Re: Creating dynamic window

Okay, answering my own question:

I discovered the noresource.py in the samples
directory and followed it to create a textfield at run
time.  After that, I went a little further and setup a
button on the fly.  In fact, I can have a function
on_Button1_mouseClick which in turn create another
button so that when I click on button1, it creates yet
another button.  All works.  See attached.

However, how do I create the event handler on the fly?
 In my sample, I pre-defined the routine
on_Button1_mouseClick but that's not going to work for
the general case.

So, how can I define the event handler on the fly?
