A DESCRIPTION OF THE PROBLEM :
Dragging JInternalFrames within a JDesktop is extremely slow
and jerky on linux (the problem does not seem to occur under
Windows). Resizing the frame seems to have a similar
problem. The larger the internal frame the less responsive
dragging and resizing becomes.
REGRESSION. Last worked in version 1.3.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. See included example
2.
3.
This bug can be reproduced always.
---------- BEGIN SOURCE ----------
import javax.swing.*;
import java.awt.*;
public class Example extends JFrame {
public static void main(String args[]) { new Example(); }
public Example() {
super("eg");
init();
pack();
setVisible(true);
}
void init() {
// build simple interface
JDesktopPane jdp = new JDesktopPane();
jdp.setPreferredSize(new Dimension(600,600));
jdp.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
setContentPane(jdp);
JInternalFrame jif = new JInternalFrame("boo");
jif.setSize(400, 400);
jif.setVisible(true);
jif.setResizable(true);
getContentPane().add(jif);
}
}
---------- END SOURCE ----------
CUSTOMER WORKAROUND :
None...and without a fix, we cannot release this software
for use on Linux.
Release Regression From : 1.3.1_03
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
