Sorry to bother you again with this. I know this is been asked/answered before. I have searched (googled) and read a lot on this topic and tried each and every instructions (moc, Q_OBJECT macro etc..) to solve this error.
Finally i tried the mailing lists and found a solution: http://www.archivum.info/[email protected]/2010-02/00805/Re-%28Qt-interest%29-Runtime-Error--connect-No-such-slot-%28FIXED%29-But.html But still i am having the following runtime error.
