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.

TText(const TText &text) : TNamed(text), TAttText(text)

void Copy(TObject &obj) const
*-*-*-*-*-*-*-*-*-*-*Copy this text to text*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ======================

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* DrawTextNDC(Double_t x, Double_t y, const char *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 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 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 ls(Option_t *) const
*-*-*-*-*-*-*-*-*-*-*-*List this text with its attributes*-*-*-*-*-*-*-*-*
*-*                    ==================================

void Paint(Option_t *)
*-*-*-*-*-*-*-*-*-*-*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 PaintTextNDC(Double_t u, Double_t v, const char *text)
*-*-*-*-*-*-*-*-*-*-*Draw this text with new coordinates in NDC*-*-*-*-*-*-*
*-*                  ==========================================

void Print(Option_t *) const
*-*-*-*-*-*-*-*-*-*-*Dump this text with its attributes*-*-*-*-*-*-*-*-*-*
*-*                  ==================================

void SavePrimitive(ofstream &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.
