 A TGTextEdit is a specialization of TGTextView. It provides the      
 text edit functionality to the static text viewing widget.           
 For the messages supported by this widget see the TGView class.      
                                                                      


TGTextEdit(const TGWindow *parent, UInt_t w, UInt_t h, Int_t id, UInt_t sboptions, ULong_t back) : TGTextView(parent, w, h, id, sboptions, back)

 Create a text edit widget. Initialize it with the specified text buffer.

TGTextEdit(const TGWindow *parent, UInt_t w, UInt_t h, const char *string, Int_t id, UInt_t sboptions, ULong_t back) : TGTextView(parent, w, h, string, id, sboptions, back)
 Create a text edit widget. Initialize it with the specified string.

void SetInsertMode(EInsertMode mode)
 Sets the mode how characters are entered.

void CursorOff()
 If cursor if on, turn it off.

void CursorOn()
 Turn cursor on.

void SetCurrent(TGLongPosition new_coord)
 Make the specified position the current position.

void DrawCursor(Int_t mode)
 Draw cursor. If mode = 1 draw cursor, if mode = 2 erase cursor.

void AdjustPos()
 Adjust current position.

Bool_t HandleTimer(TTimer *t)
 Handle timer cursor blink timer.

Bool_t HandleSelection(Event_t *event)
 Handle selection notify event.

Bool_t HandleButton(Event_t *event)
 Handle mouse button event in text edit widget.

Bool_t HandleMotion(Event_t *event)
 Handle mouse motion event in text edit widget.

Bool_t HandleKey(Event_t *event)
 The key press event handler converts a key press to some line editor
 action.

 Process context menu messages.

void InsChar(char character)
 Insert a character in the text edit widget.

void DelChar()
 Delete a character from the text edit widget.

void BreakLine()
