With Toolkit.getDefaultToolkit().getScreenSize() I get the actual ScreenSize. But I want the ScreenSize WITHOUT the standard MS-TASKBAR (in consideration of taskbar heigth and position on the screen[can be at N/S/W/E of screen]). Has someone a solution for this without using JNI or has someone a c++ class for that and an instruction how to use it because I havent worked with JNI yet. Any hint would be useful too. Thanks a lot!
