Hi all, I intend to start coding the UI of the heap profiling toolkit I'm working on [1] soon. I'd be happy to get some advice on choosing the right windowing toolkit for this task. The main requirements are: - portability and native look & feel if possible - easy to distribute executables under Windows - relatively slow code rot - sane interface that doesn't need wild workarounds even if what I'm doing is not trivial or elementary - trouble-free source installation in case someone wants to contribute As I see, at the moment there's no serious alternative besides GTK and wx, so my question is which do you think is better suited to this task? I have absolutely no development experience with GTK, and while I used a bit of wx in the past (in C++), I'm not really familiar with it either, especially not the Haskell bindings. I noticed that installing the wx binding with user rights doesn't seem to work directly from hackage (doesn't pass --user to ghc-pkg?), but it looks like a problem that can be solved with some hand editing. I'm a bit more afraid of setting up a development environment under Windows; is there any major pain involved with either of these libraries if I use MinGW? And how about their interface? Is there any significant difference? I'd especially like to hear the opinion of someone who's reasonably familiar with both.
