[Qt-interest] Thoughts about QGestures

[Guido Seifert]

Hi.
You told me how to create my own gesture recognizer. Yes, I can do that.
But this is far from an equivalent to a QPanGesture. You left out the
interesting part. The pattern recognition in the list of points you 
can get from the mouse movement between the mouse press and mouse release. ;-)
