Possible constraints include confining pointer * motions to a given region, or locking it to its current position. * * In order to constrain the pointer, a client must first bind the global * interface "wp_pointer_constraints" which, if a compositor supports pointer * constraints, is exposed by the registry. Using the bound global object, the * client uses the request that corresponds to the type of constraint it wants * to make. See wp_pointer_constraints for more details. * * 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. * * @section page_ifaces_pointer_constraints_unstable_v1 Interfaces * - @subpage page_iface_zwp_pointer_constraints_v1 - constrain the movement of * a pointer * - @subpage page_iface_zwp_locked_pointer_v1 - receive relative pointer motion * events * - @subpage page_iface_zwp_confined_pointer_v1 - confined pointer object * @section page_copyright_pointer_constraints_unstable_v1 Copyright *
