Changes to CCGVU Version 5.3.0
January 31, 2003
-
Data is now obtained from the CCGG MySQL database,
instead of the standard text files.
-
Modified the Open dialog. There are no longer multiple
pages depending on the data type. A single combo box
is used for selecting the data type.

Added character validation on
entry boxes requiring only a float or integer number.
Changes to CCGVU Version 5.2.1
September 13, 2002
-
Modified the Import dialog. Included options for
specifying the number of lines to skip at the
beginning of the file, and optionally specify values
to ignore while reading the file.
-
Fixed bug where statistics dialog could be destroyed
by user having window manager destroy window, instead
of using the 'Close' menu button. This caused an error
when opening new data files and trying to update the
statistics window, which no longer existed.
-
Fixed In-situ open dialog so that it will properly handle
an entry of the station code instead of a station name.

Revised the Open dialog, adding a notebook for the
different data type options, adding options for binned
shipboard data and binned aircraft data. Also split
up the in-situ and flask options to different pages.
Revised flask and in-situ pages to allow entering a

instead of using a static list of site codes.

-
Added a title to the graphs, based on either the station code
for data obtained from the 'Open' dialog, or the file name for
data obtained from the 'Import' dialog.

Changes from version 4.40 to 5.0.0
April 2002
ccgvu has undergone a complete change from a C/Motif based
application to a tcl/tk front end with C backend programs.
The front end graphical interface uses the blt graph widget
for displaying the data, and the BWidget toolkit for tcl/tk.
This has resulted in a simpler interface, additional features,
and faster development.
