Detailed Description

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.
