Requisition

open class Requisition : RequisitionProtocol

A GtkRequisition represents the desired size of a widget. See GtkWidget’s geometry management section for more information.

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

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

    For type-safe access, use the generated, typed pointer requisition_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 Requisition instance.

    Declaration

    Swift

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

    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 Requisition instance.

    Declaration

    Swift

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

    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 Requisition 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 Requisition 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 Requisition instance.

    Declaration

    Swift

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

    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 Requisition instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements RequisitionProtocol GtkRequisition does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements RequisitionProtocol

  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to RequisitionProtocol.

    Declaration

    Swift

    @inlinable
public init<T>(cPointer p: UnsafeMutablePointer<T>)

    Parameters

    cPointer

    pointer to the underlying object

  • Unsafe typed, retaining initialiser. Do not use unless you know the underlying data type the pointer points to conforms to RequisitionProtocol.

    Declaration

    Swift

    @inlinable
public init<T>(retainingCPointer cPointer: UnsafeMutablePointer<T>)

    Parameters

    cPointer

    pointer to the underlying object
