PyGTK: how to make a clipboard monitor?

How can I make a simple clipboard monitor in Python using the PyGTK GUI?

I found gtk.clipboa开发者_StackOverflow社区rd class and but I couldn't find any solution to get the "signals" to trigger the event when the clipboard content has changed.

Any ideas?

Without a proper notification API, such as WM_DrawClipboard messages, you would probably have to resort to a polling loop. And then you will cause major conflicts with other apps that are trying to use this shared resource.
Do not resort to a polling loop.
