ExpressionWatchRef

public struct ExpressionWatchRef : ExpressionWatchProtocol

An opaque structure representing a watched GtkExpression.

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

The ExpressionWatchRef type acts as a lightweight Swift reference to an underlying GtkExpressionWatch instance. It exposes methods that can operate on this data type through ExpressionWatchProtocol conformance. Use ExpressionWatchRef only as an unowned reference to an existing GtkExpressionWatch instance.

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

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