virtual | ~QgsSubsetStringEditorProvider () |
virtual bool | canHandleLayer (QgsVectorLayer *layer) const =0 |
Returns true if the provider can handle the layer. | |
virtual bool | canHandleLayerStorageType (QgsVectorLayer *layer) const |
Returns true if the provider can handle specifically the layer->provider()->storageType() This method will only be called if canHandleLayer() returned true. | |
virtual QgsSubsetStringEditorInterface * | createDialog (QgsVectorLayer *layer, QWidget *parent=nullptr, Qt::WindowFlags fl=QgsGuiUtils::ModalDialogFlags)=0 |
Creates a new dialog to edit the subset string of the provided layer. | |
virtual QString | name () const |
Subset string editor provider name, this is useful to retrieve a particular subset string editor in case the provider has more than one, it should be unique among all providers. | |
virtual QString | providerKey () const =0 |
Provider key. | |

Returns true if the provider can handle specifically the layer->provider()->storageType() This method will only be called if canHandleLayer() returned true.
Typically a generic SQL provider for the OGR provider will return false, whereas a dedicated plugin with a specific behavior for a OGR driver will return true.

Creates a new dialog to edit the subset string of the provided layer.
It may return nullptr if it cannot handle the layer. The returned object must be destroyed by the caller. On successful accept(), the QgsSubsetStringEditorInterface implementation is responsible for setting the updated string on layer.
