- # 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.

- # 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.
