BackgroundEnabled property

[Arcanor]

Default windows can use the following property, which I really like:

Code: Select all

wnd->setProperty("BackgroundEnabled", "false");

However, I've tried to find some way to do the same thing with FrameWindows and Listboxes and I can't figure it out.

Why is the BackgroundEnabled property not settable for these important window types? Or is there a way to do this that I've missed?

Thanks in advance!
