State supports the following values:

常量	描述
`EventPoint.Unknown`	Unknown state; same as Qt.TouchPointUnknownState
`EventPoint.Stationary`	The event point did not move; same as Qt.TouchPointStationary
`EventPoint.Pressed`	The touch point or button is pressed; same as Qt.TouchPointPressed
`EventPoint.Updated`	The event point was updated; same as Qt.TouchPointMoved
`EventPoint.Released`	The touch point or button was released; same as Qt.TouchPointReleased

States 類型是 typedef 對於 QFlags<State> . It stores an OR combination of State values. See also QEventPoint::States

TapHandler {
    gesturePolicy: TapHandler.ReleaseWithinBounds // exclusive grab on press
