Instance Method

frameOfOutlineCell(atRow:)

Returns the frame of the outline cell for a given row.

Declaration

func frameOfOutlineCell(atRow row: Int) -> NSRect

Parameters

row

The index of the row for which to return the frame.

Return Value

The frame of the outline cell for the row at index row, considering the current indentation and the value in the indentationMarkerFollowsCell property. If the row at index row is not an expandable row, returns NSZeroRect.

Discussion

You can override this method in a subclass to return a custom frame for the outline button cell. If your override returns an empty rect, no outline cell is drawn for that row. You might do that, for example, so that the disclosure triangle will not be shown for a row that should never be expanded.
