How do I reconize a Mouse Click inside a canvas?

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