+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ * When input from the terminal is received, the receiveData() slot should be called with
+ * the data which has arrived. The emulation will process the data and update the
+ * screen image accordingly. The codec used to decode the incoming character stream
+ * into the unicode characters used internally can be specified using setCodec()
+ *
+ * The size of the screen image can be specified by calling setImageSize() with the
+ * desired number of lines and columns. When new lines are added, old content
+ * is moved into a history store, which can be set by calling setHistory().
+ *
+ * The screen image can be accessed by creating a ScreenWindow onto this emulation
+ * by calling createWindow(). Screen windows provide access to a section of the
+ * output. Each screen window covers the same number of lines and columns as the
+ * image size returned by imageSize(). The screen window can be moved up and down
+ * and provides transparent access to both the current on-screen image and the
+ * previous output. The screen windows emit an outputChanged signal
+ * when the section of the image they are looking at changes.
+ * Graphical views can then render the contents of a screen window, listening for notifications
+ * of output changes from the screen window which they are associated with and updating
+ * accordingly.
+ *
+ * The emulation also is also responsible for converting input from the connected views such
+ * as keypresses and mouse activity into a character string which can be sent
+ * to the terminal program. Key presses can be processed by calling the sendKeyEvent() slot,
+ * while mouse events can be processed using the sendMouseEvent() slot. When the character
+ * stream has been produced, the emulation will emit a sendData() signal with a pointer
+ * to the character buffer. This data should be fed to the standard input of the terminal
+ * process. The translation of key presses into an output character stream is performed
+ * using a lookup in a set of key bindings which map key sequences to output
+ * character sequences. The name of the key bindings set used can be specified using
+ * setKeyBindings()
+ *
+ * The emulation maintains certain state information which changes depending on the
+ * input received. The emulation can be reset back to its starting state by calling
+ * reset().
+ *
+ * The emulation also maintains an activity state, which specifies whether
+ * terminal is currently active ( when data is received ), normal
+ * ( when the terminal is idle or receiving user input ) or trying
+ * to alert the user ( also known as a "Bell" event ). The stateSet() signal
+ * is emitted whenever the activity state is set. This can be used to determine
+ * how long the emulation has been active/idle for and also respond to
+ * a 'bell' event in different ways.

+QTermWidget is an opensource project based on KDE4 Konsole application.
+The main goal of this project is to provide unicode-enabled, embeddable
+QT widget for using as a built-in console (or terminal emulation widget).
+
+Of course I`m aware about embedding abilities of original Konsole,
+but once I had Qt without KDE, and it was a serious obstacle.
+I decided not to rely on a chance. I cannot find any interesting related project,
+so I had to write it.
+
+The original Konsole`s code was rewritten entirely with QT4 only; also I have to
+include in the project some parts of code from kde core library. All code dealing
+with user interface parts and session managers was removed (maybe later I bring it
+back somehow), and the result is quite useful, I suppose.
+
+This library was compiled and tested on three linux systems,
+based on 2.4.32, 2.6.20, 2.6.23 kernels, x86 and amd64.
+Please inform about its behaviour on other systems.

+ \brief An image of characters with associated attributes.
+
+ The terminal emulation ( Emulation ) receives a serial stream of
+ characters from the program currently running in the terminal.
+ From this stream it creates an image of characters which is ultimately
+ rendered by the display widget ( TerminalDisplay ). Some types of emulation
+ may have more than one screen image.
+
+ getImage() is used to retrieve the currently visible image
+ which is then used by the display widget to draw the output from the
+ terminal.
+
+ The number of lines of output history which are kept in addition to the current
+ screen image depends on the history scroll being used to store the output.
+ The scroll is specified using setScroll()
+ The output history can be retrieved using writeToStream()
+
+ The screen image has a selection associated with it, specified using
+ setSelectionStart() and setSelectionEnd(). The selected text can be retrieved
+ using selectedText(). When getImage() is used to retrieve the the visible image,
+ characters which are part of the selection have their colours inverted.

