Function documentation

TMarker(const TMarker& marker)
 Marker default constructor.
TMarker(Double_t x, Double_t y, Int_t marker)
 Marker normal constructor.
 Marker default destructor.
TMarker(const TMarker& marker)
 Marker copy constructor.
void Copy(TObject& marker) const
 Copy this marker to marker.
void DisplayMarkerTypes()
 Display the table of markers with their numbers.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to a marker.

  Compute the closest distance of approach from point px,py to this marker.
  The distance is computed in pixels units.
void Draw(Option_t* option = "")
 Draw this marker with its current attributes.
void DrawMarker(Double_t x, Double_t y)
 Draw this marker with new coordinates.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.

  This member function is called when a marker is clicked with the locator

  If Left button is clicked on a marker, the marker is moved to
  a new position when the mouse button is released.
void ls(Option_t* option = "") const
 List this marker with its attributes.
void Paint(Option_t* option = "")
 Paint this marker with its current attributes.
void PaintMarker(Double_t x, Double_t y)
 Draw this marker with new coordinates.
void PaintMarkerNDC(Double_t u, Double_t v)
 Draw this marker with new coordinates in NDC.
void Print(Option_t* option = "") const
 Dump this marker with its attributes.
void SavePrimitive(ostream& out, Option_t* option = "")
 Save primitive as a C++ statement(s) on output stream out
void SetNDC(Bool_t isNDC = kTRUE)
 Set NDC mode on if isNDC = kTRUE, off otherwise
void Streamer(TBuffer& b)
 Stream an object of class TMarker.
Double_t GetX()
{return fX;}
Double_t GetY()
{return fY;}
void SetX(Double_t x)
{ fX = x;}
void SetY(Double_t y)
{ fY = y;}
