Quick Question regarding Frames

[Chris S]

Hello All,
Just starting out with Python and wxPython.  I have two Frames, FrameA
and FrameB.  FrameA opens FrameB when a button on FrameA is clicked.  I
can get this.  Now I want a button on FrameB to update a control on
FrameA.  I am having an issue with this.  Can anyone point me in the
right direction?

Thanks.

Chris
