RequisitionRef

public struct RequisitionRef : RequisitionProtocol

A GtkRequisition-struct represents the desired size of a widget. See GtkWidget’s geometry management section for more information.

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

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

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