Creating a simple design in java using GrigBagLayout without using swing

I want to create this design using only GrigBagLayout without using swing and panel in this code.

Inorder to complete my assignment problem i just prepare the code for this this design but it is not perfectly arranged.

import java.awt.*;
class GridBagLayout {
    public static void main(String args[]) {

        Frame f = new Frame();
        f.setSize(400,600);
        f.setLayout(new GridLayout());
        GridBagConstraints gbc = new GridBagConstraints();

        Label l = new Label("Name  ");
        gbc.gridx=1;        
        gbc.gridy=1;
        f.add(l,gbc);


        TextField t = new TextField();
        gbc.gridx=1;            
        gbc.gridy=0;
        f.add(t,gbc);


        Label l2 = new Label("Password ");
        gbc.gridx=0;                    
        gbc.gridy=1;
        f.add(l2,gbc);

        TextField t2 = new TextField();
         gbc.gridx=1;           
         gbc.gridy=1;
        f.add(t2,gbc);


        Button b = new Button("OK");
        gbc.gridx=1;
        gbc.gridy=1;
        f.add(b,gbc);

        f.setVisible(true);
    }
}

So anyone can tell me about where my code is lacking to perfectly arranged.

Solution

  • I hope your Assignment work should be based on GridBagLayout

    GridBagLayout

    so why you are using

    • f.setLayout(new GridLayout());

    Instead of using correct Layout

    f.setLayout(new GridBagLayout);

    import java.awt.*;
    class GridBagLayout
    {
        public static void main(String[] args) {
            Frame f=new Frame();
            f.setSize(300,200);
            GridBagLayout gl = new GridBagLayout();
            f.setLayout(gl);
            GridBagConstraints g=new GridBagConstraints();
            g.gridx=0;
            g.gridy=0;
            f.add(new Label("Name") , g);

            g.gridy=1;
            f.add(new Label("Password") , g);

            g.gridx=1;
            g.gridy=0;
            f.add(new TextField(15) , g);

            g.gridy=1;
            g.gridx=1;
            f.add(new TextField(15) , g);       

            g.gridx=0;
            g.gridy=2;
            g.gridwidth=2;
            g.insets = new Insets(30,0,0,0);
            f.add(new Button("OK"),g);

            f.setVisible(true);
        }
    }

    As GridBagLayout divides a container into a grid of equally sizwd cells and it requires lot of information to know where to put a component that's why i used gridx/y ,insets etc for proper arrangements of your labels and texfields.
