Since: QGIS 3.12

Definition at line 28 of file qgsscientificnumericformat.h.

Constructor & Destructor Documentation

◆ QgsScientificNumericFormat()

QgsScientificNumericFormat::QgsScientificNumericFormat ( )

Default constructor.

Definition at line 21 of file qgsscientificnumericformat.cpp.

Member Function Documentation

◆ clone()

QgsNumericFormat * QgsScientificNumericFormat::clone ( ) const

overridevirtual

Clones the format, returning a new object.

The caller takes ownership of the returned object.

Reimplemented from QgsBasicNumericFormat.

Definition at line 46 of file qgsscientificnumericformat.cpp.

◆ configuration()

QVariantMap QgsScientificNumericFormat::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.

Reimplemented from QgsBasicNumericFormat.

Definition at line 59 of file qgsscientificnumericformat.cpp.

◆ create()

QgsNumericFormat * QgsScientificNumericFormat::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.

Reimplemented from QgsBasicNumericFormat.

Definition at line 51 of file qgsscientificnumericformat.cpp.

◆ formatDouble()

QString QgsScientificNumericFormat::formatDouble	(	double	value,
		const QgsNumericFormatContext &	context
	)		const

overridevirtual

Returns a formatted string representation of a numeric double value.

Reimplemented from QgsBasicNumericFormat.

Definition at line 41 of file qgsscientificnumericformat.cpp.

◆ id()

QString QgsScientificNumericFormat::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().

Reimplemented from QgsBasicNumericFormat.

Definition at line 26 of file qgsscientificnumericformat.cpp.

◆ setNumberDecimalPlaces()

void QgsScientificNumericFormat::setNumberDecimalPlaces ( int places )

overridevirtual

Sets the maximum number of decimal places to show.

The places argument must be at least 1.

See also: numberDecimalPlaces(); setShowTrailingZeros()

Reimplemented from QgsBasicNumericFormat.

Definition at line 65 of file qgsscientificnumericformat.cpp.

◆ sortKey()

int QgsScientificNumericFormat::sortKey ( )

overridevirtual

Returns a sorting key value, where formats with a lower sort key will be shown earlier in lists.

Generally, subclasses should return QgsNumericFormat::sortKey() as their sorting key.

Reimplemented from QgsBasicNumericFormat.

Definition at line 36 of file qgsscientificnumericformat.cpp.

◆ visibleName()

QString QgsScientificNumericFormat::visibleName ( ) const

overridevirtual

Returns the translated, user-visible name for this format.

Reimplemented from QgsBasicNumericFormat.

Definition at line 31 of file qgsscientificnumericformat.cpp.
