[Pythoncard-users] SplitterBackground and testSplitter sample

[Kevin A. <al...@se...>]

Yesterday I checked in a new model.py that contains a very experimental 
SplitterBackground subclass of Background along with a testSplitter 
sample as a proof-of-concept of a 3 pane IDE-like window that contains 
three separate panes (left, right-top, right-bottom). All the work is 
done in the on_initialize method and was more or less stolen from the 
wxPython demo Main.py file but it does show that backgrounds of other 
samples can be used as panes in splitters similar to how pages in a 
Notebook currently work by changing the superclass from Background to 
PageBackground.

If you have been waiting for splitter support, I would appreciate some 
feedback on the types of windows or apps you were looking forward to 
creating to get a better idea of whether we should just support a 
default set of the most common pane configurations or allow unlimited 
nesting. If there are particular samples or tools that you think would 
benefit from the use of splitters as opposed to a single pane static or 
sizer layout, etc. please say so, as those might make good tests of 
features and expose problems with my simple wrapper.

There are other issues with regards to where event handlers should be 
located for common functionality, how user code should go about 
determining which pane has focus, etc. I need to get some input from 
the list so that I know whether I should be spending much time on 
splitters before doing release 0.8.1 later this month.
