ItemDataRole
Item data roles.
Stores pointer to the map layer itself.
bool allowEmptyLayer() const
Returns true if the model allows the empty layer ("not set") choice.
True if index corresponds to an additional (non map layer) item.
QStringList additionalItems() const
Return the list of additional (non map layer) items included at the end of the model.
The QgsMapLayerModel class is a model to display layers in widgets.
QMap< QString, Qt::CheckState > mLayersChecked
QList< QgsMapLayer * > mLayers
bool showCrs() const
Returns true if the model includes layer's CRS in the display role.
bool itemsCheckable() const
returns if the items can be checked or not
True if index corresponds to the empty (not set) value.
