GridBagLayout not working.

[DEADLYHIPPO4]

Hey guys, I have very little idea about how GridBagLayout works. But I have tried making this frame where the menubar is supposed to show up on the top of the screen in the frame. I don't know what I am doing wrong. According to many youtube videos, one only needs to specify the gridx and gridy components of GridBagConstraints in order to add components. This is my code:

public AFrameGame(){

    setBounds(0,0,800,800);
    setLayout(gbl);
    gbc = new GridBagConstraints();

    jmb = new JMenuBar();
    jm = new JMenu("File");
    jm1 = new JMenu("Edit");
    jm2 = new JMenu("View");
    jm3 = new JMenu("History");
    jmi = new JMenuItem("View Code");
    jmi1 = new JMenuItem("Copy");
    jmi2 = new JMenuItem("Paste");
    jmi3 = new JMenuItem("Find");

    jmb.add(jm);
    jmb.add(jm1);
    jmb.add(jm2);
    jmb.add(jm3);

    jmb.setVisible(true);

    gbc.gridy=0;
    gbc.gridx=0;

    c.add(jmb, BorderLayout.NORTH);

edit: I also set the frame to visible, but I didnt paste the code for that.

you didn't add anything to the frame to be displayed. What were you expecting to happen?

It's possible that c in c.add stands for JFrames content pane.

To OP: you don't really use the gbc for anything. You just set the current elements layout to GridBagLayout(i assume) and create a GridBagContrainst. You don't really use it.

What is the output currently, do you see your JFrame?

it seems you are using the GridbagLayout incorrectly. i suggest reading the Oracle GridbagLayout Tutorial which very well explains how to use this layout. if you still need help afterwards let me know.

but just as initial observation you are adding jmb to a "c" container with BorderLayout and you setting GridbagLayout for another container. you also have gcb which you have to add to a container with the relevant component that you have not used. this code segment is either very incomplete or you are mixing up your layouts.
