QML Window onClose event not working in some cases

drakebp

I am still new to qt/qml and having some issues with having my application stop on shutdown. This is to allow the user to save his work before he closes the app. At the moment I only see this on OS X, as its the only OS that creates a default menu item called (MyAppName). I am able to reproduce this issue with Qt 5.3 and Qt 5.4. There are a couple similar bugs listed in QTBUGS "#40093":https://bugreports.qt.io/browse/QTBUG-40093 but no one seems to have any work arounds or suggestions. I also see the same issue here with my onClosing not being recognized "#13347":https://bugreports.qt.io/browse/QTCREATORBUG-13347, which maybe related.

Code:
@
import QtQuick 2.0
import QtQuick.Window 2.2
import QtGraphicalEffects 1.0

Window {
id: splashWindow
objectName: "splashWindow"

visible: true
width: ( (Qt.platform.os == "ios" ) || (Qt.platform.os == "android") ) ? Screen.width : 1366
height: ( (Qt.platform.os == "ios" ) || (Qt.platform.os == "android") ) ? Screen.height : 768

Loader {
       id: myLoader
       width: parent.width
       height: parent.height
    }

Timer{
    id: loadingTimer
    interval: 1000
    running: false
    repeat: false
    onRunningChanged: {
        if(!loadingTimer.running){
            myLoader.source = "main.qml";
            mainContainer.visible = false;
        }
    }
}

Rectangle{
    id: mainContainer
    width: parent.width
    height: parent.height
    color: "transparent"
    state: "loading"

    Image{
        id: mainBackground
        source: "/svgs/headerbgparallax.png"
        width: parent.width
        height: parent.height
    }

    Image{
        id: mainLogo
        source: "/svgs/logo.svg"
        width: 328
        height: 159
        anchors.centerIn: parent

        MouseArea{
            id: ma
            anchors.fill: mainLogo
            onClicked: {
                myLoader.source = "main.qml";
                mainContainer.visible = false;
            }
        }
    }

    ZoomBlur {
        id: zb
        width: mainLogo.width
        height: mainLogo.height
        anchors.centerIn: mainLogo
        source: mainLogo
        samples: 24
        length: 0
        visible: false
    }
}

Component.onCompleted: {
    loadingTimer.start();
}

onClosing: {
    close.accepted = false;
    myLoader.item.saveOnShutdown();
}

}
@

onClosing

@close.accepted = false;@

works for users when they click the red X(window close), but if they go to the (MyAppName)->quit menu item it does not seem to handle the change to accepted. I even see the dialog show up but the app closes before the user can do anything. I do not create or alter any menu items for the application. If I am doing anything incorrectly glad to learn the right way and also any ideas for work arounds to this issue. Thanks!

Hi,

It definitely seems to be a bug. See "QTBUG-35390":https://bugreports.qt.io/browse/QTBUG-35390. There's a workaround mentioned in the last comment there.
