setHiddenDataItemProviderKeyFilter(self, hiddenItemsFilter: Iterable[str])¶

Sets a filter to hide data items based on QgsDataItem.providerKey() associated with the item.

By default browser model shows all items from all available data item providers and few special items (e.g. Favorites). To customize the behavior, set the filter to not load certain data items. The items that are not based on data item providers have prefix “special:”, for example “special:Favorites”, “special:Home”, “PostGIS”, “MSSQL”

All items created by the providers listed in filter are hidden from the layer tree. This filter is always evaluated.

Parameters:: hiddenItemsFilter (Iterable[str]) – a list of data provider prefixes that will be hidden.

New in version 3.12.

setLayerType(self, type: Qgis.LayerType)¶

Sets the layer type to filter the model by. This is only used if filterByLayerType() is True.

setFilterByLayerType()

Parameters:: type (Qgis.LayerType) –

setShowLayers(self, showLayers: bool)¶

Sets show layers to showLayers

See also

showLayers()

New in version 3.14.

Parameters:: showLayers (bool) –

setShownDataItemProviderKeyFilter(self, shownItemsFilter: Iterable[str])¶

Sets a filter to show data items based on QgsDataItem.providerKey() associated with the item.

By default browser model shows all items from all available data item providers and few special items (e.g. Favorites). To customize the behavior, set the filter to load only certain data items. The items that are not based on data item providers have prefix “special:”, for example “special:Favorites”, “special:Home”, “PostGIS”, “MSSQL”

Only the items created by the providers listed in filter are shown in the layer tree. This filter is always evaluated.

Parameters:: shownItemsFilter (Iterable[str]) – a list of data provider prefixes that will be hidden.

New in version 3.14.

showLayers(self) → bool¶

Returns True if layers must be shown, this flag is True by default.
