QgsScientificNumericFormat::QgsScientificNumericFormat | ( | ) |
Default constructor.
Definition at line 21 of file qgsscientificnumericformat.cpp.
|
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.
|
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.
|
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.
|
overridevirtual |
Returns a formatted string representation of a numeric double value.
Reimplemented from QgsBasicNumericFormat.
Definition at line 41 of file qgsscientificnumericformat.cpp.
|
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.
|
overridevirtual |
Sets the maximum number of decimal places to show.
The places argument must be at least 1.
Reimplemented from QgsBasicNumericFormat.
Definition at line 65 of file qgsscientificnumericformat.cpp.
|
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.
