Quitting a QT app

[Aztral]

I have a class, call it server, which inherits from QTcpServer.

My main looks like this:


int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
new server();

return app.exec()
}

My question is, since server inherits from QTcpServer, how can I get app.exec() to return thus properly calling the destructor for server(). Right now I'm not sure how I can get into the server() destructor and also exit the main QT event loop so that the program will quit.

I can properly delete the server() class with deleteLater() or a few other ways, but doing so doesn't terminate the program, I think because I'm still in the main event loop.

Thanks a lot.

Hi, why don't you just create your server object on the stack?

server myServerObject;

Sorry I got busy with a different problem and forgot to get back here!

Anyways, when I do that I get a rather large error:

*** glibc detected *** ./exename: free(): invalid pointer: 0xbf88ed6c ***

As I understand it this means I'm trying to delete something I didn't new. I simply cannot find where this might be happening. I have commented out every delete in my code and still the error occurs.

It has to be happening in my deleteLater() call that I call when I want the program to exit, but I'm not sure why that would be happening either.

Like Ginsengelf said, try creating it on the stack, and don't call delete or deleteLater on the server object in that case.

Then how do I get out of the main loop? Right now I can only exit the program via Control-C. Doesn't main have to return for objects on the stack to be removed (since it's being put on the stack in main)? I'm never reaching that return statement because I'm in a QCoreApplication.exec() loop that I'm never exiting. I guess my question is how do I get out of that loop nicely.
