attachments in SUGAR.quickCompose.init

[Alexand]

Hi all !
It is known, that button with text below calls quickCompose form. How can I pass attachments to it ?

What shold be under [] in " attachments:[] " ?

<input type="submit" title="Compose Email [Alt+L]" accesskey="L" onclick="SUGAR.quickCompose.init({"fullComposeUrl" :"parent_id=replace-whith-your-parent-record-id&amp;parent_type=Contacts","composePackage":{"to _email_addrs":"Mr. Firstname Surname &lt;mail@mail.com&gt;","parent_type":"Contacts","p arent_id":"replace-whith-your-parent-record-id","parent_name":"Mr. Firstname Surname","subject":"","body":"","attachments":[],"email_id":""}});" class="button" name="button" value="Compose Email"
