Returns the expansion cell frame for the receiver.
- macOS 10.5+
The frame for the receiver.
The view in which the receiver will be drawn.
The expansion cell frame for the receiver. If the frame is not too small, return an empty rect (
NSZero), and no expansion tool tip view will be shown.
This method allows the cell to return an expansion cell frame if
cell is too small for the entire contents in the view. When the mouse is hovered over the cell in certain controls, the full cell contents are shown in a special floating tool tip view. By default,
NSZero, while some subclasses (such as
NSText) will return the proper frame when required.
