Detailed Description

The following example prints debug statement everytime the current value of the slider is changed: void print() { qDebug() << "signal called"; } ... QSlider slider(Qt::Horizontal); ctkCallback callback(print); QObject::connect(&slider, SIGNAL(valueChanged(int)), &callback, SLOT(invoke())); ... The following example prints the new value of the slider void print(void* data){ qDebug() << reinterpret_cast<QSlider*>(data)->value(); } QSlider slider(Qt::Horizontal); ctkCallback callback(print); callback.setData(&slider); QObject::connect(&slider, SIGNAL(valueChanged(int)), &callback, SLOT(invoke()));
