qradiobutton

whenever button switched on or off emits toggled() signal. connect signal if want trigger action each time button changes state. use ischecked() see if particular button selected.

you can write wrapper on qradiobuttons can connect toggled(bool) signals single slot toggled(int) of wrapper using i.e. qsignalmapper. can manage logic in such wrapper:

void radiohelper::initialize( const std::vector<                                    qsharedpointer<radiohelperentry> >& entries) {     entries_ = entries;     mapper_.reset(new qsignalmapper(this));     entriesiterator = entries_.begin();      int = 0;     while ( it!=entries_.end())     {        connect(( *it)->button_, signal( toggled(bool)), mapper_.data(),                                                                     slot(map()));        mapper_->setmapping( ( *it)->button_, (int)( *it)->mode_);        it++;        i++;     }     connect( mapper_.data(), signal( mapped(int)), this, signal( toggled(int)));     connect( this, signal( toggled(int)), this, slot( updatevalue(int))); }  void radiohelper::updatevalue( int v) {     value_ = v;     emit valuechanged(); }
