Two linked JTextPanes

I have two JTextPanes with static size and I want to connect them like two pages in text processor. If I write something in the first JTextPane (page) and it will be too long for one JTextPane then it overflow to the second JTextPane (page).

I don’t want something like this (first pane have been expanded):

But I want something like this:

picture 2

There is my testing code:

public class Test2 extends JFrame{
    JTextPane textPane1;
    JTextPane textPane2;

    /**
     * Inicialization
     */
    public Test2() {
        textPane1 = getTextPane();
        textPane2 = getTextPane();

        getContentPane().setLayout(new GridBagLayout());

        getContentPane().add(textPane1,getGridBagConstraints(0));
        getContentPane().add(textPane2,getGridBagConstraints(1));
    }

    /**
     * Settings for text panes
     */
    private JTextPane getTextPane(){
        JTextPane pane = new JTextPane();
        pane.setEditorKit(new WrapEditorKit());
        pane.setMaximumSize(new java.awt.Dimension(100, 108));
        pane.setMinimumSize(new java.awt.Dimension(100, 108));
        pane.setPreferredSize(new java.awt.Dimension(100, 108));
        pane.setBorder(new StrokeBorder(new BasicStroke()));
        return pane;
    }

    /**
     * Setting layout for text panes.
     */
    private GridBagConstraints getGridBagConstraints(int index){
        GridBagConstraints gridBagConstraints = new GridBagConstraints();
        gridBagConstraints.gridx = 0;
        gridBagConstraints.gridy = index;
        gridBagConstraints.anchor = GridBagConstraints.NORTHWEST;
        return gridBagConstraints;
    }

    /**
     * Main
     */
    public static void main(String[] args) { 
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame frame = new Test2();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.pack();
                frame.setVisible(true);
            }
        });
    }

    /**
     * Just class for wrapping text in text panes.
     */
    private static class WrapEditorKit extends StyledEditorKit {
        ViewFactory defaultFactory = new WrapColumnFactory();

        @Override
        public ViewFactory getViewFactory() {
            return defaultFactory;
        }

        private class WrapColumnFactory implements ViewFactory {
            @Override
            public javax.swing.text.View create(Element elem) {
                String kind = elem.getName();
                if (kind != null) {
                    switch (kind) {
                        case AbstractDocument.ContentElementName:
                            return new WrapLabelView(elem);
                        case AbstractDocument.ParagraphElementName:
                            return new ParagraphView(elem);
                        case AbstractDocument.SectionElementName:
                            return new BoxView(elem, javax.swing.text.View.Y_AXIS);
                        case StyleConstants.ComponentElementName:
                            return new ComponentView(elem);
                        case StyleConstants.IconElementName:
                            return new IconView(elem);
                    }
                }

                // default to text display
                return new LabelView(elem);
            }
        }

        private class WrapLabelView extends LabelView {
            public WrapLabelView(Element elem) {
                super(elem);
            }

            @Override
            public float getMinimumSpan(int axis) {
                switch (axis) {
                    case javax.swing.text.View.X_AXIS:
                        return 0;
                    case javax.swing.text.View.Y_AXIS:
                        return super.getMinimumSpan(axis);
                    default:
                        throw new IllegalArgumentException("Invalid axis: " + axis);
                }
            }
        }
    }
}

Any ideas pleas? I’ve tried many things, but nothing worked.

Looks like you need pagination See java-sl.com/Pagination_In_JEditorPane.html and may be all the 4 articlaes about pagination features (see here java-sl.com/articles.html ) – StanislavL Dec 15 ’14 at 8:00
