Hello,
Developing an app and having trouble quitting app. Not able to spot it from docs. I'm trying to do it like this:
BackgroundItem {
onClicked: Qt.quit()
Label {
text: "Quit"
}
}
But get following result:
[W] QQmlEnginePrivate::sendQuit:1687 - Signal QQmlEngine::quit() emitted, but no receivers connected to handle it.

check the connect part in main.cpp:
http://developer.nokia.com/community/wiki/CS001626_-_Closing_a_Qt_Quick_application_from_QML
But I wouldn't put a Quit button when most of my users would expect the os default swipe action, so unless you are writing a game or for any other reason you must disable swipe don't put a quit button.
Thank you about the link and the clarification about good app design (and take it into account during release). Though I have seen the link, it raises more questions than answers for me. Why is Quit is so hard/complex to implement. My main function has just one line: return SailfishApp::main(argc, argv); Cannot see where to insert proper QObject::connect() which should do the trick.

QGuiApplication* app = SailfishApp::application(argc, argv);
QQuickView* view = SailfishApp::createView();
view->setSource(SailfishApp::pathTo("qml/main.qml"));
view->show();
QObject::connect((QObject*)view->engine(), SIGNAL(quit()), app, SLOT(quit()));
return app->exec();
Sorry text renders strangely even with code tags, just put new line after each ';'
fasza2mobile ( 2014-03-01 16:17:04 +0300 )editThank you for showing step forward. I have already tried many variations of this code what I have found. When I try to run the code I get this:
[W] unknown:138 - file:///usr/lib/qt5/qml/Sailfish/Silica/Page.qml:138: ReferenceError: __silica_applicationwindow_instance is not defined
Caused by this:
view->setSource()
As a result I get WSOD.
Ragnar Kurm ( 2014-03-02 00:57:42 +0300 )editWhat argument did you give to "view->setSource()" ? I belive in your case it should be:
SailfishApp::pathTo("qml/[insertYourProjectnameHere].qml")
that file contains ApplicationWindow {}
I think you've put your first page there.
