Is there a way to disable all buttons with a method?

This is a lab for school that I'm struggling with, the code is making a game of hangman, and when the "brain" program says the game is over, all of the letter buttons are supposed to be disabled.

relevant code sections:

the buttons:

class ActionButton extends JButton implements ActionListener{
    private String name;
    private char t;
    public ActionButton(String s){
        super(s);
        name = s;
        t = name.charAt(0);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        ido.newLetter(t);
        this.setEnabled(false);
        LovesMePanel.this.update();
    }

}

the update method:

public void update(){
    answers = ido.getAnswer();
    flower.setTriesLeft(ido.getTriesLeft());
    progress.setText(answers);      
    if(ido.gameOver()){
// This is where I need to deactivate the buttons       
        if(ido.hasWon()){

        }
    }
    else if(triesLeft == 0){

    }

}

the buttons are all created in a loop in the LoveMePanel that holds all of the other panels. Is there a way to reference them all or disable them all when the game is over? If not, how should I change my code so that it would be possible to do that?

See the setEnabled() method for JButton. You can:

  1. Add your Buttons to an ArrayList while creating them and then iterate over it and disable one by one
  2. Get children of a JPanel, iterate over them, check if it's a button and disable it
  3. Put a Glass Pane on top of your Burrons to intercept the incoming events

Feel free to choose the one you like best.

If you put your buttons in a Collection, you can iterate through them and disable them all that way. I.e.,

for (JButton b : myButtons) {
    b.setEnabled(false)
}

If not, you have 26 disable statements to write.

how about getting the children of the root panel by calling getComponents and iterating over them recursively and finding JButtons and disabling them as you find them?
