Simple Button component

A simple cuboid shaped button without caption. Implements responsive button behavoir.

Could be used to subclass differently shaped buttons from. The colours of the front/back and the side faces can be specified.

Example Usage

Two simple buttons which send messages to the console:

Graphline(
    button1 = SimpleButton(size=(1,1,0.3), position=(-2,0,-10), msg="PINKY"),
    button2 = SimpleButton(size=(2,2,1), position=(5,0,-15), msg="BRAIN"),
    echo = ConsoleEchoer(),
    linkages = {
        ("button1", "outbox") : ("echo", "inbox"),
        ("button2", "outbox") : ("echo", "inbox")
    }
).run()

How does it work?

This component is a subclass of OpenGLComponent (for OpenGLComponent functionality see its documentation). It overrides __init__(), setup(), draw() and handleEvents().

It draws a simple cuboid. It is activated on mouse button release over the object and on key down if a key is assigned. On mouse button down it is shrunk by a small amount until the button is released.
