also works for me. and it helps for filtering the right key events (see my
solution).

Seems like a magic for me... Anyway I adopt Christof mixed with João
solutions at this patch.

But arises some questions...

Once I need:
  1. change color of key while mouse click is on at these key
  2. once mouse click is on, and mouse cursor move around the gop area, the
keyboard will respond. Like a finger pressing and moving around a real
keyboard.
  3. the key are velocity sensitive around y axis at first click.

I'm thinking to map the gop are, create a system of coordinates to draw
keyboard and using [cyclone/mousestate] and/or only [iemguts/receivecanvas].

In this way maybe is better implement the João suggestion of parameterize
the template and implement the keys with more points and implement the
control with a gop coordinate system.
