The sample script introduced in the
previous section
has covered most of the
GAGUI functions and callbacks. However, there are just a few things
that were left out that you may find handy sometimes.
Please consult the following sample scripts:
- sample.gui - this is the script that
we covered in the previous
section
- sample2.gui - a slight variation
of sample.gui with a different layout (single row).
- melrose.gui - similar to
sample.gui but customized for DAO's visualization server
(melrose.gsfc.nasa.gov). Here is an example of how to associate
Help menu items with documents on the Web.
It also contains buttons to open files from the GEOS-1 Reanalysis
residing on a local disk. DAO users on melrose can run this script
with the following GrADS command:
ga-> gui /ford1/local/lib/grads/gui/melrose.gui
or they can set
setenv GAGUI /ford1/local/lib/grads/gui/melrose.gui
for starting it automatically.
- ncep.gui - similar to
sample.gui but has one additional row which allows
the user to open files from the NCEP/NCAR Re-analysis CDROM,
the disc that came with the Bulletin of the American Meteorological
Society (Kalnay et al. 1996).
This script illustrates the chdir() function which allows
the changing current directory to the CDROM mounting point. It also
includes a Help button
which displays ASCII documentation files in the CDROM.
Note: This is script will not work with the
Annual Re-analysis CDROMs being distributed by NCEP.
Exercise: adapt this script for the Annual Cdroms
and contribute your script :-)
- window.gui - this script illustrates
how to create
a secondary GUI window which can be dismissed when no longer
needed. For trying it, start one of the main GUI scripts such as
sample.gui, and from the
File menu, click on
GUI, entering the name of
this script (which, of course, should be copied to your
local disk). A secondary window will pop up with buttons
for opening files in the NCEP/NCAR Re-analysis CDROM,
similar to the middle row in
ncep.gui.
Of course, for getting all the glory details you will need to read the
Reference section.
