Please Hlp with msg: "The C++ part of the StaticText object has been deleted"

[Mike C. Fletcher]

wxPyDeadObjectError is a catch that prevents you from getting a core 
dump/memory-access-violation when you try to call a method or access an 
attribute of an object which has already been cleaned up/destroyed by 
the system.  wxPyDeadObject's evaluate to false, so you can do this:
    if self.testLab:
        self.testLab.SetLabel('test')
or you can just catch the error:

    try:
       self.testLab.SetLabel( 'test' )
    except wx.PyDeadObjectError, err:
       pass # just ignore it...

In this case, it looks like the event is occurring after the testLab 
widget has been destroyed.  Since you likely don't want to change the 
appearance of it at that point, nothing is lost.

HTH,
Mike
