Thread: QObject::connect: No such slot !?!

  1. #1

    Default QObject::connect: No such slot !?!

    Hey all, Ive created a menuBar for my widget, but i have this strange error with all items on menubar...

    heres my code that creates the about item for the menubar.

    Qt Code:
    1. QPopupMenu *help = new QPopupMenu( this );
    2. help->insertItem( aboutIco, "About", this, SLOT(aboutMenuAction()));
    To copy to clipboard, switch view to plain text mode 

    in my .h file ive included under public slots section
    "virtual void aboutMenuAction();"

    but when i build the project the output says

    Qt Code:
    1. QObject::connect: No such slot SlackpackWidget::aboutMenuAction()
    To copy to clipboard, switch view to plain text mode 

    duh.. this is strange!
    can anyone plz help me?

    have you
    * added Q_OBJECT to the class declaration?
    * is the header listed in the HEADERS section of your .pro file?
