InvisibleRef

public struct InvisibleRef : InvisibleProtocol, GWeakCapturing

The GtkInvisible widget is used internally in GTK+, and is probably not very useful for application developers.

It is used for reliable pointer grabs and selection handling in the code for drag-and-drop.

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

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

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