The standard implementation of drawButtonBackground() in LookAndFeel_V3 is with a colour gradient, giving the buttons a plastic, 3-dimensional look. I noticed that in LookAndFeel_V4 this colour gradient apparently has been removed from drawButtonBackground(), so when I just change the LookAndFeel version form V3 to V4, all buttons suddenly look “flat”.
Is there a standard way in LookAndFeel_V4 to draw buttons with a 3-d appearance, or would I have to derive something myself?
