best way to disable editing widgets ?

I'm using validators to achieve the same result as wx.TextCtrl.SetEditable() but on different kinds of widgets (wx.CheckBox).
I use the following validator:

class ProtectValidator(wx.PyValidator):
    def __init__(self):
        wx.PyValidator.__init__(self)
        self.Bind(wx.EVT_CHAR, self.OnChar)
        self.Bind(wx.EVT_MOUSE_EVENTS, self.OnMouse)
    def Clone(self):
        return ProtectValidator()
    def Validate(self, win):
        return False
    def OnChar(self, event):
        return
    def OnMouse(self, event):
        return

testCheck = wx.CheckBox(pane, -1)
testCheck.SetValidator(ProtectValidator) #to disable "editing"
testCheck.SetValidator(wx.Validator()) #to enable "editing"

I don't know if the default validator of a chekbox is really a wx.Validator(), is it automatically mapped to the underlying wxGenericValidator? Anyway it works.

Is there a simpler/better solution?
Something like Enable(False) on the parent window but without shading out everything?

You can use the existing wx.DefaultValidator instance.

Also, if you ever use this on a control in a dialog then the dialog will not be able to be OK'ed as long as Validate returns False. You may want to change that to True. (Afterall, the value is Valid regardless of whether the widget is protected or not, right?) Use on a dialog will also require that the validator implement the TransferToWindow and TransferFromWindow methods. They can also just return True for this case.

No, Enable/Disable is the only thing available for all control types.
