For necessary manipulations on unsubscription.

Sets callback to be notified when row is about to be removed.

Callback will be called with (compound_item, tagrow). For MultiLayer containing the T_LAYERS tag, the signal will be triggered on layer deletion with (multilayer*, {T_LAYER, row}) as callback parameters.

setOnChildPropertyChange()

void ModelView::ItemListenerBase::setOnChildPropertyChange ( Callbacks::item_str_t  f )

inherited

Sets callback to be notified on item's children property change.

Callback will be called with (compound_item, property_name). For MultiLayer containing the layer with "thickness" property, the signal will be triggered on thickness change using (layeritem*, "thickness") as callback parameters.
