[Tkinter-discuss] buttonpress

[Stewart Midwinter]

Pavel, what operating system are you on, and what version of Python,
and what version of Tcl/Tk?

Also note that to see the code work, you need to click on the button
itself, which might be a bit hard as it is quite narrow.  To make the
button wider, give it some text.  Also note that the events will be
printed in a console window, not in the application itself.

Below a version of Jeff's test app that shows the events in the
application itself, in a label.
