toggle QLineSeries visibility with QPushButton & connect?

[pauledd]

Hi
I just wonder how I can accomplish a toggle visibility of a bunch of QLineSeries with some QPushButton's. I have 2 QLineSeries and 2 QPushButtons. Then I wrote 2 public slot functions for each series/button and connected them to each other.

Is there a more elegant way like having only one toggle function that gets passed the series name as parameter? But how to connect then signal and slot?

I have now:

tabwidget.cpp:

TabWidget::TabWidget(QTabWidget *parent) :
    QTabWidget(parent)
{...
seriesPressure = new QtCharts::QLineSeries();
seriesTempIn = new QtCharts::QLineSeries();
...
pbTempIn = new QPushButton("Pressure",tab3);
pbTempIn->setCheckable(1);
pbTempIn->setChecked(1);
pbTempOut = new QPushButton("Temp In",tab3);
pbTempOut->setCheckable(1);
pbTempOut->setChecked(1);

connect(pbTempIn,&QPushButton::clicked,this,&TabWidget::toggleSeriesTempIn);
connect(pbTempOut,&QPushButton::clicked,this,&TabWidget::toggleSeriesTempOut);
...}

void TabWidget::toggleSeriesTempIn()
{
    if(pbTempIn->isChecked())
    {
        seriesTempIn->show();
    }
    else
        seriesTempIn->hide();
}
void TabWidget::toggleSeriesTempOut()
{
    if(pbTempIn->isChecked())
    {
        seriesTempIn->show();
    }
    else
        seriesTempIn->hide();
}

@pauledd hi, this should work just as well:

connect(pbTempIn,&QPushButton::toggled,seriesTempIn,&QLineSeries::setVisible);

great! That works. With that I can spare the toggle functions at all.
Thanks!
