Description
Double-clicking QLineEdit under the touch screen does not select a word，Three mouse clicks do not select the line.
1.
if (!mouseMove && positionChanged) {
QWindowSystemInterfacePrivate::MouseEvent moveEvent(window, e->timestamp,
e->localPos, e->globalPos, e->buttons ^ button, e->modifiers, Qt::NoButton,
e->nonClientArea ? QEvent::NonClientAreaMouseMove : QEvent::MouseMove,
e->source, e->nonClientArea);
if (e->synthetic())
moveEvent.flags |= QWindowSystemInterfacePrivate::WindowSystemEvent::Synthetic;
qWarning()<< "positionChanged："<< moveEvent.device << e->device;
processMouseEvent(&moveEvent); // mouse move excluding state change
processMouseEvent(e); // the original mouse event
return;
}
Print the message when double-click under the touch screen(error1.mp4)：

}
}
Print the message when double-click under the touch screen(error2.mp4),*It is obvious that the problem is caused by a e->device->type() error,*Will cause mousePressButton to be updated to Qt:: noButton and cause DoubleClick to be false ：
