Various pluggable Look and Feels such as the JGoodies Plastic L&F render a WindowBar background color that does not blend well with the corresponding panels around it. If there are no minimized tabs within this same WindowBar, it also shows a WindowBar background width/height of about 4-5 pixels with this background color (see attached screenshot). How do you change the background color of the WindowBar or the minimum width/height of it? I've tried all the obvious properties but none of them work including:
rootWindow.getRootWindowProperties().getWindowBarProperties().setMinimumWidth(0);
rootWindow.getRootWindowProperties().getWindowBarProperties().getComponentProperties().setBackgroundColor(Color.red);
