Forward searches for the string “Matisse” in the item at index 5, then if necessary at index 0, index 1, and so on. These arrows let the user collapse and then expand either of the components with a single click. Many list selection events can be generated from a single user action such as a mouse click.
The minimum size of each SizeDisplayer is indicated by a bright blue rectangle. Now that you’ve seen the default behavior of split panes, we can tell you what’s happening behind the scenes and how you can affect it.
