On startup I want to make some security checks and, if they fail, display a message to the user and close the main window. Currently I make these checks in the QMainWindow constructor, but if I call the close method, nothing happens and the application conti...

Sorry for the dumb question, but I'm working with Qt and C++ for the first time, and working through the tutorial and some samples. One thing that was mentioned was that Qt stuff doesn't need to be explicitly deleted. So, main question, does this also apply to collections of Qt stuff?
