Subject: Set widgets orientation according to the panel orientation.
Newsgroups: gmane.comp.desktop.xfce.commits
Date: Thursday 14th February 2013 20:00:01 UTC (over 3 years ago)
Updating branch refs/heads/master
         to 34b77702471d93f2d8f19e736d616ea0b01f4664 (commit)
       from e55a418bd9d8c284774d7b8ac33aff0356a5a4ab (commit)

commit 34b77702471d93f2d8f19e736d616ea0b01f4664
Author: Harald Judt 
Date:   Mon May 21 10:54:00 2012 +0200

    Set widgets orientation according to the panel orientation.
    
    This makes the plugin rotate its widgets in vertical mode
    and introduces support for panel-4.10 features, like the new
    deskbar mode.
