How can I get a wxFrame to refresh without having to manually resize it in wxPython?

Question

I have a simple frame in a wxPython script that isn't refreshing like I'd like it to.

Basically the frame starts out blank. The user can then select different datasets to view in a grid form. When the dataset has been chosen, the script creates a grid and puts it in a sizer in the frame. The problem is that the frame shows the grid in a very small size, the sizer isn't expanding like it should (or at least how I'd expect it to). Furthermore when I resize the frame manually (ie with the mouse) the sizer suddenly expands like it should, and the whole frame is filled with the grid.

How can I get the sizer to expand the grid right away, and not only when I resize the frame manually?

Answer 1

Call Layout() on the sizer containing the grid.
