AlignmentProtocol

public protocol AlignmentProtocol : BinProtocol

The GtkAlignment widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.

The scale settings are used to specify how much the child widget should expand to fill the space allocated to the GtkAlignment. The values can range from 0 (meaning the child doesn’t expand at all) to 1 (meaning the child expands to fill all of the available space).

The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.

GtkAlignment has been deprecated in 3.14 and should not be used in newly-written code. The desired effect can be achieved by using the GtkWidget:halign, GtkWidget:valign and GtkWidget:margin properties on the child widget.

The AlignmentProtocol protocol exposes the methods and properties of an underlying GtkAlignment 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 Alignment. Alternatively, use AlignmentRef as a lighweight, unowned reference if you already have an instance you just want to use.

Alignment Class: AlignmentProtocol extension (methods and fields)

  • Gets the padding on the different sides of the widget. See gtk_alignment_set_padding ().

    get_padding is deprecated: Use #GtkWidget alignment and margin properties

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func getPadding(paddingTop: UnsafeMutablePointer<guint>! = nil, paddingBottom: UnsafeMutablePointer<guint>! = nil, paddingLeft: UnsafeMutablePointer<guint>! = nil, paddingRight: UnsafeMutablePointer<guint>! = nil)
    Show on GitHub

  • Sets the GtkAlignment values.

    set is deprecated: Use #GtkWidget alignment and margin properties

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func set(xalign: Double, yalign: Double, xscale: Double, yscale: Double)
    Show on GitHub

  • Sets the padding on the different sides of the widget. The padding adds blank space to the sides of the widget. For instance, this can be used to indent the child widget towards the right by adding padding on the left.

    set_padding is deprecated: Use #GtkWidget alignment and margin properties

    Declaration

    Swift

    @available(*, deprecated)
@inlinable
func setPadding(paddingTop: Int, paddingBottom: Int, paddingLeft: Int, paddingRight: Int)
