Does someone meet the same question?

I thought that was you on the fltk newsgroups. The same question was posed there.

You are correct, FLTK 1.1.x does not work with anything but single byte characters. There is a patched version that does support UTF-8, if that would be helpful for you: www.oksid.ch/fltk-utf/

So it appears that font will not work with 1.1.x. IIRC this was going to be addressed for 2.0. I can't say anything for the patched version the link will take you to. Perhaps it would be worth the hassle.

you say 1.1.x didn't surpport chinese. and 2.0 will ?
I download the fltk-utf8 patch,but it also can't work.
if the problem can't be solved,I must choose another GUI
I have study it for a long time. I don't want to give up it!

Part of the problem I have is that I use the standard fonts and unless a program installs its own special font I never mess with them. Maybe you can teach me a thing or two here. What exactly is utf8 for and how does it relate with the fonts? Are there fonts you can use (to display chinese characters) that are not of this extended type? You are correct, 1.1.x does not have utf8 support and 2.0 is supposed to have it.

Like I said, I just don't know the answers so if you could shed some light on it for me perhaps I could be more helpful.

What was the problem? Were you not able to get fltk to build? I looked at the site quickly after seeing the link at fltk.org. When I get some time I'll take a closer look and see if I can't help you out there. I have a hard time sitting at the keyboard after a long workdays in the heat though.

Yikes! That sounds really bad.

Don't give up just yet. The only thing I have found to be a headache with fltk is the amount of time it takes to go from being able to put together a decent UI, to the time it takes to have a good handle on how fltk does things. The library is large enough that you have no choice but to crawl in and learn what seems to be a c++ dialect. I would hate to see you have to throw that time away. Are you using 1.1.x for any reason other than the stability of it? You could always shift over to 2.0 unless but it really is not as stable and will be undergoing large changes for the next few years most likely. It seems to be designed to be The FLTK at some point. Many of the good solid 1.1.x ideas and working code is being moved to 2.0 code in the library itself. That tells me everything you like about 1.1.x will eventually be part of 2.0. Just not today.

I guess I will have to do a little reading on utf8 and how it would relate to a chinese font.

Good Luck, sorry I can't be more helpful just yet.

I had installed the fltk-utf8, but it also can't show chinese characters.
when intall it ,I get some warning like:
lcUniConv/big5.h:4103: warning: `big5_wctomb' defined but not used
lcUniConv/gb2312.h:2518: warning: `gb2312_wctomb' defined but not used
lcUniConv/jisx0201.h:30: warning: `jisx0201_wctomb' defined but not used
lcUniConv/jisx0208.h:2360: warning: `jisx0208_wctomb' defined but not used
lcUniConv/jisx0212.h:2135: warning: `jisx0212_wctomb' defined but not used
lcUniConv/ksc5601.h:2966: warning: `ksc5601_wctomb' defined but not used

You are so kindly. Thank you very much.
I graduate form university last year. And now I am in a IT company.
I like programming. But somtimes I have no enough confidence to work well

谢谢！

FLTK-UTF8 can display chinese.
But you must use UTF-8 encoded text and set the good font.
see the test program test/utf8.cxx

Yes,it can display chinese.Thank you very much!

And I have another question.How to open XIM?
This is my program:

CPP / C++ / C Code:

#include<FL/Fl.H>
#include<FL/Fl_Window.H>
#include<stdio.h>
#include<X11/Xlib.h>
#include<X11/Xlocale.h>

 int main(int argc, char ** argv)
{
   Display *display;
   XIM fl_xim=NULL;
   if(XOpenIM(display,NULL,NULL,NULL)==NULL)
       printf("XIM Open failed\n");

       Fl_Window *window = new Fl_Window(500,500,"test");
       Fl_Button *button = new Fl_Button(300,30,250,30);
       new Fl_Button(300,100,50,30,"abc");

   window->end();
   window->show(argc,argv);
   return Fl::run();
}

The program should show "XIM open failed",because I didn't open XIM on X-Widnow.But it didn't show "XIM open failed".

You don't need to do anything.
All the XIM things are handled by FLTK-UTF8.

You just need to start your XIM server and set the environmental variables in your shell.
(i.e . : export LANG=zh_TW; export XMODIFIERS="@im=xcin-zh_CN")
Then start your FLTK-UTF8 program.

If you want to know how I've made it, you can take a look at src/Fl_x.cxx

why it is very slowly?
when I run my program with chinese ,the window display first, then the chinese character display.If the font is biger,it will take more time to display.
