On the left click on your objects, set a flag to True
Bind the left up event on the Canvas:
FC.EVT_LEFT_UP(Canvas, self.OnUp)
in that, set the flag to False
on the object, bind the enter event:
rect.Bind(FC.EVT_FC_ENTER_OBJECT, self.OnEnter)
if the flag is True -- you can set that as a selected object.
See enclosed example ;-)
