Detailed Description

The base class for converting objects to/from QModelIndex used in KisNodeModel and KisNodeDummy used in KisDummiesFacadeBase (KisShapeController).

This is not a trivial task, because the indexing of nodes is reversed in KisNodeModel.

Member Function Documentation

dummyFromIndex()

virtual KisNodeDummy * KisModelIndexConverterBase::dummyFromIndex ( QModelIndex index )

pure virtual

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

Note

cannot return null

Implemented in KisModelIndexConverter, and KisModelIndexConverterShowAll.

dummyFromRow()

virtual KisNodeDummy * KisModelIndexConverterBase::dummyFromRow ( int row, QModelIndex parent )

pure virtual

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

Implemented in KisModelIndexConverter, and KisModelIndexConverterShowAll.

indexFromAddedDummy()

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

pure virtual

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

Implemented in KisModelIndexConverter, and KisModelIndexConverterShowAll.

indexFromDummy()

virtual QModelIndex KisModelIndexConverterBase::indexFromDummy ( KisNodeDummy * dummy )

pure virtual

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

Implemented in KisModelIndexConverter, and KisModelIndexConverterShowAll.

rowCount()

virtual int KisModelIndexConverterBase::rowCount ( QModelIndex parent )

pure virtual

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

Implemented in KisModelIndexConverter, and KisModelIndexConverterShowAll.
