I'd like to create a GUI in Java which has a top section, a splitter below it and a main content section below the splitter. I'd like to make the splitter real fat (ie 100 pixels high), so that I can place some buttons on it. It could then act like a toolbar and a splitter at the same time in my application.
How would I implement such a thing? Basically the splitter should still behave like a regular splitter when you move it up or down, but it has the added functionality of toolbar buttons on it.
