QCandlestickSet is undefined C Qt5.15-CodePudding

I'm using Visual Studio 2019 Community x64, Qt version 5.15.2. I have the 'Charts' module installed and selected in Project -> Properties -> Qt Project Settings -> Qt Modules

My code:

#include <QCandlestickSet>

struct Bar
{
    double open, close, high, low;
    qint64 timestamp;

    Bar() : open(0.0), close(0.0), high(0.0), low(0.0), timestamp(0)
    {
    }

    QCandlestickSet * toCandle(void)
    {
        return new QCandlestickSet(this->open, this->high, this->low, this->close, this->timestamp);
    }
};

I am getting the error:

Severity Code Description Project File Line Suppression State Error (active) E0020 identifier "QCandlestickSet" is undefined ProjectName ..\Bar.h 27

Any help would be appreciated.

Thank you in advance.

CodePudding user response：

As mentioned in the comments by G.M., everything QtChart related is held within a namespace called QtCharts.

Doing any of the following will fix this issue:

using QtCharts::QCandlestickSet;

using namespace QtCharts;

QtCharts::QCandlestickSet * toCandle(void)
{
    return new QtCharts::QCandlestickSet(this->open, this->high, this->low, this->close, this->timestamp);
}

Although the namespace is not mentioned in the page relating to QCandlestickSet, it is mentioned on the QtCharts page
