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 spped 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*-*-*-*-*
*-*                  =============================================
  Compute the closest distance of approach from point px,py to this text.
  The rectangle surrounding this string is evaluated.
  if point is in 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
