import javax.swing.border.*;
public class JSPDemo extends JFrame {
private JPanel contentPane;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
//必须先指定样式, 否则很有可能无效
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
UIDefaults uidefs = UIManager.getLookAndFeelDefaults();
// 设置分割条的颜色了
uidefs.put("SplitPane.background",Color.CYAN);
JSPDemo frame = new JSPDemo();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
