How to handle mousehover event on a label?

[Lykurg]

Reimp the handlers QWidget::enterEvent() and QWidget::leaveEvent(). Open and close the pop up there.

Thanks for your advice.
I tried, have no lucky.
Can you post the codes up if possible?
Thanks again.

what have you tried so far and how does your code look like?

You should make a new class inheriting from QLabel class.
In the new class, put the declaration of Widget events under the "signals:".
Then, connect the signals to your slots.
For example:

class myClass : public QLabel
...
signals:
void mouseReleaseEvent(QMouseEvent *);
...
public slots:
void mySlot();

in the constructor:
connect(this, SIGNAL(mouseReleaseEvent(QMouseEvent*)), this, SLOT(mySlot()));

That is totally wrong. You have to overload the mouseReleaseEvent. Not connect it to a slot.
