You should consider using setPreferredSize instead of setSize for your
components. If you don't use swing, implement getPrefferedSize. Read
more about layout managers . They have the last word about the size of a
component. Either if you call setSize before or after adding a component
to a container, the size of the component is not completely determinate.
No wander you got different results on different platforms.
Here is an example with getPrefferedSize which will work on all platforms:
----------- Cut here -------------------
import java.awt.*;
import javax.swing.*;
public class TestFrame extends JFrame {
TestFrame() {
super();
JPanel c = new JPanel();
c.setPreferredSize(new Dimension(800, 600));
getContentPane().add(c); //default layout is BorderLayout
}
public static void main(String[] args) {
TestFrame tf = new TestFrame();
tf.pack();
tf.show();
}
}
----------- Cut here -------------------
