Show tooltip under mouse cursor

lipposkiman

Hello all!!

I would like to show a tooltip exactly under the mouse cursor ( and i've done it), but it disappear immediately and it seems that is calling the leaveEvent of the widget that has created the tooltip.
It happen even if i don't move the mouse cursor.

Any suggestion please?

Many thanks

How about creating your own ToolTip and use its methods showText & hideText based on anything you want - mouse movement, timer.

Hi and welcome to devnet,

How are you doing your tooltip ?

Many thanks for your answers,
here the code used at the moment.

@class myview : public QTreeView {

bool viewportEvent(QEvent * event) {

if (event->type() == QEvent::ToolTip) {

QHelpEvent *helpEvent = static_cast<QHelpEvent *>(event);
QModelIndex index = indexAt(helpEvent->pos());

QRect r(visualRect(index));
QString tipText(index.data(0).toString());

if (r.width() >= fontMetrics().width(tipText)) {
event->ignore();
QToolTip::hideText();
return true;
}
else {

QPoint p = r.topLeft();

p -= QPoint(2,
#ifdef Q_WS_WIN
21
#else
16
#endif
);
event->accept();
QToolTip::showText(mapToGlobal(p), tipText);
return true;
}
}
return QTreeView::viewportEvent(event);
}

...

}@

Create my own tool tip class is not easy for me and take long time.
Maybe there is another way.

Thanks

What about handling the Qt::ToolTipRole in your model ?
