TPaveText : to draw a pave with text

A PaveText is a Pave (see TPave) with text, lines or/and boxes inside. Line (and boxes) are positionned in the pave using coordinates relative to the pave (%).

 TPaveText()


 pavetext default constructor.





 TPaveText(Double_t x1, Double_t y1, Double_t x2, Double_t y2, Option_t* option = "br")


 PaveText normal constructor.

 A PaveText is a Pave with several lines of text

  option = "TR" Top and Right shadows are drawn.
  option = "TL" Top and Left shadows are drawn.
  option = "BR" Bottom and Right shadows are drawn.
  option = "BL" Bottom and Left shadows are drawn.

  If none of these four above options is specified the default the
  option "BR" will be used to draw the border. To produces a pave
  without any border it is enough to specify the option "NB" (no border).

  option = "NDC" x1,y1,x2,y2 are given in NDC
  option = "ARC" corners are rounded

 In case of option "ARC", the corner radius is specified
 via TPave::SetCornerRadius(rad) where rad is given in percent
 of the pave height (default value is 0.2).

 The individual text items are entered via AddText
 By default, text items inherits from the default pavetext AttText.
 A title can be added later to this pavetext via TPaveText::SetLabel.
