The QgsMargins class defines the four margins of a rectangle.
QgsMargins()=default
Constructs a margins object with all margins set to 0.
void setBottom(double bottom)
Sets the bottom margin to bottom.
QgsMargins & operator*=(double factor)
Multiplies each component of this object by factor and returns a reference to it.
double top() const
Returns the top margin.
void setLeft(double left)
Sets the left margin to left.
bool isNull() const
Returns true if all margins are is 0; otherwise returns false.
double right() const
Returns the right margin.
double bottom() const
Returns the bottom margin.
QgsMargins & operator/=(double divisor)
Multiplies each component of this object by factor and returns a reference to it.
