|
|
* 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.
