Unfortunately, I can't find any way to catch a signal of mouse click on any QLineSeries
at QChartView
. This is required for the subsequent increase in the thickness of the curve on the graph.
QChartView QLineSeries select by mouse click

You can use the clicked signal of the
QLineSeries
and since it will affect the same series then you could create a derived classmain.cpp
Update:
you have to connect the series, you do not understand that it is ui-> vchrt but assume that it is a QChartView, but QChartView does not have the clicked signal so it seems strange to me that this code works, on the other hand:
is a bad practice in C ++, you are using the C style in C ++, you should use container as QList , for example:
after that you must modify your slot, only the
QObject
s are passed the pointer,QPointF
must be passed by value, but even so it is not necessary since you will not use that data, and as the one that emits the signal is theQLineSeries
this is passed throughsender()
in the slot, with a casting we get the series and the changes are made.:*.h
*.cpp
