splitPane上的摇摆行为

Question

  JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
             scrollPane , scrollPane2);

I want to do very trivial action and I it doesn't work.

Whenever I add label to either of scrollPanes - they simply don't display anything. I can display tables within panes but these are added through the constructor. Pisses a lot.

Also if splitPane only allows two components - what if I want to separate window into four parts? SplitPane of SplitPane?

Thanks for help,

Answer 1

You might compare your implementation to this example that adds a JLabel instance to a JPanel on each side of the JSplitPane .

Although JSplitPane only admits two components, you can add another JSplitPane to either pane in order to subdivide either side in either direction, ad libitum .

Answer 2

Don't forget to call updateUI() after you've added your components. JSplitPane is really only supposed to be used for splitting into two components. If you require more, consider using a TableView .
