Understanding the mechanism of signals and slots | Qt 5 Blueprints.

It is always appropriate to connect a signal with no arguments to a slot with no arguments. In fact, it is the only way such a signal can be connected. QPushButton::clicked() and QAction::triggered() are two very, very common cases of such signals*, and connecting them to no-argument slots is the only way to handle those signals. Is For example, if a signal is connected to two or more slots, the slots are the Executed in sequence as written in code. Any subclass from QObject can thus define such signals and slots. Another example is to be created for this, the following signal-slot concept used (see Figure 2). Figure 2: Connect signals and slots. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop. Example.
