Can a GUI be created with certain button sizes and textfield sizes so that some buttons are sized larger than others, I know it can be done with VB but I don't know about Java, can anyone help?

import java.awt.*;
import java.util.*;
import javax.swing.*;
 
public class NoWorriesMate{
    
    public static void main(String[] args) {
        Box box = Box.createHorizontalBox();
        for(int i=0; i<10; ++i)
            box.add(createButton());
        JFrame f = new JFrame("NoWorriesMate");
        f.setContentPane(box);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }
 
    static JButton createButton() {
        JButton btn = new JButton("I'm resized");
        final int pad = 10;
        btn.setMargin(new Insets(pad, pad, pad, pad));
        return btn;
    }
}

This is an example for making a certain size buttons. It's simple, try searching google for the other one. Google is a coder's best friend

The set___Size() methods will do it for you too.

(Toggle Plain Text)

public class SizedButtons extends JFrame{

  public SizedButtons(){
    
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    
    JPanel panel = new JPanel();
    BoxLayout layout = new BoxLayout(panel, BoxLayout.Y_AXIS);
    panel.setLayout(layout);
    
    panel.add(makeBtn(500, 10));
    panel.add(makeBtn(70, 70));
    panel.add(makeBtn(60, 300));
    
    add(panel);
    pack();
    setVisible(true);
    
  }
 
  private JButton makeBtn(int width, int height){
    JButton btn = new JButton(Integer.toString(width) + " x " + Integer.toString(height));
    btn.setMinimumSize(new Dimension(width, height));
    btn.setMaximumSize(new Dimension(width, height));
    btn.setPreferredSize(new Dimension(width, height));
    btn.setMargin(new Insets(0, 0, 0, 0));
    return btn;
  }
  
  public static void main(String[] args){
    new SizedButtons();
  }
}

EDIT: As an additional note, setMargins(Insets) only changes the spacing between the edges of the button and its contents. So, in order to predict the final size of the button you have to know the exact size of the contents inside. On the other hand, if you use the set____Size() methods, you'll be guaranteed to get the exact size you want. (And you can still control the margins if you want. I set them all to zero to make sure the text would still show up in smaller buttons. When there isn't enough room, text is converted to an ellipsis.) As a general rule, try to use all three of the sizing methods. Sometimes setPreferredSIze() (the most important of the three) isn't enough. Oh, and you can't set the size of objects that are in the center position of a BorderLayout, just so you know. Objects placed there always stretch to fill the entire center space.

what classes will I need to import to use this code?

squishiful · Jun 23rd, 2005, 12:47 PM

never mind I figured it out:

import javax.swing.*;
import java.awt.*;

If you want to set the exact location and size of a component use the following code:

(Toggle Plain Text)

//imports
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JButton;
import java.awt.Component;

//code
JPanel pnl = new JPanel();
pnl.setLayout(null);
JButton btn = new JButton();
//sets the size and location of a component
//[component].setBounds(int x, int y, int width, int height);
btn.setBounds(50, 50, 100, 30);
pnl.add(btn);
add(pnl);

Very helpful if you want absolute control.
