You get this information already. When a HippoCanvasBox is clicked you get a button-press-event and a mouse grab. When it is released you get button-release-event always. You need to call set_clickable on the box (IconButton should inherit from Box). You have to understand that you will always get a button-release-event even if the mouse is not over the button when released. set_clickable will call the activate signal for a real click (mouse is over the button when released). As far as I can tell we are still sending activate signals on mouse down. This is a bug in sugar for working with older canvases and we should start relying on mouse clicks. -- John (J5) Palmieri <[EMAIL PROTECTED]> _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
