The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index.

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.

This tutorial will give you an in-depth The extra keywords are #defined away with the standard preprocessor. The keywords such as public, private are ignored for Qt slots. All slots are actually public and can be connected. Declaring slots as private means that you won't be able to reference them from context in which they are private, like any other method.

Well, slots are basically normal routines of your class, sicne you may use them also directly. Therefore, I would consider the private and public declaration as a matter of use and philosphy.