+/* Incoming Bytes Event pipeline
+
+ This section deals with decoding the incoming character stream.
+ Decoding means here, that the stream is first separated into `tokens'
+ which are then mapped to a `meaning' provided as operations by the
+ `Screen' class or by the emulation class itself.
+
+ The pipeline proceeds as follows:
+
+ - Tokenizing the ESC codes (onReceiveChar)
+ - VT100 code page translation of plain characters (applyCharset)
+ - Interpretation of ESC codes (tau)
+
+ The escape codes and their meaning are described in the
+ technical reference of this program.
+*/
+
+// Tokens ------------------------------------------------------------------ --
+
+/*
+ Since the tokens are the central notion if this section, we've put them
+ in front. They provide the syntactical elements used to represent the
+ terminals operations as byte sequences.
+
+ They are encodes here into a single machine word, so that we can later
+ switch over them easily. Depending on the token itself, additional
+ argument variables are filled with parameter values.
+
+ The tokens are defined below:
+
+ - CHR - Printable characters (32..255 but DEL (=127))
+ - CTL - Control characters (0..31 but ESC (= 27), DEL)
+ - ESC - Escape codes of the form <ESC><CHR but `[]()+*#'>
+ - ESC_DE - Escape codes of the form <ESC><any of `()+*#%'> C
+ - CSI_PN - Escape codes of the form <ESC>'[' {Pn} ';' {Pn} C
+ - CSI_PS - Escape codes of the form <ESC>'[' {Pn} ';' ... C
+ - CSI_PR - Escape codes of the form <ESC>'[' '?' {Pn} ';' ... C
+ - CSI_PE - Escape codes of the form <ESC>'[' '!' {Pn} ';' ... C
+ - VT52 - VT52 escape codes
+ - <ESC><Chr>
+ - <ESC>'Y'{Pc}{Pc}
+ - XTE_HA - Xterm hacks <ESC>`]' {Pn} `;' {Text} <BEL>
+ note that this is handled differently
+
+ The last two forms allow list of arguments. Since the elements of
+ the lists are treated individually the same way, they are passed
+ as individual tokens to the interpretation. Further, because the
+ meaning of the parameters are names (althought represented as numbers),
+ they are includes within the token ('N').

+/**
+ * @obsolete Use KProcess and KPtyProcess instead.
+ *
+ * Child process invocation, monitoring and control.
+ * This class works only in the application's main thread.
+ *
+ * <b>General usage and features:</b>\n
+ *
+ * This class allows a KDE application to start child processes without having
+ * to worry about UN*X signal handling issues and zombie process reaping.
+ *
+ * @see K3ProcIO
+ *
+ * Basically, this class distinguishes three different ways of running
+ * child processes:
+ *
+ * @li DontCare -- The child process is invoked and both the child
+ * process and the parent process continue concurrently.
+ *
+ * The process is started in an own session (see setsid(2)).
+ *
+ * @li NotifyOnExit -- The child process is invoked and both the
+ * child and the parent process run concurrently.
+ *
+ * When the child process exits, the K3Process instance
+ * corresponding to it emits the Qt signal processExited().
+ * Since this signal is @em not emitted from within a UN*X
+ * signal handler, arbitrary function calls can be made.
+ *
+ * Be aware: When the K3Process object gets destructed, the child
+ * process will be killed if it is still running!
+ * This means in particular, that it usually makes no sense to use
+ * a K3Process on the stack with NotifyOnExit.
+ *
+ * @li OwnGroup -- like NotifyOnExit, but the child process is started
+ * in an own process group (and an own session, FWIW). The behavior of
+ * kill() changes to killing the whole process group - this makes
+ * this mode useful for implementing primitive job management. It can be
+ * used to work around broken wrapper scripts that don't propagate signals
+ * to the "real" program. However, use this with care, as you disturb the
+ * shell's job management if your program is started from the command line.
+ *
+ * @li Block -- The child process starts and the parent process
+ * is suspended until the child process exits. (@em Really not recommended
+ * for programs with a GUI.)
+ * In this mode the parent can read the child's output, but can't send it any
+ * input.
+ *
+ * K3Process also provides several functions for determining the exit status
+ * and the pid of the child process it represents.
+ *
+ * Furthermore it is possible to supply command-line arguments to the process
+ * in a clean fashion (no null-terminated stringlists and such...)
+ *
+ * A small usage example:
+ * \code
+ * K3Process *proc = new K3Process;
+ *
+ * *proc << "my_executable";
+ * *proc << "These" << "are" << "the" << "command" << "line" << "args";
+ * QApplication::connect(proc, SIGNAL(processExited(K3Process *)),
+ * pointer_to_my_object, SLOT(my_objects_slot(K3Process *)));
+ * proc->start();
+ * \endcode
+ *
+ * This will start "my_executable" with the commandline arguments "These"...
+ *
+ * When the child process exits, the slot will be invoked.
+ *
+ * <b>Communication with the child process:</b>\n
+ *
+ * K3Process supports communication with the child process through
+ * stdin/stdout/stderr.
+ *
+ * The following functions are provided for getting data from the child
+ * process or sending data to the child's stdin (For more information,
+ * have a look at the documentation of each function):
+ *
+ * @li writeStdin()
+ * -- Transmit data to the child process' stdin. When all data was sent, the
+ * signal wroteStdin() is emitted.
+ *
+ * @li When data arrives at stdout or stderr, the signal receivedStdout()
+ * resp. receivedStderr() is emitted.
+ *
+ * @li You can shut down individual communication channels with
+ * closeStdin(), closeStdout(), and closeStderr(), resp.
+ *
