Constructor & Destructor Documentation

◆ QgsBasicNumericFormat()

QgsBasicNumericFormat::QgsBasicNumericFormat ( )

Default constructor.

Definition at line 40 of file qgsbasicnumericformat.cpp.

Member Function Documentation

◆ clone()

QgsNumericFormat * QgsBasicNumericFormat::clone ( ) const
overridevirtual

Clones the format, returning a new object.

The caller takes ownership of the returned object.

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsPercentageNumericFormat, QgsCurrencyNumericFormat, and QgsScientificNumericFormat.

Definition at line 131 of file qgsbasicnumericformat.cpp.

◆ configuration()

QVariantMap QgsBasicNumericFormat::configuration ( const QgsReadWriteContext context) const
overridevirtual

Returns the current configuration of the formatter.

This value can be used in a call to create() in order to recreate this formatter in its current state.

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsPercentageNumericFormat, QgsCurrencyNumericFormat, and QgsScientificNumericFormat.

Definition at line 143 of file qgsbasicnumericformat.cpp.

◆ create()

QgsNumericFormat * QgsBasicNumericFormat::create ( const QVariantMap &  configuration,
const QgsReadWriteContext context 
) const
overridevirtual

Creates a new copy of the format, using the supplied configuration.

The caller takes ownership of the returned object.

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsPercentageNumericFormat, QgsCurrencyNumericFormat, and QgsScientificNumericFormat.

Definition at line 136 of file qgsbasicnumericformat.cpp.

◆ decimalSeparator()

QChar QgsBasicNumericFormat::decimalSeparator ( ) const

Returns any override for the decimal separator character.

If an invalid QChar is returned, then the QGIS locale separator is used instead.

See also
setDecimalSeparator()

Definition at line 227 of file qgsbasicnumericformat.cpp.

◆ formatDouble()

QString QgsBasicNumericFormat::formatDouble ( double  value,
const QgsNumericFormatContext context 
) const
overridevirtual

Returns a formatted string representation of a numeric double value.

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsPercentageNumericFormat, QgsCurrencyNumericFormat, and QgsScientificNumericFormat.

Definition at line 59 of file qgsbasicnumericformat.cpp.

◆ id()

QString QgsBasicNumericFormat::id ( ) const
overridevirtual

Returns a unique id for this numeric format.

This id is used to identify this numeric format in the registry with QgsNumericFormatRegistry::format().

Implements QgsNumericFormat.

Reimplemented in QgsBearingNumericFormat, QgsPercentageNumericFormat, QgsCurrencyNumericFormat, and QgsScientificNumericFormat.

Definition at line 44 of file qgsbasicnumericformat.cpp.

◆ numberDecimalPlaces()

int QgsBasicNumericFormat::numberDecimalPlaces ( ) const

Returns the maximum number of decimal places to show.

◆ roundingType()

QgsBasicNumericFormat::RoundingType QgsBasicNumericFormat::roundingType ( ) const

Returns the rounding type, which controls the behavior of the numberDecimalPlaces() setting.

See also
setRoundingType()

Definition at line 207 of file qgsbasicnumericformat.cpp.

◆ setConfiguration()

void QgsBasicNumericFormat::setConfiguration ( const QVariantMap &  configuration,
const QgsReadWriteContext context 
)
