Detailed Description
The QMarginsF class defines the four margins of a rectangle.
QMarginsF 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.
QMarginsF objects can be streamed as well as compared.
