That's my code.
I wanna dispose all except Login Form when I click LogOut Menu :(, but It's only close the current JFrame, the others active JFrames don't close automatically when logged out.

Any solutions?

[mrmatt1111]

edit: oops, missread.

[r035198x]

You need to have references to those frames in order to be able to call dispose on them. Currently you are just creating them without creating the references to manipulate them with.

any simple examples ti create the references? :confused:

[r035198x]

Sure,

new LoginForm();

creates a new LoginForm object but no references to manipulate that object with.

LoginForm aLogInForm = new LoginForm();

creates both a new LoginForm object and a reference to that object called "aLogInForm".
We can now manipulate the log in form object as we wish by calling it's methods (including dispose()) through the aLogInForm reference.

[sysout]

how do I know which JFrame is an active one (which is open at the current time?)

[r035198x]

One way is to derive it from the logic that you put in the code. Most of the time it will be possible to know if you go through the steps that your code will be going through as it is executing.

Another approach is to simply use those references to check. JFrames have a isVisible() method.

[DarrylBurke]

> I wanna dispose all except Login Form when I click LogOut Menu
Maintain a visible reference to your Login Form and use the static method of Frame to get an array of all Frames.

Frame[] frames = Frame.getFrames();
for (Frame frame : frames) {
   if (frame != loginForm) {
      frame.dispose();
   }
}

db

[sysout]

This is my code, still have errors :(

        Functions f = new Functions();
        Frame frames[] = f.getFrame();
        for (Frame frame : frames) {
           if (frame != LoginForm && frame!= null) {
              frame.dispose();
           }
        }
        new LoginForm().setVisible(true);

Functions.java have this code :

    private Frame frames [] = new Frame[30];
    public int frameIndex = 0;
    
    public void setFrame(Frame newFrame){
        frames[frameIndex] = newFrame;
    }

    public Frame[] getFrame(){
        return frames;
    }

Is this work palz?

[RamyaSivakanth]

Send a complete code.It will be useful for giving good solution.

One suggestion is

do like this below and try

1. frame.setVisible(false);

2. frame.dispose();

[r035198x]

What errors are you getting? Post the error messages.

Why are you doing new LoginForm().setVisible(true);? You already have a LogInForm at that stage (the one you were checking against in the for loop). Just toggle that one to visible.
