possible to connect defined signals(available in Qt designer) to custom slots...?

[Holy Cheater]

speaking of signals and slots.... can i connect my custom signals of a different class to the custom slots of a different class...??

Yes, if these 2 classes are derived from QObject (or from something, which is based on QObject).

QObject::connect(<ptr to signaling class>, SIGNAL( someSignal() ), <ptr to slot class>, SLOT( someSlot() ) );
