# window.gui - last revision: October 12, 1997
#
# This script demonstrates how to create a separate GUI window.
#
# Sample widget script for creating a separate window for the
# NCEP/NCAR Re-analysis CDROM. Modify the first line ("chdir")
# for the location of your CDROM drive.
#
# How to invoke this script:
#
# Start one of the more general purpose GUI scripts, say sample.gui,
# by entering at the command line:
#
# ga-> gui sample.gui
#
# The from the "File" menu, select GUI, and enter the name of this
# script (window,gui). A second window shall pop-up.
#
# NOTES:
#
# 1. Do not invoke this as your main GUI as it lacks many
# vital functions (such as a "QUIT" button).
#
# 2. Do note invoke this script from the "ncep.gui" script
# as to avoid widget naming conflicts.

# Note: Do not call MainLoop() when you have used MakeWindow()

#
# APPENDIX: Currently available callback functions
#
# Browse Opens a text file, such as a help file, on a separate
# window.
# Cmd Executes a generic GrADS command
# CmdStr Like Cmd, but the user is prompted for an additional
# string to be appended to the GrADS command.
# CmdWin Invokes a window for GrADS command line interface.
# User can click on past commands from a list.
# CmdLine Invokes the standard GrADS command line interface.
# When the command line is active the other widgets
# are not available (may be fixed in the future).
# CloseWindow Closes the current window (do not use for your primary
# window or you will get stuck).
# Display A generic callback for displaying the current variable
# (or expression) set with VarSel. The options are:
# << decrements time and executes display
# PLAY starts animation from current to last time
# DISPLAY just executes display
# >> increments time and executes display
# If the "hold" toggle state is OFF (the default),
# the screen is cleared before displaying.
# Edit Like browse, but the user can edit the file. This simple
# text editor is integrated with GrADS, providing a very
# elementary Integrated Development Enviroment (IDE) for
# GrADS scripts. In particular, the script being edited
# can be executed by clicking on a button (not
# implemented yet).
# FileSel Pops up a scrollable list and asks the user to selected
# a file among the currently opened GrADS files (including
# SDFs). The selected file becomes the default.
# Load Pops up a "file finder" widget, and after the user
# clicks on a file name it executes a GrADS command
# specified as the last argument. In case of "open" or
# "sdfopen" the files becomes the default, and the
# user is asked to select a variable from this file.
# Open Similar to Load, but the file name must be specified.
# Toggle Turn internal options ON/OFF. The only internal
# option currently supported is "hold". This callback is
# usually used with MakeToggle(), see example above.
# VarSel Pops up a scrollable list and asks the user to selected
# a variable from the default file. The user can also
# type a generic GrADS expression instead of selecting
# a single variable.
# NULL Does not do anything, used for inactive buttons.
