Multiple inheritance problem

[Mohsin]

I have created a ChartView class that inherits "QChartView" and "QObject".

I need to generate a SIGNAL from the ChartView class and connect to the MainWindow SLOT.

However, currently, I am getting the following error.

"direct base 'QObject' is inaccessible due to ambiguity"

class ChartView : public QChartView , public QObject
{
    Q_OBJECT
private:
 
}

class ChartView : public QChartView , public QObject
{
    Q_OBJECT
private:

}

To copy to clipboard, switch view to plain text mode 

If I don't add QObject, then SIGNAL and SLOT don't work.

Any suggestion?
