With the Qt signal and Qt slot concept, Qt takes a slightly different approach. This Concept has the advantage that Qt automatically disconnects if one of the communicating objects is destroyed.

1. Qt uses object-oriented memory management where objects are deleted automatically when their parent object is deleted. 2. Signals and slots provide a mechanism for communication between Qt objects using signals that are emitted by one object and caught by slot functions in other objects. 3. A signal mapper can be used to map multiple signals to a single slot so that different logic can be handled depending on which signal was emitted. - Download as a PDF or view online for free
