Class FormulaEditDisplayConverter
java.lang.Object
org.eclipse.nebula.widgets.nattable.data.convert.ContextualDisplayConverter
org.eclipse.nebula.widgets.nattable.formula.FormulaEditDisplayConverter
- All Implemented Interfaces:
IDisplayConverter
IDisplayConverter
that needs to be registered for
DisplayMode.EDIT
in order to support editing of formulas without
formula execution.
Technically it does not perform a conversion, but returns the value of the
IDataProvider
that is wrapped by a FormulaDataProvider
via
FormulaDataProvider.getNativeDataValue(int, int)
.
configRegistry.registerConfigAttribute( CellConfigAttributes.DISPLAY_CONVERTER, new FormulaEditDisplayConverter(formulaDataProvider), DisplayMode.EDIT);

canonicalToDisplayValue
public Object canonicalToDisplayValue(ILayerCell cell, IConfigRegistry configRegistry, Object canonicalValue) Description copied from interface:IDisplayConverter
Convert backing data value to value to be displayed. Typically converts to a String for display. Use this method for contextual conversion.Note that on returning a different type than String,
toString()
will be called on the returned object to render the value for displaying.- Specified by:
canonicalToDisplayValue
in interfaceIDisplayConverter
- Specified by:
canonicalToDisplayValue
in classContextualDisplayConverter
- Parameters:
cell
- TheILayerCell
whose canonical value should be converted.configRegistry
- TheIConfigRegistry
of the NatTable to which theILayerCell
belongs.canonicalValue
- The data value from the backing data.- Returns:
- The converted value to display.
-
displayToCanonicalValue
public Object displayToCanonicalValue(ILayerCell cell, IConfigRegistry configRegistry, Object displayValue) Description copied from interface:IDisplayConverter
Convert from display value to value in the backing data structure.NOTE:
The type the display value is converted to must match the type in the setter of the backing bean/row object Use this method for contextual conversion.- Specified by:
displayToCanonicalValue
in interfaceIDisplayConverter
- Specified by:
displayToCanonicalValue
in classContextualDisplayConverter
- Parameters:
cell
- TheILayerCell
whose canonical value should be converted.configRegistry
- TheIConfigRegistry
of the NatTable to which theILayerCell
belongs.displayValue
- The display value that should be converted to the data value that matches the backing data.- Returns:
- The converted value to put to the backing data.
