// Revision 1.1  2003/09/08 19:42:03  jasonk
// Addition of packages directory and associated files.
//
// Revision 1.1.1.1  2003/08/07 21:18:32  jasonk
// Initial import of PIXIL into new cvs repository.
//
// Revision 1.1.1.1  2003/06/23 22:04:23  jasonk
//
//
// Revision 1.1.1.1  2000/07/07 16:10:58  jasonk
// Initial import of ViewML
//
// Revision 1.122.4.3  1999/06/14 10:37:47  porten
// const char* for string constant
//
// Revision 1.122.4.2  1999/04/22 23:04:13  pfeiffer
// I think http://buglist.kde.org is deprecated, so I changed it (in the
// about-box) to http://bugs.kde.org, as in the HEAD-Branch.
//
// Revision 1.122.4.1  1999/04/13 00:20:22  dmuell
// don't create /.kde/share/config for kdm.
//
// Revision 1.122  1999/01/18 10:56:12  kulow
// .moc files are back in kdelibs. Built fine here using automake 1.3
//
// Revision 1.121  1999/01/15 09:30:30  kulow
// it's official - kdelibs builds with srcdir != builddir. For this I
// automocifized it, the generated rules are easier to maintain than
// selfwritten rules. I have to fight with some bugs of this tool, but
// generally it's better than keeping them updated by hand.
//
// Revision 1.120  1999/01/10 14:48:47  ettrich
// fixed default widget style
//
// Revision 1.119  1998/12/13 20:32:57  ettrich
// reverted some of the previous changes
//
// Revision 1.118  1998/12/13 20:04:16  ettrich
// yet another fix for user defined SM
//
// Revision 1.117  1998/12/13 18:03:54  ettrich
// bugfix for user defined session management
//
// Revision 1.116  1998/12/05 01:32:59  ettrich
// support for icon text
//
// Revision 1.115  1998/11/08 19:06:43  esken
// Several security fixes by adding checkAccess() tests before the creation
// of files and directorys. This is neccesary for SUID programs. Added
// checkAccess(), which checks if the user may write a file.
//
// checkAccess() is a global function, perhaps it should be moved to some
// KTools class as static member funtion later.
//
// Revision 1.114  1998/10/12 13:22:54  ettrich
// Matthias: small fix
//
// Revision 1.113  1998/10/12 00:17:09  ettrich

// Revision 1.112  1998/09/28 07:54:23  garbanzo

// Use paths.h if we can.
//
// Revision 1.110  1998/09/10 23:47:29  markus
// //$markus: replaced NULL with 0L in aboutKDE(). This caused trouble on
// the netwinder.
//
// Revision 1.109  1998/09/01 20:21:14  kulow
// I renamed all old qt header files to the new versions. I think, this looks
// nicer (and gives the change in configure a sense :)
//
// Revision 1.108  1998/08/23 15:58:31  kulow
// fixed some more advanced warnings
//
// Revision 1.107  1998/08/11 00:24:57  steffen
// KProcess stuff removed
//
// Revision 1.106  1998/07/23 20:55:11  ettrich
// Matthias: new configurable keybindings
//
// Revision 1.105  1998/07/02 15:42:42  ettrich
// Matthias: Added a new signal
//
//                  void shutDown();
//
//           which is emitted when the client is killed (for example via
//           kwm's logout)
//
// Revision 1.104  1998/06/21 15:03:37  konold
//
// Martin K.: Fixed typo            Coolo does this affect the translations?? Please check.

// applied patch to replace .kde with localkdedir()
//
// Revision 1.102  1998/05/28 21:43:52  kulow
// removed TESTDIR. Since kdedir() is protected, it shouldn't happen anymore :)
//
// Revision 1.101  1998/04/12 08:52:36  jacek
//
// * Updtated KCharset class documentation.
//
// * Chnged font entry in config files to store charset as string, not numerical
//   id (which worked only for iso-8859-* charsets)
//
// * added KCharset::xCharset method for getting charset name to use for X font
//   names.
