wxIntCtrl question re validator use

wxPython Users
1

Just discovered wxIntCtrl and would like to use it, but I need a custom validator to get/set data from a database.

With the standard wxTextCtrl I figured out how this works (with help from Javier), can someone point me in the right direction on how to go about it with wxIntCtrl.

I believe I will need to do at least the following:

- Create a "class intVal(wxIntValidator)", in which I override (is this the correct term) functions "Clone", "TransferToWindow", "TransferFromWindow" and "__init__".

Any hints or even better a little sample code will be much appreciated.

See you
Werner

Only wxPyValidator is instrumented to be derived from in Python, but you should be able to make your own wxIntCtrl-specific validator from it just as easily as the others.

Robin,

Please bear with me. With the textctrl I could just state the keywork validator, when I tried this with intctrl I get an unexpected keyword argument error. So, I looked at lib.intctrl and saw that there is a wxIntValidator, that is why I thought/guessed that I should derive my validator from it.

Frankly this is why above my head, I am not at all sure how to go about this without loosing the functionality of wxIntValidator.

Any help/hints, or even better some code snipped would be much appreciated.

Best regards
Werner

Sorry, I didn't make the mental connection between your message and the wxIntCtrl in the library. I see Will has already fixed things...

Robin,

No problem, thats why I asked again.

BTW, the more I work with Python and wxPython the more I like it, and this is in large parts due to support provided by people like yourself. - THANKS!

See you
Werner
