Subject: Re: Fruit basket program in Boo
No, I don't think that I am good enough to be able to write a good
wrapper
for WX.
I see that the guys that work for WXPerl or Win32::GUI have worked for
years
to make those wrappers, so it is not something very simple, while
learning a
new language is more simple.
But my problem is not that I find that it is hard to learn a new
language.
My problem with learning new languages is that I dislike an important
part
of each language.
For example I've tried to learn Java and SWT, but I've seen that SWT is a
lower level GUI library than Win Forms, and it doesn't have so many
controls
available as Win Forms.
Win Forms is pretty nice, it works very well with C#, but the problem
that
C# is Windows centric. I make almost all my programs to run on a web
server,
and all the web servers I use in productions are under Linux.
Mono could be accessible under Linux, but I don't know if asp.net also
works
fine under a Linux web server, and I don't like the PHP style, so I might
not like the asp.net style also.
If someone needs to create programs only for the web or only for the
desktop, it is much easy to choose, but if somebody needs to create both,
at
least one of the solutions would be not the best possible.
(Maybe that's why asp.net has an increasing success)
