Detailed Description#

QMarginsF defines a set of four margins; left, top, right, and bottom, that describe the finite size of the borders surrounding a rectangle.

The isNull() function returns true only if all margins are very close to zero.

QMarginsF objects can be streamed as well as compared.

__init__(margins)#
Parameters:

marginsQMargins

Constructs margins copied from the given margins.

See also

toMarginsF()

__init__(left, top, right, bottom)
Parameters:
  • left – float

  • top – float

  • right – float

  • bottom – float

Constructs margins with the given left, top, right, and bottom. All parameters must be finite.

__init__()

Constructs a margins object with all margins set to 0.

isNull()

bottom()#
Return type:

float

Returns the bottom margin.

See also

setBottom()

isNull()#
Return type:

bool

Returns true if all margins are very close to 0; otherwise returns false.

See also

qFuzzyIsNull()

left()#
Return type:

float

Returns the left margin.

setLeft()

__ne__(rhs)#
Parameters:

rhsQMarginsF

Return type:

bool

Returns true if lhs and rhs are sufficiently different; otherwise returns false.

Warning

This function does not check for strict inequality; instead, it uses a fuzzy comparison to compare the margins.

qFuzzyCompare

__mul__(lhs)#
Parameters:

lhs – float

Return type:

QMarginsF

This is an overloaded function.

Returns a QMarginsF object that is formed by multiplying each component of the given lhs margins by finite factor rhs.

__mul__(rhs)
Parameters:

rhs – float

Return type:

QMarginsF

This is an overloaded function.

Returns a QMarginsF object that is formed by multiplying each component of the given lhs margins by finite factor rhs.

operator*=() operator/=()

__imul__(factor)#
Parameters:

factor – float

Return type:

QMarginsF

Multiplies each component of this object by the given finite factor and returns a reference to this object.

operator/=()

__add__()#
Return type:

QMarginsF

Returns a QMargin object that is formed from all components of margins.

__add__(rhs)
Parameters:

rhsQMarginsF

Return type:

QMarginsF

Returns a QMarginsF object that is the sum of the given margins, lhs and rhs; each component is added separately.

__add__(lhs)
Parameters:

lhs – float

Return type:

QMarginsF

Returns a QMarginsF object that is formed by adding lhs (which must be finite) to each component of rhs.

See also

operator+=() operator-=()

__add__(rhs)
Parameters:

rhs – float

Return type:

QMarginsF

Returns a QMarginsF object that is formed by adding rhs (which must be finite) to each component of lhs.

operator+=() operator-=()

__iadd__(margins)#
Parameters:

marginsQMarginsF

Return type:

QMarginsF

Add each component of margins to the respective component of this object and returns a reference to it.

operator-=()

__iadd__(addend)
Parameters:

addend – float

Return type:

QMarginsF

This is an overloaded function.

Adds the given finite addend to each component of this object and returns a reference to it.

operator-=()

__sub__()#
Return type:

QMarginsF

Returns a QMargin object that is formed by negating all components of margins.

__sub__(rhs)
Parameters:

rhs – float

Return type:

QMarginsF

Returns a QMarginsF object that is formed by subtracting rhs (which must be finite) from each component of lhs.

See also

__sub__(rhs)
Parameters:

rhsQMarginsF

Return type:

QMarginsF

Returns a QMarginsF object that is formed by subtracting rhs from lhs; each component is subtracted separately.

__isub__(margins)#
Parameters:

marginsQMarginsF

Return type:

QMarginsF

Subtract each component of margins from the respective component of this object and returns a reference to it.

operator+=()

__isub__(subtrahend)
Parameters:

subtrahend – float

Return type:

QMarginsF

This is an overloaded function.

Subtracts the given finite subtrahend from each component of this object and returns a reference to it.

__div__(divisor)#
Parameters:

divisor – float

Return type:

QMarginsF

This is an overloaded function.

Returns a QMarginsF object that is formed by dividing the components of the given lhs margins by the given rhs divisor.

The divisor must not be either zero or NaN.

See also

operator*=() operator/=()

operator/=(divisor)
Parameters:

divisor – float

Return type:

QMarginsF

__eq__(rhs)#
Parameters:

rhsQMarginsF

Return type:

bool

Returns true if lhs and rhs are approximately equal; otherwise returns false.
