Question

在寻找解决方案时，我在StackOverflow的所有答案中找到了几乎相同的想法。但是所有这些都没有用，我需要帮助我找到代码特殊部分的解决方案。

//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);

结果是，thers在maingui中不是JFrame。（没有SCrollPane解决方案，它正确地适用）

Answer 1

完全删除editorScroll变量并替换

     mainTabs.addTab("Editor", editorScroll);

带

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

它应该有用......

使用JScrollPane和JPanel创建可滚动的JFrame
