurface
without copying. This patch moves the code that is specific to the
blitting mechanism into a separate set of functions with a vtable to
make it easier to add the second way of rendering in a later patch.
|

Previously the frame callback list was tracked as part of the global
compositor state. This patch moves the list to be part of the surface
state like it is in Weston. The frame callback now iterates the list
of surfaces to flush all of the callbacks. This change will be useful
when the example is converted to use subsurfaces so that it can have a
separate frame callback for the subsurface and flush the list for an
individual client surface rather than flushing globally.
|
|
The nested compositor example now responds to damage requests and
tracks them in the pending buffer state. This isn't currently used for
anything and it is immediately discarded when the surface is commited
but it will be used later when the example is converted to use
subsurfaces.
|
|
The buffer and frame callback state on the surfaces in the nested
compositor example are now double-buffered so that they only take
effect when the commit request is received. This doesn't really make
much difference for the current state that the example has but it will
be useful when more state is added in later patches.
|
|
This copies the buffer reference busy count implementation from Weston
to the nested compositor example and adds an internal nested_buffer
struct that we could eventually use to attach data. This will be
useful to adapt the example to use subsurfaces so that we can attach
our compositor-side buffer to the resource.
