Tkinter matches Tk quite closely, and there's no way to get *all* bindings for a standard widget with a single call at the Tk level (afaik). to extract the same information from a Tkinter widget, you should first call bindtags() on the widget to get a list of binding classes used for this widget, and you can then use bind_class(cls) to get the events for that class. to get all events, you can use something like: >>> bindings = set() >>> for cls in b.bindtags(): ... bindings |= set(b.bind_class(cls)) ... >>> bindings set(['<Alt-KeyRelease>', '<Leave>', '<Enter>', '<KeyRelease-Alt_L>', '<Key-Alt_R>', '<<PrevWindow>>', '<Key-F10>', '<KeyRelease-F10>', '<Key-space>', '<Alt-Key>', '<Button-1>', '<ButtonRelease-1>', '<KeyRelease-Alt_R>', '<Key-Tab>', '<Key-Alt_L>']) </F> -- http://mail.python.org/mailman/listinfo/python-list
