Quit application immediately
Message 1 in thread
Hello,
I have a modal dialog which call a function which may receive an exception:
QString DatabaseClient::queryOneValue( const QString& statement)
{
QString r;
try {
query( statement);
Row row = fetchRow();
if (row != 0) {
r = row [0];
}
} catch (const Exception& e) {
if (QMessageBox::critical( 0, "Database Error", e.what(), "Exit",
"Continue") == 0) {
QApplication::exit( 1);
}
}
return r;
}
The problem is that the application exits only after I closed the modal
dialog. Does anyone know how I can quit the application immediately?
Thanks
Message 2 in thread
Fust do exit(1) (The function call, not the QApplication method.

I think the modal dialog has an own eventloop that you first have to exit. By brute
force, use exit(3).
