QTapAndHoldGesture::~QTapAndHoldGesture()
Destructor.
[static] void QTapAndHoldGesture::setTimeout(int msecs)
Set the timeout, in milliseconds, before the gesture triggers.
The recognizer will detect a touch down and if msecs later the touch is still down, it will trigger the QTapAndHoldGesture. The default value is 700 milliseconds.
参见 timeout().
