application never quits

[harmodrew]

hello! I'm writing the following application:

main.cpp:



#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QInputDialog>

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

MainWindow w;

QInputDialog id;
bool ans1, ans2;
int i1 = id.getInt(&w, w.tr("Title"), w.tr("Text"),0,0,20,1,&ans1));
int i2 = id.getInt(&w, w.tr("Title"), w.tr("Text"),0,0,20,1,&ans2));

if (ans1 && ans2)
{
w.showMaximized();
}
else
{
w.close();
}

return a.exec();

}


If I chose "OK" for both the first input dialog and the second one then the program continues rightly and clicking the classic "X" it exits correctly.
While if I chose "Cancel" in one of the input dialogs the window doesn't show (and I want it) but the application doesn't quit at all. It remains running in RAM.
I found this behaviour by debugging the program putting a breakpoint at the row "return a.exec();". This instruction never stop (so the program loops in the exec() function). what can it be?

thanks

it runs because it is not stopped by e.g. closing the last window. but you can simply avoid it by writing
return 0; in your else brace.

thanks, it worked :)
