QDevelop is a development environment entirely dedicated to Qt4.
QDevelop requires Qt4, gcc under Linux or MinGW under Windows, possibly gdb for programs debugging and ctags for code completion.
QDevelop is available in English, French, German, Dutch, Polish, Spanish, Chinese, Russian and Italian. If you want to translate in your language, please contact me.
QDevelop is not a Kdevelop like or reduced. It's an independent IDE dedicated to Qt and is totally independent of KDevelop. Less complete, but faster, light and especially multi-platforms. QDevelop and KDevelop have different code sources.
