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.
