Moving Appletviewer

[Jonathan Krebs]

Is there any way that I can set the location of Appletviewer on the
screen from within my applet? The move() method does not do the trick.

The following code works for me:

public void centerOnScreen()
{
if( isApplication() )
{
getJTFrame().centerOnScreen();
}
else
{
Dimension screen = getToolkit().getScreenSize();
Frame f = getTopLevelFrame();
Rectangle bounds = f.getBounds();
f.setLocation( (screen.width - bounds.width) / 2, (screen.height - bounds.height) / 2 );
f.setVisible( true );
f.requestFocus();
}
}

private Frame getTopLevelFrame()
{
Component c = getParent();
System.err.println( "component is " + c + "\n" );

while( c.getParent() != null)
{
c = c.getParent();
System.err.println( "component is " + c + "\n" );
}

if( c instanceof Frame)
{
// Note that this is <b>not</b> the browser window.

return (Frame) c;
}
else
{
return null;
}
}
