context object for keyboard shortcuts inhibitor

A keyboard shortcuts inhibitor instructs the compositor to ignore its own keyboard shortcuts when the associated surface has keyboard focus. As a result, when the surface has keyboard focus on the given seat, it will receive all key events originating from the specified seat, even those which would normally be caught by the compositor for its own shortcuts.

The Wayland compositor is however under no obligation to disable all of its shortcuts, and may keep some special key combo for its own use, including but not limited to one allowing the user to forcibly restore normal keyboard events routing in the case of an unwilling client. The compositor may also use the same key combo to reactivate an existing shortcut inhibitor that was previously deactivated on user request.

When the compositor restores its own keyboard shortcuts, an 'inactive' event is emitted to notify the client that the keyboard shortcuts inhibitor is not effectively active for the surface and seat any more, and the client should not expect to receive all keyboard events.

When the keyboard shortcuts inhibitor is inactive, the client has no way to forcibly reactivate the keyboard shortcuts inhibitor.

The user can chose to re-enable a previously deactivated keyboard shortcuts inhibitor using any mechanism the compositor may offer, in which case the compositor will send an 'active' event to notify the client.

If the surface is destroyed, unmapped, or loses the seat's keyboard focus, the keyboard shortcuts inhibitor becomes irrelevant and the compositor will restore its own keyboard shortcuts but no 'inactive' event is emitted in this case.

Underlying wl_proxy type and properties of a proxy_t that affect construction, destruction, and event handling

Enumerator

C pointer is a standard type compatible with wl_proxy*. Events are dispatched and it is destructed when the proxy_t is destructed. User data is set.
C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is called when the proxy_t is destructed. User data is set.
C pointer is a standard type compatible with wl_proxy*, but another library owns it and it should not be touched in a way that could affect the operation of the other library. No events are dispatched, wl_proxy_destroy is not called when the proxy_t is destructed, user data is not touched. Consequently, there is no reference counting for the proxy_t. Lifetime of such wrappers should preferably be short to minimize the chance that the owning library decides to destroy the wl_proxy.
C pointer is a wl_proxy* that was constructed with wl_proxy_create_wrapper. No events are dispatched, wl_proxy_wrapper_destroy is called when the proxy_t is destroyed. Reference counting is active. A reference to the proxy_t creating this proxy wrapper is held to extend its lifetime until after the proxy wrapper is destroyed.

Get a pointer to the underlying C struct.

Returns

The underlying wl_proxy wrapped by this proxy_t if it exists, otherwise an exception is thrown

Get the interface name (class) of a proxy object.

Returns

The interface name of the object associated with the proxy

Get the id of a proxy object.

Returns

The id the object associated with the proxy

Get the protocol object version of a proxy object. Gets the protocol object version of a proxy object, or 0 if the proxy was created with unversioned API.

A returned value of 0 means that no version information is available, so the caller must make safe assumptions about the object's real version.

display_t will always return version 0.

Returns

The protocol object version of the proxy or 0

wrapper_type wayland::proxy_t::get_wrapper_type () const [inline], [inherited]

Get the type of a proxy object.

shortcuts are inhibited This event indicates that the shortcut inhibitor is active.

The compositor sends this event every time compositor shortcuts are inhibited on behalf of the surface. When active, the client may receive input events normally reserved by the compositor (see zwp_keyboard_shortcuts_inhibitor_v1).

This occurs typically when the initial request 'inhibit_shortcuts' first becomes active or when the user instructs the compositor to re-enable and existing shortcuts inhibitor using any mechanism offered by the compositor.

shortcuts are restored This event indicates that the shortcuts inhibitor is inactive, normal shortcuts processing is restored by the compositor.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

Check whether two wrappers refer to different objects.

Check whether two wrappers refer to the same object.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

Release the wrapped object (if any), making this an empty wrapper. Note that display_t instances cannot be released this way. Attempts to do so are ignored.

Examples
foreign_display.cpp.

Assign a proxy to an event queue.

Parameters

queue The event queue that will handle this proxy

Assign proxy to event queue. Events coming from proxy will be queued in queue instead of the display's main queue.

See also: display_t::dispatch_queue().

Examples
proxy_wrapper.cpp.
