Types ¶
type InputTimestamps ¶
InputTimestamps : context object for input timestamps
Provides high-resolution timestamp events for a set of subscribed input events. The set of subscribed input events is determined by the zwp_input_timestamps_manager_v1 request used to create this object.
func NewInputTimestamps ¶
func NewInputTimestamps(ctx *client.Context) *InputTimestamps
NewInputTimestamps : context object for input timestamps
Provides high-resolution timestamp events for a set of subscribed input events. The set of subscribed input events is determined by the zwp_input_timestamps_manager_v1 request used to create this object.
func (*InputTimestamps) Destroy ¶
func (i *InputTimestamps) Destroy() error
Destroy : destroy the input timestamps object
Informs the server that the client will no longer be using this protocol object. After the server processes the request, no more timestamp events will be emitted.
func (*InputTimestamps) Dispatch ¶
func (i *InputTimestamps) Dispatch(opcode uint32, fd int, data []byte)
func (*InputTimestamps) SetTimestampHandler ¶
func (i *InputTimestamps) SetTimestampHandler(f InputTimestampsTimestampHandlerFunc)
SetTimestampHandler : sets handler for InputTimestampsTimestampEvent
type InputTimestampsManager ¶
InputTimestampsManager : context object for high-resolution input timestamps
A global interface used for requesting high-resolution timestamps for input events.
func NewInputTimestampsManager ¶
func NewInputTimestampsManager(ctx *client.Context) *InputTimestampsManager
NewInputTimestampsManager : context object for high-resolution input timestamps
A global interface used for requesting high-resolution timestamps for input events.
func (*InputTimestampsManager) Destroy ¶
func (i *InputTimestampsManager) Destroy() error
Destroy : destroy the input timestamps manager object
Informs the server that the client will no longer be using this protocol object. Existing objects created by this object are not affected.
func (*InputTimestampsManager) GetKeyboardTimestamps ¶
func (i *InputTimestampsManager) GetKeyboardTimestamps(keyboard *client.Keyboard) (*InputTimestamps, error)
GetKeyboardTimestamps : subscribe to high-resolution keyboard timestamp events
Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_keyboard events that carry a timestamp.
If the associated wl_keyboard object is invalidated, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.
keyboard: the wl_keyboard object for which to get timestamp events
func (*InputTimestampsManager) GetPointerTimestamps ¶
func (i *InputTimestampsManager) GetPointerTimestamps(pointer *client.Pointer) (*InputTimestamps, error)
GetPointerTimestamps : subscribe to high-resolution pointer timestamp events
Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_pointer events that carry a timestamp.
If the associated wl_pointer object is invalidated, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.
pointer: the wl_pointer object for which to get timestamp events
func (*InputTimestampsManager) GetTouchTimestamps ¶
func (i *InputTimestampsManager) GetTouchTimestamps(touch *client.Touch) (*InputTimestamps, error)
GetTouchTimestamps : subscribe to high-resolution touch timestamp events
Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_touch events that carry a timestamp.
If the associated wl_touch object becomes invalid, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.
touch: the wl_touch object for which to get timestamp events
type InputTimestampsTimestampEvent ¶
InputTimestampsTimestampEvent : high-resolution timestamp event
The timestamp event is associated with the first subsequent input event carrying a timestamp which belongs to the set of input events this object is subscribed to.
The timestamp provided by this event is a high-resolution version of the timestamp argument of the associated input event. The provided timestamp is in the same clock domain and is at least as accurate as the associated input event timestamp.
The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999].
type InputTimestampsTimestampHandlerFunc ¶
