Geometry
Wrappers around the underlying NSLayoutManager, but with a much more convenient API.
func enumerateLineFragments(for range: NSRange, block: (NSRect, NSRange) -> Void)
func enumerateLineFragments(for rect: NSRect, block: (NSRect, NSRange) -> Void)Ranges
Handy methods for computing ranges of text within the view.
func textRange(for rect: NSRect) -> NSRange
var visibleTextRange: NSRangeSelection
Convenience methods for computing selection ranges/locations.
var selectedTextRanges: [NSRange]
var selectedContinuousRange: NSRange?
var insertionLocation: Int?Style
Styling changes can be very expensive, this method is much faster in certain common cases.
func updateFont(_ newFont: NSFont, color newColor: NSColor)Bounding
Computing bounding rectangles of displayed text.
func boundingRect(for range: NSRange) -> NSRect?
func boundingRect(forGlyphRange range: NSRange) -> NSRect?
func boundingSelectionRects(forRange range: NSRange) -> [NSRect]Attributed Strings
Programmtic modification of the underlying attributed string in the NSTextStorage, with support for delegate callbacks and undo.
func replaceCharacters(in range: NSRange, with attributedString: NSAttributedString)
// with undo supported
func replaceString(in range: NSRange, with attributedString: NSAttributedString)Behavior
Changing NSTextView behaviors can be tricky, and often involve complex interactions with the whole system (NSLayoutManager, NSTextContainer, NSScrollView, etc).
public var wrapsTextToHorizontalBounds: BoolWorkarounds
// Fixes a widely-seen selection drawing artifact
