Hello, I and my team are doing a synthesizer for college work, in case I'm doing the graphical interface and would like to make the following buttons:
Themixingbuttonswouldworklikethiskeyboardonline: Synthesizer .
I think I should use a Circular JSlider underneath the button, or even the button, because of how I spin the buttons on the online synthesizer that I linkei (I think it would be easier for the user), but still I have no idea how. Does anyone know of any good material (serves up PDFs), preferably in Portuguese, so I try to learn about Graphics 2D and JSlider?
