Text documents are represented by the
QTextDocument class, rather than by QString objects.
Each QTextDocument object contains information about
the document's internal representation, its structure,

layout management to be delegated to specialized
classes, but also provides a focus for the framework.""",

There are two complementary ways to visualize the
contents of a document: as a linear buffer that is
used by editors to modify the contents, and as an
object hierarchy containing structural information
that is useful to layout engines. In the hierarchical
model, the objects generally correspond to visual
elements such as frames, tables, and lists. At a lower
level, these elements describe properties such as the
style of text used and its alignment. The linear
representation of the document is used for editing and
manipulation of the document's contents.""",
