Public Methods

Method	Description
AddHyperlink ( ITsStrBldr strBldr, int ws, string sLinkText, string sUrl, FwStyleSheet stylesheet ) : bool	Appends the given text as a hyperlink to the given URL.
FwEditingHelper ( SIL.FieldWorks.FDO.FdoCache cache, IEditingCallbacks callbacks ) : System	Initializes a new instance of the FwEditingHelper class.
HandleSelectionChange ( IVwRootBox prootb, IVwSelection vwselNew ) : void	Change the system keyboard when the selection changes. When overriding you should call the base class first.
InsertPicture ( ICmPicture pict ) : void	Inserts an ORC pointing to hvoObjToInsert at the current selection location. Enhance JohnT: should move this to RootSite or similar location where all clients can readily use it.
InsertPicture ( string srcFilename, ITsString captionTss, string sFolder ) : void	Insert a picture at the current selection of the active rootsite.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Executes in two distinct scenarios. 1. If disposing is true, the method has been called directly or indirectly by a user's code via the Dispose method. Both managed and unmanaged resources can be disposed. 2. If disposing is false, the method has been called by the runtime from inside the finalizer and you should not reference (access) other managed objects, as they already have been garbage collected. Only unmanaged resources can be disposed. If any exceptions are thrown, that is fine. If the method is being done in a finalizer, it will be ignored. If it is thrown by client code calling Dispose, it needs to be handled by fixing the bug. If subclasses override this method, they should call the base implementation.
InsertPictureOrc ( ICmPicture pict, ITsString tss, int ich, int hvoObj, int propTag, int ws ) : void	This method is broken out so TeEditingHelper can override and adjust annotations. Probably anything else that does it will need to adjust annotations, too, but nothing else yet uses this kind of picture in an StText.
OnCharAux ( string stuInput, VwShiftStatus ss, Keys modifiers ) : void	Handle typed character
ValidToReplaceSelWithTss ( IVwSelection vwselTargetLocation, ITsString tss ) : bool	Determines whether the given TsString can be pasted in the context of the target selection. An old DN-style embedded picture can only be pasted into paragraph contents.

Method Details

AddHyperlink() public static method

Appends the given text as a hyperlink to the given URL.

public static AddHyperlink ( ITsStrBldr strBldr, int ws, string sLinkText, string sUrl, FwStyleSheet stylesheet ) : bool
strBldr	ITsStrBldr	The string builder.
ws	int	The HVO of the writing system to use for the added text.
sLinkText	string	The text which should appear as the hyperlink text
sUrl	string	The URL that is the target of the hyperlink.
stylesheet	FwStyleSheet	The stylesheet.
return	bool

Dispose() protected method

Executes in two distinct scenarios. 1. If disposing is true, the method has been called directly or indirectly by a user's code via the Dispose method. Both managed and unmanaged resources can be disposed. 2. If disposing is false, the method has been called by the runtime from inside the finalizer and you should not reference (access) other managed objects, as they already have been garbage collected. Only unmanaged resources can be disposed.

If any exceptions are thrown, that is fine. If the method is being done in a finalizer, it will be ignored. If it is thrown by client code calling Dispose, it needs to be handled by fixing the bug. If subclasses override this method, they should call the base implementation.

protected Dispose ( bool disposing ) : void
disposing	bool
return	void

FwEditingHelper() public method

Initializes a new instance of the FwEditingHelper class.

public FwEditingHelper ( SIL.FieldWorks.FDO.FdoCache cache, IEditingCallbacks callbacks ) : System
cache	SIL.FieldWorks.FDO.FdoCache	The DB connection
callbacks	IEditingCallbacks	implementation of
return	System

HandleSelectionChange() public method

Change the system keyboard when the selection changes.

When overriding you should call the base class first.

public HandleSelectionChange ( IVwRootBox prootb, IVwSelection vwselNew ) : void
prootb	IVwRootBox
vwselNew	IVwSelection	Selection
return	void

InsertPicture() public method

Inserts an ORC pointing to hvoObjToInsert at the current selection location. Enhance JohnT: should move this to RootSite or similar location where all clients can readily use it.

public InsertPicture ( ICmPicture pict ) : void
pict	ICmPicture	The picture to insert
return	void

InsertPicture() public method

Insert a picture at the current selection of the active rootsite.

public InsertPicture ( string srcFilename, ITsString captionTss, string sFolder ) : void
srcFilename	string	The path to the original filename (an internal copy will /// be made in this method)
captionTss	ITsString	The caption
sFolder	string	The name of the CmFolder where picture should be stored
return	void

InsertPictureOrc() protected method

This method is broken out so TeEditingHelper can override and adjust annotations. Probably anything else that does it will need to adjust annotations, too, but nothing else yet uses this kind of picture in an StText.

pict	ICmPicture	The picture to insert an ORC for
tss	ITsString	The initial value of the TsString into which the ORC is to be /// inserted.
ich	int	The character offset into the string.
hvoObj	int	The hvo of the object that owns the string property that will /// receive the tss after the ORC is inserted (typically a paragraph).
propTag	int	The property that holds the string.
ws	int	The writing system ID if the property is a multi-string.
return	void
