How to put a component on top of others?

I have a JScrollPanel that includes a big panel which it's self includes 3 inner panels. i want to put a panel (for example) in a special place so that always could be seen, I mean the user can scroll to anywhere wants but that panel always is in top of the other components and doesn't move. I tried to do that via JLayeredPane but I couldn't. how may I do that?

Solution

  • There's a JLayeredPane example here, but OverlayLayout, seen here, may be of interest. It's not included in the conventional gallery.

    OverlayLayout

    Also consider this example that paints on the scroll pane's JViewport.
