How can I do mouse click event on graph using QChartView?

[sys1]

I created a QChartView on top of a grid layout to draw the graph.(
I referenced the Creator's sample code.)

When I click this graph, I want to display the mouse click position on the text label in the main window.

I inherited QChartView and created a ChartView class and defined the mousePressEvent() function, but the mouse click did not work.

Not sure what i am missing
It would be appreciated if you uploaded the example code that can be operated.

I'm using C++/Window/Visual Studio 2019/Qt 5.15.1

Thank you

I want to display the mouse click position

Don't know about your mousePressEvent(). But when you get it working you might be interested in https://stackoverflow.com/questions/44067831/get-mouse-coordinates-in-qchartviews-axis-system.

Thank you

But, The mouse press event itself doesn't seem to work.

So I want an example code with a mouse press event action.

Why not? What is happening? How did you implement it?
