The CTk Toolkit

by Martin Andrews
andrewm@ccfadm.eeg.ccf.org

@(#) $Id: ctk.shar,v 1.50 1996/01/15 14:47:16 andrewm Exp andrewm $

1. Introduction
----------------

This directory contains the sources for CTk, a curses port of John
Ousterhout's Tk toolkit for X11.  The information here corresponds to
CTk 4.0.  CTk 4.0 is based on Tk 4.0p3. Like Tk 4.0p3, it is designed
to work with Tcl 7.4p3 and may not work with other releases of Tcl.

Using CTk, applications with a modern GUI-ish interface can be created
for character terminals.  These same applications, without modification,
can provide a real GUI interface by using Tk.  Thus, sites with an
embedded base of character terminals (and a small capital budget) can
smoothly migrate to GUI applications.

2. Documentation
----------------

There is a man page for cwish (cwish(1)) explaining execution options
for the CTk shell.  For script writing, the Tk Documentation, along with the
list of differences in section 5 of this document should be enough to get
started.

3. Compiling and installing CTk
-------------------------------

CTk requires TCL and a System V curses package (CTk will build
with BSD curses but has at least one display glitch and many
missing features - see porting.notes for more information).
Unlike Tk, you do not need the source for Tcl to build CTk.
Only the Tcl 7.4 library and include file (tcl.h) are necessary.
If your system does not have a System V compatible curses,
there is a free version, ncurses, available in GNU archives
(for instance ftp://prep.ai.mit.edu/pub/gnu).

CTk builds cleanly on the three systems I have easy access to:

    486 PC running Linux 1.1.54 using gcc 2.58 and ncurses 1.8.5

    HP 9000/835 running HP-UX 9.04 using optional ANSI C compiler and
    ncurses 1.8.6 or using K&R C compiler and hp curses (old system V,
    not very pretty)

    Sun 4c running Sun OS 4.13 using System V compiler (/usr/5bin/cc)
    and System V curses

Perform the following steps to compile and install CTk:

    (a) Type "./configure" in this directory.  This runs a configuration
	script created by GNU autoconf, which configures CTk for your
	system and creates a Makefile.  If you are using ncurses, and
	the library is named "libncurses" instead of "libcurses" give
	the "-with-ncurses" option to configure.  Also, if Tcl or curses
	are not installed in the standard search path, you can use
	"-with-libdirs=" and "-with-incdirs=" to add directories to
	the library and header search path, respectively (use the
	directives once, the argument can be a list of space separated
	directories).  For more details on using configure, check out
	the autoconf documentation (not included here).

    (b) Type "make".  This will create a library archive called "libctk.a"
	and an interpreter application called "cwish" that allows you to type
	Tcl commands interactively or execute script files.

    (c) If the make fails then you'll have to personalize the Makefile
        for your site or possibly modify the distribution in other ways.
	First check the file "porting.notes" to see if there are hints
	for compiling on your system.  If you need to modify Makefile,
	there are comments at the beginning of it that describe the things
	you might want to change and how to change them.
	
    (d) Type "make install" to install CTk's binaries and script files in
        standard places.  In the default configuration, information will
	be installed in /usr/local so you'll need write permission on
	this directory.  If you'd like to use a default installation
	directory, you can change the "exec_prefix" and "prefix" definitions
	in the Makefile.

    (e) At this point you can play with Tcl by invoking the "cwish"
	program and typing Tcl commands.  However, if you haven't installed
	CTk then you'll first need to set your CTK_LIBRARY environment
	variable to hold the full path name of the "library" subdirectory.

I am interested in receiving information on changes required to
build CTk on your platform.

4. Test suite
-------------

Next release.  (Really.)

5. Getting started
------------------

It is now easy to run cwish interactively.  If you have not
installed cwish set the CTK_LIBRARY environment variable to
the path of the library directory, then try:

    cwish

This will start cwish, and then pop-up a command dialog window where
you can enter TCL commands.  You can bring up this dialog at any time
by pressing <Control-C>.

You can also try out a simple demo of the cwish widgets with:

    cwish library/demos/stuff

There are other demos in the library/demos directory including a
crude port of the Tk widget demo (warning it is easy for the focus
to get lost - if so press Ctrl+C to get the command dialog and
type "exit" there).

