该状态支持以下值:
| 常量 | 描述 |
|---|---|
EventPoint.Unknown | 未知状态;与 Qt.TouchPointUnknownState 相同 |
EventPoint.Stationary | 事件点未移动;与 Qt.TouchPointStationary 相同 |
EventPoint.Pressed | 触摸点或按钮被按下;与 Qt.TouchPointPressed 相同 |
EventPoint.Updated | 事件点已更新;与 Qt.TouchPointMoved 相同 |
EventPoint.Released | 触摸点或按钮已被释放;与 Qt.TouchPointReleased 相同 |
States 类型是QFlags<State> 的 typedef。它存储 State 值的“或”组合。另请参阅QEventPoint::States
TapHandler {
gesturePolicy: TapHandler.ReleaseWithinBounds // exclusive grab on press
onGrabChanged:
(transition, eventPoint) => {
switch (transition) {
case PointerDevice.GrabExclusive:
console.log("took exclusive grab of point", eventPoint.id,
"on", eventPoint.device.name)
break
case PointerDevice.UngrabExclusive:
console.log("gave up exclusive grab of point", eventPoint.id,
"on", eventPoint.device.name)
break
case PointerDevice.CancelGrabExclusive:
console.log("exclusive grab of point", eventPoint.id,
"on", eventPoint.device.name, "has been cancelled")
break
}
switch (eventPoint.state) {
case EventPoint.Pressed:
console.log("on press @", eventPoint.position);
break
case EventPoint.Updated:
console.log("on update @", eventPoint.position);
break
case EventPoint.Released:
console.log("on release @", eventPoint.position);
break
default:
console.log(eventPoint.position, "state", eventPoint.state)
break
}
}
