[Solved] Cannot include QSystemDeviceInfo

ZapB

They are listed. See this "quickstart guide":http://doc.qt.nokia.com/qtmobility-1.2/quickstart.html for mobility.

@spode What do you mean? You can still use C++ in a QtQuick project. If you wan tto display it you just need to bind to the respective properties and possibly expose the info you need as properties if they are not already available.

ZapB

@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?

ZapB

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.

spode

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

ZapB

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!

ZapB

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.

spode

thank you! :)

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

spode

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...

spode

What is the application output?

rishygupta

QSystemDeviceInfo: No such file or directory

spode

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

spode

i will edit the title to continue this discussion.

spode

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

#include <qmessage.h>
