ConstraintTarget

open class ConstraintTarget : ConstraintTargetProtocol

The GtkConstraintTarget interface is implemented by objects that can be used as source or target in GtkConstraints.

Besides GtkWidget, it is also implemented by GtkConstraintGuide.

The ConstraintTarget type acts as an owner of an underlying GtkConstraintTarget instance. It provides the methods that can operate on this data type through ConstraintTargetProtocol conformance. Use ConstraintTarget as a strong reference or owner of a GtkConstraintTarget instance.

  • ptr 
    Untyped pointer to the underlying `GtkConstraintTarget` instance.

    For type-safe access, use the generated, typed pointer constraint_target_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

  • Designated initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkConstraintTarget>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkConstraintTarget>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init!(_ op: UnsafePointer<GtkConstraintTarget>?)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init!(_ op: UnsafeMutablePointer<GtkConstraintTarget>?)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from the underlying C data type. GtkConstraintTarget does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the ConstraintTarget instance.

    Declaration

    Swift

    @inlinable
public init(retaining op: UnsafeMutablePointer<GtkConstraintTarget>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements ConstraintTargetProtocol GtkConstraintTarget does not allow reference counting.

    Declaration

    Swift

    @inlinable
public init<T>(_ other: T) where T : ConstraintTargetProtocol

    Parameters

    other

    an instance of a related type that implements ConstraintTargetProtocol

    Parameters

    cPointer

    pointer to the underlying object
