How to get a validator to work in a frame

I guess the problem was that I was calling Validator on self and on
the input control, but never on panel. I don't understand why it
should be called on panel though, instead of the control itself. I
think the recursive flag only needs to be set if you call the method
on a parent control (such as self or panel, I guess), but I would
think it would work without the flag if called from the input control.

Hi John,

I got it to work, but frankly I don't understand why it did not work in
the first place.

Kept a reference to the panel, and then called validate on the panel.
Ah, maybe that is the problem, maybe you need to use the
"wxWS_EX_VALIDATE_RECURSIVELY" on your frame.

Because window.Validate is designed to be called on container windows to validate all the children of the window, and if the window has the wx.WS_EX_VALIDATE_RECURSIVELY extended style set then it also calls Validate of the child windows so that their children can be validated as well.
