Flat

public static final int Flat

Displays 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. imings: \n ( AMD K5/133, Diamond Stealth 64 PCI Graphics, widgetsize 29x29 )

flat Approximately 0.7 msec per paint

round Approximately 2.9 msec per paint

sunken Approximately 3.3 msec per paint

The widget will be updated on the next repaining event.
