[PyQt] Managing variables accross a multiple module GUI

[Denni]

Note one of things I have found with the GUI is that it ought to be Class-ified a lot which is to say building sub-classes to handle various sub-elements is a lot cleaner and easier to maintain than having all the functionality within a single Class which seems to be how PyQt was designed -- so inheritance and re-classing things is often a very solid answer to making the code easier to read/maintain as well as necessary in order to do certain things
