Discussion
When the value of this property is true
, the expansion tool tip will expand; false
means the tool tip won’t expand. The default value is false
.
Expansion tooltips are shown when the cell cannot show the full content and the user hovers the pointer over the control. This is controlled by the NSCell
class method expansion

instances in a view-based NSTable
