I'm trying to generate some events in Tkinter but it doesn't seem to be working
the way I expected. Here's an example of what I'm trying to do...
def click():
print 'click'
from Tkinter import *
top=Tk()
b=Button(top, text='Hit me', command=click)
b.event_generate('<Button-1>', x=0, y=0)
b.event_generate('<ButtonRelease-1>', x=0, y=0)
The appearance of the button changes after the <Button-1> event (to depressed),
and again after the <ButtonRelease-1> event (to normal again), but the
associated button command (the click function) is not called. If I bind a
function for the event to the button using the bind method, it gets called, but
I really need the associated command to get called too.
Also, I tried doing this with a Pmw.ScrolledListBox with an associated
dblclickcommand, so I tried to generate <Double-Button-1> and
<Double-ButtonRelease-1> events, but to my surprise, I received the following
error message for both cases:
_tkinter.TclError: Double or Triple modifier not allowed
These problems are getting in the way of my attempt to automate GUI testing
with Tk. Am I missing something?
(Ok, I really don't need the first case, because I can simple call the button's
invoke method. But in the second case, the associated action is only invoked
via the double click action.)
