wxPythonics using python?
is a fork of: https://bitbucket.org/cwt/boa-constructor
some cosmetic stuff on Linux, some widgets were too small
still plenty of crashing though.
note: the code editor is imperfect in that you must sometimes manually delete lines in py sourcecode, although you deleted an object via the GUI designer already. kinda sucks.
it is about 40 lines of fixes to get Boa running against wxPython v.4 "Phoenix".
Also the py2 ---> py3 conversion by cwt looks kinda OK, tho I did not really look into it very hard.
