    Default My own version of swing?

    Hi guys! I REALLY want to write myself a complete GUI library, but the thing is.. I dont know how to draw directly to the screen... I can easily draw to a graphics object in a canvas or something like that, but I dont know how to draw a my own frame on the screen without using another frame... I hope im making sense, not really sure how to say it... So, my question is: How do I draw to the screen without using any frame/canvas/panel/etc. so I can draw my own frames and other components? There must be a way since Swing can do it... right?

    If I understand you correctly, you will need to rely on native code (eg JNI) - how you do so with native code is OS dependent.

    So, if I want to do this, i will HAVE to code native stuff aswell as java... I cant just use the stuff swing uses somehow? Too much work?

    Swing uses AWT as it's drawing backend, which is basically what copeg described: it uses native code to draw basic components and stuff. It has been implemented on a large number of platforms because it had quite a large corporate backing (Sun Microsystems, now Oracle and the Java open-source community).

    There is another native backend which I believe IBM wrote called SWT. I've never used it, but it's what Eclipse uses for drawing GUI's.

    Anything lower-level will require you to write the native backend yourself using JNI (keep in mind that the native backend has to be written/compiled on every platform you want to support).
