GtkFontButton has a single CSS node with name fontbutton which contains a button node with the .font style class.

The FontButton type acts as a reference-counted owner of an underlying GtkFontButton instance. It provides the methods that can operate on this data type through FontButtonProtocol conformance. Use FontButton as a strong reference or owner of a GtkFontButton instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the FontButton instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 FontButton instance.

    Declaration

    Swift

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

    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 FontButton instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
