Create scrollable JFrame using JScrollPane and JPanel

Question

As looking for a solution, i found almost the same idea in all answers in StackOverflow. But all did not work, i need to help me for a solution for that special part of code.

//Create a JTabbedPane for 2 tabs
mainTabs = new JTabbedPane(JTabbedPane.TOP);

//Create the first tab
reportingTabs = new JTabbedPane(JTabbedPane.TOP);

// editor is an object created from a class inherited form JPanel
editor = new GraphEditor();

//Create a JMenuBar
EditorMenuBar menuBar = new EditorMenuBar(editor);

//Create a JFrame for the editor
editorFrame = editor.createFrame();


//Create a JPanel object to contain bothe the JMenubar and the editor JFrame
JPanel editorPanel = new JPanel(new BorderLayout());

//Here the solution, creating a JScrollPane to contain only the editor JFrame to be scrolled
JScrollPane editorScroll = new JScrollPane();

//Adding the JMenuBar and the editor JFrame to the JPanel
editorPanel.add(menuBar, BorderLayout.NORTH);
editorPanel.add(editorFrame.getContentPane());

//Involve the JPanel into the JScrollPane
editorScroll.add(editorPanel);


//Adding the tabs to the main JFrame
maingui.getContentPane().add(mainTabs);

//Adding the JScrolledPane to a tab
mainTabs.addTab("Editor", editorScroll);

The result, is that thers is no JFrame in maingui. (with no SCrollPane solution, it appreas correctly)

Answer 1

Remove editorScroll variable completely and replace

     mainTabs.addTab("Editor", editorScroll); 

with

     mainTabs.addTab("Editor", new JScrollPane(editorPanel));

It should work...
