TreeEditor: editable tree GUI component

TreeEditor is a Java GUI component for editing tree structure.  It is a JScrollPane (as of TreeEditor ver. 0.1.0) derived and you can directly embed the component in your app.  I would suggest using JSplitPane.

First and foremost, load the TreeEditor-0.1.5 library (if you are using Maven) as follows.

        <dependency>
            <groupId>com.github.easai.utils</groupId>
            <artifactId>TreeEditor</artifactId>
            <version>0.1.6</version>
        </dependency>

Instantiate TreeEditor with a file name (or an empty string).    Initialize it by calling TreeEditor#init().  Here I put it in a JSplitPane and the TreeEditor will be resizable as the pane resizes.

    TreeEditor treeEditor = new TreeEditor("");

    JTextArea menuCode = new JTextArea();
    JTextArea listenerCode = new JTextArea();

    public void init() {
        treeEditor.init();

        JSplitPane horizPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
        horizPane.setLeftComponent(treeEditor);

        horizPane.setDividerLocation(500);
        JSplitPane rightPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
        rightPane.setTopComponent(new JScrollPane(menuCode));
        rightPane.setBottomComponent(listenerCode);
        rightPane.setDividerLocation(500);

        horizPane.setRightComponent(rightPane);

        getContentPane().add(horizPane);

        setSize(1300, 900);
        setVisible(true);
        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    }

Here is a screen shot of the app. The left pane contains the TreeEditor component. Now you can process any tree structured data from the editor.
