BoolFilter

open class BoolFilter : Filter, BoolFilterProtocol

GtkBoolFilter evaluates a boolean GtkExpression to determine whether to include items.

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

    Declaration

    Swift

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

    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 BoolFilter instance.

    Declaration

    Swift

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

    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 BoolFilter instance.

    Declaration

    Swift

    @inlinable
override 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 BoolFilter instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
