rsync (Everyone seems to like -z, but it is much slower for me)
Some notes on embedding Root's (https://root.cern/) TCanvas into wxWidgets window, mostly based on this post. Should also work for other GUI frameworks I suppose.
Seems straightforward, but I've struggled for a while to get it working, so I've decided to leave this note here for myself and others in need, as a starting point.
If you need to embed root, my first advice would be... don't. Obviously Root is a standard tool in physics, and I also use it extensively, but it is also a huge and convoluted C++ code, including it in your own app might cause trouble and crashes.
