Java 在Nimbus主题中更改ProgressBar Swing的UI查找

我想将NetBeans中Nimbus UI的Progressbar颜色从默认的橙色更改为绿色

我增加了以下几行

for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    UIDefaults defaults= UIManager.getDefaults();

                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Finished].foregroundPainter", Color.GREEN);
                    UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Finished].backgroundPainter", Color.GREEN);
                    break;
                }
            }

这不会做出任何改变。对代码或任何其他解决方法的任何更正？

Nimbus的操作与其他外观和感觉不同（对我们来说是的）

通常您应该使用

ColorUIResource

，但Nimbus更喜欢使用

Painter

我从那里偷了画师，所以这里有一个快速的解决方案：如果你不自己写画师，就更改所有组件的

nimbusOrange

颜色

UIDefaults defaults = UIManager.getLookAndFeelDefaults();
NimbusLookAndFeel localNimbusLookAndFeel = (NimbusLookAndFeel)UIManager.getLookAndFeel();
Color derivedColor = localNimbusLookAndFeel.getDerivedColor("nimbusBase", 0.03054375F, -0.3835404F, -0.0980392F, 0, true);
defaults.put("nimbusOrange",derivedColor);

对我来说，一个快速的解决方案是：如果您没有自己编写画师，请更改所有组件的

nimbusOrange

颜色

UIDefaults defaults = UIManager.getLookAndFeelDefaults();
NimbusLookAndFeel localNimbusLookAndFeel = (NimbusLookAndFeel)UIManager.getLookAndFeel();
Color derivedColor = localNimbusLookAndFeel.getDerivedColor("nimbusBase", 0.03054375F, -0.3835404F, -0.0980392F, 0, true);
defaults.put("nimbusOrange",derivedColor);

这可以帮助您：

private void paintJProgressBar(Color color, JProgressBar progressBar) {
    UIDefaults defaults = new UIDefaults();
    Painter painter = new MyPainter(color);
    defaults.put("ProgressBar[Enabled].foregroundPainter", painter);
    defaults.put("ProgressBar[Enabled+Finished].foregroundPainter", painter);
    progressBar.putClientProperty("Nimbus.Overrides.InheritDefaults", Boolean.TRUE);
    progressBar.putClientProperty("Nimbus.Overrides", defaults);
}

class MyPainter extends AbstractRegionPainter {

    private Color fillColor;

    public MyPainter(Color color) {
        fillColor = new Color(
                color.getRed(), color.getGreen(), color.getBlue(), 220);
    }

    @Override
    public void doPaint(Graphics2D g, JComponent c, int width,
                        int height, Object[] extendedCacheKeys) {
        g.setColor(fillColor);
        g.fillRect(3, 3, width - 6, height - 6);
    }

    @Override
    public PaintContext getPaintContext() {
        return null;
    }

}

这可以帮助您：

private void paintJProgressBar(Color color, JProgressBar progressBar) {
    UIDefaults defaults = new UIDefaults();
    Painter painter = new MyPainter(color);
    defaults.put("ProgressBar[Enabled].foregroundPainter", painter);
    defaults.put("ProgressBar[Enabled+Finished].foregroundPainter", painter);
    progressBar.putClientProperty("Nimbus.Overrides.InheritDefaults", Boolean.TRUE);
    progressBar.putClientProperty("Nimbus.Overrides", defaults);
}

class MyPainter extends AbstractRegionPainter {

    private Color fillColor;

    public MyPainter(Color color) {
        fillColor = new Color(
                color.getRed(), color.getGreen(), color.getBlue(), 220);
    }

    @Override
    public void doPaint(Graphics2D g, JComponent c, int width,
                        int height, Object[] extendedCacheKeys) {
        g.setColor(fillColor);
        g.fillRect(3, 3, width - 6, height - 6);
    }

    @Override
    public PaintContext getPaintContext() {
        return null;
    }

}
