Detailed Description

Provides sets of methods to subscribe to various signals generated by SessionModel.

Automatically tracks the time of life of SessionModel. Unsubscribes from the model on own destruction.

Member Function Documentation

setOnAboutToRemoveItem()

void ModelListenerBase::setOnAboutToRemoveItem ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  client = {}  )

overridevirtual

Sets callback to be notified when the item is about to be removed.

The callback will be called with (SessionItem* parent, tagrow), where 'tagrow' denotes child position being removed.

Implements ModelView::ModelListenerInterface.

Definition at line 61 of file modellistenerbase.cpp.

    m_model->mapper()->setOnAboutToRemoveItem(f, this);
}

Here is the call graph for this function:

setOnDataChange()

void ModelListenerBase::setOnDataChange ( Callbacks::item_int_t  f, Callbacks::slot_t  client = {}  )

overridevirtual

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

The callback will be called with (SessionItem*, data_role).

Implements ModelView::ModelListenerInterface.

Here is the call graph for this function:

setOnItemInserted()

void ModelListenerBase::setOnItemInserted ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  client = {}  )

overridevirtual

Sets callback to be notified on item insert.

The callback will be called with (SessionItem* parent, tagrow), where 'tagrow' denotes inserted child position.

Implements ModelView::ModelListenerInterface.

setOnItemRemoved()

void ModelListenerBase::setOnItemRemoved ( Callbacks::item_tagrow_t  f, Callbacks::slot_t  client = {}  )

overridevirtual

Sets callback to be notified on item remove.

The callback will be called with (SessionItem* parent, tagrow), where 'tagrow' denotes child position before the removal.

Implements ModelView::ModelListenerInterface.
