fillRect not showing up

I have a problem with drawing a rect on screen. I have the paintComponent method in my jpanel class and I want to draw a rect in it. It looks like this:

public void paintComponent( Graphics g ) {

    super.paintComponent( g );

    g.setColor( Color.yellow );
    g.fillRect( 0, 140, 100, 100 );

}

The problem is that I have a couple of panels added to the one that I'm drawing in. The subpanels always show up on top and the rect is drawn beneath them. How can I make it so that the rect is drawn in front?

No offense, but I feel this is a bad idea...

public void paint( Graphics g ) {

    super.paint( g );

    g.setColor( Color.yellow );
    g.fillRect( 0, 140, 100, 100 );

}

As Hovercraft has pointed out, a better approach would be to use a GlassPane (How to use RootPanes) or a JLayeredPane or JLayer (AKA JXLayer if you're not using Java 7)

If the drawn JPanel is in the container, then there's no way that it can be in "front". You can make the child components non-opaque by calling setOpaque(false) on them, but still the container will always be behind its children.

If you absolutely want a component above another, consider using a JLayeredPane or consider drawing on the top level window's glass pane.
