QInputDialog In Main

? Offline

the Following is my code

@#include <QtGui/QApplication>
#include <QInputDialog>
//#include "mydilog.h"
#include <QDebug>

int main(int argc,char* argv[])
{

QApplication app(argc, argv);
bool ok;
QString output;
  output = QInputDialog::getText(NULL, ("QInputDialog::getText()"),
                                              ("User name:"), QLineEdit::Normal,
                                               "test", &ok);
qDebug() << "Ok == " << ok;
qDebug() << "output == " << output;
app.exec&#40;&#41;;

}@

How can i Implement this

compare the output with "Text to Exit" and call exit() ?

I'm not quite sure what "... i want the app.exec() ..." means but if you want to enter the event loop before exiting (for whatever reason) use a singleshot timer.
@
int main(int argc,char* argv[])
{
...

qDebug() << "Ok == " << ok;
qDebug() << "output == " << output;

if(ok == true)
    QTimer::singleShot(0, &app, SLOT(quit()));

return app.exec();

}
@
Otherwise just don't call QApplication::exec().
@
int main(int argc,char* argv[])
{
...

qDebug() << "Ok == " << ok;
qDebug() << "output == " << output;

if(ok == false)
    return app.exec();

return 0;

}

QApplication::quit() and QApplication:exit() does nothing if there is no event loop running (ie. before QApplication::exec() is called).

for exit() i mean the stdlib function.
