I want to implement an exit button in my application, which has the following setup: I have a main function which looks like this:
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
I also have a mainWindow function which has been generated by the QT Creator IDE.
I design the GUI with the Qt Designer and when I want a pushbutton to do something when clicked, I use a function like this:
void on_selection_clicked();
I hope the setup is now sufficiently described.
Now to my problem: I want to implement a button, which, when clicked, terminates the window and the application. I first tried implementing this in a function like this:
void on_exit_clicked();
But I don't know that to to here.
Then I heard of a aproach via QObject::connect, but I have two questions:
1.) Where should I put this? In the main function?
2.) can I access the object simply via the object name given in the QT Designer?
