Constructor & Destructor Documentation

DistributionSelector()

DistributionSelector::DistributionSelector	(	std::optional< MeanConfig >	mean_config,
		GUI::ID::Distributions	distributions,
		QWidget *	parent,
		BeamDistributionItem *	item
	)

Parameters

mean_config

controls how the mean value is shown and can be input. If this parameter is nullopt then the mean value can not be input and only symmetric distributions are provided

Precondition

! mean_config && distributions == Distributions::Symmetric (i.e. the combination of all distributions without mean input is currently not supported)
