I have a class that is defined as below:

// Constructor
CustomPlot::CustomPlot(QWidget *parent) : QCustomPlot(parent)
    // Enable interaction
    setInteractions(QCP::iRangeDrag | QCP::iRangeZoom);

My question is, Is there a way to enable the drag using the middle/scroll mouse button instead of the left mouse button?" I could not find it in the documentation and I would appreciate your help.
I tried coding the drag functions myself and assign it to the middle button but it is not as smooth as the original mechanism.

Thank you.
