我在样式化JScrollPane时遇到了麻烦。我只想能够改变滑块和背景的颜色(同时也删除增加/减少按钮)。到目前为止,我尝试了以下方法:
this.setBackground(new Color(0,0,0));
this.viewport.setBackground(new Color(0,0,0));
this.getViewport().setBackground(Color.BLACK);
this.setOpaque(false);
this.getVerticalScrollBar().setUI(new BasicScrollBarUI()
{
@Override
protected JButton createDecreaseButton(int orientation) {
return createZeroButton();
}
@Override
protected JButton createIncreaseButton(int orientation) {
return createZeroButton();
}
@Override
protected void configureScrollBarColors(){
}
});
this.getHorizontalScrollBar().setUI(new BasicScrollBarUI()
{
@Override
protected JButton createDecreaseButton(int orientation) {
return createZeroButton();
}
@Override
protected JButton createIncreaseButton(int orientation) {
return createZeroButton();
}
});
}
private JButton createZeroButton() {
JButton jbutton = new JButton();
jbutton.setPreferredSize(new Dimension(0, 0));
jbutton.setMinimumSize(new Dimension(0, 0));
jbutton.setMaximumSize(new Dimension(0, 0));
return jbutton;
}
此外
UIManager.put("ScrollBar.trackHighlightForeground", (new Color(57,57,57)));
UIManager.put("scrollbar", (new Color(57,57,57)));
UIManager.put("ScrollBar.thumb", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.thumbHeight", 2);
UIManager.put("ScrollBar.background", (new Color(57,57,57)));
UIManager.put("ScrollBar.thumbDarkShadow", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.thumbShadow", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.thumbHighlight", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.trackForeground", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.trackHighlight", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.foreground", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.shadow", new ColorUIResource(new Color(57,57,57)));
UIManager.put("ScrollBar.highlight", new ColorUIResource(new Color(57,57,57)));
使用以上所有代码,我得到了一个带有白色背景的变暗拇指。有趣的是,如果我删除setUI函数,我会得到一个带有变暗背景的默认拇指。
有什么想法吗?
谢谢
已解决******
上面的configureScrollBarColors函数可以按以下方式使用:
@Override
protected void configureScrollBarColors(){
this.thumbColor = Color.GREEN;
}
这将把拇指的颜色变成绿色。
