The component binds gesture objects of different **GestureType**s through gesture events. Each gesture object provides gesture-related information in the gesture response event. In the following example, the **TapGesture** object provides gesture-related information in the **onAction** event. For details about the event definitions of other gestures, see the corresponding gesture sections. To bind multiple gestures, use [combined gestures](ts-combined-gestures.md).
- TapGesture

| onAction((event?:GestureEvent) => void) | Callback invoked when a tap gesture is recognized.|

| -------- | -------- | -------- |
| repeat | boolean | Whether the event is triggered repeatedly. This attribute is used for the **LongPressGesture** event.|
| offsetX | number | Offset of the gesture event on the x-axis, in vp. This attribute is used for the **PanGesture** event. A positive value means panning from left to right, and a negative value means the opposite. |
| offsetY | number | Offset of the gesture event on the y-axis, in vp. This attribute is used for the **PanGesture** event. A positive value means panning from top to bottom, and a negative value means the opposite. |

| angle | number | Rotation angle for the **RotationGesture** event;<br>angle of the swipe gesture for the **SwipeGesture** event, that is, the change in the included angle between the line segment created by the two fingers and the horizontal direction.<br>**NOTE**<br>Angle calculation method: After a swipe gesture is recognized, a line connecting the two fingers is identified as the initial line. As the fingers swipe, the line between the fingers rotates. Based on the coordinates of the initial line's and current line's end points, an arc tangent function is used to calculate the respective included angle of the points relative to the horizontal direction by using the following formula: Rotation angle = arctan2(cy2-cy1,cx2-cx1) – arctan2(y2-y1,x2-x1) The initial line is used as the coordinate system. The clockwise rotation is 0 to 180 degrees, and the counter-clockwise rotation is –180 to 0 degrees.|
