GridBagLayout problems with align

**lugaru** · December 12th, 2011, 06:52 AM

Hi, guys. Im quite new in Java and specially in GUI. Im using GridBagLayout and I have one problem all my components aligning to center but I need to left and top. How I can do that? How I can set minimum and maximum size of my application(for ex. I have app. with size 500*300 but I want set min. size 400*200 and max. size 600*400)?
Can you give me an advice where I can search and how I can change view of my components (font, size, color, shape)?

public class gui extends JFrame {
        gui(){
            super("Grid Bag L.");
            JFrame frame = new JFrame("test_");
            GridBagLayout g = new GridBagLayout();
            frame.setLayout(g);
            GridBagConstraints c = new GridBagConstraints();
                        frame.setSize(500, 200);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setVisible(true);
 
            String[] w= {"", "", ""};
            JComboBox box= new JComboBox(w);
            g.setConstraints(box,c);
            frame.add(box,new GridBagConstraints(0,0,5,1,0.0,0.0, GridBagConstraints.NORTHWEST, GridBagConstraints.CENTER, new Insets(5,5,5,5),0,0));
 
                         ..................

Please see the following, and note that layouts can be nested (one JPanel with one layout within another with a different layout)

Use GridBagConstraints.anchor property.

component.setMinimumSize(), component.setMaximumSize()
