Méthodes publiques

Méthode	Description
ApplyWS ( int hvoWs ) : void	Applies the specified writing system to the current selection
GetAvailWidth ( IVwRootBox prootb ) : int	Simulate infinite width if needed.
InnerFwTextBox ( ) : System	Default constructor
MakeRoot ( ) : void	Create the root box and initialize it. We want this one to work even in design mode, and since we supply the cache and data ourselves, that's possible.
PropChanged ( int hvo, int tag, int ivMin, int cvIns, int cvDel ) : void	Any change to this private data access must be a change to our string, so check its length.
Select ( int start, int length ) : void	Selects a range of text in the text box. If you want to set the start position to the first character in the control's text, set the start parameter to 0. You can use this method to select a substring of text, such as when searching through the text of the control and replacing information. Note: You can programmatically move the caret within the text box by setting the start parameter to the position within the text box where you want the caret to move to and set the length parameter to a value of zero (0). The text box must have focus in order for the caret to be moved.

Méthodes protégées

Méthode	Description
CreateEditingHelper ( ) : EditingHelper	Creates a special extended editing helper for this text box.
Dispose ( bool disposing ) : void	Clean up any resources being used.
ExtToIntIndex ( int extIndex ) : int	Converts the external string index to the internal string index. They might be different because a line break character is used internally to represent a new line and CRLF is used externally on Windows to represent a new line.
IntToExtIndex ( int intIndex ) : int	Converts the internal string index to the external string index. They might be different because a line break character is used internally to represent a new line and CRLF is used externally on Windows to represent a new line.
MakeSelectionVisible ( IVwSelection sel, bool fWantOneLineSpace ) : bool	First try to make everything visible, if possible. This is especially helpful with RTL text.
OnKeyDown ( KeyEventArgs e ) : void	watch for keys to do the cut/copy/paste operations
OnKeyPress ( KeyPressEventArgs e ) : void	Override to suppress Enter key if it is not allowed.
OnMouseMoveSetCursor ( Point mousePos ) : void	show default cursor for read-only text boxes.
OnSizeChanged ( EventArgs e ) : void	When the edit box gets resized, recalc the maximum line height (when setting a Tss string, applying styles, or setting the WS, we need to reduce the font size if necessary to keep the text from being clipped by the height of the box).

Private Methods

Méthode	Description
AdjustHeight ( ) : bool	Adjusts text height after a style change.
BaseMakeSelectionVisible ( IVwSelection sel ) : void
CreateTempWritingSystemFactory ( ) : void	Make a writing system factory that is based on the Languages folder (ICU-based). This is only used in Designer, tests, and momentarily (during construction) in production, until the client sets supplies a real one.
RemoveNonRootNotifications ( ) : void
ReplaceAll ( ITsString tss, string oldSubStr, string newSubStr ) : ITsString
RestoreNonRootNotifications ( ) : void
ShutDownTempWsFactory ( ) : void	Shut down the writing system factory and release it explicitly.
SubstringCount ( string str, string substr ) : int
