QGraphicsItem::setToolTip does not work

[Nadia]

Hi,

I have an item dierived from QGraphicsItem.

and I want a toolTips for this item

hotPoint::hotPoint(const QPointF& hotPoint)
{
    setAcceptHoverEvents(true);
    setToolTip("An important value");
    point = hotPoint;
}

hotPoint::hotPoint(const QPointF& hotPoint)
{
    setAcceptHoverEvents(true);
    setToolTip("An important value");
    point = hotPoint;
}

To copy to clipboard, switch view to plain text mode 

what else I should do to make toolTip shown?

You might want to call the base class implementation of the constructor. Apart from that you need to define boundingRect() properly and add the item to the scene.

Hi,

Thanks for replay. I have added the item to scene and define boundingRect() properly but I found in docs that also need to set

setAttribute( Qt::WA_AlwaysShowToolTips)

setAttribute( Qt::WA_AlwaysShowToolTips)

To copy to clipboard, switch view to plain text mode 

Note that by default tooltips are only shown for widgets that are children of the active window. You can change this behavior by setting the attribute Qt::WA_AlwaysShowToolTips on the window, not on the widget with the tooltip.

I set this property to view and to main window cause I don't know who actually are active
