How to set component background color in JGraphX?

Question

I want to create the background of a JGraphX ​​graph component ( https://github.com/jgraph/jgraphx ) of a specific color. I tried a standard call for any Swing component:

graphComponent.setBackground(Color.BLACK);

but it has no effect. I also tried to get the component to be repainted, no luck. Wrong call or is there any specific way to force update?

Since mxGraphComponentextends JScrollPanewill change the background of the view port:

graphComponent.getViewport().setOpaque(true);
graphComponent.getViewport().setBackground(Color.BLACK);

From JScrollPane docs:

, , scrollPane.getViewport(). setBackground(). , scrollpane - , JViewport , , , , , , . , JScrollPane , , , .
