Using button

with observer logic of ZFObject, it's easy to listen on button click event

zfobj<ZFUIButtonBasic> button;
 
// declare button click listener
ZFLISTENER(onClickListener) {
    zfLog() << zfargs.sender() << " clicked";
} ZFLISTENER_END()
 
// add as observer
button->observerAdd(ZFUIButton::EventButtonOnClick(), onClickListener);
