Check whether the newly focused view is the same as the one currently
fullscreen on that output, or override redirect and don't unfullscreen
in these cases.
The output fullscreen surfaces are drawn in front of everything, without
consideration for view z-order.
If a view is brought to front, unset any fullscreen view that would
cover this view to make sure the view is visible.
It was broken because the damage extents were rotated about its
own center, not about the center of the surface.
This adds a new wlr_region_rotated_bounds that rotates regions.
This allows us to have only one code path (for both non-rotated
views and rotated views) and optimizes rendering for rotated
views.
This adds `wlr_xwayland_surface_is_unamanged`, to allow compositors more
fine grained control over XWayland focus.
A surface that is unmanaged should not receive focus, while other
windows that are just override redirect may want it (dmenu).
The way unamanged is determined is taken from wlc.
When double-clicking a maximized window title, so that the windows size is restored and the mouse pointer ends up _outside_ the window it becomes impossible to move windows.
The reason is that the button_count variable is not counted down if the mouse button is released outside the window, so the button_count remains incremented even after the button is released.
This patch adds a call to wlr_seat_pointer_notify_button if the mouse button is released outside the window.
(I am a complete noob to wlroots, so be kind...)
This will send the button pressed event to the client. This shouldn't
be a problem since sebsequent pointer movements are not sent to the
client. Thus the client will not for example start selecting text when
it is being resized using the compositor keybindigns.
When the cursor is not over a view, wlr_seat_pointer_notify_button is
not called. However, this function does the bookkeeping of the pointer
state with regards to the number of pressed buttons. Because this
function also sends updates to the focused view, it has been moved
down, after the focus has been updated.
The XWayland code for creating the cursor as well as creating the
surface itself are currently split up into two ifdef'ed sections in
`desktop_create()`. Move together these two sections in order to avoid
having multiple ifdefs as well as making it clearer that they do in fact
serve the same purpose of setting up the XWayland environment.
In case wlroots is not being compiled with XWayland support, we will not
have an xwayland surface in our roots view. While we make sure to pay
attention to that in some places, we are not being consistent and try to
access the xwayland surface in other places. Obviously, this leads to a
compiler error due to the field not being present.
Fix the issue by sprinkling in a few additional ifdefs where required.
