If you find a bug, and want me to fix it, you will need to do a few things for
me.
* Give me a copy or part of the code which demonstrates this bug. If
you can't do this, then replicate the bug in a piece of test code
and send me that.
* Make sure you can replicate the bug. Then send me the of instructions
on how to replicate the noted bug.
If you do this, I will mail you back telling you if the information was
sufficient or not. If it is, I will tell you when I hope to have this bug
licked by. If you need an urgent update (i.e., your boss is crawling down your
throat for your program to work) tell me, I'll get to it ASAP.
If you find a bug and fixed it yourself, I will need the same as above with a
few extras.
* I will need a patch of any piece of code you made so I can apply it
to what I have.
* Tar this up and send it to me.
If you have found and fixed a valid bug, you will be noted in the next
distribution of this bugs file, and my warmest thanks for reducing my ever
growing workload. :)
Here is the noted list of outstanding bugs and bugs of the past...

character. (the cursor always seemed to be a
character to the right.)
------------------------------------------------------------------------------
4.8.2 Entry Irrational behavior when the entry field is Jan/97
shorter than the text which occupies it.
Bug found and fixed by
Guy Finney <gaf@primenet.com>
4.8.2 All Widgets Didn't check if the shadow window was NULL Jan/97
or not when performing operations on the
WINDOW pointer.
4.8.2 All Widgets Registration/unregistration of widgets did Jan/97
not work correctly. Caused SEGV when alot
were killed and a refresh was called.
Did not adjust the screenIndex value of
the widget if a widget before it was killed.

destroyed.
4.8.2 Alphalist Fixed uninitialized memory reads and leaks. Jan/97

4.8.2 All Widgets Re-purified all widgets and fixed all Jan/97
problems found.
4.8.2 All Widgets Found a problem when putting a CDK widget in Jan/97
a curses window. When an absolute x/y
coordinate was provided, the x/y position
it was assigned was based on the main window
and not the window it was being attached into.
This problem only occurs when a window other
than the one one created via initscr was being
used.
4.8.2 Template When setting the value of the template widget, Mar/97
the cursor usually got mixed up as to where
it should be compared to where it has to be.
4.8.2 Swindow The scrolling window would core out if too many Mar/97
lines were added. This was because I never
checked the maximum lines value supplied
when the widget was created.
------------------------------------------------------------------------------
4.9.0 Dialog The separation line on the widget was being April/97
drawn too far if the curses breed was not
ncurses.
4.9.0 Viewer The separation line on the widget was being April/97
drawn too far if the curses breed was not
ncurses.
4.9.0 Matrix The boxwidth would not get calculated correctly April/97
when a weird mixture of rows/columns and
spacing was used.
4.9.0 Swindow Centered text did not scroll correctly. May/97
4.9.0 Fselect Fixed cut and paste typo in the May/97
setCDKFselectXXXAttribute functions. Thanks
to andrze@tor.supercomputing.com for
pointing this out.
------------------------------------------------------------------------------
4.9.1 Scroll Fixed the scrollbar height. The bar was always July/97
being made to the height of the list and not
the height of the window.
4.9.1 Selection Fixed the scrollbar height. The bar was always July/97
being made to the height of the list and not
the height of the window.
4.9.1 Radio Fixed the scrollbar height. The bar was always July/97
being made to the height of the list and not
the height of the window.
4.9.1 All When a signal was set the signal would return July/97
and end up in the character binding routines
and pass in a bogus value for the key. This would
cause the index to be set to some wild value and
cause a bus error.
4.9.1 Scroll When drawing the scroll bar, I never checked if July/97
the scroll bar window was NULL.
4.9.1 Selection When drawing the scroll bar, I never checked if July/97
the scroll bar window was NULL.
4.9.1 Radio When drawing the scroll bar, I never checked if July/97
the scroll bar window was NULL.
4.9.1 Label Added the functions activateCDKLabel for the July/97
builder. The function calls drawCDKLabel
4.9.1 Graph Added the functions activateCDKGraph for the July/97
builder. The function calls drawCDKGraph
4.9.1 Graph Modified the draw function, so if setCDKGraph July/97
has not been called, it doesn't core dump.
4.9.1 Alphalist When the user hit tab after entering a simple July/97
string in the entry field, the widget would
core out because I didn't check for an upper
bound on the array inside the while loop.
4.9.1 Slider When the user asked for a full width slider by July/97
passing in FULL or 0, it cored out.
4.9.1 All Found a major bug in alignxy (which all Sept/97
widgets called). This affected a widgets
alignment when a widget was created in a
window that was not the full screen.
------------------------------------------------------------------------------
4.9.2 Template Fixed a small bug in which internal variables Jan/98
of the template widget were reading past their
array bounds. (Array Bounds Read with purify)
Possible source of SEGV or core dumps.
------------------------------------------------------------------------------
4.9.3 Button Box Fixed an oversight with the buttonbox key Apr/98
key bindings. Bug and patch fix/found by
Mark Buckaway <mark@datasoft.on.ca>.
(thanks :) )
------------------------------------------------------------------------------
4.9.4 Complete mystery as to what happened these April
months. Must have been kidnapped by aliens. to
Several individuals did send in patches to July
make this 8-bit clean. If the sysadmin at of
the office didn't nuke everyones mailbox, I 1998
could give them credit. If you know who you
are, please mail me, I'll give you credit.
------------------------------------------------------------------------------
4.9.5 Template The Pre-Process function would never get July/98
called becuase of cut-and-paste problems
during development.
------------------------------------------------------------------------------
4.9.6 None reported. Yeaahhhhhhhh!!!!!!!!!!!!!!! Whoo hooooo!!!!
4.9.7
