Java大规模多帧实例问题

Question

sigh OK guys... There is going to be a painstaking amount of code here, but i'm going to do it anyway.
So basically, I have a custom made (well it's actually just a HEAVILY customized version of a JFrame) and am having major issues.

I have a background. (Fair enough, that's fine) THEN I have a Terminal frame that pops up and spits stuff out. This Terminal frame is based off another class named CustomFrame. I also have ANOTHER class called Notification, which is ALSO a frame class like Terminal ALSO based off Custom Frame.

In the beginning, background loads fine. Terminal loads fine. Calls method to show Notification window. And thats where the problem rises. The notification window won't show.

I have tried frame.setVisible(); frame.setSize(); frame.setLocation(); I have tried, EVERYTHING.

And if I don't show Terminal at all, it seems to spit it's code onto Notification instead, almost like there can only be ONE instance of the CustomFrame open AT ALL TIMES.

I hope you understand my problems... So here is the code!

Game.java

public class Game implements KeyListener {

int BACK_WIDTH = java.awt.Toolkit.getDefaultToolkit().getScreenSize().width;
int BACK_HEIGHT = java.awt.Toolkit.getDefaultToolkit().getScreenSize().height;

JFrame back_frame = new JFrame();
JPanel window = new JPanel();
JLabel title = new JLabel(Variables.TITLE);

Terminal login = new Terminal();

public static void main(String[] args) {
    new Game();
}

public Game() {
    try {

        back_frame.setSize(BACK_WIDTH, BACK_HEIGHT);
        back_frame.setLocation(0, 0);
        back_frame.getContentPane().setBackground(Color.BLACK);
        back_frame.setUndecorated(true);
        back_frame.setVisible(true);
        back_frame.add(window);
        window.setBackground(Color.BLACK);
        window.setLayout(null);

        window.add(title);
        title.setBounds((BACK_WIDTH / 2) - (550 / 2), (BACK_HEIGHT / 2) - (50 / 2), 550, 50);
        title.setForeground(Color.WHITE);

        back_frame.addKeyListener(this);
        login.addKeyListener(this);
        login.setLocationRelativeTo(null);

On a serious note though, if anyone is able to help me with such a sizeable post, I will SERIOUSLY be eternally grateful.

Cheers and thankyou... ALOT.

Edit:

Did have the time to fix up fonts. Extremely sorry, now it has been done.

Edit:

Here is where the Notification frame is called and doesn't end up showing:

if(!(text.length() == 13)) {
    dumpToLog();
    slowPrint("Registry not available at this current given time.\n");
    //TODO: Create registry system.
    new Notification("test");
}

Answer 1

As @Andrew Thompson, @trashgod pointed, it is a bad practice to use multiple frames.

If you still need to fix your problem, here goes:

The issue is with your static instance of the CustomFrame for your Game application and then modifying that frame instance using methods like setUndecorated(...) .

In your Terminal class, you have

static CustomFrame frame = new CustomFrame(Types.TERMINAL);

and in your Notification class, you have

static CustomFrame frame = new CustomFrame(Types.NOTIFICATION);

but you are getting the same instance of the frame

static JFrame frame = new JFrame(); (in your CustomFrame class)

So what this means :

When the Game application loads, the Terminal is visible. And when you register a user, you are displying a Notification , with modified frame size and then by calling the setVisible() method of the CustomFrame .

Which is causing the issue. The setUndecorated() and setVisible() is invoked for the same static instance. YOU CANNOT MODIFY A FRAME WHICH IS VISIBLE . Meaning, YOU CAN ONLY MODIFY A FRAME BEFORE IT IS VISIBLE . Here your frame is already visible (for Terminal) and when displaying the Notification you are trying to change the size and display. WHICH IS WRONG.

As you said I want DIFFERENT JFrames, as in my code, I use Types.java as an enum to pick my different TYPES of frames. The frame is completely different each time due to the use of different components and sizing , to achieve this, you need multiple instances for each type of frame.
