Solved [QML] - Minimized window
-
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 -
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 objectLine 40 is : Application.state: {
I'm sorry but i'm very new in c++ / qml dev. Thanks for your help

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") } }

Ok thanks it works. I understand a better now.
Thanks
