Insert QchartView into a QGraphicsView.

AuLoMa

Hi,
I created a QGraphicsView in QtDesigner, that I have called "chart" and promoted in QChartView :

I wanna give him a chart from my main function.. For that, I created a function in mainwindow:

void MainWindow::addChart(QChart * chart){
    this->centralWidget()->findChild<QChartView>("chart").setRenderHint(QPainter::Antialiasing);
    this->centralWidget()->findChild<QChartView>("chart").setChart(chart);
}

I call this function correctly in the main: :

MainWindow w;
QChart *chart = new QChart();
// ...
 w.addChart(chart);

However, the IDE accept it but when I start the compilation, this code dosen't compile. It returns errors like : no matching function for call to ‘QChartView(QObject*) dans qobject.h
or : could not convert ‘qt_qFindChild_helper(((const QObject*)this), (* & aName), QtCharts::QChartView::staticMetaObject, options)’ from ‘QObject*’ to ‘const QtCharts::QChartView&’

Is it a promotion error of the QGraphicsView ? Or maybe I should do something in the .pro file ? Or is there a more simple method to do that ?

Thank you for your help.

Hi
If you added the view in Design mode and promoted it, it should be accessible via
ui->chart.

So no need to find it again with findChild
