Can you tell me a good code editor to develop GTK+ application (highlight syntax etc) for Ubuntu Linux. I use geyne editor, but I want some features, for instance, which is in VAssistsX (in Visual Studio for C++) or ReSharper for C#. May be use NetBeans? And may be install any plugins in geyne or gedit?
You might try Anjuta since it is the official Gnome IDE https://wiki.gnome.org/Apps/Anjuta
