QT Creator - QT Mobility issues

[stewarth01]

Hi

I downloaded the latest Nokia SDK for QT yesterday - so latest version QT 4.7 etc.

I'm trying to use the mobility features - for example contacts, which work fine when targeting the Symbian Simulator.

However, when changing the target to Symbian Device I'm getting IDE warnings:
For example:
#include "QContactManager"

I get a pop up "No Such file or Directory".

Additionally, the code completing doesn't work for any QContact* classes etc.

( Like I said, all is well when targeting the simulator , no IDE warnings, code completion works as expected ).

Any ideas - thanks!

Have you tried ready examples available in the Qt wiki page.
Try that.

In fact, You have to add contcts API in your .pro file.
as below :

CONFIG += mobility
MOBILITY = contacts

Best regards,

Check what Rahul proposes and additionally it should be system include

#include <QContactManager>

In case it doesn't work make a file search in NokiaQtSDK for QContactManager file. You should have three of them, one for every target.

Hello,

My first try with Qt Mobility from the Nokia Qt SDK 1.0.2 is not successful. My .pro file is here:

#-------------------------------------------------
#
# Project created by QtCreator 2010-11-29T17:40:24
#
#-------------------------------------------------

QT       += core gui

TARGET = QMobilityTest
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

CONFIG += mobility
MOBILITY += contacts systeminfo

symbian {
    TARGET.UID3 = 0xe59a64c5
    TARGET.CAPABILITY += ReadUserData WriteUserData LocalServices NetworkServices UserEnvironment Location ReadDeviceData
    TARGET.EPOCSTACKSIZE = 0x14000
    TARGET.EPOCHEAPSIZE = 0x020000 0x800000
}

I work with Qt Creator. The code builds well. It runs well on Maemo and Qt Simulator. But when I try to make target debugging on a N97, the debugger tells me that it can't install from the package C:\Data\QMobilityTest.sis, due to General OS-related error. I have already installed the SIS file of Qt Mobility of the SDK.

What could be the problem?

[teknikko]

How you installed sis files to your phone? Via bluetooth ?
If yes, then you need to install appTRK on your phone.

After that put your phone USB Connection mode to "PC Suite mode"
and then start appTRK with USB mode. Bluetooth mode is not
working.

[teknikko]

From Windows start menu :

USB and appTrk works well with other projects. I installed Qt Mobility with the SIS of the SDK. I reinstalled it with the Symbian menu.

Here are my codes:

main.cpp:

#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
#if defined(Q_WS_S60)
    w.showMaximized();
#else
    w.show();
#endif

    return a.exec();
}

mainwindow.h:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
    class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H

mainwindow.cpp:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QContactManager>
#include <QSystemInfo>
#include <QContact>
#include <QList>

QTM_USE_NAMESPACE

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QContactManager cm;
    QList<QContact> allContacts = cm.contacts();
    QString strContactNumber;
    strContactNumber.setNum(allContacts.length());
    ui->iLabelContactNumber->setText(strContactNumber);

    QSystemInfo s;
    ui->iLabelCountryCode->setText(s.currentCountryCode());
}

MainWindow::~MainWindow()
{
    delete ui;
}

[teknikko]

OK. Here was some thread about 2 weeks ago concerning "contacts".
Qt Contacs "class" has invalid type on release libraries.

Try to find that discussion.

[teknikko]

Try this thread :

http://discussion.forum.nokia.com/fo...er-CNTMODEL-15

[bounlith.sirivong]

You are right, teknikko.

I comment all codes using Qt Contacts, keeping only QSystemInfo API. I reboot the phone, and the program is launched well by Qt creator.

Then I uncomment Qt Contacts codes. Curiously, now, the debugger does not complain about the installation of the SIS, but it stops at the launch of the app (the UI is not yet displayed), and can't go further. I click on the "Continue F5" button, but the debugger stops immediately. The problem seems to be Qt Contacts class.

Presently, my aim is only to know how to start using Qt Mobility. Not yet to develop a software. I know now how to set the .pro file and that QTM_USE_NAMESPACE is needed to use Qt Mobility classes.

Thanks.

I am facing exactly same problem...any luck?

Search for QContactManager file in SDK directory and provide a result.

[chetanpan]

I found QContactManager at following locations:

c:\nokiaqtsdk\simulator\qtmobility\mingw\include\qtcontacts
c:\nokiaqtsdk\symbian\sdk\epoc32\include\applications

Search for QContactManager file in SDK directory and provide a result.

This is strange as there should be three: Maemo, Symbian and Qt Simulator. I guess there is something wrong with SDK installation. You may try to reinstall it with offline installer.

[chetanpan]

Nothing is wrong as I did not install maemo by doing custom installation.
Update: But I think your suggestion is fine - as I could not find any other solution. I will reinstall with offline installer.
