Hi Clinton,<br>thanks a lot for the answer. I just would like to make an example.<br>Let's say that if I have a QVTKWidget in my QT interface and I press W on the keyword, that event is<br>detected by QT (first) which forward it to the QVTKWidget and then the interactor. is that right?<br><br>So I wonder, if I make QT managing the press of W first and then I would like QVTKWidget doing whatever is programmed to do,<br>would it be enough to add the correspondent handler in my QT Class (whatever it is? )<br><br>Thanks<br>Giancarlo<br><br><hr id="stopSpelling">Subject: Re: [vtkusers] QT and VTK interactor how to manage the signals<br>From: clinton@elemtech.com<br>Date: Tue, 2 Mar 2010 07:59:21 -0700<br>CC: vtkusers@vtk.org; qt-interest@trolltech.com<br>To: ilferraresebono@hotmail.it<br><br>
