It might be a good idea to list the problems with tcl/tk so we can weigh them against the difficulty of using a different GUI toolkit. The problems I see are:
- difficult to implement a decent zoom function for a canvas
- can't display png without the Img library (included in 8.6)
- can't do alpha transparency
Of the three I listed, I'm mostly interested in the first as it means that (without prior planning) it's hard to take a patch you've been working on at font size 10 and display it adequately over a projector, for example. (If there's a work around I'd like to know it.)
I'd like to hear others, but I'm mostly interested in problems with tcl/tk >= 8.5 as the GUI.
- Because tcl/tk is an interpreted language it is a lot slower than a
compiled language: you have a script in ASCII that has to go through a processor that interprets the script to call a lower-level machine that actually does the work, while Qt is compiled so it does what you ask it directly, more or less.
- tcl/tk behaves differently on the three main platforms. See the
problems with font sizing for instance.
