Rectangle

open class Rectangle : RectangleProtocol

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

A GdkRectangle data type for representing rectangles.

GdkRectangle is identical to cairo_rectangle_t. Together with Cairo’s cairo_region_t data type, these are the central types for representing sets of pixels.

The intersection of two rectangles can be computed with [methodGdk.Rectangle.intersect]; to find the union of two rectangles use [methodGdk.Rectangle.union].

The cairo_region_t type provided by Cairo is usually used for managing non-rectangular clipping of graphical operations.

The Graphene library has a number of other data types for regions and volumes in 2D and 3D.

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

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

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

    Declaration

    Swift

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

    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 Rectangle instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Rectangle instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object

  • 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 Rectangle instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Rectangle instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements RectangleProtocol GdkRectangle does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements RectangleProtocol
