I am noticing a flickering problem when initially displaying a JWindow.
It always flashes white before displaying the correct background color.
In fact it appears to go white, bgcolor, white, and then bgcolor all in
a split second. I tested on two different machines (P333 and a P2-400)
and both show the same flickering.
Is this a know problem or am I not doing something quite right? I
searched the Java bug database, but could not find an entry regarding
this issue. The code below creates a full screen JWindow which always
flickers on initialization.
-Sean
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class WindowTest implements ActionListener
{
JWindow win;
Container content;
JButton quitButton;
public WindowTest()
{
win = new JWindow();
content = win.getContentPane();
content.setLayout(null);
Dimension screenResolution = win.getToolkit().getScreenSize();
win.setSize(screenResolution);
content.setBackground(Color.darkGray);
// Quit Button
quitButton = new JButton("quit");
quitButton.setSize(70,40);
quitButton.setLocation(500, 500);
quitButton.addActionListener(this);
content.add(quitButton);
win.show();
}
public void actionPerformed(ActionEvent e)
{
Object src = e.getSource();
if (src.equals(quitButton))
{
System.exit(0);
}
}
static public void main(String[] args)
{
WindowTest w = new WindowTest();
}
}
