Question

I’ve got a QT problem.
I want to make my program stop at place where I define, let`s say for 3 seconds. I couldn’t manage to do that. I need that because earler my program generates file and it is used by a program which I call a bit later. Problem is, that file doesn’t seem have enough time to create. My code looks like this:

void MainWindow::buttonHandler()
{
    QFile ..... (creating a text file);
    //Making a stream and writing something to a file
    //A place where program should pause for 3 seconds
    system("call another.exe"); //Calling another executable, which needs the created text file, but the file doesn`t seem to be created and fully written yet;
}

Thanks in advance.

Maybe you just need to close the written file before you call the other program:

QFile f;
...
f.close();

(This also flushes internal buffers so that they are written to disk)
