How do I layout a 3 pane window using wxPython?

I am trying to find a simple way to layout a 3 pane window using wxPython.

I want to have a tree list in the left pane, then have a right pane that is split into two - with an edit component in the top part and a grid component in the bottom part.

Something along the lines of:


--------------------------------------
| | |
| | Edit |
| Tree | Control |
| Control | |
| |----------------------|
| | |
| | Grid |
| | |
--------------------------------------


I would like the window to be re-sizable and give the user the ability to change the (relative) size of each of the components within the windows by dragging the borders.

I figure that I need some combination of sizers and/or splitter-window components but can't find a decent example of this kind of window in the documentation or on the web.

Answer

First of all download wxGlade a gui builder for wxPython (alternative XRCed, i prefere wxGlade).

Then you have to decide if you want to use a GridSizer or a Splitter and you are done. Below you find both (between Tree and right side is a GridSizer -> resizes automatically). Between Edit and GridCtrl is a Sizer (manual Resize).
