Struct gdk4_wayland::WaylandSurface [−][src]
pub struct WaylandSurface(_);
Expand description
The Wayland implementation of gdk::Surface
.
Beyond the gdk::Surface
API, the Wayland implementation offers
access to the Wayland wl_surface
object with
WaylandSurfaceExtManual::wl_surface()
.

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
