How do I make TK windows sit there while I look at them? At the moment, I have code, based on http://julialang.org/blog/2013/05/graphical-user-interfaces-part2/ that flashes a window on the screen, but then the program finishes and the window disappears.
I could add a "while true", but I assume there's some Tk function I call that "takes over" until the user kills the window? Thanks, Andrew
