Pango-CRITICAL **

General
1

I new get Errors in the order:
Pango-CRITICAL **: 19:48:05.403: pango_font_description_set_family: assertion ‘desc != NULL’ failed
I get this error in the statements:
Set_Family(MainWindow.FD,“Times New Roman”);
and
Set_Size(MainWindow.FD, Gint(SC_CH_Size));
FD comes from
FD := Pango_Font_Description_new;
I am sure that these two statements are the ones that cause the failure because if I outcomment the statements the error disappear. Maybe there is somewhere an example how to use the pango routines

declare
   Font  : Pango_Font_Description;
   Label : Gtk_Label;
begin
   Font := From_String ("Arial 16");
   Gtk_New (Label);
   Label.Modify_Font (Font);
   Label.Set_Text ("Hello World!");
   Free (Font);
   ...

P.S. Never set fonts this way. Gtk uses CSS for the purpose either directly or using property styles.
