Class Description

______________________________________________________________________________

 Manages Markers. Marker attributes are managed by TAttMarker.
 The list of standard ROOT markers is shown in this picture

TMarker()

 Marker default constructor.

TMarker(Double_t x, Double_t y, Int_t marker)

 Marker normal constructor.

~TMarker()

 Marker default destructor.

TMarker(const TMarker &marker)

 Marker copy constructor.

void Copy(TObject &obj)

 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 *)

 List this marker with its attributes.

void Paint(Option_t *)

 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, Double_t)

 Draw this marker with new coordinates in NDC.

void Print(Option_t *)

 Dump this marker with its attributes.

void SavePrimitive(ostream &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 TMarker.

Double_t GetX()

Double_t GetY()

void SetX(Double_t x)

void SetY(Double_t y)
