I am trying to add a JButton array that I added to a panel onto my JFrame, yet nothing is showing up

Question

Here is my code: For some reason nothing will appear on my screen, yet I don\'t know why, I believe I am initializing it correctly and adding it. Help?

import j         


        

Answer 1

Call mainFrame.setVisible(true); last

private void Start()
{

    JFrame mainFrame = new JFrame("MineSweeper");
    // Move this...
    //mainFrame.setVisible(true);
    //...
    mainFrame.add(p1, BorderLayout.CENTER); 
    // To here
    mainFrame.setVisible(true);
}

You should also launch you application with the context of the EDT. Take a look at Initial Threads for more details

You should also avoid using a MouseListener on buttons, they have a ActionListener API which includes notification when the use clicks the button or "active" key (usually Enter or Space)
