Hi Michael,
please take a look at the message below, I posted it a while ago in
the Altera Forum (www.alteraforum.com).
I am using nano-X version 0.91, Fltk 2.0.0 and Freetype 2.3.5, which
came in bundled with my distribution (uClinux).
Mfg,
Ricardo.

Hello,
i want to change the font and the fontsize in my app but not even the
label or fonts-demo is working.
is there a known bug about this?
------------------------------------------------------------------------------------------------------------
It works. Try the following (modified) demo app. Name it hello.cpp:
Code:
------------------------------------------------------------------------------------------------------------
#include <fltk/Window.h>
#include <fltk/Widget.h>
#include <fltk/Font.h>
#include <fltk/run.h>
using namespace fltk;
int main(int argc, char **argv)
{
fltk::Font** FontsList;
int FontsCount = fltk::list_fonts(FontsList);
Window *window = new Window(300, 180);
window->begin();
Widget *box = new Widget(20, 40, 260, 100, "Hello, World!");
box->labelfont(FontsList[0]);
box->labelsize(36);
box->labeltype(SHADOW_LABEL);
window->end();
window->show(argc, argv);
return run();
}
------------------------------------------------------------------------------------------------------------
Compile it with:
------------------------------------------------------------------------------------------------------------
$ nios2-linux-uclibc-g++
-I/home/jars/nios2-linux/uClinux-dist/lib/fltk -c hello.cpp
$ nios2-linux-uclibc-g++ hello.o
/home/jars/nios2-linux/uClinux-dist/lib/fltk/lib/libfltk2.a
/home/jars/nios2-linux/uClinux-dist/staging/usr/lib/libX11.a
/home/jars/nios2-linux/uClinux-dist/user/microwin/src/lib/libnano-X.a
-lpthread -o hello
------------------------------------------------------------------------------------------------------------
Remember to change the paths above to reflect your own system. You can
have any font size by modifying the line:
box->labelsize(36);
Somethings to consider:
- I never got to compile the FLTK demo apps by simply selecting the
item in menuconfig; I think it's broken;
- in /usr/fonts/truetype you should have your ttf fonts and a fonts.dir file:
------------------------------------------------------------------------------------------------------------
/usr/fonts/truetype # ls
DejaVuLGCSans.ttf DejaVuLGCSansCondensed-Bold.ttf
dejavulgcsans.ttf dejavulgcsanscondensedbold.ttf
fonts.dir
/usr/fonts/truetype # cat fonts.dir
2
dejavulgcsanscondensedbold.ttf
-dejavu-DejaVuLGCSans-medium-r-bold--0-0-0-0-p-0-iso8859-1
dejavulgcsans.ttf -dejavu-DejaVuLGCSans-medium-r-normal--0-0-0-0-p-0-iso8859-1
/usr/fonts/truetype #
------------------------------------------------------------------------------------------------------------
Cheers,
Ricardo.
