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.