Key bindings are very nearly the same as for Tk (which is very nearly
the same as Motif).  This may be unfamiliar to people used to common
Unix curses applications (elm, lynx, ..).  I decided to stick with the
Tk binding for two reasons:

1)  Less confusion for users that switch between Tk and CTk
    versions of an application.

2)  Easier to incorporate updates from Tk.

Here is a quick summary of the key bindings for those unfamiliar
with Motif (or Microsoft Windows):

    <Space> activates/selects a widget
    <Tab> moves focus to next the widget
    <Shift-Tab> moves focus to the prior widget
    <Return> activates the default button in a dialog
    Arrow keys move the cursor within a widget
    <F10> moves focus to the first menu
    <Escape> closes a menu without making a selection

Your terminal or terminfo entry may not support all the keys (like
<Shift-Tab>).  See README.TERM for tips on configuring terminfo
entries for CTk.

6. Summary of differences between CTk 4.0b1 and Tk 4.0
--------------------------------------------------------

The following commands are not available in CTk:

    canvas
    clipboard
    message
    image
    scale
    selection
    send

The wm command is severely crippled.

None of the widgets support the scan method.

The text widget does not support tag bindings: "text tag bind".

The text widget does not support embedded windows "text window".

The -tearoff option for menu widgets can create a tearoff entry,
but the entry doesn't work (and I don't know if there is any point
in making it work).

Many configuration options (like -background and -foreground) cannot
be modified.  Attempts to set the unsupported options will silently
be ignored.  Querying the options with cget will return a fixed
?reasonable? value.  The unsupported options are:

    -activebackground
    -activeborderwidth
    -activerelief
    -background
    -bg
    -bitmap
    -borderwidth (supported by widgets, not by text tags)
    -colormap
    -cursor
    -disabledforeground
    -exportselection
    -fg
    -font
    -foreground
    -highlightcolor
    -highlightbackground
    -highlightthickness
    -image
    -insertbackground
    -insertborderwidth
    -insertofftime
    -insertontime
    -insertwidth
    -indicatoron
    -jump
    -relief
    -repeatdelay
    -repeatinterval
    -screen
    -selectbackground
    -selectborderwidth
    -selectcolor
    -selectforeground
    -selectimage
    -setgrid
    -tearoff
    -troughcolor
    -visual

And a lot more I forgot to mention.

7. Support and bug fixes
------------------------

Send bug reports and suggestions for improvements to:

    Martin Andrews
    andrewm@ccfadm.eeg.ccf.org

When reporting bugs, please provide a short cwish script that I can
use to reproduce the bug.  Make sure that the script runs with a
bare-bones cwish and doesn't depend on any extensions.  Also, please
include three additional pieces of information with the script:

    (a) how do I use the script to make the problem happen (e.g.
	what keys do you press, in what order)?
    (b) what happens when you do these things (presumably this is
        undesirable)?
    (c) what did you expect to happen instead?

For general problems with using Tk or Tcl, try posting to the
comp.lang.tcl Usenet newsgroup.

8. Release organization
---------------------------

Each CTk release is identified by two numbers separated by a dot, e.g.
3.2 or 3.3.  These numbers match the release number of the corresponding
Tk release.  Suffixes for alpha, beta, and patch releases (aX, bX, and pX
respectively) are numbered independent of Tk.

README.TERM
		    Terminfo Notes for the CTk Toolkit

This file contains hints for setting up terminfo entries for use with CTk.
It assumes the reader already understands how to write terminfo entries
(as much as anyone really understands this black art).  See the manual
page, terminfo(4), for general information on terminfo.

@(#) $Id: ctk.shar,v 1.50 1996/01/15 14:47:16 andrewm Exp andrewm $

Special Keys
------------

CTk tries to map the curses key codes to X-11 keycodes and hence to
Tk key names.  This mapping (in reverse) is shown below:

	Tk Name		Capname
	-------		-------
	BackSpace	kbs
	Begin		kbeg
	Cancel		kcan
	Clear		kclr
	Delete		kdch1
	Shift-Delete	kdl1
	Down		kcud1
	End		kend
	End		kfnd
	Control-End	kll
	Execute		kcmd
	F1		kf1
	F10		kf10
	F2		kf2
	F3		kf3
	F4		kf4
	F5		kf5
	F6		kf6
	F7		kf7
	F8		kf8
	F9		kf9
	Help		khlp
	Home		khome
	Insert		kich1
	Insert		kmir
	Shift-Insert	kil1
	Left		kcub1
	Menu		kopt
	Next		knp
	Pause		kspd
	Print		kprt
	Prior		kpp
	Redo		krdo
	Return		kent
	Right		kcuf1
	Select		kslt
	Tab		knxt
	Shift-Tab	kcbt
	Shift-Tab	kprv
	Undo		kund
	Up		kcuu1

In addition the following special keys can be generated by control
keys (therefore, you cannot receive a <Control-h> event):

	Tk Name		Control Key
	-------		-----------
	Backspace	<Control-H>
	Tab		<Control-I>
	Return		<Control-M>

Other control keys are passed as the appropriate key press with the
Control Modifier set.


