CellRendererSpinProtocol

public protocol CellRendererSpinProtocol : CellRendererTextProtocol

Renders a spin button in a cell

GtkCellRendererSpin renders text in a cell like GtkCellRendererText from which it is derived. But while GtkCellRendererText offers a simple entry to edit the text, GtkCellRendererSpin offers a GtkSpinButton widget. Of course, that means that the text has to be parseable as a floating point number.

The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. GtkCellRendererSpin also has properties for the GtkCellRendererSpin:climb-rate and the number of GtkCellRendererSpin:digits to display. Other GtkSpinButton properties can be set in a handler for the GtkCellRendererediting-started`` signal.

The GtkCellRendererSpin cell renderer was added in GTK 2.10.

The CellRendererSpinProtocol protocol exposes the methods and properties of an underlying GtkCellRendererSpin instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CellRendererSpin. Alternatively, use CellRendererSpinRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying GtkCellRendererSpin instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • cell_renderer_spin_ptr Default implementation

    Typed pointer to the underlying GtkCellRendererSpin instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkCellRendererSpin instance.

    Declaration

    Swift

    var cell_renderer_spin_ptr: UnsafeMutablePointer<GtkCellRendererSpin>! { get }
  • Required Initialiser for types conforming to CellRendererSpinProtocol

    Declaration

    Swift

    init(raw: UnsafeMutableRawPointer)

CellRendererSpin Class

  • Bind a CellRendererSpinPropertyName source property to a given target object.

    Declaration

    Swift

    @discardableResult
    @inlinable
    func bind<Q, T>(property source_property: CellRendererSpinPropertyName, to target: T, _ target_property: Q, flags f: BindingFlags = .default, transformFrom transform_from: @escaping GLibObject.ValueTransformer = { $0.transform(destValue: $1) }, transformTo transform_to: @escaping GLibObject.ValueTransformer = { $0.transform(destValue: $1) }) -> BindingRef! where Q : PropertyNameProtocol, T : ObjectProtocol

    Parameters

    source_property

    the source property to bind

    target

    the target object to bind to

    target_property

    the target property to bind to

    flags

    the flags to pass to the Binding

    transform_from

    ValueTransformer to use for forward transformation

    transform_to

    ValueTransformer to use for backwards transformation

    Return Value

    binding reference or nil in case of an error

  • get(property:) Extension method

    Get the value of a CellRendererSpin property

    Declaration

    Swift

    @inlinable
    func get(property: CellRendererSpinPropertyName) -> GLibObject.Value

    Parameters

    property

    the property to get the value for

    Return Value

    the value of the named property

  • set(property:value:) Extension method

    Set the value of a CellRendererSpin property. Note that this will only have an effect on properties that are writable and not construct-only!

    Declaration

    Swift

    @inlinable
    func set(property: CellRendererSpinPropertyName, value v: GLibObject.Value)

    Parameters

    property

    the property to get the value for

    Return Value

    the value of the named property
