need help in detecting offline mode.

[waichun89]

I'm trying to implement some code that will, detect if the phone is in Offline Profile, then it will prompt the user some message telling him that he is in Offline Mode.

But i've tried a lot of methods and look through a lot of guides, what I searched is only some guide that will display my device's profile.

Below is the codes for the webview application i made. All i want is to detect the offline mode and display a message, then proceed to my html view. I've implemented the GetDeviceInfo.h file i get from some guide.
But yeah, it doesnt work

#include <QtGui>
#include <QtWebKit>
#include "qwebviewselectionsuppressor.h"
#include <QSystemDeviceInfo>
#include <QMessageBox>
#include "GetDeviceInfo.h"

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QSystemDeviceInfo* deviceInfo = new QSystemDeviceInfo();
QSystemDeviceInfo::Profile prof = deviceInfo->currentProfile();
if(prof == QSystemDeviceInfo::OfflineProfile){
QMessageBox msgBox;
msgBox.setText("Your device is currently in Offline Mode, please switch it to Normal Mode in order to proceed.");
msgBox.exec();
}
QWebView view;
QWebViewSelectionSuppressor suppressor(&view);
view.setWindowTitle("World Cup App");
view.load(QUrl("qrc:/html/widget.html"));
view.show();

return app.exec();
}

Here's the original code of this page before i implement the codes:

#include <QtGui>
#include <QtWebKit>
#include "qwebviewselectionsuppressor.h"

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWebView view;
QWebViewSelectionSuppressor suppressor(&view);
view.setWindowTitle("World Cup App");
view.load(QUrl("qrc:/html/widget.html"));
view.show();

return app.exec();
}

Can someone please teach me how to do it in a simple way? Thanks a lot for helping.

You can use libprofile and profile_get_profile() to get the current profile.

I need a way to detect offline mode too. Could you please provide a code sample how to do this?

Cheers

Oh, and one more thing. I would also need a way to make the "Exit Offline" dialog appear.

Thank you very much in advance

I've checked Qt Mobility and I cannot reproduce any kind of issues. I'm able to identify all profiles correctly

#include <QtGui>
#include <QSystemDeviceInfo>
#include <QSystemNetworkInfo>
using namespace QtMobility;

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

    QSystemDeviceInfo* deviceInfo = new QSystemDeviceInfo();
    QSystemDeviceInfo::Profile profile = deviceInfo->currentProfile();
    switch(profile) {
    case QSystemDeviceInfo::UnknownProfile:
        qDebug() << "Unknown";
        break;
    case QSystemDeviceInfo::SilentProfile:
        qDebug() << "Silent";
        break;
    case QSystemDeviceInfo::NormalProfile:
        qDebug() << "Normal";
        break;
    case QSystemDeviceInfo::LoudProfile:
        qDebug() << "Loud";
        break;
    case QSystemDeviceInfo::VibProfile:
        qDebug() << "Vib";
        break;
    case QSystemDeviceInfo::OfflineProfile:
        qDebug() << "Offline";
        break;
    case QSystemDeviceInfo::PowersaveProfile:
        qDebug() << "Powersave";
        break;
    case QSystemDeviceInfo::CustomProfile:
        qDebug() << "Custom";
        break;
    }
}

Are you sure you are not asking about network connection information?

Thank you very much for this code. However, I need something that works with Qt 4.6.3 and, if I'm not completely mistaken, Qt Mobility is not included with it. Is there a way to do it in 4.6.3?

Thanks

Qt Mobility will be merged in Qt in 4.7. For now it's a set of separate libraries, however, it doesn't change anything for a developer.

Oh, so does it mean that I can use Qt Mobility already now and it will work in all N900 with PR1.2? It's not beta or anything?

Mobility has reached 1.0.0 and 1.0.1 is almost done... but the latter has not been tagged yet.

Oh cool.

Anyway, I'm trying to use this:

   QSystemDeviceInfo* deviceInfo = new QSystemDeviceInfo();
        QSystemDeviceInfo::Profile profile = deviceInfo->currentProfile();
        if (profile == QSystemDeviceInfo::OfflineProfile) {
            updated = "The device is in Offline mode. Please exit Offline mode and try again.";
        } else {
            updated = "Connecting...";
        }

But I get the following error in Qt Creator:

undefined reference to 'QtMobility::QSystemDeviceInfo(QObject*)'
undefined reference to 'QtMobility::QSystemDeviceInfo::currentProfile()'

Am I doing something wrong?

Cheers

Did you add

CONFIG += mobility
MOBILITY += systeminfo

to a project file? Did you install libqtm-dev?

[Sasler]

CONFIG += mobility
MOBILITY += systeminfo

to a project file? Did you install libqtm-dev?

Ehr... nope, sorry.

But does the usage of libqtm-dev mean that it's not usable for public apps for N900?

[gnuton]

No. dev packages contain the header development files and tools.

[divanov]

I don't know what is public application and what could be opposite to that (private application?), but there is no problem with using libqtm-dev.

OK, let me rephrase my question. Can I use the it for an app that would be released in Extras or Ovi Store? If yes, do I need to add something to Debian control file, so that it will be able to install the necessary libs?

Thank you very much for your help
