What's for sure is that Konqueror itself doesn't do any of this, it's all done by KHTML.
But I fail to see why khtml would act differently in terms of text selection, between
being used in konqueror and being used in your app... Unless some mouse events get
filtered out, it should really just work the same. Are you sure it's the same version of
KHTML that you're using and that konq is using?
