<BR>
I'm developping a little interpreter Prolog with DrScheme and I've a problem with a mouse event. I've defined a frame in which I've also defined 2 panels. Each one contains an editor-canvas% and its text% associated.<BR>
<BR>
I'd like to open a little popup menu when the mouse right button is clicked (with items like "edit","copy","paste" ...). I tried in several ways but no one works ...<BR>
<BR>
I think something I don't understand something, but I've sure it should not be very difficult to implement.<BR>
<BR>
If somebody can help me. Thank you all.<BR>
