Java: Adding panel inside another at run time to fit visible area

Question

In my application I want to show generated graph, using JUNG. It produces JPanel object as output. So, i though it would be just a matter of adding a component to panel. But the graph is drawn outside of its parent panel. Screenshot: How do I restrict the graph to be only inside the visible area? The code I use to add graph to panel is this (the border was for me to see panel borders, though it doesnt show for some reason):

    Layout<Object, String> layout = new CircleLayout<Object, String> (graphProvider.getGraph());
    layout.setSize(panel.getMarketGraphPane().getPreferredSize());
    BasicVisualizationServer<Object,String> graphPanel = new BasicVisualizationServer<Object,String>(layout);
    graphPanel.setBorder(new EtchedBorder());
    graphPanel.setSize(panel.getMarketGraphPane().getPreferredSize());
    panel.getMarketGraphPane().add(graphPanel, BorderLayout.CENTER);
    panel.getMarketGraphPane().revalidate();

Answer 1

use GraphZoomScrollPane to add zoom-able graph scrollpane container for VisualizationViewer object as follows:

GraphZoomScrollPane pane = new GraphZoomScrollPane(visualizationViewer);
JPanel panel = new JPanel();
BorderLayout panelMapLayout = new BorderLayout();
panel.setLayout(panelMapLayout);
panel.add(pane, BorderLayout.CENTER);

Answer 2

too little informations for the actual image

1 depends

• what Size returns (generated graph, by using JUNG), are you set there setSize(int, int) too,

• if is graph resiziable,

2) remove

• layout.setSize(panel.getMarketGraphPane().getPreferredSize());

and

• graphPanel.setSize(panel.getMarketGraphPane().getPreferredSize());

you can't to setSize for Object placed to the BorderLayout.CENTER, and I think that is possible directly put (generated graph, using JUNG. It produces JPanel object) to the BorderLayout.CENTER area, try that maybe your twice setSize generated some mess

and then you can call only

panel.add(graphPanel, BorderLayout.CENTER);
panel.revalidate();
panel.repaint();

3) another two choises (without clean-up setSize)

• call pack(); to the Top-Level Container, notice carefully with LCD/LED monitors bounds

• put that to the JScrollPane