Display Attributes
------------------

CTk uses the following terminfo display attributes: standout (the focus),
reverse (selected), underline (entry widgets), bold (button widgets),
and dim (inactive widgets).  CTk does not try to use combinations of
attributes (for example: bold-underline) so you do not need to
define the "sgr" capability.  If an attribute is not defined the item
is displayed as plain text.

If possible, each of the attributes should have a unique appearance
(standout = bold is very bad, because a button will not change appearance
when it has the focus).  Following the ncurses recommendation that
standout should "represent a good, high contrast, easy-on-the-eyes,
format" I define standout as reverse-dim.


Custom CTk Terminfo Entries
---------------------------

If you find that the terminal definition you want for CTk conflicts with
what you want normally.  You can create the CTk entry with an alternate
name (like vt100-tk) and then set the environment variable CTK_TERM
to this alternate entry.  CTK_TERM is by CTk in preference to the TERM
environment variable.

This file contains a list of bugs to fix and minor feature changes
needed in the Tk toolkit.  The list is ordered by the time when the
idea for the change first arose;  no priority should be inferred from
the order.

@(#) $Id: ctk.shar,v 1.50 1996/01/15 14:47:16 andrewm Exp andrewm $

1. Add option to turn off background fill on window visibility
changes (only frame and toplevel widgets need it).

2. Implement embedded windows for text widget.

3. Fix cursor display in text widgets (occasionally off the right edge
of the screen).

5. Implement remaining methods of wm command.

7.  Add bindings for entry and text selection (ones that can be
generated from a character terminal).

8. Support color?  Handy for PC consoles with too little oomph for X.
(And for people with VT320 terminals - but does anyone really have
them?)

9. Add message and scale widgets.

10. Add do-nothing variants of all remaining unsupported Tk commands?

11. Implement remaining text display attributes (only underline works) -
would some way of mapping the attributes to available terminal attributes.

18. Extend command dialog to include menu of complete window management
operations.

23. Modify tkFont.c so that display of ISO-??? characters is reasonable
(map characters with diacritics to characters without).

24. Can't use -geometry option because "wm" is defined in time - either
move forward Tk_AppInit, or make "wm" a C command.

25. Add "ctk exec" command to execute an interactive command on win's
display. (e.g. "ctk exec . vi myfile")

26. Call delscreen() after endwin() on systems that define delscreen().
(SysVR4 curses seem to need it to free up resources - but HP curses
doesn't define delscreen())

Changes made since ctk8.0 was initially released are summarized below:

Changed the 'configure' command to recognize tcl8.0
Changed the Makefile.in to build cwish$(VERSION) instead of cwish

This file summarizes all changes made to CTk since version 4.0a1 was
released on March 12, 1995.  Changes that aren't backward compatible
are marked specially.

