Tooltip fall asleep delay for QGraphicsItem

Lachrymology

Hi all,

the current behaviour for Qt 5.11.2 when moving the mouse cursor over a QGraphicsItem with a tooltip is, that the tooltip is only shown for some seconds.

I want to remove this "fall asleep" behaviour. The tooltip should hide itself like on a normal QLabel, when the mouse leaves the object.

I tried to solve it over the setStyle method for the QGraphicsScene:

class MyStyle : public QProxyStyle
{
public:
    int styleHint(StyleHint hint, const QStyleOption *option = nullptr, const QWidget *widget = nullptr, QStyleHintReturn *returnData = nullptr) const override {
        if (hint == SH_ToolTip_FallAsleepDelay)
            return -1; //0 and 30000 doesn't work either
        return QProxyStyle::styleHint(hint, option, widget, returnData);
    }
};

I tried to override the helpEvent of QGraphicsScene to show the tooltips on my own, but the tooltip event is forwarded to the internal "tooltip-show-method" before the helpEvent is called.

Does anyone have another idea how to prevent the fall asleep behaviour?

I had an own implementation of showing the Tooltips in hoverEnter .. now I'm using the default tooltip method and this one works like expected.
