Class Description


______________________________________________________________________________

 A diamond is defined by :
   - Its central left coordinates x1,y1
   - Its top central coordinates x2,y2

 A diamond has line attributes (see TAttLine)
   and fill area attributes (see TAttFill).

 Like for the class TPaveText, a TDiamond may have one or more line(s)
 of text inside.










 TDiamond()


 Diamond default constructor.



 TDiamond(Double_t x1, Double_t y1,Double_t x2, Double_t  y2)


 Diamond standard constructor.



 ~TDiamond()


 Diamond destructor.



 TDiamond(const TDiamond &diamond)


 Copy constructor.



Int_t DistancetoPrimitive(Int_t px, Int_t py)


 Compute distance from point px,py to a diamond.

  Compute the closest distance of approach from point px,py to the
  edges of this diamond.
  The distance is computed in pixels units.



void Draw(Option_t *option)


 Draw this diamond with its current attributes.



void ExecuteEvent(Int_t event, Int_t px, Int_t py)


 Execute action corresponding to one event.

  This member function is called when a Diamond object is clicked.

  If the mouse is clicked inside the diamond, the diamond is moved.

  If the mouse is clicked on the 4 tops (pL,pR,pTop,pBot), the diamond is rscaled.


                           pTop
                        +---------+
                        |   / \   |
                        |  /   \  |
                        | /     \ |
                      pL|/pinside\|pR
                        |\       /|
                        | \     / |
                        |  \   /  |
                        |   \ /   |
                        +---------+
                            pBot



void Paint(Option_t *)


 Paint this diamond with its current attributes.



void SavePrimitive(ostream &out, Option_t * /*= ""*/)


 Save primitive as a C++ statement(s) on output stream out.
