ConstantExpressionRef Structure Reference
ConstantExpressionRef
public struct ConstantExpressionRef : ConstantExpressionProtocolA constant value in a GtkExpression.
The ConstantExpressionRef type acts as a lightweight Swift reference to an underlying GtkConstantExpression instance.
It exposes methods that can operate on this data type through ConstantExpressionProtocol conformance.
Use ConstantExpressionRef only as an unowned reference to an existing GtkConstantExpression instance.
-
Untyped pointer to the underlying `GtkConstantExpression` instance.For type-safe access, use the generated, typed pointer
constant_expression_ptrproperty instead.Declaration
Swift
