GUI WINDOWS app to Mac

[bostero22]

Hello there, i know QT is cross-platform... but I have a question.. can you make a GUI for windows and once you are done change it so it can be run from a MAC? or you have to create it different from the beggining for it to run on a MAC??

thank you!

Code once, compile twice (once for win, once for mac), run on both.
Or in other words, you build two programs (one for windows, one for mac) from the same source code
