.setIconImage(); to all frames instead one by one

Question

How can i set an Icon for all frames that will exist in my application? I don't want to use frame.setIconImage(0); frame1.setIconImage(1); etc. every time i create a frame.

Best Regards, Marek

If my main class extends JFrame - do i have to create another subclass? Because if i put `this.setIconImage(Icon);` in my constructor - it doesn't work. @Brian — Marek, Oct 16 '14 at 19:26

make a class which extends jframe .

public class customFrame extends JFrame{

    public customFrame() {
        try {
            this.setIconImage(ImageIO.read(new File("C:\\Users\\Madhawa.se\\Desktop\\gtg.PNG")));
        } catch (IOException ex) {
            Logger.getLogger(customFrame.class.getName()).log(Level.SEVERE, null, ex);
        }
    }


}

now when you create jframes extends that class[frame] instead jframe.

like follow ;

public class frame1 extends customFrame{
    public static void main(String[] args) {
        new frame1().setVisible(true);

    }
}

next frame so on..

public class frame2 extends customFrame{
    public static void main(String[] args) {
        new frame2().setVisible(true);

    }
}

and also you can make frames like follow

public static void main(String[] args) {
    customFrame frame1 = new customFrame();
    frame1.setTitle("title");
    frame1.add(new JLabel(""));
    frame1.setVisible(true);
}

except one thing. Now when i call `customFrame frame = new customFrame("I can't give this title");` – Marek Oct 16 '14 at 19:42
@jotto Then make another constructor to take the title and call the frames super method... – MadProgrammer Oct 16 '14 at 19:43
@jotto or you can call frame.setTitle("but I can give this title");you should use setters – Madhawa Priyashantha Oct 16 '14 at 19:46
getlost, i wanted to get rid of .setIconImage, and now i would have to add .setTitle(); so it would bring more code again. But thank you. You've been very helpful. – Marek Oct 16 '14 at 19:50
@jotto yes it's better create a constructor so you can easily set title . – Madhawa Priyashantha Oct 16 '14 at 19:53

While you could extend JFrame and create a custom implementation, you're not really adding much new functionality to the frame , which could come, back and haunt you latter.

Another approach would be to create a frame factory, which could be used to generate the frame the way you want it. This would allow you to create a series of methods to meet your needs.

It also means you can change the way the factory methods work without having to change any of the other code...

public class FrameFactory {
    public static JFrame createDefaultFrame() {
        JFrame frame = new JFrame();
        frame.setIconImage(ImageIO.read(...)));
        return frame;
    }

    public static JFrame createFrameWithTitle(String title) {
        JFrame frame = FrameFactory.createDefaultFrame();
        frame.setTitle(title);
        return frame;
    }
}

.setIconImage(); to all frames instead one by one
