Member Function Documentation

dummyFromIndex()

KisNodeDummy * KisModelIndexConverterShowAll::dummyFromIndex ( QModelIndex index )

overridevirtual

Returns the dummy associated with the index WARNING: index must be valid

Note

cannot return null

Implements KisModelIndexConverterBase.

Definition at line 34 of file kis_model_index_converter_show_all.cpp.

{
    Q_ASSERT(index.isValid());
    Q_ASSERT(index.internalPointer());
    return static_cast<KisNodeDummy*>(index.internalPointer());
}

dummyFromRow()

KisNodeDummy * KisModelIndexConverterShowAll::dummyFromRow ( int row, QModelIndex parent )

overridevirtual

Returns the dummy staying in the specified row of a parent May return null in case of inconsistency

Implements KisModelIndexConverterBase.

Definition at line 21 of file kis_model_index_converter_show_all.cpp.

{
    Q_ASSERT(parent.isValid() || !row);
 
    if(!parent.isValid()) return m_dummiesFacade->rootDummy();
 
    KisNodeDummy *parentDummy = dummyFromIndex(parent);
 
    int rowCount = parentDummy->childCount();
    int index = rowCount - row - 1;
    return parentDummy->at(index);
}

indexFromAddedDummy()

bool KisModelIndexConverterShowAll::indexFromAddedDummy ( KisNodeDummy * parentDummy, int index, const QString & newNodeMetaObjectType, QModelIndex & parentIndex, int & row )

overridevirtual

Calculates the parent and the position in the model for newly created dummy

Parameters

parentDummy	the dummy parent
index	the dummy index
newNodeMetaObjectType	is a class name of a newly added node This name is got from Qt's meta object system so you must compare this value against a corresponding staticMetaObject object only. We do not pass a pointer to a real node to limit the access to real nodes.
parentIndex	the parent index
row	the dummy row

Returns

whether the new dummy will be shown in the model

Implements KisModelIndexConverterBase.

Definition at line 56 of file kis_model_index_converter_show_all.cpp.

{
    Q_UNUSED(newNodeMetaObjectType);
 
    Q_ASSERT(parentDummy || !index);

        row = 0;
        parentIndex = QModelIndex();
    }
    else {
        int rowCount = parentDummy->childCount();

        parentIndex = indexFromDummy(parentDummy);
    }
    return true;
}

indexFromDummy()

QModelIndex KisModelIndexConverterShowAll::indexFromDummy ( KisNodeDummy * dummy )

overridevirtual

Returns the index corresponding to the position of the dummy in the model. Will return invalid index if the dummy should be hidden

Implements KisModelIndexConverterBase.

Definition at line 41 of file kis_model_index_converter_show_all.cpp.

{
    int row = 0;
 
    KisNodeDummy *parentDummy = dummy->parent();
 
    if(parentDummy) {
        int rowCount = parentDummy->childCount();
        int index = parentDummy->indexOf(dummy);
        row = rowCount - index - 1;
    }
 
    return m_model->createIndex(row, 0, (void*)dummy);
}

rowCount()

int KisModelIndexConverterShowAll::rowCount ( QModelIndex parent )

overridevirtual

Returns the number of children of the given index of the model

Implements KisModelIndexConverterBase.

{
    if(!parent.isValid()) return 1;
