Struct gdk4_wayland::WaylandDevice [−][src]
pub struct WaylandDevice(_);Expand description
The Wayland implementation of gdk::Device.
Beyond the regular gdk::Device API, the Wayland implementation
provides access to Wayland objects such as the wl_seat with
wl_seat(), the wl_keyboard with
wl_keyboard() and the wl_pointer with
wl_pointer().
Implements
Implementations
Returns the /dev/input/event* path of this device.
For gdk::Devices that possibly coalesce multiple hardware
devices (eg. mouse, keyboard, touch,…), this function
will return None.
This is most notably implemented for devices of type
gdk::InputSource::Pen, gdk::InputSource::TabletPad.
Returns
the /dev/input/event*
path of this device
This is supported on crate feature v4_4 only.

Tries to downcast to a reference of its subclass or interface implementor T. Read more
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
