Swing behavior on splitPane

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,

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.

+1 for JSplitPane inside a JSplitPane, this is the best way to split a SplitPane into 4 parts or more. You also might consider calling .validate() and/or .repaint() to make your jlabels show. – george_h Jun 12 '12 at 10:06
Interesting; that make me wonder if `pack()` was omitted or the layout was used incorrectly. – trashgod Jun 12 '12 at 14:56

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.
