-- $Id: README,v 1.3 2002/07/27 16:19:29 tom Exp $ ------------------------------------------------------------------------------- This is a modified/enhanced version of Cdk. The original README contents are given below. The intent of the modifications is to preserve nominal compatibility with the original Cdk, while fixing bugs and design limitations. Some macros such as ObjOf() have been introduced to deal with these, which could be added to the original for a side-by-side comparison. This version of Cdk is found at http://invisible-island.net/cdk/ ftp://invisible-island.net/cdk/ -- Thomas Dickey ------------------------------------------------------------------------------- Cdk Readme Guide Copyright Mike Glover, 1995, 1996, 1997, 1998, 1999 ------------------------------------------------------------------------------- Overview: --------- Cdk stands for 'Curses Development Kit' and it currently contains 21 ready to use widgets which facilitate the speedy development of full screen curses programs. This little project of mine started as a test to see how compatible my Linux machine was to other UNIX breeds. While doing this I discovered Ncurses, and played with it. These widgets are the result of over a years worth of playing. The current complement of widgets are: Widget Type Quick Description =========================================================================== Alphalist Allows a user to select from a list of words, with the ability to narrow the search list by typing in a few characters of the desired word. Buttonbox This creates a multiple button widget. Calendar Creates a little simple calendar widget. Dialog Prompts the user with a message, and the user can pick an answer from the buttons provided. Entry Allows the user to enter various types of information. File Selector A file selector built from Cdk base widgets. This example shows how to create more complicated widgets using the Cdk widget library. Graph Draws a graph. Histogram Draws a histogram. Item List Creates a pop up field which allows the user to select one of several choices in a small field. Very useful for things like days of the week or month names. Label Displays messages in a pop up box, or the label can be considered part of the screen. Marquee Displays a message in a scrolling marquee. Matrix Creates a complex matrix with lots of options. Menu Creates a pull-down menu interface. Multiple Line Entry A multiple line entry field. Very useful for long fields. (like a description field) Radio List Creates a radio button list. Scale Creates a numeric scale. Used for allowing a user to pick a numeric value and restrict them to a range of values. Scrolling List Creates a scrolling list/menu list. Scrolling Window Creates a scrolling log file viewer. Can add information into the window while its running. A good widget for displaying the progress of something. (akin to a console window) Selection List Creates a multiple option selection list. Slider Akin to the scale widget, this widget provides a visual slide bar to represent the numeric value. Template Creates a entry field with character sensitive positions. Used for pre-formatted fields like dates and phone numbers. Viewer This is a file/information viewer. Very useful when you need to display loads of information. =========================================================================== Each widget has the ability to display color, or other character attributes. Cdk comes with a attribute/color format command set which allows a programmer to add colors and characters attributes simply. The code has been cleaned using both Purify(TM) and Sun's Testcenter(TM), so it is as clean as a babies butt. :) Any leaks I have seen are in the curses libraries; there is nothing I can do about that, sorry. There should be no memory leaks within the code, it shouldn't core dump, and it shouldn't do anything unexpected. Unfortunately this probably is not the case. If you do see something like this tell me after you read the BUGS file. Distribution: ------------- This distribution has a full complement of manual pages, so any specifics to the widgets will not be addressed in this read me. If you want to get right in there, nroff the cdk.3 file in the man directory. It is the starting point for all the manual pages. There are some other files to look at if you want to get anywhere. They are: INSTALL - This will show you how to build Cdk and install it on your system. If there are any personal modifications that you think may be needed, read this file. In fact read it regardless. :) COPYING - The legal stuff to protect my butt and all of the hard work that I have put into this library. EXPANDING - You feel creative enough to add a widget, here are my requirements that you have to follow to make the integration of a new widget seamless. BUGS - What to do when you find a bug. It also lists all of the bugs found, who found them, who fixed them, and when they were fixed. If you think you have found a bug look at this file. If you do not think you have the most up to date version of Cdk, go get it and try to replicate the problem. Then look at the BUGS file again. If it is NOT there, then you can mail me notifying me of a possible bug. I will try my hardest to get back to you, but I have a pretty busy schedule so don't expect an instant reply. This file will also explain how I would like any bug fixes sent to me. NOTES - Misc babblings of myself somewhat related to this distribution. TODO - A list of things I plan to do in the future. (sleep) CHANGES - A list of changes from one release to another. If you want to get a hold of me mail me at one of the following: glover@credit.erin.utoronto.ca mike@vexus.ca The CDK Web page has several homes. They are: http://www.vexus.ca/CDK.html (official) http://www.datasoft.on.ca/~cdk (Sponsored by the nice folks at Datasoft) ttfn, Mike PS: There is also a Perl5 extension of this library for you Perl5 fans. Look under any CPAN site under the directory CPAN/authors/id/GLOVER.
