53 | \brief The QMargins class defines the four margins of a rectangle.
|
---|
54 |
|
---|
55 | QMargin defines a set of four margins; left, top, right and bottom,
|
---|
56 | that describe the size of the borders surrounding a rectangle.
|
---|
57 |
|
---|
58 | The isNull() function returns true only if all margins are set to zero.
|
---|
59 |
|
---|
60 | QMargin objects can be streamed as well as compared.
