Language Version: ActionScript 3.0

The SelectionState class represents a selection in a text flow.

A selection range has an anchor point, representing the point at which the selection of text began, and an active point, representing the point to which the selection is extended. The active point can be before or after the anchor point in the text. If a selection is modified (for example, by a user shift-clicking with the mouse), the active point changes while the anchor point always remains in the same position.

SelectionState

()Constructor
public function SelectionState(root:flashx.textLayout.elements:TextFlow, anchorPosition:int, activePosition:int, format:flashx.textLayout.formats:ITextLayoutFormat = null)

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Creates a SelectionState object.

Note: Do not construct a SelectionState object in order to create a selection. To create a selection in a text flow, call the setSelection() method of the relevant ISelectionManager instance (which is the SelectionManager or EditManager object assigned to the interactionManager property of the text flow).

Parameters
root:flashx.textLayout.elements:TextFlow — The TextFlow associated with the selection.
 
anchorPosition:int — The anchor index of the selection.
 
activePosition:int — The active index of the selection.
 
format:flashx.textLayout.formats:ITextLayoutFormat (default = null) — The TextLayoutFormat to be applied on next character typed when a point selection
