ExpressionWatch

open class ExpressionWatch : ExpressionWatchProtocol

An opaque structure representing a watched GtkExpression.

The contents of GtkExpressionWatch should only be accessed through the provided API.

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

  • ptr 
    Untyped pointer to the underlying `GtkExpressionWatch` instance.

    For type-safe access, use the generated, typed pointer expression_watch_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

  • Designated initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ExpressionWatch instance.

    Declaration

    Swift

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

    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 ExpressionWatch instance.

    Declaration

    Swift

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

    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 ExpressionWatch instance.

    Declaration

    Swift

    @inlinable
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 ExpressionWatch instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. Will retain GtkExpressionWatch. i.e., ownership is transferred to the ExpressionWatch instance.

    Declaration

  • Reference intialiser for a related type that implements ExpressionWatchProtocol Will retain GtkExpressionWatch.

    Declaration

    Swift

    @inlinable
public init<T>(_ other: T) where T : ExpressionWatchProtocol

    Parameters

    other

    an instance of a related type that implements ExpressionWatchProtocol
