This will be used by a new event filter, added only when running as a Wayland
client, to force creating the obs_display instance even when not exposed.
The sizeChanged callback is connected to the screenChanged signal,
and evidently the naming doesn't match. Rename the callback to
match the signal name.
Right after showing the OBSQTDisplay widget, it may happen that a
wl_surface is not yet created and attached to the window. When this
happens, creating the OBS display results in a crash.
Make QTToGSWindow return a boolean, indicating success or failure, and
don't create the OBS display on failure.
When a window is made invisible, then visible again, the
obs_display is reused. Turns out, QT destroys the wl_surface
associated with the previewer on Wayland. However, the EGL
surface created on top of this wl_surface is not, and any
attempt to attach a new buffer to it will crash OBS.
Destroy the obs_display when becoming invisible, and when
running as a Wayland client. Also nullify the display
variable on destruction, to avoid subclasses double-freeing
the obs display.
On Wayland, we want to query the window's underlying
platform for the Wayland surface, instead of foolishly
retrieving the X11 display.
Pass QWindow instead of WId directly, and set the surface
as the platform data on Wayland systems.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
