Question

I have a dual monitor config and I want to run my GUI in a specific monitor if it is found. I tried to create my JFrame window passing a GraphicConfiguration object of my screen device, but it doesn't work, frame still display on the main screen.

How can I set the screen where my frame must be displayed?

Answer 1

public static void showOnScreen( int screen, JFrame frame )
{
    GraphicsEnvironment ge = GraphicsEnvironment
        .getLocalGraphicsEnvironment();
    GraphicsDevice[] gs = ge.getScreenDevices();
    if( screen > -1 && screen < gs.length )
    {
        gs[screen].setFullScreenWindow( frame );
    }
    else if( gs.length > 0 )
    {
        gs[0].setFullScreenWindow( frame );
    }
    else
    {
        throw new RuntimeException( "No Screens Found" );
    }
}
