Properties

children?

optional children?: ReactNode

Defined in: packages/react/src/generated/jsx.ts:9797

Inherited from

GtkGestureProps.children

---

name?

optional name?: string | null

Defined in: packages/react/src/generated/jsx.ts:9764

The name for this controller, typically used for debugging purposes.

Inherited from

GtkGestureProps.name

---

nPoints?

optional nPoints?: number

Defined in: packages/react/src/generated/jsx.ts:10101

The number of touch points that trigger recognition on this gesture.

Inherited from

GtkGestureProps.nPoints

---

onAngleChanged?

optional onAngleChanged?: (angle, angleDelta, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10222

Emitted when the angle between both tracked points changes.

Parameters

Parameter	Type
angle	number
angleDelta	number
self	GestureRotate

Returns

void | null

---

onBegin?

optional onBegin?: (sequence, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10113

Emitted when the gesture is recognized.

This means the number of touch sequences matches Gesture.n-points.

Note: These conditions may also happen when an extra touch (eg. a third touch on a 2-touches gesture) is lifted, in that situation sequence won't pertain to the current set of active touches, so don't rely on this being true.

Parameters

Parameter	Type
sequence	EventSequence
self	Gesture

Returns

void | null

Inherited from

GtkGestureProps.onBegin

---

onCancel?

optional onCancel?: (sequence, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10126

Emitted whenever a sequence is cancelled.

This usually happens on active touches when EventController.reset is called on gesture (manually, due to grabs...), or the individual sequence was claimed by parent widgets' controllers (see Gesture.set_sequence_state).

gesture must forget everything about sequence as in response to this signal.

Parameters

Parameter	Type
sequence	EventSequence
self	Gesture

Returns

void | null

Inherited from

GtkGestureProps.onCancel

---

onEnd?

optional onEnd?: (sequence, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10138

Emitted when gesture either stopped recognizing the event sequences as something to be handled, or the number of touch sequences became higher or lower than Gesture.n-points.

Note: sequence might not pertain to the group of sequences that were previously triggering recognition on gesture (ie. a just pressed touch sequence that exceeds Gesture.n-points). This situation may be detected by checking through Gesture.handles_sequence.

Parameters

Parameter	Type
sequence	EventSequence
self	Gesture

Returns

void | null

Inherited from

GtkGestureProps.onEnd

---

onNotify?

optional onNotify?: (pspec, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:9796

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with %G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in ::notify being emitted, even if the new value is the same as the old. If they did pass %G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

|[ g_signal_connect (text_view->buffer, "notify::paste-target-list", G_CALLBACK (gtk_text_view_target_list_notify), text_view) ]|

It is important to note that you must use [canonical parameter names]GObjectParamSpec#parameter-names as detail strings for the notify signal.

Parameters

Parameter	Type
pspec	ParamSpec
self	EventController

Returns

void | null

Inherited from

GtkGestureProps.onNotify

---

onSequenceStateChanged?

optional onSequenceStateChanged?: (sequence, state, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10145

Emitted whenever a sequence state changes.

See Gesture.set_sequence_state to know more about the expectable sequence lifetimes.

Parameters

Parameter	Type
sequence	EventSequence
state	EventSequenceState
self	Gesture

Returns

void | null

Inherited from

GtkGestureProps.onSequenceStateChanged

---

onUpdate?

optional onUpdate?: (sequence, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:10151

Emitted whenever an event is handled while the gesture is recognized.

sequence is guaranteed to pertain to the set of active touches.

Parameters

Parameter	Type
sequence	EventSequence
self	Gesture

Returns

void | null

Inherited from

GtkGestureProps.onUpdate

---

propagationLimit?

optional propagationLimit?: PropagationLimit

Defined in: packages/react/src/generated/jsx.ts:9766

The limit for which events this controller will handle.

Inherited from

GtkGestureProps.propagationLimit

---

propagationPhase?

optional propagationPhase?: PropagationPhase

Defined in: packages/react/src/generated/jsx.ts:9768

The propagation phase at which this controller will handle events.

Inherited from

GtkGestureProps.propagationPhase

---

ref?

optional ref?: Ref<GestureRotate>

Defined in: packages/react/src/generated/jsx.ts:10223

Overrides

GtkGestureProps.ref
