A Boolean that indicates whether the browser cell is a leaf or a branch cell.
Declaration
var isLeaf: Bool { get set }Discussion
When the value of this property is true, the browser cell is a leaf cell.
A branch NSBrowserCell has an image near its right edge indicating that more, hierarchically related information is available; when the user selects the cell, the NSBrowser displays a new column of NSBrowserCell objects. A leaf NSBrowserCell has no image, indicating that the user has reached a terminal piece of information; it doesn’t point to additional information.
