7.3.1.4 Rotating Displays
.........................

Arrays, structures and lists can be oriented horizontally or vertically.
To change the orientation of a display, select it and then click on the
`Rotate' button.

   As a faster alternative, you can also press _mouse button 3_ on the
array and select `Rotate' from the popup menu.

   If a structure or list is oriented horizontally, DDD automatically
suppresses the member names.  This can be handy for saving space.

   The last chosen display orientation is used for the creation of new
displays.  If you recently rotated an array to horizontal orientation,
the next array you create will also be oriented horizontally.  These
settings are tied to the following resources:

 -- Resource: arrayOrientation (class Orientation)
     How arrays are to be oriented.  Possible values are `XmVERTICAL'
     (default) and `XmHORIZONTAL'.

 -- Resource: showMemberNames (class ShowMemberNames)
     Whether to show struct member names or not.  Default is `on'.

 -- Resource: structOrientation (class Orientation)
     How structs are to be oriented.  Possible values are `XmVERTICAL'
     (default) and `XmHORIZONTAL'.
