This will bind to leftmouse-down, which is different from clicking a
button. If you want to simulate a real button click with event
bindings, you will need to set a flag on ButtonPress-1, then in
ButtonRelease-1 check for the flag, check to see if the mouse is
within the button, and then activate your callback.
Something else you could try (which I haven't tested) --- instead of
box.cancel.bind, do box.cancel.config(command= ...).

Here's what I got from a little experimentation and print
box.cancel.bind.__doc__.
>>> def bar(action):
... print action
>>> import Tix
>>> root = Tix.Tk()
>>> box = Tix.ExFileSelectBox(root)
>>> box.pack()
>>> box.cancel.bind("", bar)
'-1212073588bar'
>>>
If you have a look at box.cancel.bind.__doc__ you can find everything
you can put into the SEQUENCE string "" is left mouse
click.

[Tutor] Tix: binding
I am looking at Tix and I am stuck with what seems to be a simple problem: I want to bind the cancel buttom of a ExFileSelectBox to a routine in my class, but can not make it work. I guess the problem is the same for any binding of tix sub-widgets, so if someone could send some sample code. >>> import Tix >>> root = Tix.Tk() >>> box = Tix.ExFileSelectBox(root) >>> print box.subwidget(name='cancel') .11827520.bf.cancel#so the sub-widget cancel buttom is there But how to bind it ? >>> box.cancel(command = lambda a,b : a+b ) Traceback (most recent call last): File "", line 1, in ? box.cancel(command = lambda a,b : a+b ) AttributeError: _dummyButton instance has no __call__ method Or >>> box.subwidget(name='cancel' , command = lambda a,b : a+b ) Traceback (most recent call last): File "", line 1, in ? box.subwidget(name='cancel' , command = lambda a,b : a+b ) TypeError: subwidget() got an unexpected keyword argument 'command' So, it seems I can not bind to command, but what then ? >From the Tix docu I thought the buttoms are normal Tkinter widgets ? -- Harm ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
