正如Amir所说，您想为此使用JSplitPane。我已经在您的代码中添加了它。看看这个。
public static void main(String[] args) { GlassView view = new GlassView();}private static class GlassView extends Jframe { private int width = 600; private int height = 750; public GlassView() { this.setSize(width, height); this.setVisible(true); this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); JPanel glass = new JPanel(); glass.setSize(450, 750); glass.setBackground(Color.BLUE); glass.setVisible(true); JPanel controls = new JPanel(); controls.setSize(150, 750); controls.setBackground(Color.RED); controls.setVisible(true); JSplitPane splitPane = new JSplitPane(); splitPane.setSize(width, height); splitPane.setDividerSize(0); splitPane.setDividerLocation(150); splitPane.setOrientation(JSplitPane.HORIZONTAL_SPLIT); splitPane.setLeftComponent(controls); splitPane.setRightComponent(glass); this.add(splitPane); }}
