求一个swing布局代码

里面的东西不要，只要这样的布局的代码。右边有tabpanel，左边一个空panel
右边的panel里面切分成4小块。分别4个panel

[code="java"]JPanel rightPanel = new JPanel();
//rightPanel.setLayout(new GridLayout(4,1,5,5));
rightPanel.setLayout(new BoxLayout(rightPanel,BoxLayout.PAGE_AXIS));
//rightPanel.add(...);
//...
JTabbedPane leftPanel = new JTabbedPane();
// leftPanel.add...
JSplitPane mainPanel = new JSplitPanel(JSplitPane.HORIZONTAL_SPLIT,leftPanel,rightPanel);[/code]
