Class Description

  a PolyMarker is defined by an array on N points in a 2-D space.
 At each point x[i], y[i] a marker is drawn.
 Marker attributes are managed by TAttMarker.
 See TMarker for the list of possible marker types.

*-*-*-*-*-*-*-*-*Compute distance from point px,py to a polymarker*-*-*-*-*-*
*-*              ===============================================
  Compute the closest distance of approach from point px,py to each point
  of the polymarker.
  Returns when the distance found is below DistanceMaximum.
  The distance is computed in pixels units.

*-*-*-*-*-*-*-*-*-*-*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

 Merge polymarkers in the collection in this polymarker

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

 Set point following LastPoint to x, y.
 Returns index of the point (new last point).

 set point number n
 if n is greater than the current size, the arrays are automatically
 extended

 if n <= 0 the current arrays of points are deleted.

 if n <= 0 the current arrays of points are deleted.

 if n <= 0 the current arrays of points are deleted.

*-*-*-*-*-*-*-*-*Stream a class object*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*              =========================================