# Revision 1.48  1995/12/21  19:31:05  andrewm
# Added "ctk redraw" command.
#
# Revision 1.47  1995/12/20  22:22:00  andrewm
# (bug fix) made ctkDisplay.c 8-bit clean (wasn't casting char
# to unsigned char) - thanks Jan Vlcek.
#
# Revision 1.46  1995/12/20  21:13:04  andrewm
# Incorporate changes from Tk4.0 patch 3 (tk4.0p3).
#
# Revision 1.45  1995/12/20  16:28:09  andrewm
# Incorporate changes from tk4.0 patch 2.
#
# Revision 1.44  1995/12/04  19:57:27  andrewm
# (bug fix) tkListbox.c - display cursor even when active row is not
# visible (put it in the top left corner).
#
# (feature change) tkListbox.c - no longer display "*" next to selected
# items - rely on display attribute instead.
#
# (feature change) listbox.tcl - Left and Right now scroll by pages
# instead of characters.
#
# Revision 1.43  1995/12/04  19:19:52  andrewm
# bug fix - forgot to change var name when pasting code into tk_popup.
#
# Revision 1.42  1995/11/19  17:07:16  andrewm
# Incorporate changes from Tk4.0 patch 1.
#
# Revision 1.41  1995/11/17  15:35:49  andrewm
# Drop use of A_INVIS in ctkDisplay.c - those styles should never be
# drawn anyway - and most terms don't support it (and it screws up
# out terminal session manager).
#
# Revision 1.40  1995/11/06  13:31:19  andrewm
# Change TK_PATCH_LEVEL to CTK_PATCH_LEVEL and tcl variable tk_patchLevel
# with ctk_patchLevel.  Only version numbers track between Tk and CTk -
# and this make for an easy way to tell when you are using CTk.
#
# Add Tk_RestackWindow() and pull stacking arguments out of Tk_Map() -
# now raise and lower commands use Tk_RestackWindow instead of Ctk_Map
# (because they should not map unmapped windows).
#
# The CTk menu now underlines the X in Exit (not the E).
#
# Revision 1.39  1995/08/31  19:48:54  andrewm
# Make sure that all uses of ckalloc/ckfree are with (char *) pointers
# (cast when necessary).
#
# Install as version 4.0 - don't need a different library for each patch.
#
# Revision 1.38  1995/08/25  20:38:47  andrewm
# bug fix - finally track down glitch that caused some slaves to not
# be mapped - backwards logic in tkGeometry.c.
#
# aesthetics - tk_dialog now uses a simpler appearance for the default
# button (add [] to label instead of an enclosing frame).
#
# Revision 1.37  1995/08/25  18:41:19  andrewm
# Change tkFindMenu to that it only finds menubuttons that do not
# have an indicator (otherwise the F10 key will fire menus of
# options buttons).
#
# Add exit to Ctk menu.
#
# Revision 1.36  1995/08/24  17:50:35  andrewm
# Add compatibilty info to tk.h to simplify porting of Tk extensions
# to ctk (BLT table was easy!).
#
# Revision 1.35  1995/08/22  19:48:01  andrewm
# Fix bug when destroying all windows from within a command from
# an event binding (could core dump).
#
# Revision 1.34  1995/08/22  17:31:37  andrewm
# Add ability for multi-column (wrapped) menus.
#
# Change menu button indicator to "^" (was "=").
#
# Revision 1.33  1995/08/21  21:39:57  andrewm
# More logical key fixes - no longer bind directly to "space" - instead
# bind to Select, and remap space to Select.
#
# Make Return a do-what-I-want key instead of the dialog closure key
# (which is now Execute).
#
# Curses Enter/Send key now maps to KP_Enter, not Return.
#
# Revision 1.32  1995/08/21  20:47:50  andrewm
# Remove root window from name table after creating "." window -
# otherwise user can reference the root, which can cause core dumps.
#
# Change bindings to use logical key names only - then central
# ctk.tcl binds other keys to generate logical key events.
#
# Add ctk_event command (ala testevent).
#
# Revision 1.31  1995/08/21  14:52:49  andrewm
# Fix foolish change to text/entry insertion - back to Insert procefdure
# returning a boolean.
#
# Revision 1.30  1995/08/21  13:30:49  andrewm
# Pull out the menu traversal by matching first label character - decide
# it better belongs in a library.
#
# Revision 1.29  1995/08/18  21:58:02  andrewm
# Modify bindings within menu to activate entries by pressing the first
# letter of their label.
#
# Revision 1.28  1995/08/18  19:56:34  andrewm
# Rewite the tkEntryInsert and tkEntrySeeInsert procedures in C.
# Not sure if the payoff is worth it this time.
#
# Revision 1.27  1995/08/18  14:15:35  andrewm
# Rewrite the tk_focusNext and tk_focusPrev procedures in C, because
# their overhead was annoying on loaded server machines - particularly
# if you overshoot a widget and have not Shift-Tab on your terminal!

