JPanelを非表示にせずに削除しようとしていますが、機能するものが見つかりません。
これは、ボタンが押されたときにそれ自体を削除する必要があるパネル内のコードです。
play.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Frame frame = new Frame(); //referencing to my JFrame class (this class is a JPanel)
//need to remove this panel on this line
frame.ThreeD(); // adds a new panel
}
});
更新しました
これは完全なコードです:
package ThreeD;
import java.awt.Rectangle;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.UIManager;
import Run.Frame;
public class Launcher extends JPanel{
private JButton play, options, help, mainMenu;
private Rectangle rplay, roptions, rhelp, rmainMenu;
private int buttonWidthLocation, buttonWidth, buttonHeight;
private int width = 1280;
public Launcher() {
this.setLayout(null);
drawButtons();
}
private void drawButtons() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch(Exception e) {
e.printStackTrace();
}
play = new JButton("Play");
options = new JButton("Options");
help = new JButton("Help");
mainMenu = new JButton("Main Menu");
buttonWidthLocation = (width / 2) - (buttonWidth / 2);
buttonWidth = 80;
buttonHeight = 40;
rplay = new Rectangle(buttonWidthLocation, 150, buttonWidth, buttonHeight);
roptions = new Rectangle(buttonWidthLocation, 300, buttonWidth, buttonHeight);
rhelp = new Rectangle(buttonWidthLocation, 450, buttonWidth, buttonHeight);
rmainMenu = new Rectangle(buttonWidthLocation, 600, buttonWidth, buttonHeight);
play.setBounds(rplay);
options.setBounds(roptions);
help.setBounds(rhelp);
mainMenu.setBounds(rmainMenu);
add(play);
add(options);
add(help);
add(mainMenu);
play.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Frame frame = new Frame();
//need to remove this panel here
frame.ThreeD();
}
});
options.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("options");
}
});
help.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("help");
}
});
mainMenu.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("mainMenu");
}
});
}
}
そしてこれは私のFrameクラスです:
package Run;
import javax.swing.*;
import ThreeD.Display;
import ThreeD.Launcher;
import TowerDefence.Window;
import java.awt.*;
import java.awt.image.BufferedImage;
public class Frame extends JFrame{
public static String title = "Game";
/*public static int GetScreenWorkingWidth() {
return java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().width;
}*/
/*public static int GetScreenWorkingHeight() {
return java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().height;
}*/
//public static Dimension size = new Dimension(GetScreenWorkingWidth(), GetScreenWorkingHeight());
public static Dimension size = new Dimension(1280, 774);
public static void main(String args[]) {
Frame frame = new Frame();
System.out.println("Width of the Frame Size is "+size.width+" pixels");
System.out.println("Height of the Frame Size is "+size.height+" pixels");
}
public Frame() {
setTitle(title);
setSize(size);
setResizable(false);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ThreeDLauncher();
}
public void ThreeDLauncher() {
Launcher launcher = new Launcher();
add(launcher);
setVisible(true);
}
public void TowerDefence() {
setLayout(new GridLayout(1, 1, 0, 0));
Window window = new Window(this);
add(window);
setVisible(true);
}
public void ThreeD() {
BufferedImage cursor = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB);
Cursor blank = Toolkit.getDefaultToolkit().createCustomCursor(cursor, new Point(0, 0), "blank");
getContentPane().setCursor(blank);
Display display = new Display();
add(display);
setVisible(true);
display.start();
}
}
