QObject::startTimer: QTimer cannot have a negative interval

[wysota]

What is the datatype you are using to store your "60000 seconds" value? You are aware that 60000 seconds is not one minute, right? So are we talkig about seconds or miliseconds here? What datatypes are you using for those values?

[iswaryasenthilkumar]

am having one text file inside that
60000
10000
after reading this file i assigned to variables..and pass these variables to timeout ();
i want to display one images for first images for 60 seconds..and second image for 10 seconds.

after reading this file i assigned to variables

What variables? How did you do it? Show the code.

[iswaryasenthilkumar]

code:

#define configpath "/digital_images/config"
void Widget::readconfigfile()
{
    dir.cd(configpath);
    QFile file1;
    QString configfile="DI_config.txt";
    file1.setFileName(dir.absoluteFilePath(configfile));
    file1.open(QIODevice::ReadOnly);
    QTextStream stream(&file1);
    checkremoteseconds=stream.readLine().toInt();
    checklocalseconds=stream.readLine().toInt();
}

#define configpath "/digital_images/config"
void Widget::readconfigfile()
{
    dir.cd(configpath);
    QFile file1;
    QString configfile="DI_config.txt";
    file1.setFileName(dir.absoluteFilePath(configfile));
    file1.open(QIODevice::ReadOnly);
    QTextStream stream(&file1);
    checkremoteseconds=stream.readLine().toInt();
    checklocalseconds=stream.readLine().toInt();
}

this was my code sir

[wysota]

Is it really that hard to read what I write?

What is the datatype you are using to store your "60000 seconds" value?

[iswaryasenthilkumar]

sorry sir.
i used datatype as QString

[wysota]

No, you didn't.

Wysota is asking: What is the data type of the variables checkremoteseconds and checklocalseconds?

Since you don't bother to check if the configuration directory exists, the config file exists in the directory, or the file opens successfully I would add:
What is the actual value you get in those variables?
What is the value of those variables when you actually use them?

Why have you chosen to use QObject::startTimer() instead of QTimer?

[iswaryasenthilkumar]

i used qint16 for checkremoteseconds and checklocalseconds

[wysota]

The largest value qint16 can hold is 2^15-1 = 32767.

[iswaryasenthilkumar]

as yu said i did ..bt still i got same error
qint32 remoteseconds=60000
QObject::startTimer: QTimer cannot have a negative interval

Are you sure you are using the same variable and not locally shadowing the member/global variable you have elsewhere?
