addToFitParameter()

void FitParameterHelper::addToFitParameter ( FitParameterContainerItem *  container, ParameterItem *  parameterItem, const QString &  fitParName  )

static

Adds given parameterItem to the existing fit parameter with display name fitParName.

If parameterItem is already linked with another fitParameter, it will be relinked

Definition at line 64 of file FitParameterHelper.cpp.

    ASSERT(container);
 
    removeFromFitParameters(container, parameterItem);
    for (auto fitPar : container->getItems(FitParameterContainerItem::T_FIT_PARAMETERS)) {
        if (fitPar->displayName() == fitParName) {
            SessionItem* link = fitPar->model()->insertNewItem("FitParameterLink", fitPar);
            link->setItemValue(FitParameterLinkItem::P_LINK, getParameterItemPath(parameterItem));
            break;
        }
    }

createFitParameter()

void FitParameterHelper::createFitParameter ( FitParameterContainerItem *  container, ParameterItem *  parameterItem  )

static

Creates fit parameter from given ParameterItem, sets starting value to the value of ParameterItem, copies link.

getFitParameterNames()

QStringList FitParameterHelper::getFitParameterNames ( FitParameterContainerItem *  container )

static

Returns list of fit parameter display names.

getParameterItem()

ParameterItem * FitParameterHelper::getParameterItem ( FitParameterContainerItem *  container, const QString &  link  )

static

Returns ParameterItem corresponding to given link.

Link is relative to ParameterContainerItem, so first we have to find it
