Resize JButtons in a BoxLayout

boxlayout, java, jbutton, swing

Solution

As an example, to change the size of the "Start" button,

change :

    start1 = new JButton("Start");

to

    start1 = new JButton("Start") {
        {
            setSize(150, 75);
            setMaximumSize(getSize());
        }
    };

Problem

I'm trying to make a simple menu for my game. I have 4 buttons in the center and I want to make them a little bit bigger and center them. The last part worked but I can't seem to call any of my `JButtons` and do a `.setSize` / `.setPreferedSize(new Dimension())` on it. ``` public class mainMenu extends JFrame { private JButton start, highscore, help, stoppen; public mainMenu() { super("Master Mind"); maakComponenten(); maakLayout(); toonFrame(); } private void maakComponenten() { start = new JButton("Start"); start.setBackground(Color.gray); highscore = new JButton("Higscores"); help = new JButton("Help"); stoppen = new JButton("Stoppen"); } private void maakLayout() { JPanel hoofdmenu = new JPanel(); hoofdmenu.setLayout(new BoxLayout(hoofdmenu, BoxLayout.Y_AXIS )); hoofdmenu.add(start); start.setAlignmentX(CENTER_ALIGNMENT); hoofdmenu.add(highscore); highscore.setAlignmentX(CENTER_ALIGNMENT); hoofdmenu.add(help); help.setAlignmentX(CENTER_ALIGNMENT); hoofdmenu.add(stoppen); stoppen.setAlignmentX(CENTER_ALIGNMENT); super.add(hoofdmenu); } private void toonFrame() { setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); setVisible(true); setSize(500,500); } public static void main(String[] args) { new mainMenu(); } } ```
