我已经通过这个网站去改变外观和感觉的JSlider
,但除了Slider.altTrackColor
没有别的工作。 我想要做的事一样显示在PIC1任何建议将是很大的帮助。 我工作的JDK 1.6。
UIDefaults defaults = UIManager.getDefaults();
defaults.put("Slider.altTrackColor", Color.red);
defaults.put("Slider.thumb", Color.red);
我也试过这样:
WindowUtilities.setNativeLookAndFeel();
// WindowUtilities.setNimbuzzLookAndFeel();
// WindowUtilities.setJavaLookAndFeel();
WindowUtilities是一流的,告诉系统使用本机的外观和感觉,因为在以前的版本。 金属(Java)的LAF否则默认。
public static void setNativeLookAndFeel() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch(Exception e) {
System.out.println("Error setting native LAF: " + e);
}
这里是第一个图像上显示的工作UI的一个完整的例子:

您可以轻松地通过改变返回的边界修改拇指(夹具)的大小。 拇指画会适应任何尺寸。 而且你还可以轻松地定制任何其他滑块部分的画。
这里顺便最终观点:
PS我没有适应UI的垂直滑块,但不应该花太长时间。
