the right side of an assignment is always evaluated before it is assigned, so
self.button["command"] = self.getPath(t)
will call self.getPath(t) and then assign the return value to button["command"].
quite obvious, if you think about it, right ?
the easiest way to fix this is to add a local function that calls getPath, and
use that as the button callback:
def callback():
self.getPath(t)
self.button["command"] = callback
(if you want, you can inline the getPath code in the callback).
