[SailfishDevel] A welcome dialog and pageStack's operation in progress.

[Dmitriy Purgin]

Hi Martin,

I had the same issue while dealing with a similar problem where start
page was showing BusyIndicator while the application is loading. What
I did is connected to Component.onCompleted in ApplicationWindow,
start the initialization procedure and replace the page after
initialization is done:

// main.qml

ApplicationWindow
{
    Component.onCompleted: {
        pageStack.push(Qt.resolvedUrl("pages/Loader.qml"))
        myApp.initialize(); // call of an exposed C++ method
    }
}

// Loader.qml:

Page {
    BusyIndicator {
        running: myApp.initializing // Q_PROPERTY exposed in C++ class
    }
    onRunningChanged: {
        if (!running)
            pageStack.replace(Qt.resolvedUrl("FirstPage.qml"))
    }
}

I think you can add both of your pages in Component.onCompleted() of
the ApplicationWindow and switch between them in runtime.

Cheers
