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 TGLHistPainter, and THistPainter.
Referenced by TH1::DistancetoPrimitive().

Implemented in TGLHistPainter, and THistPainter.
Referenced by TH1::DrawPanel().
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 TGLHistPainter, and THistPainter.
Referenced by TH1::ExecuteEvent().
Implemented in TGLHistPainter, and THistPainter.
Referenced by TGraph2D::GetContourList().
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).

Implemented in TGLHistPainter, and THistPainter.

Implemented in TGLHistPainter, and THistPainter.
Referenced by TH2::DoProfile(), and TH2::DoProjection().
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.
