+ * @brief An abstract base class for event handlers.

+ * The idea of an event handler is that it is created for a
+ * certain purpose, for example moving or resizing of a part.
+ * Once that action is finished, the handler will destroy
+ * itself.
+ *
+ * This design pattern helps you to keep your event filters
+ * and your mousePressEvent, mouseMoveEvent etc. methods clean.
