I'm trying to bind to the selectionChanged event. My aim is to find out the value that was clicked in a graph (specifically the x axis value).
Binding to the first selectionChanged works -
QObject::connect(
graph,
static_cast<void (QCPAbstractPlottable::*)(bool)> (&QCPAbstractPlottable::selectionChanged),
[](bool selected)
{
cout << "this event DOES indeed fire"! << endl;
}
);
QObject::connect(
graph,
static_cast<void (QCPAbstractPlottable::*)(const QCPDataSelection&)> (&QCPAbstractPlottable::selectionChanged),
[](const QCPDataSelection &data)
{
cout << "this event does NOT" << endl;
}
);
but binding to the second, which has the data I need, does not. Compiles, runs, but clicking on it does nothing. Not binding to the first does not change anything.
Appreciate any advice here.
Many thanks.
