[SOLVED] Process not exiting
-
Hello, I am trying to make a program to rename some files but after the renaming is done the program does not exit. Please help me.
Here is the code:
@#include <QApplication>
#include <QFileDialog>
#include <QDir>
#include <iostream>
#include <QDebug>class Tester : public QWidget
{
public:
void openDir()
{
QString dirstring = QFileDialog::getExistingDirectory(this,tr("Select a Directory"),QDir::currentPath());
QDir dir (dirstring);
dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
// dir.setSorting(QDir::Size | QDir::Reversed);
QFileInfoList list = dir.entryInfoList();
for (int i = 0; i < list.size(); ++i) {
QFileInfo fInfo = list.at(i);
QString fPath = fInfo.absoluteFilePath();
QFile file (fPath);
QString fPathwhitoutfilename = fInfo.absolutePath();
qDebug() << fPath;
QString cc = QString::number(i);
file.rename(fPathwhitoutfilename+"/"+cc+".jpg");
QApplication::quit();
}
}
};int main(int argc, char *argv[])
{
QApplication app(argc, argv);
Tester t;
t.openDir();
return app.exec();
}

You call QApplication::quit() in the loop. So if it would work your app would exit after first file is processed.
It does not exit, because you call QApplication::quit() before application enters the main event loop. The main event loop starts with app.exec().
I would suggest to delete QApplication::quit() line in openDir() and don't call app.exec() at return. Just return 0.
