How do you change the preferredSize() of a java program, after setVisible()? For example, you have a program that is 100x200, but when you click a button it changes to something else like 300x100.
Thanks in advance for any help.

you have probably to call the repaint() method – René Winkler Apr 18 '16 at 18:24

@RenéWinkler already tried that, along with revalidate(), neither worked – Ryan Apr 18 '16 at 18:27

How do you setting size to 100x200? Do you talking about size of a `JFrame`. – rdonuk Apr 18 '16 at 18:42

@Reşit Dönük yes, I would like to change the size of the JFrame to a different size, after I called setVisible(true) – Ryan Apr 18 '16 at 18:57

`setSize()` should be work. – rdonuk Apr 18 '16 at 18:58

@ReşitDönük ok, that worked, but why did that work and `setPreferredSize()` didn't? – Ryan Apr 18 '16 at 19:11

Becasue they are different methods. Read [here](http://stackoverflow.com/questions/1783793/java-difference-between-the-setpreferredsize-and-setsize-methods-in-compone) for more information. – rdonuk Apr 18 '16 at 19:14

@ReşitDönük Thanks you very much – Ryan Apr 18 '16 at 19:16

Assuming you called setVisible method like this
new MyWindow().setVisible(true);
And your button's click event name is myButtonActionPerformed, then this code will work:
private void myButtonActionPerformed(java.awt.event.ActionEvent e) {
setSize(new java.awt.Dimension(300, 100));
}
