Constructor & Destructor Documentation

◆ QgsProcessingParameterDefinitionWidget()

QgsProcessingParameterDefinitionWidget::QgsProcessingParameterDefinitionWidget	(	const QString &	type,
		QgsProcessingContext &	context,
		const QgsProcessingParameterWidgetContext &	widgetContext,
		const QgsProcessingParameterDefinition *	definition = `nullptr`,
		const QgsProcessingAlgorithm *	algorithm = `nullptr`,
		QWidget *	parent = `nullptr`
	)

Constructor for QgsProcessingParameterDefinitionWidget, for a parameter of the specified type.

The context argument must specify a Processing context, which will be used by the widget to evaluate existing definition properties such as default values. Similarly, the widgetContext argument specifies the wider GUI context in which the widget will be used.

The optional definition argument may be used to provide a parameter definition to use to initially populate the widget's state.

Additionally, the optional algorithm parameter may be used to specify the algorithm or model associated with the parameter.
