Struct gdk4_wayland::WaylandDisplay [−][src]
pub struct WaylandDisplay(_);Expand description
The Wayland implementation of gdk::Display.
Beyond the regular gdk::Display API, the Wayland implementation
provides access to Wayland objects such as the wl_display with
wl_display(), the wl_compositor with
wl_compositor().
You can find out what Wayland globals are supported by a display
with query_registry().
Implements
Implementations
Sets the startup notification ID for a display.
This is usually taken from the value of the DESKTOP_STARTUP_ID
environment variable, but in some cases (such as the application not
being launched using exec()) it can come from other sources.
The startup ID is also what is used to signal that the startup is
complete (for example, when opening a window or when calling
Gdk::Display::notify_startup_complete()``).
startup_id
the startup notification ID (must be valid utf8)
This is supported on crate feature v4_4 only.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
