SashLayoutWindow problem

wxPython Users
1

hello ML,
I can't get the grid in the left side of the wx.MDIChildFrame displayed correctly (see code below). It all works fine if I use a wx.Frame instead. Where am I going wrong?

thanks in advance for an answer

Getting the call parameters can be somewhat of a PITA. See below.

Please describe what you mean by displayed correctly. Once I correct the NammeErrors and TypeErrors in your code it appears to work exactly the way the code is written. You should also mention the platform and version that you are using.
