C# Class SIL.FieldWorks.Common.RootSites.TextSelInfo

TextSelInfo is another variety of selection helper. It provides easy access to certain kinds of information in a selection. NOTE: some clients (e.g. EditingHelper.TextSelInfoBeforeEdit) depend upon the information cached in this object even after the underlying Selection has changed state.

Méthodes publiques

Méthode	Description
ContainingObject ( int level ) : int	ContainingObject info about anchor.
ContainingObject ( int level, bool fEndPoint ) : int	Level 0 returns the same object as Hvo(fEndPoint). Level 1 returns the object which contains the display of ContainingObject(0, fEndPoint). Level n returns the object which contains the display of ContainingObject(n-1, fEndPoint). Returns 0 if there was no selection or level is too large.
ContainingObjectIndex ( int level ) : int	ContainingObjectIndex info about anchor.
ContainingObjectIndex ( int level, bool fEndPoint ) : int	Level 0 returns zero. Level 1 returns the index of ContainingObject(0, fEndPoint) in property ContainingObjectTag(1, fEndPoint) of object ContainingObject(1, fEndPoint). Level n returns the index of ContainingObject(n-1, fEndPoint) in property ContainingObjectTag(n, fEndPoint) of object ContainingObject(n, fEndPoint). Returns 0 if there was no selection or level is too large (or the relevant property is atomic).
ContainingObjectTag ( int level ) : int	ContainingObjectTag info about anchor.
ContainingObjectTag ( int level, bool fEndPoint ) : int	Level 0 returns the same as Tag(fEndPoint). Level 1 returns the id of the property of ContainingObject(1, fEndPoint) which contains ContainingObject(0, fEndPoint). Level 1 returns the id of the property of ContainingObject(n, fEndPoint) which contains ContainingObject(n-1, fEndPoint). Returns 0 if there was no selection or level is too large.
Hvo ( bool fEndPoint ) : int	The id of the object that has the text property (Tag(fEndPoint) in which the selection occurs. Zero if no selection.
Levels ( bool fEndPoint ) : int	The number of layers of containing objects in the selection (Levels - 1 is the largest meaningful argument to pass to any of the containing object methods).
SelectedProperty ( bool fEndPoint ) : ITsString	The string in which the selection occurs...if there's a difference, passing true gets the end-point string, false the anchor string. Both null if no selection.
Tag ( bool fEndPoint ) : int	The id of the string property in which the selection occurs. Pass true for the property in which the end point occurs, false for anchor. Zero if no selection.
TextSelInfo ( IVwRootBox rootbox ) : System	Construct a TextSelInfo from the current selection of the root box.
TextSelInfo ( IVwSelection sel ) : System	Initializes a new instance of the T:TextSelInfo class.
WsAlt ( bool fEndPoint ) : int	The writing system alternative of the selection. Note that this is not necessarily the writing system of the selected text, or even the character adjacent to the selected end point; it identifies an alternative in a multilingual alternative property, and is zero if there is no selection or if the selected property is not multilingual.

Private Methods

Méthode	Description
