+
+2004-08-2? Klaus Niederkrüger <kniederk@math.uni-koeln.de>

+
+2004-07-30 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Added Accels for Const-Buttons
+
+2004-07-29 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Fixed BUG 67984 (thanks to André Wöbbeking)
+	
+2004-07-17 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Fixed BUG 85357
+	
+2004-06-05 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* It was not possible to paste a hex-number starting with "0x" in hex-mode, because hex-mode
+	  prepended automatically "0x" leading to "0x0x...".
+	
+2004-05-16 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Refactored a bit the kcalc_button code. In particular use Richtext only, when needed (a bit faster,
+	  but a lot still to be done).
+	
+2004-05-04 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Masked "&" for the label of the AND button, when displaying the corresponding accel.
+	  Thanks to Sigrid from Trolltech.
+	
+2004-04-27 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Buttons have now their own modes (like inverse Mode etc.)
+	This allows moving tooltips and labels into kcalc_button.cpp
+	instead of having everything in kcalc.cpp.
+	This needs to be cleaned up and the tooltips and labels should be
+	revised.
+	
+2004-04-05 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Changed accel for OR-button from "O" to "|"
+	* More accels are visible, when "Ctrl" is used
+	* disable some buttons like "Sin", "Cos" etc., when not
+	  in decimal mode
+	
+2004-04-05 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Pasted numbers in Hex-Mode are now always interpreted as
+	  hex-numbers (BUG 65167).
+
+2004-03-26 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Centered labels on buttons
+	
+2004-03-24 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Press (and hold) CTRL-key to see accels for all
+	buttons (BUG 69850).
+	
+2004-03-19 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Labels like e.g. "x^y" are drawn with QSimpleRichText
+	  Need to center the labels better!!
+	* KCalcButton supports now two different labels, one for normal, one
+	  for inverse mode. Switch between the two happens via a signal.
+	
+2004-03-11 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Moved functions that paint e.g. "x^y" to the KCalcButton-class.
+	
+2004-03-01 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Created class KCalcButton, which is now used for all QPushButtons.
+	  This will allow later to change the labels more easily, if INV is
+	  pressed, and mucho more...
+	
+2004-02-25 Thomas Weber
+	* "x^2" and "x^y"-buttons have now superscripted labels
+	* pressing "INV"-button changes "x^2"-button to square-root etc.
+	
+2004-02-25 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Changed many accels from "accel()->insert()" to
+	  "button->addAccel()". Fixes BUG 75555.
+	* deactivate EE-button, when Base != DEC  
+	
+2004-02-10 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* First step to fix bug 66397. Changing Basemode via Popupmenu is
+	  too clumsy for most programmers. Maybe backport to KDE 3.2 later,
+	  once it has been tested. GUI does not look nice.
+	
+2004-02-06 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Fixed bug 73437. Pasting empty clipboard made kcalc crash.
+
+2004-02-04 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Moved more accels from keyPressEvent into accels
+	
+2004-01-27 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+        * Fix paste-function: Pasting e.g. "123  \n" did not work
+          because of the trailing spaces and returns.
+
+2004-01-25 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Applied patch from Thomas Weber: Creates buttons C1-C6
+	  to store constants
+
+2003-12-06 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Fix problem with several identical labels in statusbar
+	  with the help of newly added statusbar->hasItem.
+
+2003-12-06 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Make Percent work the way it did in KDE-3.1 again (documentation
+	  was not updated to this KDE-version, which confused me on 2003/08/28)
+	
+2003-11-04 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* More reorganization and preparation for getting accels right.
+
+2003-10-31 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Split Constructor into more subfunctions.
+	  To be continued.
+	
+2003-10-20 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* At last the calculator window resizes, when buttons are hidden/shown
+	* Added a few extra buttons to "fill gaps".
