Q: xwayland overt Qt-compositor?

[jegde jedge]

Please forgive the 'user' post in a devel list.

I am porting a fundamentally Qt system but still need some X backward
compatability?

I am unclear of the Qt/X/Weston/Wayland interoperability.

Does the weston compositor work with Qt5 apps?
Can the Qt5-compositor run the Weston apps?
Will the Qt compositor host the xwayland server?

Am I asking the right questions?

Please help me understand the vision as it relates to future Qt and
past X both running on Wayland.
Respectfully
