From the FLTK devs: [dejan.lekic@gmail.com: Re: [fltk.development] This year GSOC]
by onepoint＠starurchin.org March 8, 2008

March 8, 2008

Just to make sure no-one misses this, some love from the FLTK guys! Jeremy Henty ----- Forwarded message from Dejan Lekic <dejan.lekic(a)gmail.com> ----- From: Dejan Lekic <dejan.lekic(a)gmail.com> To: fltk-dev(a)easysw.com Subject: Re: [fltk.development] This year GSOC Date: Thu, 28 Feb 2008 08:25:55 -0800 Personally, the thing I most anticipate and would like to see improved, which is related to FLTK, is the Dillo port to FLTK2. Seriously, if Dillo2 could be done as a library, and provide a Group widget which is directly embeddable into any FLTK2 application, that would be IMHO a huuuuuge thing. So, I hope someone would help Dillo guys either via GSoC, or other way(s). More information: http://www.dillo.org . Get the fresh FLTK2 port of Dillo from CVS: :pserver:anonymous@auriga.wearlab.de:/sfhome/cvs/dillo Kind regards _______________________________________________ fltk-dev mailing list fltk-dev(a)easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev ----- End forwarded message -----

patch: form data character encoding
by place＠gobigwest.com March 6, 2008

March 6, 2008

It seems to be working well. For example, you can go to www.google.gr and paste in ????????. Instead of 2530 hits of gibberish, you now get 57,400,000 of Greek. I ran it through various tests, but of course it'll get better testing from those of you who routinely use ?'s and ?'s and so on. It's an annoyance that fltk won't allow normal X character composing. I don't want to learn their special rules, so I have to paste anything non-ascii from an xterm.

[patch] simplify Region::addRectangle ()
by Johannes.Hofmann＠gmx.de March 6, 2008

March 6, 2008

Hi, the patch below simplifies Region::addRectangle () quite a bit. It now simply tries to minimize the sum of the areas of all rectangles in the Region while still covering all rectangles that have been added with addRectangle (). For example if we have Thereby the total area that is actually redrawn is reduced and the code gets much simpler. However it may now happen that small parts of the screen are drawn that were not requested to be drawn. This patch does not reduce any flickering.

patch: choose charset for form submission
by place＠gobigwest.com March 4, 2008

March 4, 2008

It picks a charset, but doesn't actually do any translation. I have to decide whether to distort the charset decoder to handle encoding. It's nice to have all of the iconv stuff in one place, but it's not nice to have something that's shaped to decode dbufs reused for just any purpose...
