Qt Creator is a full-featured cross-platform IDE for C++ programming (with or without the Qt libraries). Primarily intended for use with the Qt toolkit, but usable for general C/C++ development too.

Pros
Cons
Con No zooming when working with the included Qt-Designer
When having GUIs bigger then the small preview section in the Qt-Designer it is necessary to scroll vertically and horizontally, which disturbs a fluid work flow and makes it impossible to get a quick overview of the according GUI.

Flagged Pros + Cons
Pro Built-in Qt GUI editor
Allows for the creation of a window based UI in a graphical editor, no code required to build the UI.
Con Qt-focused
Qt Creator is focused on being an IDE for Qt, as a general purpose IDE it performs quite well, but there are areas which are lacking such as project file support (support for generic/CMake projects lags behind Qt projects).
