Display a round or rectangular light emitting diode.
It is configurable to five colors, the two on/off states and three styles (or "looks");
It may display itself in a performant flat view, a round view with light spot or a round view sunken in the screen.
| enum State { Off, On } | State |
Status of the light is on/off.
| enum Shape { Rectangular, Circular } | Shape |
Shades of the lamp.
| enum Look { Flat, Raised, Sunken } | Look |
Display a flat, round or sunken LED.
Displaying the LED flat is less time and color consuming, but not so nice to see.
The sunken LED itself is (certainly) smaller than the round LED because of the 3 shading circles and is most time consuming. Makes sense for LED > 15x15 pixels.
The widget will be updated on the next repaining event.
