Main purpose is to reproduce a crash if the parent window gets
destroyed before the transient. For this the following key combo
can be used:
t: show transient
k: close parent window
q: quit application
This currently causes reliably a crash in Deleted::copyToDeleted for
the connect of the mainClients.
A small test application to use the Wayland Client classes. It opens
a fullscreen Shell surface and reacts to input events:
* q quits
* left click toggles the background color animation
* right click quits
