You are right, self would have evaluated to a boolean True, so what was happening was the dialog was being shown after being created, and then your show() line was being called again, and then the dialog was being released. > BTW, we've been trying to figure how to use functions based on the way > they are presented in the API documentation.

Correct. Python has positional and keyword arguments, and either can have default values. The act of giving a default value makes it have both positional and keyword argument behavior. So, show is the second argument (argument number 1, given python's zero-based indexing). If you don't pass a second argument, show will get the default value of False. > and how would we know from the documentation, that a third parameter could > be "parent=self"? You wouldn't. This createForm() function simply passes any additional positional (*args) and keyword (**args) arguments up to the constructor of the class, which accepts all kinds of arguments depending on the class in question. So, you'd have to know that the dialog class (and all dabo ui classes) accept a parent argument. Once you've used Dabo for a while, you know this implicitly. The confusing thing here is that the parent arg is in the second position in all dabo ui classes, but in the third position for the createForm() function. > (and is that an "*arg" or a "**kwarg"?) * sends a tuple of positional arguments, and ** sends a dict of keyword arguments.
