I Agree. Tim: can you provide access to a machine with gcc-4.4 to give this problem a hands-on try. If not, please try to get to a solution that keeps Html_get_attr2() const and that avoids C++ const_casts by declaring const char* locals. -- Cheers Jorge.-

Yes. It's concisely explained here: http://gcc.gnu.org/gcc-4.4/porting_to.html -- Cheers Jorge.-

Any discussion & suggestion is welcome Excellent! I couldn't look into it in detail yet, but it's great that you have some real code here so we can get a picture of how it could work in the future.

One thing I don't see immediately is why a_Html_get_attr() must be changed to return char* instead of const char*. I would prefer to fix the callers of a_Html_get_attr() instead. Could you please post the compiler errors you get with current tip? Cheers, Johannes

Oh well. It didn't work the first time I tried it because terminals are the one thing that I start from an fvwm menu, and my fvwm2rc has the colors specified using flags...

At the same time Xpdf > reacted to *background though. Hm, maybe you have xterm specific resources set somewhere in your system. I guess these would overwrite the wildcard ones. With "appres xterm" you can get all matching resources for "xterm". > > Sometimes dillo changed its colors after a "xrdb -merge ~/.Xdefaults". > Others a xserver restart was needed.

I strongly prefer to use the standard mechanism for theming on each platform. On X11 this is X resources. That way you can consistently theme all your applications (at least the well behaved ones) with just a few lines in a central file. Also I think it is a great advantage of X resources that they are stored server side. So even applictions that are running remotely will use the consistent set of colors. Nevertheless I agree that this theme code actually belongs in the fltk library. I can try to send a patch to the fltk list that reenables the currently commented out X resources code.

JavaScript support experiment

by stevegigijoe＠yahoo.com.tw

Hello all After I successful build and running dillo-2. I pay more attention on how JavaScript support on dillo. There are some discussion on mailing list and useful information. http://lists.auriga.wearlab.de/pipermail/dillo-dev/2008-October/005065.html http://lists.auriga.wearlab.de/pipermail/dillo-dev/2009-April/006280.html As dillo is fast and small footprint. Things like JavaScript should not be affect overall performence. What we need ? 1.JavaScript parse engine. I personally prefer SEE (simple ECMAScript Engine). Light weight and seems maintained 2.Document Object Model. We have to all objects and that's relate with engine and browser. An really huge task ... More important how to combine it into dillo ? hard code into or by DPI ? As I'm new to dillo, I don't know you guys interesting about this. So I decide to do an small experiment to implement JavaScript support with libSEE + Boehm-GC. Get patch here http://tw.myblog.yahoo.com/stevegigijoe/article?mid=145&prev=-1&next=138 ****** Modify configure.in to check libsee and gc DOM Supports document.write() document.getElementById() document.forms.length document.[form name].length document.[form name].method document.[form name].reset() document.[form name].[input name].value Input HTML scripts and *.js from url run onClick script before submit ****** Take it as an study case.
