MenuBar touch problem

miguelorenes

I have a really easy application based on QtQuick 2:

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    menuBar: MenuBar {
            Menu {
                title: qsTr("File")
                MenuItem {
                    text: qsTr("&Open")
                    onTriggered: console.log("Open action triggered");
                }
                MenuItem {
                    text: qsTr("Exit")
                    onTriggered: Qt.quit();
                }
                onAboutToHide: console.log("onAboutToHide");
                onAboutToShow: console.log("onAboutToShow");
            }
        }
}

When I use the mouse, all is working with no issues. But when I try in a touch screen, I am not able to show the menu bar and I can see in the Application Log:

QML debugging is enabled. Only use this in a safe environment.
qml: onAboutToShow
qml: onAboutToHide
qml: onAboutToShow
qml: onAboutToHide
qml: onAboutToShow
qml: onAboutToHide
qml: onAboutToShow
qml: onAboutToHide

It is very strange as look like impossible to use a QML MenuBar in a touch screen.

EDIT:
QT version: Qt5.7.1
OS: WIndows

I modified to application to be executed in QT5.4

import QtQuick 2.2
import QtQuick.Window 2.2
import QtQuick.Controls 1.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    menuBar: MenuBar {
            Menu {
                title: qsTr("File")
                MenuItem {
                    text: qsTr("&Open")
                    onTriggered: console.log("Open action triggered");
                }
                MenuItem {
                    text: qsTr("Exit")
                    onTriggered: Qt.quit();
                }
            }
        }
}

And the issue dissapear.
But If I execute with Qt5.7.1 kit, it is failing.
