\class QMargins
\inmodule QtCore
\ingroup painting
\since 4.6
\brief The QMargins class defines the four margins of a rectangle.
QMargin defines a set of four margins; left, top, right and bottom,
that describe the size of the borders surrounding a rectangle.
The isNull() function returns true only if all margins are set to zero.
QMargin objects can be streamed as well as compared.
