> I have a question and getting a bug >> This code I don't really understand the BindingTestCaptureFrame.button = self. I dont see any "button" frame or variable defined in the xml >> function BindingTestButton_OnClick(self, button) > if button == "LeftButton" then > BindingTestCaptureFrame.button = self > BindingTestCaptureFrame:Show() > elseif button == "RightButton" then > local key = GetBindingKey(self.command) > if key then > SetBinding(key, nil) > end > BindingTestButton_OnEnter(self) > end > end The section of the book that discusses widget scripts states that each script is automatically called with certain arguments. You can consult the documentation for [OnClick][1] to see what these are. If you're using XML you'll need to either explicitly pass these arguments to your handler function, or if you use the `function="BlahBlah"` syntax, it will do it for you.
