Sorry for the spam, but now that I'm looking at the profiler's output again
in light of Paul and Marian's input, I think I've identified where I'll
need to make my improvements.
Thanks again for the help!

@William - there is no real noticeable difference between Debug and Release
modes and I haven't been able to extract anything of real use from the
profiler either (perhaps this is lack of experience on my part, I added a
screenshot of the the output here:

Yes, it can be statically linked, but trying to statically link two or more
QPA plugins is a dan

Indeed, views query model data very often. If, for example, data() is
even mildly slow the performance impact can be drastic. If you cannot
work around that directly, try to use caches (e.g. QCache,
QContiguousCache).

Hi All,
I can get the HWND of a running application by win API FindWindow, and can I
add a widget as its child to it in some way? or because there are so much
difference that the parent can't produce a such child?

Hi everyone,
I have just started playing with Qt’s MVC classes and have created a
hierarchical model to display in a QTreeView. Some of the nodes, however,
have a fair amount of children and when I expand these nodes (or, heaven
forbid, expandAll), the app hangs for a remarkably long time.
