The QgsMapLayerModel class is a model to display layers in widgets.
void setProject(QgsProject *project)
Sets the QgsProject from which map layers are shown.
@ EmptyRole
True if index corresponds to the empty (not set) value.
@ AdditionalRole
True if index corresponds to an additional (non map layer) item.
The QgsMapLayerProxyModel class provides an easy to use model to display the list of layers in widget...
QgsMapLayerProxyModel::Filters filters
static bool layerMatchesFilters(const QgsMapLayer *layer, const Filters &filters)
Returns if the layer matches the given filters.
QgsMapLayerProxyModel * setFilters(QgsMapLayerProxyModel::Filters filters)
Sets filter flags which affect how layers are filtered within the model.
void setExceptedLayerIds(const QStringList &ids)
Sets a blocklist of layers (by layer ID) to exclude from the model.
bool lessThan(const QModelIndex &left, const QModelIndex &right) const override
void setFilterString(const QString &filter)
Sets a filter string, such that only layers with names matching the specified string will be shown.
bool filterAcceptsRow(int source_row, const QModelIndex &source_parent) const override
QgsMapLayerProxyModel(QObject *parent=nullptr)
QgsMapLayerProxModel creates a proxy model with a QgsMapLayerModel as source model.
bool acceptsLayer(QgsMapLayer *layer) const
Returns true if the proxy model accepts the specified map layer.
QStringList exceptedLayerIds
void setExcludedProviders(const QStringList &providers)
Sets a blocklist of data providers which should be excluded from the model.
void setLayerAllowlist(const QList< QgsMapLayer * > &layers)
Sets an allowlist of layers to include within the model.
@ AnnotationLayer
QgsAnnotationLayer.
@ VectorTileLayer
QgsVectorTileLayer.
@ PointCloudLayer

Q_DECL_DEPRECATED void setLayerWhitelist(const QList< QgsMapLayer * > &layers)
Sets an allowlist of layers to include within the model.
void setExceptedLayerList(const QList< QgsMapLayer * > &exceptList)
Sets a blocklist of layers to exclude from the model.
Base class for all map layer types.
QString providerType() const
Returns the provider type (provider key) for this layer.
bool readOnly() const
Returns if this layer is read only.
virtual Q_INVOKABLE QgsDataProvider * dataProvider()
