take a look at maskededit.py in the current CVS tree under lib/
It can do that and more.

There's an excellent integer control in the demo that comes with
wxPython 2.4.0.7. The first section (called Recent Additions) contains
"wxIntCtrl" which should be exactly what you're looking for.
Unfortunately, I don't know if it's included in, or accessible from Boa
- maybe someone else has some experience with adding or using Boa
controls. Good luck,
Dan Cherry

You can also build a small validator that makes sure that alpha characters
are not accepted. Take a look at the demo's wxValidator section under Core
Windows/Controls.

I'd try using what u suggested but it still doesn't
work. I make a new module TextObjectValidator.py & all
the source is the same like in the demo(class
TextObjectValidator). In wxFrame I add:

from TextObjectValidator import TextObjectValidator

& tried:

1. self.Umur = wxTextCtrl(id=wxID_MAINMENUUMUR,
name='Umur', parent=self.panel1, pos=wxPoint(168, 88),
size=wxSize(100, 21), style=0, value='',
validator=TextObjectValidator())

or

2. self.Umur = wxTextCtrl(id=wxID_MAINMENUUMUR,
name='Umur', parent=self.panel1, pos=wxPoint(168, 88),
size=wxSize(100, 21), style=0, value='')
self.Umur.SetValidator(TextObjectValidator())

or

3. in my wxButton event I add:
    self.Umur.SetValidator(TextObjectValidator())

But nothing works. When I tried to go to designer mode
in Boa I got error message "name TextObjectValidator"
not defined when I tried 1 & 2

help me please

Look at the MyValidator class in the same module, it is closer to what you are wanting I think.

This code bellow works. Though, it doesn't capture the copy&paste insertions
to the wxTextCtrl. In other word you can 'copy' some text that contains
alpha characters and 'paste' it to the control.

BTW: Will (Sadkin), how did you handle this (copy & paste) thing in
wxMaksedTextCtrl?

Hi Danu,

wxIntCtrl and/or maskeditctrl should do what you want - latest editions are in the CVS.

To use them from within Boa you should be able to define them as custom classes (examples\advanced\customclasses) in Boa, haven't tried these particular controls but it did the trick for others.

See you
Werner
