How to add a WindowListener to an external event
This is my code I have developed. This is the main program which holds and executes each external JFrame for my Game. chooseGender is an external program which is nothing but a JFrame and its components.
My goal for this is when chooseGender executes, it has 2 buttons for options (male, female) when the user picks one, an actionListener would set th开发者_StackOverflow中文版e frame to setVisible(false) and then have a WindowClosing event open the next JFrame, (chooseRace). This would happen for several more frames but these 2 are for learning purposes. I appreciate the help in advance. :)
So my question is, how would I go about adding a WindowListener to chooseGender in this program so I can close it and open the next one?
package javagame;
import java.awt.EventQueue;
import java.awt.HeadlessException;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;
import javax.swing.JFrame;
public class Main implements WindowListener {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
new chooseGender().setVisible(true);
}
});
EventQueue.invokeLater(new Runnable() {
public void run() {
new chooseRace().setVisible(false);
}
});
}
An easy way to implement this may be just using modal JDialogs
.
The code would be similar to the following:
main {
new chooseGender().setVisible(true);
new chooseRace().setVisible(true);
new chooseAge...
}
You would want to implement a WidowListener
similar to the following:
public class OpenNewWindowWindowListener extends WindowAdapter {
public void windowClosing(WindowEvent e){
// in here open the next window.
}
}
And add that window listener to the correct frame:
// In the constructor for the JFrame
addWindowListener(new OpenNewWindowListener());
And, each of those classes would extend
JDialog
and, in their constructors use setModal(true)
.
