* Hookay, so, if you wanna extend the ToolTips that are displayed
* in the Profile Graph, there's one 'toolTip' widget already on it,
* you can just pass it to your Reimplementation of QGraphiscItem
* and do the following:
*
* EventItem::setController(ToolTipItem *c)
* {
* controller = c;
* }
*
* void EventItem::hoverEnterEvent(QGraphicsSceneHoverEvent* event)
* {
* controller->addToolTip(text, icon);
* }
*
* void EventItem::hoverLeaveEvent(QGraphicsSceneHoverEvent* event)
* {
* controller->removeToolTip(text);
* }
*
* Remember to removeToolTip when you don't want it to be displayed.
