I can't seem to keep the horizontal header from being selected when I select a single row in a QTableWidget. Example: How can I prevent the header from being selected too?

Suppose I have a commercial license for Qt (say, for 4.5.2 ), is it possible to reuse part of the QtCreator (say, version 2.0) source code to develop a completely proprietary software? I read the QtLicensing information, but it doesn't provide any information about QtCreator licensing. ...
Hi there. In my program I need to download 3-4 files simultaneously (from different servers which are quite slow). I'm aware of the solution involving python threads or qt threads, but I'm wondering: since it seems to be a quite common task, maybe there's a library which I feed with urls and simply receive the files? Thanks in advance! ...

I can add a QGraphicsView widget to my UI, but how do I then access the scene?

By this I mean, all clean up operations in the destructor have comple...
