    Default multiple JPanels on one Jscrollpane

    Hi,

    How to make add many JPanels of different sizes one below other to one Jscrollpane?

    I tried something like:


    JFrame frame = new JFrame();
    frame.setSize(1200, 900);
    frame.setResizable(true);
    JScrollPane scrollPane = new JScrollPane();
    ...
    for (Class nnn:nnns)
    {

    ....

    DrawRect drawRect = new DrawRect(nodeList, requests, level); //class that extends JPanel; Preferred size is set dynamically, based on the size of the drawing there

    scrollPane.add(drawRect);
    scrollPane.revalidate();
    }

    frame.getContentPane().setLayout(new BorderLayout());
    frame.getContentPane().add(scrollPane, BorderLayout.CENTER);
    frame.pack();

    frame.setVisible(true);

    Default Re: multiple JPanels on one Jscrollpane

    You should add a JPanel to the JScrollpane's viewport (not directly to the JScrollPane) to act as a container for the other JPanels. Consider giving this JPanel a BoxLayout so that the other JPanels will be placed one below the other. Most important, read the tutorials on use of scrollpanes and layouts. It will explain all the details.
