first application batteryindiacator giving error :(

[rohan.i.ghosh]

Hello All,
I am a first time user and getting the following errors...
first its saying for the QSystemDeviceInfo *deviceInfo; --- >
syntax error:missing ';' before *

i have pasted all my project file, header and source file...I have followed their instruction exactly but things not working.....help needed..can anyone help????

=============================================================




#ifndef BATTERYIND_H
#define BATTERYIND_H

#include <QSystemInfo>
#include <QDialog>

namespace Ui {
class batteryind;
}

class batteryind : public QDialog
{
Q_OBJECT


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

private:
Ui::batteryind *ui;
void setupGeneral();
QSystemDeviceInfo *deviceInfo;
};

#endif // BATTERYIND_H

#include "batteryind.h"

{
ui->setupUi(this);
setupGeneral();
}

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

void batteryind::setupGeneral()
{
deviceInfo = new QSystemDeviceInfo(this);

ui->batteryLevelBar->setValue(deviceInfo->batteryLevel());

connect(deviceInfo, SIGNAL(batteryLevelChanged(int)),
ui->batteryLevelBar, SLOT(setValue(int)));
}

You should write:

QSystemDeviceInfo* deviceInfo;

in place of

QSystemDeviceInfo *deviceInfo;

Then tell me the result.

You should write:

QSystemDeviceInfo* deviceInfo;

in place of

QSystemDeviceInfo *deviceInfo;

Then tell me the result.

I think the declaration should works in any of the manner stated by you. It is not the soure of the error.


BTW try to use QTM_USE_NAMESPACE into your batteryind.h file.

One more thing, If it doesn't help than try to run some mobility examples that are come with Qt for checking if your Qt mobility is configured properlyy or not.

You should write:

QSystemDeviceInfo* deviceInfo;

in place of

QSystemDeviceInfo *deviceInfo;

Then tell me the result.

The two are identical. You could just as correctly write the line with no spaces at all.

[danhicksbyron]

What it's saying, in its own obscure fashion, is that "QSystemDeviceInfo" isn't recognized as a type/class name. (If not a type/class then it must be a variable, and the compiler's having a conniption figuring out what a variable name is doing in that location.)

In this case, the problem is that all Mobility interfaces are declared in the QtMobility namespace. Ie, the full name of the class is QtMobility::QSystemDeviceInfo. By including the QTM_USE_NAMESPACE macro call ahead (physically in the file) of any mention of a Mobility class name, however, you "imply" the namespace, sort of like doing an "import" in Java, so that you don't need to explicitly spell out the namespace in every use.

Thanks all for your help...james your trick worked...thanks for ur time..all of ull!!

I tried the examples they worked flawlessly, however, in case of this batteryindicator project I am still on danger level :P with plenty of errors starting with the one mentioned below. QT_USE_NAMESPACE is in batteryindicator.h and

class BatteryIndicator : public QDialog
{
Q_OBJECT

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

private:
Ui::BatteryIndicator *ui;
void setupGeneral();
QSystemDeviceInfo* deviceInfo; <- This is where I get this error batteryindicator.h:26: error: C2143: syntax error : missing ';' before '*'

};
