ISelectionManager  - AS3

The text position of the end of the selection, as an offset from the start of the text flow.

The absolute end is the same as either the active or the anchor point of the selection, whichever comes last in the text flow.

The text position of the start of the selection, as an offset from the start of the text flow.

The absolute start is the same as either the active or the anchor point of the selection, whichever comes first in the text flow.

The active point of the selection.

The active point is the volatile end of the selection. The active point is changed when the selection is modified. The active point can be at either the beginning or the end of the selection.

The anchor point of the selection.

An anchor point is the stable end of the selection. When the selection is extended, the anchor point does not change. The anchor point can be at either the beginning or the end of the selection.

The current SelectionFormat object.

The current SelectionFormat object is chosen from the SelectionFormat objects assigned to the unfocusedSelectionFormat, inactiveSelectionFormat and focusedSelectionFormat properties based on the current state of the windowActive and focused properties.

The editing mode.

The editing mode indicates whether the text flow supports selection, editing, or only reading. A text flow is made selectable by assigning a selection manager and editable by assigning an edit manager. Constants representing the editing modes are defined in the EditingMode class.

Indicates whether a container in the text flow has the focus.

The focused property is true if any of the containers in the text flow has key focus.

The SelectionFormat object used to draw the selection in a focused container.

The SelectionFormat object used to draw the selection when it is not in the active window.

The TextFlow object managed by this selection manager.

A selection manager manages a single text flow. A selection manager can also be assigned to a text flow by setting the interactionManager property of the TextFlow object.

Related API Elements

The SelectionFormat object used to draw the selection when it is not in a focused container, but is in the active window.

Indicates whether the window associated with the text flow is active.

The windowActive property is true if the window displaying with the text flow is the active window.

Executes any pending FlowOperations.

The execution of some editing operations, such as text insertion, is delayed until the next enterFrame event. Calling flushPendingOperations() causes any deferred operations to be executed immediately.

Gets the character format attributes that are common to all characters in the specified text range or current selection.

Format attributes that do not have the same value for all characters in the specified element range or selection are set to null in the returned TextLayoutFormat instance.

Parameters

 var common:ITextLayoutFormat = textFlow.interactionManager.getCommonCharacterFormat();

Gets the container format attributes that are common to all containers in the specified text range or current selection.

Format attributes that do not have the same value for all containers in the specified element range or selection are set to null in the returned TextLayoutFormat instance.

Parameters

 var common:ITextLayoutFormat = textFlow.interactionManager.getCommonContainerFormat();

Gets the paragraph format attributes that are common to all paragraphs in the specified text range or current selection.

Format attributes that do not have the same value for all paragraphs in the specified element range or selection are set to null in the returned TextLayoutFormat instance.

Parameters

 var common:ITextLayoutFormat = textFlow.interactionManager.getCommonParagraphFormat();

Gets the SelectionState object of the current selection.

Related API Elements

 var selection:SelectionState = textFlow.interactionManager.getSelectionState();

Indicates whether there is a selection.

Returns true if there is either a range selection or a point selection. By default, when a selection manager is first set up, there is no selection (the start and end are -1).

 var selection:SelectionState = textFlow.interactionManager.hasSelection();

Indicates whether the selection covers a range of text.

Returns true if there is a selection that extends past a single position.

 var selection:SelectionState = textFlow.interactionManager.isRangeSelection();

Updates the selection manager when text is inserted or deleted.

Operations must call notifyInsertOrDelete when changing the text in the text flow. The selection manager adjusts index-based position indicators accordingly. If you create a new Operation class that changes text in a text flow directly (not using another operation) your operation must call this function to keep the selection up to date.

Parameters

 import flashx.textLayout.elements.SpanElement;
 

function doReplace( span:SpanElement, newText:String, relativeStart:int, relativeEnd:int ):void
{
    span.replaceText(  relativeStart, relativeEnd, newText );
    var parentFlow:TextFlow = span.getTextFlow();
    var lengthDifference:int = newText.length - (relativeEnd - relativeStart);

    parentFlow.interactionManager.notifyInsertOrDelete(    span.getAbsoluteStart() + relativeStart, lengthDifference );
}

Redisplays the selection shapes.

Note: You do not need to call this method directly. It is called automatically.

Selects the entire flow.

Selects a range of text.

If a negative number is passed as either of the parameters, then any existing selection is removed.

Parameters

 var textFlow:TextFlow = TextConverter.importToFlow( "Let me not to the marriage of true minds", TextConverter.PLAIN_TEXT_FORMAT );
 textFlow.interactionManager = new SelectionManager();
 
 textFlow.interactionManager.selectRange( 18, 26 ); // Selects the word 'marriage'

Gives the focus to the first container in the selection.

 textFlow.interactionManager.setFocus();

Sets the SelectionState object of the current selection.
