ToplevelRef

public struct ToplevelRef : ToplevelProtocol, GWeakCapturing

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

A GdkToplevel is a freestanding toplevel surface.

The GdkToplevel interface provides useful APIs for interacting with the windowing system, such as controlling maximization and size of the surface, setting icons and transient parents for dialogs.

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

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