NetBeans C++ tools does not have anything similar to Peek Definition View / Hover Code Preview / Open in another split. Consider competing C++ tools:
- Peek View is used in Visual Studio to preview definitions on the fly without switching tabs / windows and loosing the current context.
- Hover Code Preview is used in Eclipse CDT quite similarly.
- Open in another split from Qt Designer is not so convenient as previous features, nevertheless it is useful too. It helps to keep the current tab visible while observing definition under consideration in another tab.
NetBeans C++ tools do not provide anything like that thus reducing it's usability as compared to competing tools.
