Displaying Cell Values
Every NSCell
that displays text has a value associated with it. The NSCell
object stores that value as an object of potentially any type, displays it as an NSString
object, and returns it as a primary value or string object, according to what’s requested (intValue
, floatValue
, stringValue
, and so on). Formatters are objects associated with NSCell
objects (through setFormatter:
) that translate a cell’s object value to its it textual representation and convert what users type into the underlying object. NSCell
objects have built-in formatters to handle common string and numeric (int
, float
, double
) translations. In addition, you can implement your own formatters to provide specialized object translation; see Data Formatting Guide.
The text that an NSCell
object displays and stores can be an attributed string. Several methods help to set and get attributed-string values, including setAttributedStringValue:
and setImportsGraphics:
