我在互联网上找到了关于如何使用xml来自定义Java中的Slider的示例,一切正常:

import javax.swing.JFrame;
import javax.swing.JSlider;
import javax.swing.UIManager;
import javax.swing.WindowConstants;
import javax.swing.plaf.synth.SynthLookAndFeel;

public class Main {

    public static void main(String[] args) {

        try {
            SynthLookAndFeel laf = new SynthLookAndFeel();
            File initialFile = new File(
                    "/pathTo/jslider.xml");
            InputStream targetStream = new FileInputStream(initialFile);
            // laf.load(Test.class.getResourceAsStream("demo.xml"), Test.class);
            laf.load(targetStream, Main.class);
            UIManager.setLookAndFeel(laf);
        } catch (Exception e) {
            e.printStackTrace();
        }

        JFrame f = new JFrame();
        f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        JSlider jslider = new JSlider() {
            {

                setVisible(true);
            }
        };
        jslider.putClientProperty("JSlider.isFilled", Boolean.TRUE);

        f.add(jslider);
        f.setSize(320, 240);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }
}

使用xml文件:

<synth>
    <style id="backingStyle">
        <opaque value="TRUE"/>
        <font name="Dialog" size="12"/>
        <state>
            <color value="WHITE" type="BACKGROUND"/>
            <color value="BLACK" type="FOREGROUND"/>
        </state>
    </style>
    <bind style="backingStyle" type="region" key=".*"/>

    <style id="SliderTrackStyle">
        <opaque value="TRUE"/>
        <state>
            <color type="BACKGROUND" value="ORANGE"/>
        </state>
    </style>
    <bind style="SliderTrackStyle" type="region" key="SliderTrack" />

    <style id="SliderThumbStyle">
        <opaque value="TRUE"/>
        <state>
            <color type="BACKGROUND" value="GRAY"/>
        </state>
        <state value="PRESSED">
            <color type="BACKGROUND" value="BLACK"/>
        </state>


    </style>
    <bind style="SliderThumbStyle" type="region" key="SliderThumb" />
</synth>

基本上我有两个问题:

1)现在您可以看到我使用过:

jslider.putClientProperty("JSlider.isFilled", Boolean.TRUE);

因为我希望看到左侧部分已填满。但这不起作用。

2)除此之外,我想定义用于填充该部分的颜色,但我无法在互联网上找到xml标签来定义该颜色。

有什么建议吗? 先感谢您。
