""" pygame.examples.eventlist
Learn about pygame events and input.
At the top of the screen are the state of several device values,
and a scrolling list of events are displayed on the bottom.

Mouse Controls
==============
- 1st button on mouse (left click) to toggle events 'grabed'.
- 3rd button on mouse (right click) to toggle mouse visible.
- The window can be resized.
- Mouse the mouse around to see mouse events.
- If events grabbed and mouse invisible show virtual mouse coords.
Keyboard Joystick Controls
==========================
- press keys up an down to see events.
- you can see joystick events if any are plugged in.
- press "c" to toggle events generated by controllers.
