Best practice for porting qml loader to pageStack

[Jon Heron]

Hello All,
I am porting my symbian qml apps to meego. In order to enable auto orientation it seems I need to use the pageStack element instead of the loader element I am currently using.
What I have currently is a listview in main.qml that loads all the qml modules (using the loader element) depending on whats selected from the list.
I am getting confused about how to initialize the main.qml as the initial page on the stack.
Should I be creating a new window that pushes main.qml onto the stack or should I be pushing the listview itself as the initial window from main.qml?
I know this is a basic question, I am just not "getting it"
Thanks for any insight or guidance!
Cheers,
Jon

You can call main.qml from project's main.cpp only :

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QmlApplicationViewer viewer;
    viewer.setOrientation(QmlApplicationViewer::ScreenOrientationAuto);
    viewer.setMainQmlFile(QLatin1String("qml/fff/main.qml"));
    viewer.showExpanded();

    return app.exec();
}

Create a pagestack in the main.qml & initialize from it the initial page of the application(in your case the listview):

Main.qml:

import QtQuick 1.1
import com.nokia.meego 1.0

PageStackWindow {
    id: appWindow

    initialPage: mainPage

    XYZListingPgae{                           /// XYZListingPage is the ListView qml
        id: mainPage
    }

Thanks
So I will need to move the content of the current main.qml, the listview, to a separate qml file that I push to the stack...
Got it!

OK, I have implemented the pagestack and it seems to be working fine, except for what I wanted it for! Now the orientation is locked in portrait and wont rotate automatically like expected.
Here is what I have in main.qml

import QtQuick 1.1
import com.nokia.meego 1.0

PageStackWindow {
    id:mwindow
    width: 1000
    height:1000
    initialPage: recMain
    
Rectangle
{
    id: recMain
  anchors.fill: parent
.....
}
}

Here is my main.cpp

#include <QtGui/QApplication>
#include "qmlapplicationviewer.h"
#include <QDeclarativeEngine>
#include <QDeclarativeContext>
#include <QSettings>
#include "settings.h"

Q_DECL_EXPORT int main(int argc, char *argv[])
{
    QScopedPointer<QApplication> app(createApplication(argc, argv));
    app->setOrganizationName("SnappyAppz");
    app->setOrganizationDomain("snappyappz.com");
    app->setApplicationName("E-Calc");
    Settings* settings = new Settings(app.data()); //for qsettings wrapper
    //set up settings file in corect path on the particular device
    QString str = app->applicationDirPath(); //returns path of app exe
    settings->setPath(QSettings::NativeFormat, QSettings::UserScope, str);
QScopedPointer<QmlApplicationViewer> viewer(QmlApplicationViewer::create());
    viewer->setOrientation(QmlApplicationViewer::ScreenOrientationAuto);
    viewer->rootContext()->setContextProperty("Settings", settings);
    viewer->setMainQmlFile(QLatin1String("qml/ec/main.qml"));
    viewer->showExpanded();
    return app->exec();
}

Anybody have any advice as to why it wont rotate automatically?
Cheers,

If you have below statement in your pro file, please remove and check
Avoid auto screen rotation
DEFINES += ORIENTATIONLOCK

[vineet.jain]

Also do check in device as well if you are not already doing so, as there have instances when the orientation issue exists only with meego emulator.

Thanks!
Yes it rotates fine on Qemu and over the RDA, its just on the sim that it wont rotate! Its all working now and the port is complete.
