Hi Ben.
The same as above except change the values after MONO and ARIAL. I've made the values to change in BOLD
struct font_style font_table[] = {
{FONT_FIELD_LABEL, 0, 1, 1, "Mono", 14, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FIELD_VALUE, 1, 1, 1, "Mono", 14, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_LARGE_FIELD, 0, 1, 1, "Mono", 14, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_LARGE_VALUE, 1, 1, 1, "Arial", 24, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_SMALL, 0, 1, 1, "Mono", 10, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_LOG, 1, 1, 1, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FT8_RX,?0, 1, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FT8_TX,?1, 0.6, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_SMALL_FIELD_VALUE, 1, 1, 1, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_CW_RX,?0, 1, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_CW_TX,?1, 0.6, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FLDIGI_RX,?0, 1, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FLDIGI_TX,?1, 0.6, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_TELNET,?0, 1, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FT8_QUEUED, 0.5, 0.5, 0.5, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
{FONT_FT8_REPLY,?1, 0.6, 0, "Mono", 11, CAIRO_FONT_WEIGHT_NORMAL, CAIRO_FONT_SLANT_NORMAL},
};
