+ * @brief The user would connect to this signal to get a KeyEvent when KeyEvent is generated.
+ *
+ * If the control already consumed key event, KeyEventProcessor do not need to Emit keyEvent.
+ * Therefore, KeyinputManager first checks whether KeyEvent is generated as KeyEventGeneratedSignal.
+ * After that keyEventProcessor must invoke KeyEvent only if KeyEventGeneratedSignal () is not consumed.
+ *
+ * A callback of the following type may be connected:
+ * @code
+ * bool YourCallbackName(const KeyEvent& event);
+ * @endcode
+ *
+ * @return The return is true if KeyEvent is consumed, otherwise false.
