Maybe this is what you are looking for: Set the /button_events keyword
when creating the draw widget (or set the /draw_button_events to
widget_control later). Then the draw widget will create events when you
click your mouse into it. The pixel coordinates are available via
event.x and event.y. If you want to distinguish between left and right
mouse button, press and release, etc., read "Widget Events Returned by
Draw Widgets" in the online help for "widget_draw".
