QTabWidget setCurrentIndex() problems

[Astrognome]

I've been having a mysterious problem with my QTabWidget.

This is not working.

ui->TabWidget->setCurrentIndex(settings.value("tab_index", 1));

ui->TabWidget->setCurrentIndex(settings.value("tab_index", 1));

To copy to clipboard, switch view to plain text mode 

It throws this error:

error: no matching function for call to 'QTabWidget::setCurrentIndex(QVariant)

error: no matching function for call to 'QTabWidget::setCurrentIndex(QVariant)

To copy to clipboard, switch view to plain text mode 

However, this code works:

settings.setValue("tab_index", ui->TabWidget->currentIndex());

settings.setValue("tab_index", ui->TabWidget->currentIndex());

To copy to clipboard, switch view to plain text mode
