ClosureExpressionRef Structure Reference
ClosureExpressionRef
public struct ClosureExpressionRef : ClosureExpressionProtocolAn expression using a custom GClosure to compute the value from
its parameters.
The ClosureExpressionRef type acts as a lightweight Swift reference to an underlying GtkClosureExpression instance.
It exposes methods that can operate on this data type through ClosureExpressionProtocol conformance.
Use ClosureExpressionRef only as an unowned reference to an existing GtkClosureExpression instance.
-
Untyped pointer to the underlying `GtkClosureExpression` instance.For type-safe access, use the generated, typed pointer
closure_expression_ptrproperty instead.Declaration
Swift
public let ptr: UnsafeMutableRawPointer!

Swift
@inlinable init(_ p: UnsafeMutablePointer<GtkClosureExpression>) -
