Filtering a TreeWidget

[soul_rebel]

Try to find the bottleneck using a profiler. There is no point in trying to optimize something if it is something else that greatly reduces the performance.

Well, unfortunately valgrind ist broken on FreeBSD right now, valgrind-devel works but crashes my application (which doesnt crash when being run alone).
Really weird and I know to little about Memory-Management-Internals to debug this.
I'll try to setup a Model-View for my data and ask in a new thread when I run into Problems.

Use gprof.
