problem I see with your solution is that the App could take
long time to launch, when there are a bunch of Pages that have
to be initialized at launch (depending on the structure of the
Pages).<br>
</div>
<div style="" class=""> <br>
So I would prefer lazy loading Pages, which will be
initialized when it is needed.<br>

<div style="" class=""> Hi Markus<br style="" class=""

<br style="" class="" clear="none">
In my app I chose to instantiate all my Pages in the
same place. Each of the pages has a declaration in a
separate qml file (e.g. MainPage.qml,
AreaSelectionPage.qml).<br style="" class=""
clear="none">
<br style="" class="" clear="none">
With this architecture none of the declarations need
to know about the previous or next page. It is not
their concern. Instead they emit signals NextPage,
BackPageWithInfo, and Cancelled. In the signal
handler in the page instantation I do the actual
pushing and popping, and because all pages are
instantiated in the same scope, they are all
available to be pushed / popped to. (see code
example below).<br style="" class="" clear="none">
<br style="" class="" clear="none">
The downside is that all the pages are created on
startup (regardless of if they are ever visited).
For lightweight pages this is not a problem, but for
some pages this might be a problem. For these I
dynamically create the page content when the page is
visible.<br style="" class="" clear="none">