+	
+2003-10-14 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* RadioButtons for Base and Angle converted to PopUpMenu+Button
+	* Layout changed
+	* Moved ENTER form keyPressedEvent to Accel()
+
+2003-10-10 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Number buttons look like numeric keyboard (on US-keyboards that is)
+	* Initialize ToggleActions correctly
+	
+2003-10-09 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Reverted the menubar stuff after several complaints.
+	  Now Kcalc-GUI looks again like on 2003-09-11.
+	
+2003-09-30 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Fixed bug (unitialized pointers)
+	
+2003-09-26 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Moved all type of buttons to menubars, which can be hidden/showed
+	  via the menubar. This is quite experimental and full of bugs.
+	
+2003-09-11 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* Button groups can be switch on/off via actions.
+	  This is not yet the final GUI-Layout (yes, it looks broken).
+	* Accordingly the Stat/Trig-mode has been deleted from
+	  configure window.
+
+2003-09-11 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* deleted a few #includes
+	
+2003-09-02 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* dropped configure-button and Help-button
+	* created menubar with standard-actions
+	* ConfigDialog is not modal anymore
+	* copy/paste/cut-standard actions applied to calc_display
+	
+2003-08-28 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* created Pi-button and moved Inv-button to make space for it
+	* label of "."-button is now localized
+	* Caption is set via signal/slots
+	* Fixed "%"-mode to make it again more conformant with documentation.
+	  "x^y%" does still not work. Did it ever?
+	* Number-keys are now handled by KAccel instead of keyPressEvent
+	* ConfigDialog is modal
+
+2003-08-27 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* moved result_history from CalcEngine into DispLogic
+	* reactivation of rounding towards zero for cos(90) etc.
+	* quit is done in a more KDE conformant way
+	* Caption is set via slots etc.
+	
+2003-08-12 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* continued separation: now display is independent class and
+	  handles everything related to itself.
+	  GUI passes only information between core and display.
+	
+2003-08-04 Klaus Niederkrüger <kniederk@math.uni-koeln.de>
+	* finished the separation of gui-code from the calculating core.
+	  this still needs some clean-up
+	
+2003-02-11 Evan Teran <emt3734@rit.edu>
+	* replaced cheasy stack with STL stack classes (it really should have been
+	  two stacks, but was mushed into one with a linked list dividing content)
+	* made it use new headers (no .h) when _ISOC99_SOURCE is defined
+	* added replace current gui code with ui files to TODO list
+
+2002-05-10 Evan Teran <emt3734@rit.edu>
+	* altered makefile to remove building of it as a library then linking that
+	to a dummy object file, this was silly and caused inclusion of an uneeded
+	source file
+	* bumped version to reflect new options dialog, next version will be 2.0.0
+	as it will have many new changes/features
+
+2002-03-11 Evan Teran <emt3734@rit.edu>
+	* started work on making calculator code _seperate_ from the
+	gui code, the goal here is the make the calculating core
+	replacable with any library (hopfully with better precision) simply by
+	wrapping it in a class
+	* made it some many buttons are disabled when unavailabled (A-F) not enabled
+	unless we are in HEX mode, less confusion for users who arent familiar with
+	different bases
+	* removed some code that is never getting called
+	* why oh why are exceptions disabled in the standard config, I would like to
+	use them :(
+	
+2001-10-18 Evan Teran <emt3734@rit.edu>
+	* removed configdlg.* from source tree as it is not part of the compile
+	* changed options dialog to use smarter layouts, and also fixed spinbox
+	size problem so they are now usable
