Description
Constructs a widget for the entry of measures direction values.
The allowed formats for user input are:
- The direction reference frame may be chosen using the
left hand button, and the latitude and longitude entered
in the next two entry boxes. The allowed formats for
times and angles are described in the quanta
tool.
- A planet may be selected using the left hand button
- One of a list of bright radio sources may be selected using the
SourceList button under the spanner/wrench.
- The name of Glish variable or function that evaluates to a
direction measure.
Note that changing the reference frame does not change the
values in the entry boxes. Instead, it defines the frame with the
currently specified values. If you wish to make a conversion, use the
measures direction gui.
The options string can be used to specify vertically aligned
entries.