//
// Revision 1.100  1998/04/03 14:25:59  kulow
// fixed a memory leak
//
// Revision 1.99  1998/03/27 17:27:31  mark
// MD:
// - Added call to setWinStyleHighlightColor()
// - changed disabled text color from darkGray to colorGroup().mid()
// - changed config keys and groups to read color scheme and fonts
// - used readFontEntry for reading generalFont and fixedFont
//
// Revision 1.98  1998/03/21 23:05:12  mark
// MD: Addition of a new font, a fixed font, for general use in applications.
// Unfortunately, I think this is a BINARY INCOMPATIBLE change. (Cleared with Kalle.)
//
// Revision 1.97  1998/03/12 21:17:01  wuebben
// Bernd: updated 'about KDE' text. It is now more in line with KDE goals
//
// Revision 1.96  1998/03/11 11:22:24  kulow
// use readColorEntry instead of the old way. This is more consistent
//
// Revision 1.95  1998/03/09 20:20:11  kulow
// - set KApp to 0, after the destructor has run. After that, nothing is for sure
// - remove widgetList given by QApplication::topLevelWidgets. You can see this
//   in the documentation
//
// Revision 1.94  1998/02/24 21:36:04  kulow
// fix for invokeHTMLHelp: missing / behind the path
//
// Revision 1.93  1998/02/24 21:16:22  kulow
// remove kde_minidir, since this is somehow stupid (I hard coded it in the
// Makefiles as icondir/mini now) and added kde_sounddir
// This is even source incompatible, but it hasn't been used, so it should
// work after some little changes I will make
//
// Revision 1.92  1998/02/24 20:07:45  kalle
// Added F1 accelerator to standard help menu
//
// Revision 1.91  1998/02/24 15:54:29  kulow
// replaced some hard coded paths with the kapp->kde_ methodes.
// I'm not sure, if kde_datadir() is optimal for /share/apps ;)
//
// Revision 1.90  1998/02/20 06:21:18  kalle
// Don't connect the Help/About slot when there is no text for an about box
//
// Revision 1.89  1998/02/19 05:58:22  rwilliam
// Modified getHelpMenu()
//    Now displays Content instead of Help...
//
// Revision 1.88  1998/02/07 20:44:05  kulow
// good news: KDE is relocatable again. kdelibs's configure is now inserting KDEDIR in the directories name and the kde_dir functions check for this.
// This way we can have the advantages of both sides. It's relocatable with $KDEDIR
// and you can hardcode specific directories, if you don't use relative paths.
// All, that is needed now is to patch the applications to use the kapp::kde_ functions
//
// Revision 1.87  1998/01/27 20:17:01  kulow
// applied patch by Kalle to make invokeHTMLHelp use the locale setting.
//
// Revision 1.86  1998/01/25 20:35:48  kulow
// corrected order of signal and action (a party for the four-eyes-strategy ;)
//
// Revision 1.85  1998/01/25 20:09:43  kulow
// patch created by me after Mario told me, what to do ;)
// applyGUIStyle does not work exactly like QApplication::setStyle
//
// Revision 1.84  1998/01/22 16:29:45  jacek
// Default locale's charset support added
//
// Revision 1.83  1998/01/17 07:35:16  kalle
// Uh-oh...
//
// Revision 1.82  1998/01/16 21:29:30  kalle
// mention the new bug site in the about dialog
//
// Revision 1.81  1998/01/03 15:24:33  kulow
// added accelerators and ... to the returned Help - Menu
//
// Revision 1.80  1997/12/31 14:12:25  kulow
// corrected grammar and added one more .copy()
//
// Revision 1.79  1997/12/29 14:36:46  kulow
// kdedir() does no longer return a deep copy, but a shallow copy.
