Properties

actions?

optional actions: DragAction

Defined in: packages/react/src/generated/jsx.ts:9853

The actions that are supported by drag operations from the source.

Note that you must handle the DragSource.:drag-end signal if the actions include %GDK_ACTION_MOVE.

---

button?

optional button: number

Defined in: packages/react/src/generated/jsx.ts:10294

Mouse button number to listen to, or 0 to listen for any button.

Inherited from

GtkGestureSingleProps.button

---

children?

optional children: ReactNode

Defined in: packages/react/src/generated/jsx.ts:9842

Inherited from

GtkGestureSingleProps.children

---

content?

optional content: ContentProvider | null

Defined in: packages/react/src/generated/jsx.ts:9855

The data that is offered by drag operations from this source.

---

exclusive?

optional exclusive: boolean

Defined in: packages/react/src/generated/jsx.ts:10300

Whether the gesture is exclusive.

Exclusive gestures only listen to pointer and pointer emulated events.

Inherited from

GtkGestureSingleProps.exclusive

---

icon?

optional icon: Paintable | null

Defined in: packages/react/src/jsx.ts:1341

Paintable to use as the drag icon

---

iconHotX?

optional iconHotX: number

Defined in: packages/react/src/jsx.ts:1343

X offset of the hotspot within the drag icon

---

iconHotY?

optional iconHotY: number

Defined in: packages/react/src/jsx.ts:1345

Y offset of the hotspot within the drag icon

---

name?

optional name: string | null

Defined in: packages/react/src/generated/jsx.ts:9809

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

Inherited from

GtkGestureSingleProps.name

---

nPoints?

optional nPoints: number

Defined in: packages/react/src/generated/jsx.ts:10156

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

Inherited from

GtkGestureSingleProps.nPoints

---

onBegin()?

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

Defined in: packages/react/src/generated/jsx.ts:10168

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

GtkGestureSingleProps.onBegin

---

onCancel()?

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

Defined in: packages/react/src/generated/jsx.ts:10181

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

GtkGestureSingleProps.onCancel

---

onDragBegin()?

optional onDragBegin: (drag, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:9862

Emitted on the drag source when a drag is started.

It can be used to e.g. set a custom drag icon with DragSource.set_icon.

Parameters

Parameter	Type
drag	Drag
self	DragSource

Returns

void | null

---

onDragCancel()?

optional onDragCancel: (drag, reason, self) => boolean | null

Defined in: packages/react/src/generated/jsx.ts:9870

Emitted on the drag source when a drag has failed.

The signal handler may handle a failed drag operation based on the type of error. It should return %TRUE if the failure has been handled and the default "drag operation failed" animation should not be shown.

Parameters

Parameter	Type
drag	Drag
reason	DragCancelReason
self	DragSource

Returns

boolean | null

---

onDragEnd()?

optional onDragEnd: (drag, deleteData, self) => void | null

Defined in: packages/react/src/generated/jsx.ts:9878

Emitted on the drag source when a drag is finished.

A typical reason to connect to this signal is to undo things done in DragSource.:prepare or DragSource.:drag-begin handlers.

Parameters

Parameter	Type
drag	Drag
deleteData	boolean
self	DragSource

Returns

void | null

---

onEnd()?

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

Defined in: packages/react/src/generated/jsx.ts:10193

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

GtkGestureSingleProps.onEnd

---

onNotify()?

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

Defined in: packages/react/src/generated/jsx.ts:9841

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

GtkGestureSingleProps.onNotify

---

onPrepare()?

optional onPrepare: (x, y, self) => ContentProvider | null

Defined in: packages/react/src/generated/jsx.ts:9887

Emitted when a drag is about to be initiated.

It returns the GdkContentProvider to use for the drag that is about to start. The default handler for this signal returns the value of the DragSource.content property, so if you set up that property ahead of time, you don't need to connect to this signal.

Parameters

Parameter	Type
x	number
y	number
self	DragSource

Returns

ContentProvider | null

---

onSequenceStateChanged()?

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

Defined in: packages/react/src/generated/jsx.ts:10200

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

GtkGestureSingleProps.onSequenceStateChanged

---

onUpdate()?

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

Defined in: packages/react/src/generated/jsx.ts:10210

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

GtkGestureSingleProps.onUpdate

---

Defined in: packages/react/src/generated/jsx.ts:9888

Overrides
