Class Description


   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.

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.

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 CBoxX[4], Int_t CBoxY[4])
 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)
 Return text size in pixels
void GetTextAscentDescent(UInt_t &a, UInt_t &d, const char *text)
 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)
 Return text extent for string text
  in w return total text width
  in h return text height

*-*                  ===========================================
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 SavePrimitive(ostream &out, Option_t * /*= ""*/)
 Save primitive as a C++ statement(s) on output stream out
void SetNDC(Bool_t isNDC)
 Set NDC mode on if isNDC = kTRUE, off otherwise
void Streamer(TBuffer &R__b)
 Stream an object of class TText.
Double_t GetX()
{ return fX; }
Double_t GetY()
{ return fY; }
void SetText(Double_t x, Double_t y, const char *text)
