Facing problem with Q3Canvas

[Kapil]

hi.

are u deriving the class DiagramView from Q3CanvasView...

For me something like this works pretty fine...

void CanvasMouse::contentsMousePressEvent(QMouseEvent* e)
{
               if(e->button() == Qt::LeftButton)
               {
                    QPoint pPress = inverseWorldMatrix().map(e->pos());
               }
}

void CanvasMouse::contentsMousePressEvent(QMouseEvent* e)
{
               if(e->button() == Qt::LeftButton)
               {
                    QPoint pPress = inverseWorldMatrix().map(e->pos());
               }
}

To copy to clipboard, switch view to plain text mode 

though it seems a crude method but try something like this that try to call the mouse events in the class where u have created the canvas... where u have set its size and its view... it might help...
