Obtaining command line arguments in a QT application
- by morpheous
The following snippet is from a little app I wrote using the QT framework. The idea is that the app can be run in batch mode (i.e. called by a script) or can be run interactively.
It is important therefore, that I am able to parse command line arguments in order to know which mode in which to run etc.
[Edit]
I am debugging using QTCreator 1.3.1 on Ubuntu Karmic. The arguments are passed in the normal way (i.e. by adding them via the 'Project' settings in the QTCreator IDE).
When I run the app, it appears that the arguments are not being passed to the application. The code below, is a snippet of my main() function.
int main(int argc, char *argv[])
{
//Q_INIT_RESOURCE(application);
try {
QApplication the_app(argc, argv);
//trying to get the arguments into a list
QStringList cmdline_args = QCoreApplication::arguments();
// Code continues ...
}
catch (const MyCustomException &e) { return 1; }
return 0;
}
[Update]
I have identified the problem - for some reason, although argc is correct, the elements of argv are empty strings.
I put this little code snippet to print out the argv items - and was horrified to see that they were all empty.
for (int i=0; i< argc; i++){
std::string s(argv[i]); //required so I can see the damn variable in the debugger
std::cout << s << std::endl;
}
Does anyone know what on earth is going on (or a hammer)?
