这里面包含了一百多个JAVA源文件

// Create a read-only combobox
    String[] items = {"item1", "item2"};
    JComboBox readOnlyCB = new JComboBox(items);

By default, a combobox only allows the user to select from a predefined list of values. The combobox can be made editable which not only allows the user to select from the predefined list but also to type in any string. 
    // Create an editable combobox
    items = new String[]{"item1", "item2"};
    JComboBox editableCB = new JComboBox(items);
    editableCB.setEditable(true);
