Java – sets the size of the jslider

How do I configure the thumb size for jslider?

Solution

You can try to customize jslider look and feel as follows:

UIDefaults defaults = UIManager.getDefaults();
defaults.put("Slider.thumbHeight",HEIGHT_AS_INTEGER); // change height
defaults.put("Slider.thumbWidth",WIDTH_AS_INTEGER); // change width

Please note that these changes will apply to all jslider instances, which may make this method undesirable
