After reading some tutorials I came to the conclusion that one should always use pointers for objects. But I have also seen a few exceptions while reading some QT tutorials (http://zetcode.com/gui/qt4/painting/) where QPaint object is created on the stack. So now I am confused. When should I use pointers?
If you don’t know when you should use pointers just don’t use them.
It will become apparent when you need to use them, every situation is different. It is not easy to sum up concisely when they should be used. Do not get into the habit of ‘always using pointers for objects’, that is certainly bad advice.
