Got double left mouse click Widget=.25763696 X=300 Y=68For mouse-related events, callbacks print the X and Y coordinates of the mouse pointer,
in the event object passed in. Coordinates are usually measured in pixels from the
upper-left corner (0,0), but are relative to the widget being clicked. Here’s what is
printed for a left, middle, and double-left click. Notice that the middle-click callback
dumps the entire argument—all of the Event object’s attributes (less internal names
that begin with “” which includes the doc__ string, and default operator overload-
ing methods inherited from the implied object superclass in Python 3.X). Different
event types set different event attributes; most key presses put something in char, for
instance:
C:\...\PP4E\Gui\Tour> python bind.py
