BoolFilterProtocol

public protocol BoolFilterProtocol : FilterProtocol

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

The BoolFilterProtocol protocol exposes the methods and properties of an underlying GtkBoolFilter 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 BoolFilter. Alternatively, use BoolFilterRef as a lighweight, unowned reference if you already have an instance you just want to use.

BoolFilter Class

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

    Declaration

    Swift

    @discardableResult
@inlinable
func bind<Q, T>(property source_property: BoolFilterPropertyName, 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 BoolFilter property

    Declaration

    Swift

    @inlinable
func get(property: BoolFilterPropertyName) -> 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 BoolFilter property. Note that this will only have an effect on properties that are writable and not construct-only!

    Declaration

    Swift

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

    Parameters

    property

    the property to get the value for

    Return Value

    the value of the named property

BoolFilter Class: BoolFilterProtocol extension (methods and fields)

  • getExpression() Extension method

    Gets the expression that the filter uses to evaluate if an item should be filtered.

    Declaration

    Swift

    @inlinable
func getExpression() -> ExpressionRef!
    Show on GitHub
  • getInvert() Extension method

    Returns whether the filter inverts the expression.

    Declaration

    Swift

    @inlinable
func getInvert() -> Bool
    Show on GitHub
  • set(expression:) Extension method

    Sets the expression that the filter uses to check if items should be filtered.

    The expression must have a value type of G_TYPE_BOOLEAN.

    Declaration

    Swift

    @inlinable
func set(expression: ExpressionRef? = nil)
    Show on GitHub
  • set(expression:) Extension method

    Sets the expression that the filter uses to check if items should be filtered.

    The expression must have a value type of G_TYPE_BOOLEAN.

    Declaration

    Swift

    @inlinable
func set<ExpressionT>(expression: ExpressionT?) where ExpressionT : ExpressionProtocol
    Show on GitHub
  • set(invert:) Extension method

    Sets whether the filter should invert the expression.

    Declaration

    Swift

    @inlinable
func set(invert: Bool)
    Show on GitHub
  • expression Extension method

    The boolean expression to evaluate on item.

    Declaration

    Swift

    @inlinable
var expression: ExpressionRef! { get nonmutating set }
    Show on GitHub
  • invert Extension method

    If the expression result should be inverted.
