  • e559. 创建窗口

    A frame is a component container that displays its contents in a top-level window with a title bar and buttons to resize, iconify, maximize, and close the frame.

    Unlike most Swing containers, adding a component to a frame is not done with the JFrame.add() method. This is because the frame holds several panes and it is necessary to specify a particular pane to which to add the component. The pane that holds child components is called the content pane. This example adds a text area to the content pane of a frame.

        // Create the frame
        String title = "Frame Title";
        JFrame frame = new JFrame(title);
        
        // Create a component to add to the frame
        JComponent comp = new JTextArea();
        
        // Add the component to the frame's content pane;
        // by default, the content pane has a border layout
        frame.getContentPane().add(comp, BorderLayout.CENTER);
        
        // Show the frame
        int width = 300;
        int height = 300;
        frame.setSize(width, height);
        frame.setVisible(true);
