I cleaned it up a little and did this, but of course this doesn't work.
Is this the wrong way to create a function (not method) within a class?
def Validate(self, parent):
text_ctrl = self.GetWindow()
text = text_ctrl.GetValue()
try:
if not text or int(text) <= 0:
error_message()
return False
else:
return True
except ValueError:
error_message()
return False
@staticmethod
def error_message():
wx.MessageBox('Enter a valid time.', 'Invalid time entered',
wx.OK | wx.ICON_ERROR)
