如何为 JSlider 配置拇指大小？
使用默认值，以及 JSlider 的范围为256，拇指只有几个像素宽，这使得用鼠标控制变得非常困难。
With the defaults, and a range for the JSlider of 256, the thumb is only a few pixels wide, which makes it quite difficult to control with a mouse.
我使用Windows 7的外观和滑块看起来像这样：

启用 paintTicks 的主要和次要tick spacing of 0给出了一个更好的（虽然不是首选）显示：

推荐答案
您可以尝试自定义 JSl ider 外观如下：
You could try customizing the 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

请注意，这些更改将适用于所有 JSlider 实例，这可能是使这种做法不受欢迎。
It's important to note that these changes will apply to all JSlider instances, which may make this approach undesirable.
