I'm creating a slider bar, which will be a subclass of JSlider, as part of a logging gui. What I'd like to do is be able to draw some items above the slider bar (e.g. a "volume" display, indicating how much logging info will be spit out by a particular setting). I have overridden the paintComponent() method, but I'm getting a bit confu...

Can anyone tell me how to add text to the pane without letting the user manipulate what is there? publi...
