Sometimes when inheritance is problematic, one can replace it, or a part of it, with composition. That's the approach needed in Qt 4: instead of deriving from a QObject, derive from a non-QObject class (MyObjectShared) that carries a helper QObject that is used as a proxy to connect the signal to its slot; the helper forwards that call to the non-QObject class. Template class not supported by Q_OBJECT | Qt Forum Ok, having base class with non template signal-slot functionality and to derive a template class from it, will work fine for me. but, just for knowledge, what if i need to have signal-slot with template type.???

Deeper. Widgets emit signals when events occur. For example, a button will emit a clicked signal when it is clicked. A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop

It saves you to create a slot in your class which simply is emitting a signal. the text in the signal & slot explanatory part below the graph and shortly before the heading Signals is You can connect as many signals as you want to a single slot, and a signal can be connected to as many slots as you need.
