/** \class TPaveText
\ingroup BasicGraphics

A Pave (see TPave) with text, lines or/and boxes inside.

Line (and boxes) are positioned in the pave using coordinates relative to
the pave (%).

The text lines are added in order using the AddText method. Also line separators
can be added, in order too, using the AddLine method.

AddText returns a TText corresponding to the line added to the pave. This
return value can be used to modify the text attributes.

Once the TPaveText is build the text of each line can be retrieved using
GetLine or GetLineWith as a TText wich is useful to modify the text attributes
of a line.

Example:
Begin_Macro(source)
../../../tutorials/graphics/pavetext.C
End_Macro

GetListOfLines can also be used to retrieve all the lines in the TPaveText as
a TList:

Begin_Macro(source)
{
   TPaveText *t = new TPaveText(.05,.3,.95,.6);
   t->AddText("This line is blue"); ((TText*)t->GetListOfLines()->Last())->SetTextColor(kBlue);
   t->AddText("This line is red");  ((TText*)t->GetListOfLines()->Last())->SetTextColor(kRed);
   t->Draw();
}
End_Macro
