nanogui: Thread: using fltk fonts system with nano

Im using FLTK 1.1.7 with nano-X 0.91. In nano-X ,i could load a new
font(*.pcf or *.fnt) dynamically using GrCreateFont() and show using
GrText().

I convert normally the ttftobdf and the bdftopcf and then load them in
nano-X.But how could I use the same fonts from FLTK ?

Could I use only the 255 system defined fonts,can I change them to use
the font I intentended to?

Hope someone could give some tips here,

Regards,
Kishore

I do not understand the question but I am using FLTK (X Windows) fonts
with nano-X with no problems.
I am also using FLTK 1.1.7 and nano-X 0.91 and libnx.

The FLTK uses X-Windows fonts (mostly Helvetica) and I just copied the
fonts to the directory where the nano-X can find them and let nano-X
load them.
I did not go thru any conversions. I just used the *.pcf.gz files
directly.

Please, clarify your question.
Martin

Hi
Thanks for the response!
My  nanoX configuration for pcf support look like this.

####################################################################
# PCF font support 
# Selecting HAVE_PCFGZ_SUPPORT will allow you to directly read
# .pcf.gz files, but it will add libz to the size of the server
####################################################################
HAVE_PCF_SUPPORT         = Y
HAVE_PCFGZ_SUPPORT       = N
PCF_FONT_DIR             = "fonts/pcf"


I dont use .pcf.gz files.will it function similarly if I add normal pcf
filed in the above defined directory? 

Although I put the files in defined directory,it shows only with default
fonts.

what am I  doing wrong here?

Regards,
Kishore

Check the current working directory of your applicaiton.

this might different that what you expect it to be

Hi,

which application u mean?  nano-X  Or  application ?

I have nano-x installed in /usr/bin.And the *.pcf fonts
at /usr/bin/fonts.

I start my application in this sequence

% cd /usr/bin
%./nano-X &
% /tmp/fltkexample

But it doesnt work?

Shall I compile nano-X fonts path configured to absoulte path instead of
relative path as in config file?

Kishore

the debug output look so

>XLoadFont('fixed') = '(null)' [0]

Its not able to find the 'fixed' font.

I would use a complete path in PCF_FONT_DIR like:
PCF_FONT_DIR = /usr/lib/X11/fonts/pcf
Then, this is where your font files need to be on your target.

Do you have a 'fixed.pcf' file in your /usr/lib/X11/fonts/pcf (in my
case) directory on your target?

If your fixed font has a different file name then you need the fonts.dir
file with the line like:
some_fixed_font_file.pcf fixed

You need to resolve directory and naming issues because your program
cannot find the fonts.

Also, you may add debugging messages to LoadFont.c and print 'fontdir',
'xfontname' and 'font' variables.
Then you will know everything. This is how I found my problems.

Hi,
I work on a embedded system so my fonts directory see a bit different.
I found a directory for fonts at  "/lib/fonts"

and it did have  "fontdir" with entries for 'fixed'

In fontdir file::

	fixed 5x7.bdf BDF n 50 70 
	fixed 6x13.bdf BDF n 50 120 
	micro micro.bdf BDF n 50 40 
	helvetica helvB08.bdf BDF n 75 80 
	helvetica helvB10.bdf BDF n 75 100 
	helvetica helvB12.bdf BDF n 75 120  ....


but these are only for the bdf files. I think I can just change bdf file
to pcf to make it work.Anyway ,I hope this tip would
help me move in the right direction.
Regards,
Kishore

I also work on embedded system and everything works from RAM disk but
the idea is still the same.
The font directory has to be located (match the configuration),
it needs to have the right font files and the font.dir file if names do
not match.
Then it will work.
I use pcf.gz and ttf fonts and after solving similar problems, it works
now.
