DisplayRef
public struct DisplayRef : DisplayProtocol, GWeakCapturing
The DisplayRef
type acts as a lightweight Swift reference to an underlying GdkDisplay
instance.
It exposes methods that can operate on this data type through DisplayProtocol
conformance.
Use DisplayRef
only as an unowned
reference to an existing GdkDisplay
instance.
GdkDisplay
objects are the GDK representation of a workstation.
Their purpose are two-fold:
- To manage and provide information about input devices (pointers, keyboards, etc)
- To manage and provide information about output devices (monitors, projectors, etc)
Most of the input device handling has been factored out into separate
[classGdk.Seat
] objects. Every display has a one or more seats, which
can be accessed with [methodGdk.Display.get_default_seat
] and
[methodGdk.Display.list_seats
].
Output devices are represented by [classGdk.Monitor
] objects, which can
be accessed with [methodGdk.Display.get_monitor_at_surface
] and similar APIs.

Untyped pointer to the underlying `GdkDisplay` instance.
For type-safe access, use the generated, typed pointer
display_ptr
property instead.Declaration
