Re: fonts

[Pallucchini Roberto <r palluk virgilio it>]

i'm sorry, but i try but i haben't understand nothing!! ;-))
i have choose the 1 and 3 way that you have tell me, but i have this
problem:

this is the function where i want change the font. I open a dialog
window and i want change the text for "about_text"


void about_app(GtkWidget *widget, gpointer data) {
  GtkWidget *about_win;
  GtkWidget *about_text;
  gchar *title="About...";
  int nmesg;
  int cnt;

  nmesg=sizeof(about_mesg)/sizeof(about_mesg[0]);

  about_win=gtk_dialog_new_with_buttons(title,
                                        GTK_WINDOW (mainwindow),
                                        GTK_DIALOG_DESTROY_WITH_PARENT,
                                        GTK_STOCK_OK,
                                        GTK_RESPONSE_NONE,
                                        NULL);

  g_signal_connect_swapped(GTK_OBJECT(about_win),
                           "response",
                           G_CALLBACK(gtk_widget_destroy),
                           GTK_OBJECT(about_win));

/* Imposto la dimensione della finestra, ne blocco la ridimensionalita'
e blocco il
 * fuoco sulla stessa.
 */
  gtk_widget_set_size_request(GTK_WIDGET(about_win), 260, 90+(6*nmesg));
  gtk_window_set_resizable(GTK_WINDOW(about_win), 0);
  gtk_window_set_modal(GTK_WINDOW(about_win), 1);



/* Inserisco il testo all'interno della finestra e la visualizzo.
 */
  for(cnt=0; cnt<nmesg; cnt++) {
    about_text=gtk_label_new(about_mesg[cnt].message);
    gtk_container_add(GTK_CONTAINER(GTK_DIALOG(about_win)->vbox),
about_text);
  }
  gtk_widget_show_all(about_win);
}


in the first solution i can't call pango_layout_set_font_description
because the text is "char *" and not a "PangoLayout".

in the 3th solution (i think the better way) i need to manage the
PangoAttrList... for create is ok but for set the font or dimension i
need to use pango_attr_list_change?? and in which mode?

thank you ..... i hope don't disturb you! :-))
bye
Roberto

Ps. Excuse me for my poor english :-))
