Detailed Description
A numeric formatter allows for formatting a numeric value for display, using a variety of different formatting techniques (e.g.
as scientific notation, currency values, percentage values, etc)
This is an abstract base class and will always need to be subclassed.

Member Function Documentation
◆ clone()
|
pure virtual |
Clones the format, returning a new object.
The caller takes ownership of the returned object.
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ configuration()
|
pure virtual |
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.
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ create()
|
pure virtual |
Creates a new copy of the format, using the supplied configuration.
The caller takes ownership of the returned object.
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ formatDouble()
|
pure virtual |
Returns a formatted string representation of a numeric double value.
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ id()
|
pure virtual |
Returns a unique id for this numeric format.
This id is used to identify this numeric format in the registry with QgsNumericFormatRegistry::format().
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ operator!=()
| bool QgsNumericFormat::operator!= | ( | const QgsNumericFormat & | other | ) | const |
Definition at line 71 of file qgsnumericformat.cpp.
◆ operator==()
| bool QgsNumericFormat::operator== | ( | const QgsNumericFormat & | other | ) | const |
Definition at line 66 of file qgsnumericformat.cpp.
◆ sortKey()
|
virtual |
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 in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
Definition at line 48 of file qgsnumericformat.cpp.
◆ suggestSampleValue()
|
virtual |
Returns a suggested sample value which nicely represents the current format configuration.
Reimplemented in QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsCurrencyNumericFormat, and QgsBearingNumericFormat.
Definition at line 53 of file qgsnumericformat.cpp.
◆ visibleName()
|
pure virtual |
Returns the translated, user-visible name for this format.
Implemented in QgsScientificNumericFormat, QgsPercentageNumericFormat, QgsFractionNumericFormat, QgsFallbackNumericFormat, QgsCurrencyNumericFormat, QgsBearingNumericFormat, and QgsBasicNumericFormat.
◆ writeXml()
| void QgsNumericFormat::writeXml | ( | QDomElement & | element, |
| QDomDocument & | document, | ||
| const QgsReadWriteContext & | context | ||
| ) | const |
Writes the format to an XML element.
