These lines seem to be too long as well, easiest copy+pasteable fix is probably to rewrite all of this as
```cpp
if (loading)
	return;

generalChanged = true;
ui->buttonBox->button(QDialogButtonBox::Apply)->setEnabled(true);
```
or maybe add a helper in window-basic-settings.hpp along the lines of
```cpp
inline void EnableApply(bool enabled)
{
	ui->buttonBox->button(QDialogButtonBox::Apply)->setEnabled(enabled);
}
```
