PrintOperationPreviewRef Structure Reference
PrintOperationPreviewRef
public struct PrintOperationPreviewRef : PrintOperationPreviewProtocolGtkPrintOperationPreview is the interface that is used to
implement print preview.
A GtkPrintOperationPreview object is passed to the
[signalGtk.PrintOperation::preview] signal by
[classGtk.PrintOperation].
The PrintOperationPreviewRef type acts as a lightweight Swift reference to an underlying GtkPrintOperationPreview instance.
It exposes methods that can operate on this data type through PrintOperationPreviewProtocol conformance.
Use PrintOperationPreviewRef only as an unowned reference to an existing GtkPrintOperationPreview instance.
-
Untyped pointer to the underlying `GtkPrintOperationPreview` instance.For type-safe access, use the generated, typed pointer
print_operation_preview_ptrproperty instead.Declaration
Swift
public let ptr: UnsafeMutableRawPointer!
