type INSLayoutManagerDelegate = interface
    interface INativeObject
    interface IDisposable

Derived: UIKit.NSLayoutManagerDelegate

Attributes: ProtocolAttribute ProtocolMemberAttribute

Implements: INativeObject IDisposable

Properties

Name	Description
Handle	Handle (pointer) to the unmanaged object representation. (Inherited from INativeObject)

Methods

Name	Description
DidChangeGeometry(NSLayoutManager, NSTextContainer, CGSize)	The geometry of `textContainer` changed from `oldSize`, and `layoutManager` will invalidate the layout.
DidCompleteLayout(NSLayoutManager, NSTextContainer, Boolean)	Indicates that the specified NSLayoutManager has finished laying out text in the specified text container.
DidInvalidatedLayout(NSLayoutManager)	Indicates that the NSLayoutManager has invalidated layout information (not glyph information).
GetBoundingBox(NSLayoutManager, UIntPtr, NSTextContainer, CGRect, CGPoint, UIntPtr)
GetLineSpacingAfterGlyph(NSLayoutManager, UIntPtr, CGRect)
GetParagraphSpacingAfterGlyph(NSLayoutManager, UIntPtr, CGRect)
GetParagraphSpacingBeforeGlyph(NSLayoutManager, UIntPtr, CGRect)
ShouldBreakLineByHyphenatingBeforeCharacter(NSLayoutManager, UIntPtr)	Whether a line should break with a hyphen at the specified point. Called frequently.
ShouldBreakLineByWordBeforeCharacter(NSLayoutManager, UIntPtr)	Whether a line should have a soft line break. Called frequently.
ShouldGenerateGlyphs(NSLayoutManager, IntPtr, IntPtr, IntPtr, UIFont, NSRange)	When overridden, allows the app developer to customize the initial glyph generation process.
ShouldSetLineFragmentRect(NSLayoutManager, CGRect, CGRect, NFloat, NSTextContainer, NSRange)
ShouldUseAction(NSLayoutManager, NSControlCharacterAction, UIntPtr)	The control character action for the control character at the specified index.
