That's basically what the patch I posted does. The problem is that the
base class doesn't have any knowledge of what controls are on an
instantiated dialogue, or how to test if they've been changed from
whatever the default is (for new objects) or from whatever pgObject
derived object exists for edits.
The only way I can see to do this is to write a function for each
individual dialogue that can compare the values of each control to the
defaults or an existing object - pretty similar to what CheckChange()
already does - the difference being that it is validating as well.
