Tree.getSelection介绍

[英]Returns an array of TreeItems that are currently selected in the receiver. The order of the items is unspecified. An empty array indicates that no items are selected.

Note: This is not the actual structure used by the receiver to maintain its selection, so modifying the array will not affect the receiver.
