Constructor & Destructor Documentation

◆ TVirtualHistPainter()

TVirtualHistPainter::TVirtualHistPainter ( )

Definition at line 36 of file TVirtualHistPainter.h.

Member Function Documentation

◆ DistancetoPrimitive()

virtual Int_t TVirtualHistPainter::DistancetoPrimitive ( Int_t  px,
Int_t  py 
)
pure virtual

Computes distance from point (px,py) to the object.

This member function must be implemented for each graphics primitive. This default function returns a big number (999999).

Reimplemented from TObject.

Implemented in THistPainter, and TGLHistPainter.

◆ DrawPanel()

virtual void TVirtualHistPainter::DrawPanel ( )
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ ExecuteEvent()

virtual void TVirtualHistPainter::ExecuteEvent ( Int_t  event,
Int_t  px,
Int_t  py 
)
pure virtual

Execute action corresponding to an event at (px,py).

This method must be overridden if an object can react to graphics events.

Reimplemented from TObject.

Implemented in THistPainter, and TGLHistPainter.

◆ GetContourList()

virtual TList* TVirtualHistPainter::GetContourList ( Double_t  contour) const
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ GetObjectInfo()

virtual char* TVirtualHistPainter::GetObjectInfo ( Int_t  px,
Int_t  py 
) const
pure virtual

Returns string containing info about the object at position (px,py).

This method is typically overridden by classes of which the objects can report peculiarities for different positions. Returned string will be re-used (lock in MT environment).

Reimplemented from TObject.

Implemented in THistPainter, and TGLHistPainter.

◆ GetStack()

virtual TList* TVirtualHistPainter::GetStack ( ) const
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ HistPainter()

TVirtualHistPainter * TVirtualHistPainter::HistPainter ( TH1 obj)
static

Static function returning a pointer to the current histogram painter.

The painter will paint the specified obj. If the histogram painter does not exist a default painter is created.

Definition at line 32 of file TVirtualHistPainter.cxx.

◆ IsInside() [1/2]

virtual Bool_t TVirtualHistPainter::IsInside ( Int_t  x,
Int_t  y 
)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ IsInside() [2/2]

virtual Bool_t TVirtualHistPainter::IsInside ( Double_t  x,
Double_t  y 
)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ MakeCuts()

virtual Int_t TVirtualHistPainter::MakeCuts ( char *  cutsopt)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ Paint()

virtual void TVirtualHistPainter::Paint ( Option_t option = "")
pure virtual

This method must be overridden if a class wants to paint itself.

The difference between Paint() and Draw() is that when a object draws itself it is added to the display list of the pad in which it is drawn (and automatically redrawn whenever the pad is redrawn). While paint just draws the object without adding it to the pad display list.

Reimplemented from TObject.

Implemented in THistPainter, and TGLHistPainter.

◆ PaintStat()

virtual void TVirtualHistPainter::PaintStat ( Int_t  dostat,
TF1 fit 
)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ ProcessMessage()

virtual void TVirtualHistPainter::ProcessMessage ( const char *  mess,
const TObject obj 
)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ SetHighlight()

virtual void TVirtualHistPainter::SetHighlight ( )
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ SetHistogram()

virtual void TVirtualHistPainter::SetHistogram ( TH1 h)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ SetPainter()

void TVirtualHistPainter::SetPainter ( const char *  painter)
static

Static function to set an alternative histogram painter.

Definition at line 57 of file TVirtualHistPainter.cxx.

◆ SetShowProjection()

virtual void TVirtualHistPainter::SetShowProjection ( const char *  option,
Int_t  nbins 
)
pure virtual

Implemented in THistPainter, and TGLHistPainter.

◆ SetStack()

virtual void TVirtualHistPainter::SetStack ( TList stack)
pure virtual

Implemented in THistPainter, and TGLHistPainter.
