Method dump

Lib/tkinter/__init__.py:3918–3955

Return the contents of the widget between index1 and index2. The type of contents returned in filtered based on the keyword parameters; if 'all', 'image', 'mark', 'tag', 'text', or 'window' are given and true, then the corresponding items are returned. The result is

(self, index1, index2=None, command=None, **kw)

        return self._getints(self.tk.call(self._w, 'dlineinfo', index))
