And one more step, use that panel (the parent of the message and the
tree windows) as the window that is put in the splitter. In other
words, you are adding an extra layer in between the splitter and the
message/tree widgets, and that new layer will be managed by the splitter
and it will in turn manage the message or tree widgets.
I can't get this working at all.. I've followed the steps above plus a bunch of
different variations but to no avail. I've simplified my code just down to the
bits needed to show what I'm trying to do and included it below. I hope this
helps show what I'm doing wrong
