[Solved] Cannot include QSystemDeviceInfo

[A Former User]

@Vijay Ah that's even better then. I have not looked into using mobility directly in QML yet.

import Qt 4.7
import QtMobility.systeminfo 1.1

Rectangle{
....

DeviceInfo {
    id: deviceinfo;
    //        onBatteryStatusChanged : doBatteryStatusChange(status);
    onPowerStateChanged : getPowerState(/*powerState*/);
    onBatteryLevelChanged: doBatteryLevelChange(level)
    property int battlevel: batteryLevel;

    monitorBatteryLevelChanges: true
    monitorBatteryStatusChanges: true
    monitorPowerStateChanges: true
    monitorCurrentProfileChanges: true
    monitorBluetoothStateChanges: true
}
...

}

0k, but what about .cpp? why can not i include QSystemDeviceInfo.h?

[A Former User]

Have you tried:

@
#include <QSystemDeviceInfo>
@

ie without the ".h" suffix. Can you post the exact command line passed to the compiler and error msg please? That way we can see if it has the correct -I arguments or not.

[A Former User]

on .cpp:
error: QSystemDeviceInfo: No such file or directory
althought i am using windows 7 and Qt 4.7.3

And the command line passed to the compiler please? Which target are you trying to build for?

all right. perhaps it was because i wrote "mobility" instead of "MOBILITY" in CONFIG and did not write "symbian:TARGET.CAPABILITY = ReadDeviceData" in .pro file.
thank everybody!

[A Former User]

Yes the MOBILITY variable in the .pro file needs to be in uppercase. The missing symbian capabilities flag would have caused errors later on in the compilation (or maybe at runtime).

Glad to see you hav eit working now. Good luck with the rest of your project.

I am making a desktop app and not able to include QSystemDeviceInfo all the above steps i have tried but it dosnt work its giving error no such QSystemDeviceInfo file.i m using qt 4.7

[A Former User]

Did you try to reinstall qt?

[rishygupta]

ya i have tried in 3 system but it didnt worked i am compiling it by desktop compiler not Symbian or etc...

[A Former User]

What is the application output?

[rishygupta]

QSystemDeviceInfo: No such file or directory

[A Former User]

As for me with QMessage. But if I go to the folder that contains qmessage.h, the file stays there. What about you?

[rishygupta]

i am not able to even compile the code because of QSystemDeviceInfo: No such file or directory
as i have added below in pro file
symbian:TARGET.CAPABILITY = ReadDeviceData
CONFIG += mobility
MOBILITY += systeminfo

and trying to run in qt desktop mode of compiler

i will edit the title to continue this discussion.

that is it:
@
#include <QScrollArea>
#include <QDialog>
#include <QtSystemInfo/QSystemInfo>

#include <qmessage.h>

QTM_USE_NAMESPACE

PaginaPercheWortfluss::PaginaPercheWortfluss(QTabWidget *parent) :
QTabWidget(parent)
{
this->setAttribute(Qt::WA_LockLandscapeOrientation);

QWidget * widget1 = new QWidget;//informazioni
QVBoxLayout *layou = new QVBoxLayout(widget1);
QLabel *titolo1 = new QLabel(QString("<h2>Wortfluss: informazioni</h2>"));
