wxFormBuilder and wxPropertyGrid questions

I'm doing a test with the FormBuilder and wxPropertyGrid (from wxAdditions). Does anyone know how to change the default properties in the grid in the editor?

Also, am I going to have any problems converting this to wxMax using the codegen tool?

I really like wxFormBuilder but I'm having real problems getting the smaller gadgets (wxStaticText/wxTextCtrl) to lay out as I would like using the Box/Grid sizer controls. Any pointers here would be great.

Trying to do a side panel, something like this:

CodeGen doesn't know how to generate code for property grids yet. When I did it I used a button in its place when I designed the frame. Then I just replaced it with my property grid after the code was generated.