+	* synced changed I made to the KDE 2.2.1 release version to match CVS
+	version which compiles under KDE 3.0 w/ QT 3.0.0
+	* made sure the clear (clear entry) button functioned properly, my minor
+	change before broke it in some situations
+
+
+2001-10-12 Evan Teran <emt3734@rit.edu>
+	* Reorganized code for all files, much more consistant now
+	* completely reworked the cvb (convert to binary) function
+	it now is sane, the last one did a rediculous amount of
+	unneeded work
+	* changed C/C++ headers to use new style as per ANSI/ISO 
+	standard
+	* removed fontdlg.cpp/h from tree, not even used in compile :P
+	* made binary mode 32-bit
+	* reorganized UpdateDisplay code to make more sense
+	* found possible nasty memleak in EnterEqual
+	* now use my UNUSED macro to perform (void)var on unused parameters
+	to avoid compile warnings, much more readable this way
+	* merged setXXX functions to angle_selected/base_selected
+	then removed the setXXX functions as they no longer have any purpose
+	* changed a ton of code to use true C++ bools, makes logic
+	more clear
+	* made cvb a static member of QtCalculator instead of an ugly global
+	function
+	* changed history to use a simple vectory object instead of the storing
+	the values in a dynamically allocated QList, it was clearly leaking memory
+	as it was almost never released, this could have been fixed by enabling the
+	autodelete feature of QList...but why dynamically allocate when we are
+	storing numerical values?!? simple array with an int as an iterator :)
+	* changed error trapping from C style signal trapping, rather use exceptions
+	much cleaner that way
+	* removed un-used TopOfStack function
+	* fixed ability to enter a decimal point when in hex/oct/bin mode, those are
+	integer value only modes
+	* fixed problem with entering multiple decimal points in decimal mode
+	* changed CALCAMNT to be defined by a typedef, I did notice that at least my
+	C++ math headers are broken...functions like cos should (by newest
+	standards) use float, double, or long double versions automatically based on
+	datatype, however mine (Redhat 7.1) seems to only have the old double
+	versions, and have alternate names for these functions
+	* fixed the fact that the normal clear button seemingly did nothing
+
+
+1999-08-22  Bernd Johannes Wuebben  <wuebben@math.cornell.edu>
+
+	* kcalc_core.cpp (UpdateDisplay): 
+	Re-enabled the use of long double. Most if not all distributions
+	come now with a working glib math library. 
+
+Mon Nov 16 18:05:01 1998  Mario Weilguni <mweilguni@kde.org>
+
+	* There was an error in the stdev forumal. Fixed.
+	* the population standard deviation had the same fault. Fixed.
+
+Mon Nov 16 18:05:01 1998  Mario Weilguni <mweilguni@kde.org>
+
+	* calculation the facturial of a too large number was delayed,
+	even though infinity was already reached. Now kcalc stops
+	calculation if infinity is reached and displays an error
+
+Mon May  4 06:28:09 1998  Bernd Johannes Wuebben  <wuebben@math.cornell.edu>
+
+	* Added the comma key as an accelerator for '.'
+
+Sat Apr 18 16:26:52 1998  Bernd Johannes Wuebben  <wuebben@math.cornell.edu>
+
+	* Some inverse functions didn't compute right. Wonder who broke them.
+
+Sun Feb  8 16:11:34 1998  Bernd Johannes Wuebben  <wuebben@math.cornell.edu>
+
+	* removed a compiler warning
+
+Sat Nov 22 14:30:37 1997  Bernd Johannes Wuebben  <wuebben@petit.cornell.edu>
+
+	* stats.cpp: fixed some bugs in the stats module
+	  mean should now be correct
+	  std  shoudl now be correct too.
+
+Sat Sep 20 23:59:30 1997  Bernd Johannes Wuebben  <wuebben@petit.cornell.edu>
+
+	* kcalc.cpp: Added statistical functions
+
+Mon Sep 15 00:34:58 1997  Bernd Johannes Wuebben  <wuebben@petit.cornell.edu>
+
+	* added cut and pasted functionality
+	* implemented EE 
+	* implemented result stack
+	* implemented precision and fixed precision 
+	* added key bindings
+	* tooltips
+	* added configuration dialog
+	
+
+Sat Aug  2 22:06:59 1997  Bernd Johannes Wuebben  <wuebben@petit.cornell.edu>
+
+	* kcalc.h: clean up
+	
+