# toplevel when focus is lost (focus window destroyed).
#
# Revision 1.16  1995/07/11  20:54:02  andrewm
# (bug fix) wm.tcl - fix several references to "winfo" that should be "info".
#
# Revision 1.15  1995/07/11  20:33:19  andrewm

# each top-level remembers the last child to have the focus.
#
# Revision 1.14  1995/07/11  19:25:12  andrewm

# core dump).
#
# Revision 1.7  1995/06/23  13:26:46  andrewm
# (feature change) frames/toplevels no longer highlight when they
# have the focus (it was a waste).
#
# (feature change) menus default to "-tearoff 0"  (should remove support
# for -tearoff, it has no practical use in ctk - the torn off menu
# would be less convenient than the original).
#
# Revision 1.6  1995/06/11  22:44:11  andrewm
# (bug fix) fix bug where bottom of text widget would not be cleared

# with shifted alpha characters.
#
# Revision 1.3  1995/06/11  14:36:39  andrewm
# Display focus/insertion point using terminal cursor (instead of inverted
# text) - faster and better appearance.
#
# Revision 1.2  1995/05/28  14:55:30  andrewm
# (new feature) sweeping changes, add tkOption.c, to support
# "option" command.

5/5/95 (bug fix) Modify command.tcl so that commands are evaluated
in a global context.

--- ctk4.0a2 Released ---

5/4/95 (bug fix) Modify configure.in to check for gettimeofday() -
if it doesn't exist add the socket library (for SCO).

5/4/95 (new feature) Modify ctkDisplay.c so that the environment
variable CTK_TERM can override the TERM environment variable (to
allow terminal definitions customized for CTk).

5/3/95 (new feature) Add ctkDialog for interactive cwish sessions.  Modify
tkMain.c so that it calls ctkDialog instead of reading commands from
stdin when the user doesn't redirect the display.

5/3/95 (feature change) Modify tkCmds.c so that widget bindings come before
class bindings.  (Patch from Dr. Ousterhout.)
*** POTENTIAL INCOMPATIBILITY ***

4/22/95 (bug fix) Modify tkFont.c and and tkTextDisp.c so that cursor
is drawn in entry and text widgets when the insertion point is in front
of a tab character.

4/22/95 (new feature) Add scrollbar.tcl for scrollbar keyboard bindings and
modify tkScrollbar.c to highlight when the scrollbar has the focus.
(But scrollbars default to "-takefocus 0".)

4/22/95 (feature change) Modify tkMain.c and tkWindow.c to change
the environment variable that specifies display terminal to CTK_DISPLAY
(CWISH_DISPLAY will still work but it is deprecated and support for it
will eventually be removed).
*** POTENTIAL INCOMPATIBILITY ***

4/22/95 (feature change) Modify listbox.tcl so that PageUp and PageDown
key bindings change the active element.

4/6/95 (many fixes & features) Incorporate tk4.0b3 changes.
*** POTENTIAL INCOMPATIBILITY ***

3/23/95 (bug fix) Modified tkWindow so that Tk_CreateMainWindow()
will not pass a null argument (screen) to the "frame" command -
this was the real cause of the NULL dereference I tried to fix on
3/20/95 - undo that first fix.

3/21/95 (new feature) Modify tkFrame.c, tkListbox.c, tkText.c, and
tkTextDisp.c to highlight the border of frame, listbox, and text
widgets when they have the focus.

3/20/95 (bug fix) Modified tkConfig.c so that DoConfig() wouldn't
dereference a NULL value (thanks Peter da Silva).

3/20/95 (bug fix) Modified tkWindow.c to destroy top-level children of
main window (missed them before, and therefore wouldn't close display).

3/15/95 (new feature) Modify ctkDisplay.c to put terminals in raw mode
so that interrupt, quit, etc are passed as keys instead of generating
signals.

3/13/95 (bug fix) Modified tkTextMark.c to no longer dump core when the
insert mark wraps across lines (put back InsertUndisplayProc() - why
I removed it in the first place I have no idea).

9/20/96 (port) Port ctk to tcl7.6: event handling (remove from ctk, call
tcl's), channel handling. Should be better to reorganize code and
merge in tk4.2 as another platform (Curses) -- Juanjo <jjciarla@raiz.uncu.edu.ar>

7/16/97 (port) Port ctk to tcl8.0: change ctk.tcl to expect a higher version of tcl/tk.
Still needs "grid" and a number of other enhancements. Michael (mschwart@nyx.net)

# This file is a shell script that caches the results of configure
# tests run on this system so they can be shared between configure
# scripts and configure runs.  It is not useful on other systems.
# If it contains results you don't want to keep, you may remove or edit it.
#
# By default, configure uses ./config.cache as the cache file,
# creating it if it does not exist already.  You can give configure
# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.
