Member Function Documentation

setOnAboutToRemoveItem()

virtual void ModelView::ItemListenerInterface::setOnAboutToRemoveItem ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  owner  )

pure virtual

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.

Implemented in ModelView::ItemMapper.

setOnChildPropertyChange()

virtual void ModelView::ItemListenerInterface::setOnChildPropertyChange ( Callbacks::item_str_t  f, Callbacks::slot_t  owner  )

pure virtual

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.

Implemented in ModelView::ItemMapper.

setOnDataChange()

virtual void ModelView::ItemListenerInterface::setOnDataChange ( Callbacks::item_int_t  f, Callbacks::slot_t  owner  )

pure virtual

Sets callback to be notified on item's data change.

Callback will be called with (SessionItem*, data_role).

Implemented in ModelView::ItemMapper.

setOnItemDestroy()

virtual void ModelView::ItemListenerInterface::setOnItemDestroy ( Callbacks::item_t  f, Callbacks::slot_t  owner  )

pure virtual

Implemented in ModelView::ItemMapper.

setOnItemInserted()

virtual void ModelView::ItemListenerInterface::setOnItemInserted ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  owner  )

pure virtual

Sets callback to be notified on child insertion.

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

Implemented in ModelView::ItemMapper.

setOnItemRemoved()

virtual void ModelView::ItemListenerInterface::setOnItemRemoved ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  owner  )

pure virtual

Sets callback to be notified on child removal.

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

Implemented in ModelView::ItemMapper.

setOnPropertyChange()

virtual void ModelView::ItemListenerInterface::setOnPropertyChange ( Callbacks::item_str_t  f, Callbacks::slot_t  owner  )

pure virtual

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

Callback will be called with (compound_item, property_name).

Implemented in ModelView::ItemMapper.

unsubscribe()

virtual void ModelView::ItemListenerInterface::unsubscribe ( Callbacks::slot_t  client )

pure virtual

Removes given client from all subscriptions.

Implemented in ModelView::ItemMapper.
