Circle JSlider - Java program

Question

Can someone show me code that will set up a JSlider except, instead of a thumb, it is a circle? Specifically, instead of that little triangle which points to the current position, it is a blue circle of width 100;

Answer 1

Assuming you're using the Metal L&F you could extend javax.swing.plaf.metal.MetalSliderUI and override the horizThumbIcon or vertThumbIcon to be your circle. Then set this UI to be UI you'd like for your sider using slider.setUI()
