TGTextEdit
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.
TGTextEdit(const TGWindow *parent, UInt_t w, UInt_t h, TGText *text,
Int_t id, UInt_t sboptions, ULong_t back) :
TGTextView(parent, w, h, text, 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.
~TGTextEdit()
Cleanup text edit widget.
void Init()
Initiliaze a text edit widget.
void SetMenuState()
Enable/disable menu items in function of what is possible.
Long_t ReturnLongestLineWidth()
Return width of longest line in widget.
void Clear(Option_t *)
Clear text edit widget.
Bool_t SaveFile(const char *filename, Bool_t saveas)
Save file. If filename==0 ask user via dialog for a filename, if in
addition saveas==kTRUE always ask for new filename. Returns
kTRUE if file was correctly saved, kFALSE otherwise.
Bool_t Copy()
Copy text.
Bool_t Cut()
Cut text.
Bool_t Paste()
Paste text into widget.
void Print(Option_t *) const
Send current buffer to printer.
void Delete(Option_t *)
Delete selection.
Bool_t Search(const char *string, Bool_t direction,
Bool_t caseSensitive)
Search for string in the specified direction. If direction is true
the search will be in forward direction.
Bool_t Replace(TGLongPosition textPos, const char *oldText,
const char *newText, Bool_t direction, Bool_t caseSensitive)
Replace text starting at textPos.
Bool_t Goto(Long_t line, Long_t column)
Goto the specified line.
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.
Bool_t HandleCrossing(Event_t *event)
Handle mouse crossing event.
Bool_t HandleFocusChange(Event_t *event)
Handle focus change event in text edit widget.
Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t parm2)
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()
Break a line.
void ScrollCanvas(Int_t new_top, Int_t direction)
Scroll the canvas to new_top in the kVertical or kHorizontal direction.
void SetFocus()
Gives the keyboard input focus to this text edit widget.
void DrawRegion(Int_t x, Int_t y, UInt_t width, UInt_t height)
Redraw the text edit widget.
void PrevChar()
Go to the previous character.
void NextChar()
Go to next character.
void LineUp()
Make current position first line in window by scrolling up.
void LineDown()
Move one line down.
void ScreenUp()
Move one screen up.
void ScreenDown()
Move one screen down.
void Home()
Move to beginning of line.
void End()
Move to end of line.
