So far I managed to avoid using the GridBagLayout (by hand code) as much as possible, but I could not avoid it this time and I am reading the SUN's tutorial GridBagLayout So far it is not going well. I think I am missunderstanding something. For example I try the following code (similar to the one in SUN's post): public class MainFrame extends JFrame { public static void main(String args[]) { EventQueue.invokeLater(new Runnable() { public void run() { try { MainFrame frame = new MainFrame(); frame.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } }); } /** * Create the frame */ public MainFrame() { super(); setBounds(100, 100, 500, 375); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container mainContainer = getContentPane(); mainContainer.setLayout(new GridBagLayout()); //add label JLabel someLabel = new JLabel("Label 1:"); GridBagConstraints constraints = new GridBagConstraints(); constraints.gridx = 0; constraints.gridy = 0; //constraints.anchor = GridBagConstraints.FIRST_LINE_START; //constraints.weightx = 0.5; mainContainer.add(someLabel, constraints); JTextField someText = new JTextField(30); constraints = new GridBagConstraints(); constraints.gridx = 1; constraints.gridy = 0; constraints.weightx = 0.5; mainContainer.add(someText, constraints); // } } I get the label and the textfield one next to the other in the center of the frame. But I was expecting that they would show up in the top left corner since the gridx and gridy