// I inserted a test against a deep copy to take care of changes. But this
// is just to find problems and can be removed by undefining TEST_KDEDIR in
// Makefile.am
//
// Revision 1.78  1997/12/28 21:32:14  kulow
// last time I forgot two functions kde_mimedir() and kde_confdir()
// I will move this functions very soon to static functions of a new
// class KPaths. Kapplication is not the optimal class to contain this
// functions, since I need a DISPLAY to find out the paths. But I think,
// we can create some inline methods in kapp then
//
// Revision 1.77  1997/12/13 15:08:56  jacek
// KCharsets support added
// WARNING: kderc file format has changed. Since now charset name
// instead of id is stored.
//
//
// Revision 1.76  1997/11/27 20:21:20  kulow
// safer deletion of theKProcessController by Johannes Sixt.
// Read the comments for details
//
// Revision 1.75  1997/11/21 11:22:29  kulow
// make a deep copy of kdedir before returning it. I still don't get it,
// why this is necessary.
//
// Revision 1.74  1997/11/20 22:41:32  kalle
// Small bug fix in kapp.cpp (I hope this does not break anything...)
// First element of search was $HOME./kde and is now $HOME/.kde
// New version looks way more correct to me...
//
// Revision 1.73  1997/11/20 22:24:30  kalle
// new static methods for the various directories
//
// Revision 1.72  1997/11/18 21:40:41  kalle
// KApplication::localconfigdir()
// KApplication::localkdedir()
// KConfig searches in $KDEDIR/share/config/kderc
//
// Revision 1.71  1997/11/11 05:41:53  wuebben
// Bernd: implemented iso charset support
//
// Revision 1.70  1997/11/09 04:08:54  wuebben
// Bernd: iso charset changes (minimal and harmless )
//
// Revision 1.69  1997/11/03 14:41:28  ettrich
// Matthias: tiny fix for command line arguments: "-icon" will also be used
//       for the miniicon if "-miniicon" is not defined.
//
// Revision 1.68  1997/11/03 13:50:15  kulow
// delete theKProcessController in the destructor
//
// Revision 1.67  1997/10/30 13:30:15  ettrich
// Matthias: fix for setWmCommand: now setWmCommand can also be used for
//   PseudoSessionManagement (this is the default when session management
//   was not enabled with enableSessionManagement).
//   Now KApplication should work as promised in kapp.h :-)
//
// Revision 1.66  1997/10/25 22:27:40  kalle
// Fixed bug with default help menu (Thanks, Bernd! This one was just in time!)
//
// Revision 1.65  1997/10/24 16:58:55  ettrich
// Matthias: bugfixes for session management.
//
// Revision 1.64  1997/10/22 20:42:52  kalle
// Help menu works as advertised
//
// Revision 1.63  1997/10/21 20:44:41  kulow
// removed all NULLs and replaced it with 0L or "".
// There are some left in mediatool, but this is not C++
//
// Revision 1.62  1997/10/17 15:46:22  stefan
// Moved the include of stdlib.h -- otherwise gcc-2.7.2.1 has an internal
// compiler bug. I know - I should upgrade gcc, but for all the
// poor folks that still have the old one ;-)
//
// Revision 1.61  1997/10/17 13:30:16  ettrich
// Matthias: registerTopWidget/unregisterTopWidget are obsolete and empty now.
//           Introduced new registration model
//
// Revision 1.60  1997/10/16 11:35:24  kulow
// readded my yesterday bugfixes. I hope, I have not forgotten one.
// I'm not sure, why this have been removed, but I'm sure, they are
// needed.
//
// Revision 1.59  1997/10/16 11:14:27  torben
// Kalle: Copyright headers
// kdoctoolbar removed
//
// Revision 1.57  1997/10/14 13:31:57  kulow
// removed one more default value from the implementation
//
// Revision 1.56  1997/10/13 14:31:03  ettrich

//
// Revision 1.55  1997/10/13 11:00:04  ettrich
// Matthias: fix to generation of SM command
//
// Revision 1.54  1997/10/12 14:36:34  kalle
// KApplication::tempSaveName() and KApplication::checkRecoverFile()
// now implemented as documented.
// The change in kapp.h is only in the documentation and thus *-compatible.
//
// Revision 1.53  1997/10/11 22:39:27  ettrich
