如何更改 JColorChooser 的色板组件的颜色?

How Do You Change The Color on The Swatches Component of JColorChooser?

我正在尝试制作一个涉及 JColorChooser Swatches 组件的绘图应用程序,并且我正在尝试使我的 UI 成为某种颜色。除了 "Recent" 框周围的一小块区域外,我几乎可以通过在几乎所有地方设置背景来更改颜色。 Screenshot

如有任何帮助,我将不胜感激,我将在下面粘贴部分代码以供参考:

 //Sets up color chooser
  chooser = new JColorChooser(Color.BLACK);
  AbstractColorChooserPanel[] panels = chooser.getChooserPanels();
  for (int i = 0; i < panels.length; i++) {
     if (!panels[i].getDisplayName().equalsIgnoreCase("Swatches"))
         chooser.removeChooserPanel(panels[i]);
     else {
        panels[i].setBackground(new Color(0, 155, 228));
     }
  }
  chooser.setPreviewPanel(new JPanel());
  //Sets up size slider
  sizeSlide = new JSlider(1, 45);

  //Adds Color/Size to one control panel, adds new panel to bottom of 
  //main
  optionP = new JPanel();
  optionP.setBackground(new Color(0, 155, 228));
  optionP.setLayout(new BorderLayout());
  optionP.add(sizeSlide, BorderLayout.EAST);
  optionP.add(chooser, BorderLayout.WEST);
  this.add(optionP, BorderLayout.SOUTH);    

我认为如果不通过 JComponent 树进行一些复杂的搜索,就无法做到这一点。但是即使我无法更改背景颜色。

编辑: 我终于设法用下面的代码改变了最近面板的背景颜色:

JColorChooser chooser = new JColorChooser(Color.BLACK);
AbstractColorChooserPanel[] panels = chooser.getChooserPanels();
for (int i = 0; i < panels.length; i++) {
    if (!panels[i].getDisplayName().equalsIgnoreCase("Swatches")) {
        chooser.removeChooserPanel(panels[i]);
    } else {
        panels[i].setBackground(new Color(0, 155, 228));
        // placing code to change recent panel background color here
        // will not work for some odd reason
        // JComponent component = (JComponent) panels[i].getComponent(0);
        // component.setBackground(new Color(0, 155, 228));
    }
}
AbstractColorChooserPanel panel = chooser.getChooserPanels()[0];
JComponent component = (JComponent) panel.getComponent(0);
component.setBackground(new Color(0, 155, 228));

另一种方法可行,但它会更改整个应用程序中所有面板的背景。使用 UIManager 更改背景:

UIManager.put("Panel.background", new ColorUIResource(0, 155, 228));
