Widget wrappers are used to create widgets for individual Processing parameters, and handle retrieving and setting the current value for those parameters. Widget wrappers can be created for different dialog types, allowing different appearance and behavior of widgets depending on whether they are being created for use in a standard algorithm dialog, a batch processing dialog, or a modeler dialog. Individual widget wrappers are not usually created directly, instead they are constructed through the central registry, via calls to QgsGui.processingGuiRegistry()->createParameterWidgetWrapper(). .. versionadded:: 3.4 %End %TypeHeaderCode #include "qgsprocessingwidgetwrapper.h" %End public: QgsAbstractProcessingParameterWidgetWrapper( const QgsProcessingParameterDefinition *parameter = 0, QgsProcessingGui::WidgetType type = QgsProcessingGui::Standard, QObject *parent /TransferThis/ = 0 ); %Docstring Constructor for QgsAbstractProcessingParameterWidgetWrapper, for the specified ``parameter`` definition and dialog ``type``. %End QgsProcessingGui::WidgetType type() const; %Docstring Returns the dialog type for which widgets and labels will be created by this wrapper. %End QWidget *createWrappedWidget( const QgsProcessingContext &context ) /Factory/; %Docstring Creates and return a new wrapped widget which allows customization of the parameter's value.

The caller takes ownership of the returned label. Some parameter type and dialog type combinations will return None for this method. If None is returned, then no label should be shown for the parameter's widget (i.e. the label is embedded inside the widget itself).
