如何在 Java 中向 JDesktopPane 中新增內部框架?
首先,建立一個 JDesktoPane −
JDesktopPane desktopPane = new JDesktopPane();
現在,建立一個內部框架並將其新增到 JDesktopPane −
JInternalFrame intFrame = new JInternalFrame("Our Frame", true, true, true, true);
desktopPane.add(intFrame);
The following is an example to add Internal Frame to a JDesktopPane −
package my;
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JLabel;
public class SwingDemo {
public static void main(final String[] args) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JDesktopPane desktopPane = new JDesktopPane();
JInternalFrame intFrame = new JInternalFrame("Our Frame", true, true, true, true);
desktopPane.add(intFrame);
intFrame.setBounds(50, 90, 200, 250);
JLabel label = new JLabel(intFrame.getTitle(), JLabel.CENTER);
JButton button = new JButton("Demo Button");
intFrame.add(label, BorderLayout.CENTER);
intFrame.add(button, BorderLayout.WEST);
intFrame.setVisible(true);
frame.add(desktopPane, BorderLayout.CENTER);
frame.setSize(600, 500);
frame.setVisible(true);
}
}輸出

在上述內部框架中單擊最大化按鈕後,結果如下:−
