touchpad gestures
A global interface to provide semantic touchpad gestures for a given pointer.
Three gestures are currently supported: swipe, pinch, and hold. Pinch and swipe gestures follow a three-stage cycle: begin, update, end, hold gestures follow a two-stage cycle: begin and end. All gestures are identified by a unique id.
Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset.

Underlying wl_proxy type and properties of a proxy_t that affect construction, destruction, and event handling
Enumerator | |
---|---|
standard | 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. |
display | 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. |
foreign | 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. |
proxy_wrapper | 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 hold gesture
pointer |
Create a hold gesture object. See the wl_pointer_gesture_hold interface for details.

Get the id of a proxy object.
zwp_pointer_gesture_pinch_v1_t zwp_pointer_gestures_v1_t::get_pinch_gesture | ( | pointer_t const & | pointer | ) |
get pinch gesture
pointer |
Create a pinch gesture object. See the wl_pointer_gesture_pinch interface for details.

zwp_pointer_gesture_swipe_v1_t zwp_pointer_gestures_v1_t::get_swipe_gesture | ( | pointer_t const & | pointer | ) |
get swipe gesture
pointer |
Create a swipe gesture object. See the wl_pointer_gesture_swipe interface for details.

inherited |
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.

Note that display_t instances cannot be released this way. Attempts to do so are ignored.

destroy the pointer gesture object
Destroy the pointer gesture object. Swipe, pinch and hold objects created via this gesture object remain valid.

Assign a proxy to an event queue.
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.
