I've been playing around a little with the wx.lib.masked.numctrl
package. There's a control named NumCtrl that basically does what you're
looking for. I reckon you might want to tinker around with it a little
and see if it works for you. You might have to write your code in a way
that it creates and binds the control to your pythoncard frame at init
(override the __init__ method of the PythonCard.model.Background or
PythonCard.model.PageBackground to load up the control)
eg.
from PythonCard import model,
from wx.lib.masked import numctrl
class myframe(model.Background):
def __init__(self, aParent, aBgRsrc):
model.Background.__init__(self, aParent, aBgRsrc)
self._initControls()
def _initControls(self):
self.txtText = numctrl.NumCtrl(self.panel, value=1234)
self.txtText.SetParameters(groupDigits=False, allowNegative=False,
useFixedWidthFont=False, max=5, limited=True)
