Instance Property

usesSingleLineMode

A Boolean value indicating whether the cell restricts layout and rendering of text to a single line.

Declaration

var usesSingleLineMode: Bool { get set }

Discussion

When the value of this property is true, text layout and rendering is restricted to a single line. In addition, the cell ignores the return value from wraps, interprets NSLineBreakMode.byWordWrapping and NSLineBreakMode.byCharWrapping returned by lineBreakMode as NSLineBreakMode.byClipping, and configures the field editor to ignore key binding commands that insert paragraph and line separators.

The field editor bound to a single-line cell filters out paragraph and line separator insertion from user actions. Cells in single-line mode use the fixed baseline layout. The text baseline position is determined solely by the control size regardless of content font style or size.
