如何将框架分为两部分

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);    }}
