i want to use validators for my xml generated dialogs.
within the manual i found this:
../docs/wx/wx476.htm#validatoroverview
--- snip ---
So if using validators and a normal OK button, you may not even need to
write any code for handling dialog dismissal.
If you load your dialog from a resource file, you will need to iterate
through the controls setting validators, since validators can't be
specified in a dialog resource.
--- snip ---
could someone please give me a hint how to do this?

Well the text is about using the old style resources but I think the same
thing applies to xrc. What you'll want to do is get the window that needs
the validator using FindWindowById and then calling SetValidator on it.

Right. I'll only add that you can use XRCCTRL("name") to access the
window, you need not use FindWindow(ById) directly.

Oops, yes I forgot about that. Much easier...

thanks for your hints, but how does the validator know how many
TextCtrl's are within the dialog and how they should be validated?

Because you should assign a new validator instance to each control that
needs one, and presumably the type of validator you use and/or how you
initialize it will determine how it validates.

ok, but how can i iterate through the controls of the xml generated
dialog and how can i determine the type of the control (if i don't know
how the dialog is setted up)?

Parse the XML yourself and for all the "object" nodes get the "name"
attribute and use that with XRCCTRL to get the actual widget.
