You could see the Qt source code to check what this does for the
Windows part of the solution.
Here is another way of doing it under Windows - as coded in tiOPF.
I've never used this myself, so don't really know the code at all,
just know it is there.
I had some code for X11, but couldn't find it now - it might be on my
work PC. If I find it, I'll post it here.
Thanks for that. Presumably some of the portability issues are due to
the difficulty of manipulating bitmaps, hence TLazIntfImage etc.
Looking back through something I wrote in Delphi I see I used
TCustomForm.GetFormImage. Bug 11292 implies this is in 0.9.26 for Win32
and GTK2, position with other widget sets uncertain.
I might take a look at this later but since it turns out to be
non-trivial it would probably be wise if I concentrated on core
functionality first.
