Class | public class SelectionManager |
Inheritance | SelectionManager ![]() |
Implements | ISelectionManager |
Subclasses | EditManager |
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 10, AIR 1.5 |
The selection manager keeps track of the selected text range, manages its formatting,
and can handle events affecting the selection. To allow a user to make selections in
a text flow, assign a SelectionManager object to the interactionManager
property of the flow. (To allow editing, assign an instance of the EditManager class,
which extends SelectionManager.)
The following table describes how the SelectionManager class handles keyboard shortcuts:
