Re: [Vala] Pango.Context.list_families

[Chris Daley <chebizarro gmail com>]

Hi there,

The list_families method takes an array as an out parameter. You need to
declare a FontFamily array and then pass it to the method like this:

// your existing code

fam: array of FontFamily
context.list_families(out fam)

With your existing code, it will return a zero length array. If you want to
get a list of all of the Font Families available to the existing GDK
screen, you can replace the line:

var context = new Pango.Context()

with

var context = Gdk.pango_context_get()

Hope this helps
Cheers
Chris D
