Install The Mouse Event

Mouse events are signals came from qobject when the user send an event by mouse. Forex: click, move, press. vb. We can get many ways these events. The firs one is to override the

virtual bool eventFilter(QObject *object, QEvent *ev) override;

function. If we want the events to come this function, we must  call this


function before.

If you want to get mouse or other events from an other element, you can get it’s event by same way (element must be inherited from QObject)
