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.

|
|
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>
|
|

|
|
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.

|
|
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.
|
|
