I think for now we should disable it for MacOS until a solution presents
itself, maybe I will get a Macbook so I can test this.
John, is this right...
void
gnc_assoc_cell_set_use_glyphs (AssocCell *cell)
{
#ifdef MAC_INTEGRATION
cell->use_glyths = FALSE;
#else
gboolean use_glyphs = TRUE;
gchar *test_text;
GtkWidget *label;
PangoLayout *test_layout;
gint count;
g_return_if_fail (cell != NULL);
label = gtk_label_new (NULL);
test_text = g_strconcat (GLYPH_LINK, ",", GLYPH_PAPERCLIP, NULL);
test_layout = gtk_widget_create_pango_layout (GTK_WIDGET (label),
test_text);
pango_layout_set_text (test_layout, test_text, strlen (test_text));
count = pango_layout_get_unknown_glyphs_count (test_layout);
if (count != 0)
use_glyphs = FALSE;
g_object_unref (test_layout);
g_free (test_text);
cell->use_glyphs = use_glyphs;
#endif
}
