Swing's components and Graphics2D.scale

[Tomek Tajne]

Hello,

I have image and Swing components in my panel and I'm trying to resizing it by using Graphics2D.scale(int, int), but Swing's component aren't looking properly after that.
See what's happen with JButton and JLabel after using Graphics2D.scale.
How can I fix it?

import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
 
public class Test{
    public static void main(String args[]){
        EventQueue.invokeLater(new Runnable(){public void run(){
            JFrame ramka=new JFrame();
            ramka.setSize(300,200);
            ramka.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            ramka.add(new panel());
            ramka.setVisible(true);
        }});
    }
}
 
class panel extends JPanel{
    panel(){
        this.setLayout(null);
        JTextField tekst=(new JTextField("Test"));
        tekst.setBounds(40, 40, 50, 30);
        add(tekst);
 
        JButton przycisk=new JButton("Test");
        przycisk.setBounds(100, 40, 70, 30);
        add(przycisk);
    }
 
    public void paintComponent(Graphics g){
        Graphics2D g2=(Graphics2D)g;
        g2.scale(1.5, 1.5);
        g2.fillRect(50,70,10,10);
    }    
}

Why don't you just call setPreferredSize() on your components? That is the more 'correct' way of doing it. Generally you shouldn't be messing with the way in which Swing components are painted.

I'm trying to resize view of whale panel with a big image and many Swing Components. There is no image in the code I've pasted above, but there is a rectangle instead.
I need buttons with zoom in/zoom out options, and I though that using Graphics2D.scale would be the best option, because Image.getScaledInstance takes too much time
Do you know how to fix this code?
