TouchPointPressed without previous release event QQuickEventPoint(valid:true accepted:false state:Pressed scenePos:QPointF(164.333,152.333) id:2000002 timeHeld:0)
现象：多个可点击区域，多次点击切换后，有个别地方点击没反应（如应用中，底部导航栏分为5个页签，快速点击各个页签，数遍后有一个或两个页签点着就没反应了，无法再切换页面）
修改方法：
C:\Qt\Qt5.9.4\5.9.4\Src\qtdeclarative\src\quick\items\
qquickevents.cpp
修改
QQuickPointerEvent* QQuickPointerTouchEvent::reset(QEvent*event)函数中内容
修改后为：
bool b = false;
for (int i = 0; i < newPointCount; ++i) {
auto point = m_touchPoints.at(i);
point->reset(tps.at(i), ev->timestamp());
if (point->state() == QQuickEventPoint::Pressed) {
if (grabbers.at(i)){
qWarning() << "TouchPointPressed without previous release event" << point;
b = true;
}
point->setGrabber(nullptr);
} else {
point->setGrabber(grabbers.at(i));
}
}
m_pointCount = newPointCount;
if (b){
emit qGuiApp->applicationStateChanged(Qt::ApplicationInactive);
emit qGuiApp->applicationStateChanged(Qt::ApplicationActive);
}
return this;
