class TText: public TNamed, public TAttText, public TAttBBox2D


   TText is the base class for several text objects.
   See TAttText for a list of text attributes or fonts,
   and also for a discussion on text speed and font quality.

  By default, the text is drawn in the pad coordinates system.
  One can draw in NDC coordinates [0,1] if the function SetNDC
  is called for a TText object.

Function documentation

TText()
 Text default constructor.
TText(Double_t x, Double_t y, const char* text)
 Text normal constructor.
TText(Double_t x, Double_t y, const wchar_t* text)
 Text normal constructor.
~TText()
 Text default destructor.
TText(const TText& text)
 Copy constructor.
void Copy(TObject& text) const
 Copy this text to text.
const void * GetWcsTitle(void)
 Returns the text as UNICODE.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to a string.
 The rectangle surrounding this string is evaluated.
 If the point (px,py) is in the rectangle, the distance is set to zero.
TText * DrawText(Double_t x, Double_t y, const char* text)
 Draw this text with new coordinates.
TText * DrawText(Double_t x, Double_t y, const wchar_t* text)
 Draw this text with new coordinates.
TText * DrawTextNDC(Double_t x, Double_t y, const char* text)
 Draw this text with new coordinates in NDC.
TText * DrawTextNDC(Double_t x, Double_t y, const wchar_t* text)
 Draw this text with new coordinates in NDC.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.

  This member function must be implemented to realize the action
  corresponding to the mouse click on the object in the window
void GetControlBox(Int_t x, Int_t y, Double_t theta, Int_t[4] cBoxX, Int_t[4] cBoxY)
 Return the text control box. The text position coordinates is (x,y) and
 the text angle is theta. The control box coordinates are returned in cBoxX
 and cBoxY.
void GetBoundingBox(UInt_t& w, UInt_t& h, Bool_t angle = kFALSE)
 Return text size in pixels. By default the size returned does not take
 into account the text angle (angle = kFALSE). If angle is set to kTRUE
 w and h take the angle into account.
void GetTextAscentDescent(UInt_t& a, UInt_t& d, const char* text) const
 Return text ascent and descent for string text
  in a return total text ascent
  in d return text descent
void GetTextAscentDescent(UInt_t& a, UInt_t& d, const wchar_t* text) const
 Return text ascent and descent for string text
  in a return total text ascent
  in d return text descent
void GetTextExtent(UInt_t& w, UInt_t& h, const char* text) const
 Return text extent for string text
  in w return total text width
  in h return text height
void GetTextAdvance(UInt_t& a, const char* text, const Bool_t kern = kTRUE) const
 Return text advance for string text
 if kern is true (default) kerning is taken into account. If it is false
 the kerning is not taken into account.
void GetTextExtent(UInt_t& w, UInt_t& h, const wchar_t* text) const
 Return text extent for string text
  in w return total text width
  in h return text height
void ls(Option_t* option = "") const
 List this text with its attributes.

 Paint this text with its current attributes.
void PaintControlBox(Int_t x, Int_t y, Double_t theta)
 Paint the text control box. (x,y) are the coordinates where the control
 box should be painted and theta is the angle of the box.
void PaintText(Double_t x, Double_t y, const char* text)
 Draw this text with new coordinates.
void PaintText(Double_t x, Double_t y, const wchar_t* text)
 Draw this text with new coordinates.

 Draw this text with new coordinates in NDC.
void PaintTextNDC(Double_t u, Double_t v, const wchar_t* text)
 Draw this text with new coordinates in NDC.
void Print(Option_t* option = "") const
 Dump this text with its attributes.
void SavePrimitive(ostream& out, Option_t* option = "")
 Save primitive as a C++ statement(s) on output stream out
