[openbox] Changing the icon associated to an application

[Al]

Hello,

I'm using openbox 3.4.7.2 and I'd like to change the default icon of some
applications. I've searched in the documentation an found nothing.

I was looking for something like this in the rc.xml file, but this does not work:

  <application class="XTerm">
    <desktop>2</desktop>
    <icon>/home/local/share/sqliteman/icons/database_commit.png</icon>
  </application>

Is there any solution ?

Thanks in advance.
