Detailed Description

This class serves as an index into an AbstractItemModel.

It can only be generated from the model and internally either contains a void pointer or a integer which must be used to point at the item referenced.

◆ getData()

Variant ml::ModelIndex::getData ( int attributeIndex) const

convenience method, this calls model()->getData(this, attributeIndex);

◆ isValid()

bool ml::ModelIndex::isValid ( ) const
inline

return if this index is valid i.e. it points at an item in the model

Definition at line 55 of file mlAbstractItemModel.h.

◆ model()

AbstractItemModel * ml::ModelIndex::model ( ) const
inline

get the model of this index (this will be NULL for invalid indices)

◆ operator!=()

bool ml::ModelIndex::operator!= ( const ModelIndex & index) const

◆ operator=()

const ModelIndex & ml::ModelIndex::operator= ( const ModelIndex & index)

explicit assignment operator (handles reference counting if necessary)

◆ operator==()

bool ml::ModelIndex::operator== ( const ModelIndex & index) const

◆ userID()

size_t ml::ModelIndex::userID ( ) const
