[Bug swing/17360] JScrollPane has incorrect size when JList with specified size is added to it
--- Comment #4 from abalkiss at redhat dot com 2005-10-26 15:23 ---
This appears to be a problem with JScrollPane.getPreferredSize(), as the
FlowLayout sets the size of the JScrollPane to its preferredSize, and then this
is a bound for the layout in ScrollPaneLayout which then sets an inappropriate
size for the JViewport.
The simple testcase below shows that JScrollPane is returning an inappropriate
value for getPreferredSize.
***TESTCASE***
import java.awt.*;
import javax.swing.*;
class Test2
{
public static void main(String[] args)
{
JFrame f = new JFrame();
String[] items =
{
Item1, Item2, Item3, Item4, Item5, Item6,
Item7, Item8, Item9, Item10, Item11
};
JList list = new JList(items);
list.setPreferredSize(new Dimension(150, 150));
f.setLayout(new FlowLayout());
JScrollPane scroller = new JScrollPane(list);
System.out.println (scroll pane pref size: +scroller.getPreferredSize());
}

An even more specific test case shows that the problem is in ScrollPaneLayout's
preferredLayoutSize method.
***TESTCASE***
import java.awt.*;
import javax.swing.*;
class Test
{
public static void main(String[] args)
{
String[] items =
{
Item1, Item2, Item3, Item4, Item5, Item6,
Item7, Item8, Item9, Item10, Item11
};
JList list = new JList(items);
list.setPreferredSize(new Dimension(150, 150));
JScrollPane scroller = new JScrollPane(list);
System.out.println (scroller.getLayout().preferredLayoutSize(scroller));
}
}

[Bug SWING/22151] New: JInternalFrame causes OutOfMemory error when maximized.
JInternalFrame causes OutOfMemory error when maximized.
Run the test case below, maximize the JInternalFrame, wait a while. OutOfMemory
error.
When the JInternalFrame is positioned at (10,10) rather than (60,60) the error
doesn't occur.
==TEST CASE==
import java.awt.*;
import javax.swing.*;
import java.io.*;
public class OutOfMemory {
public static void main(String[] a) throws IOException{
JFrame myFrame = new JFrame(Outer);
myFrame.setSize(300,300);
myFrame.setContentPane(new JDesktopPane());
JInternalFrame f = new JInternalFrame(Internal);
f.setSize(200,200);
f.setVisible(true);
f.setClosable(true);
f.setMaximizable(true);
f.setResizable(true);
f.setIconifiable(true);
/* IF THE FOLLOWING LINE IS CHANGED TO f.setLocation (10,10)
no OutOfMemory error occurs! */
f.setLocation(60,50);
myFrame.add(f);
myFrame.setVisible(true);
}
}
