[Qt-interest] Default Positioning of a Dialog

[Jake Colman]

Scott,

Yes, the parent is set correctly.  I've built the Qt Demo and Example
applications and verified that the "Find Files Dialog" example will
center over the launch window when executed using CDE as the WM but will
allow the WM to do explicit placement when executed under CDE.

Incidentally, I posted a question similar to this under a subject
heading related to the Qt/Motif extension.  At the time I though this
was specific to the Qt/Motif extension.  But I can replicate the same
problem using the Qt Demo.
