How do I reconize a Mouse Click inside a canvas?

[Eric Klumpp]

Hello,

I recently used the canvas !
To use the mousePressEvent, I do as it is rapidely explained in the Qt 
help for QCanvasView : I have done my own sub-class of QCanvasView that 
I named TView_Canvas, and I added the protected method declaration 
"virtual void contentsMousePressEvent(QMouseEvent* e)", and its 
definition as explained.

My project is a SDI, but emit a signal in this method should certainly 
resolve your problem !

Eric

PS : I use Qt 2.3.1, it is perhaps different on an other version
