Updating location of JPanel

im currently working on a game in Java and a problem occured. It is a strategy game.

My game area or map is a JPanel, which i put in a JScrollPane, allowing you to scroll around the map. I put other JPanels on the map, for example a bar for info about your current resources. Of course when i scroll, theese JPanels doesnt follow, and now i wonder whats my best tactic for this?

For now, im using the keyboard arrows to scroll, i then use setBounds of the JPanels i wanna move in the same direction. For example , for the right arrow key i increase the value of the x value in the setBounds parameter (x, y, sizeX , sizeY). This isnt very pretty and if u hold the right arrow key for some seconds, the JPanel which has an image, starts flickering a bit.

What are my options? Thanks for your time!

I would put the "resources"-bars etc outside of the scroll panel. I.e., let the main panel have a BorderLayout and let the map-area be the center component, and put the resources-bar as south component.

      Main panel (BorderLayout)
