please find as attachment, a sample with a custom Gtk TextBuffer and a
custom TextTag.
link to the TextTag vala doc: http://valadoc.org/#!api=gtk+-3.0/Gtk.TextTag
here a few documentation of text tags parameters :

> Hi list,

> I've compiled and tested this C-tutorial that shows how to have different
> fonts, colors and and sizes in a single text box:

>
> GtkWidget *text;
> ...
> text = gtk_text_new (NULL, NULL);
> ...
> fixed_font = gdk_font_load ("-misc-fixed-medium-r-*-*-*-140-*-*-*-*-*-*");
> ...
> gtk_text_insert (GTK_TEXT (text), fixed_font, &text->style->black,
> NULL,"Hello\n", -1);
>
>
> Now I'd like to do the same in Vala. I've looked through valadoc and what
> valencia's completion would provide. But I couldn't find the keywords I
> expected in the Gtk namespace. Basically, I need an object that provides
> the gtk_text_insert(...) function, which allows me to add formatted text
> immediately.

> VteTerminal, SourceView and TextView seem to be too limited, as they
> doesn't seem to provide such a function. Or am I just to blind to find a
> substitude that is as rich?
>
> My understanding of creating GIR and VAPIs is not sufficient, but I think
> I wouldn't have to do this for gtktext.h, because the whole gtk-library is
> available to vala already?

> I'll be happy about any input. Thanks a bunch in advance.
