The value of the receiver’s cell as an attributed string.
- macOS 10.0+
If the control contains many cells (for example,
NSMatrix), this property contains the value of the currently selected cell. If the control is in the process of editing the affected cell, then it invokes the
validate method before getting the value.
If the cell is being edited, setting this property aborts all editing before setting the value. If the cell does not inherit from
NSAction, setting the property marks the cell’s interior as needing to be redisplayed;
NSAction performs its own updating of cells.
