open source flow chart creator

I'm looking for an open source C++ / Qt flow chart creator, preferably on github,
that runs on windows, linux and osx.

What I have found, but not tested:

1888 Quick Flow Chart Creator is a very small and useful program which helps its users to create and draw flow charts in a quick and effective way. The program is able to create customized flow charts as it contains all the symbols which are required in the drawing process.
