Question

I am just trying to add 3 centered vertical buttons to a GridBagLayout in java swing. Right now I believe the default grid size is 3×3. I wanted to know if I can change that and add more columns and rows. I simply want to make 3 centered equally spaced butons in a pane.

    pane.setLayout(new GridLayout(10,1));
    // Insert a space before the first button
    for (int i = 1; i < 6; i++ ){
        pane.add(new JLabel(""));
    }
    pane.add(new Button("1"));
    pane.add(new Button("2"));
        pane.add(new Button("3"));
    // Insert a space after the last button
    pane.add(new JLabel(""));

That was the final solution Thanks everyone!

I agree with @Chris a GridLayout would be easier:

myPanel.setLayout(new GridLayout(5,1));
// Insert a space before the first button
add(new JLabel(""));
add(new Button("1"));
add(new Button("2"));
add(new Button("3"));
// Insert a space after the last button
add(new JLabel(""));
