Tkinter users,
I have a Tkinter app that redraws objects on a canvas, about 10 times a
second. It doesn't reuse the drawn objects, it just draws and deletes.
In order to make it so that we can click on these objects, we have code like:
self.simulator.canvas.tag_bind("robot-%s" % self.name, "<B1-Motion>",
func=lambda event,robot=self:self.mouse_event(event, "motion", robot))
for each object (a robot). First, is there a better way than doing this
after every object creation?
One problem with this method is that it appears to cause a memory leak.
Trying to unbind these, like:
self.simulator.canvas.unbind_all("<B1-Motion>")
or this method:
self.simulator.canvas.tag_unbind("robot-%s" % self.name, "<B1-Motion>")
doesn't seem to help. Any ideas on a better way, or how to stop the memory
leak?
Thanks!
-Doug
