Greg,
I changed my fonts.alias file to this:
!-*-helvetica-medium-r-normal--* -misc-dejavu_sans-medium-r-normal--0-0-0-0-p-0-ascii-0
fixed -misc-dejavu_sans-medium-r-normal--0-0-0-0-p-0-ascii-0
Fixed -misc-dejavu_sans-medium-r-normal--0-0-0-0-p-0-ascii-0
This did also not work as you can see far below. I had already found and
reported in the past that NXlib does not return the same response as Xlib
when called "font_enumfonts - pattern: fixed" which causes FLTK 1.3.0 to
give up. The old FLTK version did not make a call font_enumfonts on fixed
but assumed that to be present. This resulted in the compiled-in font of
nano-x being used, however, one had only a one size font then.
FLTK has a module called fl_font_x.cxx which contains the default fonts for
FLTK:
static Fl_Fontdesc built_in_table[] = {
{"-*-helvetica-medium-r-normal--*"},
{"-*-helvetica-bold-r-normal--*"},
{"-*-helvetica-medium-o-normal--*"},
{"-*-helvetica-bold-o-normal--*"},
{"-*-courier-medium-r-normal--*"},
{"-*-courier-bold-r-normal--*"},
{"-*-courier-medium-o-normal--*"},
{"-*-courier-bold-o-normal--*"},
{"-*-times-medium-r-normal--*"},
{"-*-times-bold-r-normal--*"},
{"-*-times-medium-i-normal--*"},
{"-*-times-bold-i-normal--*"},
{"-*-symbol-*"},
{"-*-lucidatypewriter-medium-r-normal-sans-*"},
{"-*-lucidatypewriter-bold-r-normal-sans-*"},
{"-*-*zapf dingbats-*"}
};
This is why it queries for -*-helvetica-medium-r-normal--* first. I changed
this array to:
static Fl_Fontdesc built_in_table[] = {
{"-*-dejavu sans-medium-r-normal--*"},
{"-*-dejavu sans-bold-r-normal--*"},
{"-*-dejavu sans-medium-o-normal--*"},
{"-*-dejavu sans mono-bold-o-normal--*"},
[.....................]
This resulted in fonts being found and used.
As you wrote it should also work with a fonts.alias file and that would
avoid a change in the FLTK code. That is what I was trying to get to work
now.
