Re: Linux Weekly News quotes answer to Bruce's mail about Wayland

[Dimitris Anogiatis <dosida@xxxxxxxxx>]

Theoretical question.

Would we be able to create the main window as completely transparent and
turn the application forms as sub-windows?
That way we would be able to have some sort of a coordinate system for our
apps.

But then the following questions arise:

1) What happens when there's more than one monitors attached to our
hardware setups?
2) Would we lose any functionality if we implement something like that?
3) Can we create sub-windows through Qt or GTK+ in 3.19?

Regards,
Dimitris
