class TBox: public TObject, public TAttLine, public TAttFill

 Box default constructor.

 Box standard constructor.

 Box destructor.

 Box copy constructor.

 Assignment operator.

 Copy a Box.

 Compute distance from point px,py to a box.

 Compute the closest distance of approach from point px,py to the
 edges of this box.
 The distance is computed in pixels units.

 Draw this box with its current attributes.
 if the box has no fill style (ie fill style=0), the box contour is drawn
 if the box has a fill style, the box contour is not drawn by default.
 to force the contour to be drawn, specify option "l"

 Draw this box with new coordinates.

 Execute action corresponding to one event.

  This member function is called when a BOX/WBOX/PAD object is clicked.

  If the mouse is clicked in one of the 4 corners of the box (pA,pB,pC,pD)
  the box is resized with the rubber rectangle.

  If the mouse is clicked inside the box, the box is moved.

  If the mouse is clicked on the 4 edges (pL,pR,pTop,pBot), the box is
  rescaled parallel to this edge (same as Motif window manager).
