In the Advanced window tx, ty refer to the positioning of any display
text that Denemo displays with this Directive, gx, gy refer to the
position of any graphic displayed with the directive. The only things
affecting the LilyPond syntax output are the LilyPond prefix and
postfix fields and the override flag (the override flag tells Denemo
what to do with the bits of syntax in the pre- and post- fix fields -
where to put them relative to the syntax for the note etc).

In the Object Editor the Denemo Directives are grouped into a widget
called a GtkFrame - it is supposed to draw a box around all the stuff
for that directive and to have a little triangle marker that allows you
to expand or collapse the frame to save space on the screen. Some bug
in GTK for Windows is making this behave strangely, hopefully that will
go away when we can build Denemo for Windows with a newer version of
Gtk.

The frame collapses down to just the title which should have a little
triangle before it, indicating that you can expand it by clicking
there.
