[QML] - Minimized window

[csgib]

Hi,
For learning qml i try to write a simple game on my linux machine, i test it on android and my problem is exatly :

I have a soundtrack in my game and a timer. When i minimize my window i want to stop the audio track and timer, but i don't find a method for my ApplicationWindow to discover if the window is hidden or not.

Any help appreciate and sorry for my english ;-)

Thanks

Stéphane

Hi @csgib
Have a look at the property 'Qt.application.state' as described here:
http://doc.qt.io/qt-5/qml-qtqml-qt.html#application-prop

[csgib]

Ok but i don't understand where / how place the event capture of application.state ... If i understand it's just a property not a event signal, no ?

Thanks

Stéphane

@csgib
read about QML's property bindings.
This way you can use them like signals.

Sorry but i don't understand something, i made this :
ApplicationWindow {
Application.state: {
if (Application.state == Qt.ApplicationHidden)
{
console.log("I M MINIMIZED")
}
}
}

But when i compile i have this error :
QQmlApplicationEngine failed to load component
qrc:/main.qml:40 Non-existent attached object

Line 40 is : Application.state: {

I'm sorry but i'm very new in c++ / qml dev. Thanks for your help

@csgib
try this:

Connections {
    target: Qt.application
    onStateChanged:
        if(Qt.application.state == Qt.ApplicationActive) {
            console.log("ACTIVE")
        }
        else if(Qt.application.state == Qt.ApplicationSuspended) {
             console.log("ISUSPENDED")
        }
}
