A numeric formatter which returns a simple text representation of a value.
RoundingType
Sets rounding type and behavior of the numberDecimalPlaces() setting.
@ DecimalPlaces
Maximum number of decimal places.
@ SignificantFigures
Maximum number of significant figures.
A context for numeric formats.
A numeric formatter allows for formatting a numeric value for display, using a variety of different f...
virtual QString formatDouble(double value, const QgsNumericFormatContext &context) const =0
Returns a formatted string representation of a numeric double value.
virtual int sortKey()
Returns a sorting key value, where formats with a lower sort key will be shown earlier in lists.
virtual QString visibleName() const =0
Returns the translated, user-visible name for this format.
virtual QString id() const =0
Returns a unique id for this numeric format.
virtual QgsNumericFormat * clone() const =0
Clones the format, returning a new object.
The class is used as a container of context for various read/write operations on other objects.
