The values are: - default -> widget decides - up -> always up unless widget doesn't support - down -> always down unless widget doesn't support - vertical -> vertical is down or leaves the choice to the widget between up & down (depending on available space, etc...) - ltr/right -> always to the right unless widget doesn't support - rtl/left -> always to the left unless widget doesn't support - horizontal -> ltr by default, rtl if mirrored. also leaves the choice to the widget between ltr & rtl (depending on available space, etc...) Most widgets only implement horizontal vs. vertical so unsupported direction are converted to either of H or V. We still need to audit all our EO widgets to make sure they respect horizontal + mirrored properly. -- Jean-Philippe André ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
