""" """
Demonstration of setting an Element's Widget to use a different cursor than the Demo Cursors
standard arrow. In this case, the cursor is changed into a hand when hovering over the Text Element.
This implementation relies on accessing the underlying tkinter widget to change the cursor as there is currently no method provided for you to modify a widget's cursor. Accessing an Element's tkinter widget is easy and straightforward, you simply write: Demonstration of setting an Element's Cursor to use a different cursor than the standard arrow.
window[key].Widget Can also change Cursor at the Window level.
If you want no cursor, set the cursor to the string 'none'.
