More like this:
```c++
    if (m_pConfig->getValueString(ConfigKey("[Waveform]", "WaveformOverviewType"),
            "0").toInt() == 0 ) {
        overviewWidget = new WOverviewLMH(pSafeChannelStr, m_pConfig, m_pParent);
    } else {
        overviewWidget = new WOverviewHSV(pSafeChannelStr, m_pConfig, m_pParent);
    }
```
