QChartView mouse double click

[IknowQT]

I want to know how to double-click the mouse.
The last thing I want to do is double-click with gestures.

Why doesn't gesture support double-click?

Hi
You will override
https://doc.qt.io/qt-5/qwidget.html#mouseDoubleClickEvent

Do notice that double clicks are not real.
its 2 single clicks and Qt keep track of time between and location if makes you a double click event.

So if you override both mousePress and mouseDoubleClickEvent BOTH will be called by a double click.
This is by design and it's up to you to write logic to handle both if you need to have both single and double click actions.

  Well it does in QML
