[Qt-interest] dragging a picture

[Christoph Keller]

Hi,

you could reimplement the QWidget's mouseMoveEvent(), mousePressEvent() 
and mouseReleaseEvent().

The pressEvent remembers the point where you've clicked. The 
mouseMoveEvent scales the image by the y-distance of the cursor to this 
point. The releaseEvent stops the operation.

Greetings,
Christoph
