    Hi...
    Is there example or tutorial how to make our own event? May be using sendEvent() or other? Is it true?

    Thanks in advance

      Hi,
      look at this paper: http://doc.qt.digia.com/qq/qq11-events.html#customeventtypes

      also next articles should be usefull:

        Thanks for reply. The document said that
        Here's a code snippet that shows how to post a custom event:
        @
        const QEvent::Type MyEvent = (QEvent::Type)1234;

        ...
        
        QApplication::postEvent(obj, new QCustomEvent(MyEvent));
        

        @

        Actually, what is in "... ", and other help said that QCustomEvent is obsolete, is there any other alternatives?
        The application that I make is detected a click like QMouseClickEvent, but the movement of coordinate and clicked comes from (x,y) coordinates from other function not from a real mouse. Thank you in advance.

          What are you trying to do?

          I have the suspicion that you might be heading into the wrong direction. Custom events are rather common in other environments, but hardly ever used in Qt.

            I am trying to make an event. My event want to imitate a mouse click using a point that was detected or not (ON-OFF-ON) using a laser pointer. When a user pointing laser pointer spotlight and the spotlight entering an item then a user give ON-OFF-ON sequence, it means that "item-clicked".
            Is there any suggestion?

            Thanks in advance
