I'd like to write a Tkinter app which, given a class, pops up a window(s) with fields for each "attribute" of that class. The user could enter values for the attributes and on closing the window would be returned an instance of the class. The actual application I'm interested in writing would either have simple type attributes (int, string, etc.), or attributes using types already defined in a c-extension, although I'd prefer not to restrict the functionality to these requirements.
The only way I can imagine to do this is to create an instance of the class in question, and then start poking around in its attributes dictionary (initially just using dir). So firstly, if there is instead a way to do this without creating an instance I'd be interested. Secondly, the code won't know exactly how to initialise the class instance used to determinte the attributes. Do I need to make it a prerequesite that all instances can be created with no arguments ? Should I force/allow the user to pass an instance instead of a class ? Should I be using inspect.getargspec on the class __init__ method and then a loop with a try and a lot of except clauses, or is there a nicer way to do this ? Presumably the pickling code knows how do serialise/deserialise class instances but I'm not sure how I'd use this without already having a class instance to hand. Lastly, does such an app already exist ?
