.SH NAME
\fPxvkbd\fP - virtual keyboard for X window system

.SH DESCRIPTION
.PP
\fIxvkbd\fP is a virtual (graphical) keyboard program for X Window System
which provides a facility to enter characters onto other clients (software)
by clicking on a keyboard displayed on the screen.
This may be used for systems without a hardware keyboard
such as kiosk terminals or handheld devices.
This program also has a facility to send characters
specified as the command line option to another client.
.PP
The standard keyboard layout is based on the traditional US layout,
but some other keyboard layout (see "Screenshot")
are also supported.
The default window size may be too large for systems with small screen,
but it can be configured to use smaller space (220x90 pixels, for example).
For details,
see also "Screenshot"
and "How to Customize \fIxvkbd\fP" below,
and resouce files in the distribution.
.PP
\fIxvkbd\fP version 2.1 and later support word completion
and \fIxvkbd\fP version 4.0 and later will now learns the used words for word completion
,
which may make it easier to enter long words with \fIxvkbd\fP.
.PP
\fIIMPORTANT NOTE:\fP
When invoking \fIxvkbd\fP from display managers such as XDM, GDM, etc.,
always use \fIxvkbd\fP with \fB-secure\fP option
or you will have serious security risk.

.SH "Environment"
\fIxvkbd\fP will work on X11R5 or X11R6.
It is tested on \fIredhat Linux\fP and \fISolaris\fP,
and it will work also on most UNIX-like systems.
.PP
This program uses \fIXaw\fP (use of \fIXaw3d\fP is recommended) 
and no special library is required.

.SH "Operation"

.SH "    Input Keys"
When \fIxvkbd\fP is started, the image of a keyboard 
will be displayed on the screen.
Clicking any key on the \fIxvkbd\fP window will send the character
to the focused window
as if the key had been actually typed with the hardware keyboard.
.PP
If you want to input upper-case alphabets
or other characters on the upper position on the keyboard,
you should click the key after selecting \fIShift\fP by clicking it,
or click the key with mouse button 3 (maybe right button) or mouse button 4.
In the similar manner, if you want to input \fIControl\fPed characters,
you should click the key after clicking \fIControl\fP,
or click the key with mouse button 2 (maybe middle button).
\fIAlt\fP and \fIMeta\fP can be used in the similar manner with \fIControl\fP,
but there are no shortcuts with mouse buttons.

.SH "    ``Quick Modifiers''"
\fIxvkbd\fP 2.5 and later support another way to input characters
with modifiers such as \fIShift\fP, \fIControl\fP, \fIAltGr\fP, etc.,
which may be useful especially for machines with touch panels such as PDAs
- we would call it \fI"Quick Modifiers"\fP.
.PP
\fIQuick Modifiers\fP can be enabled/disabled by the
``\fIEnable "Quick Modifiers?\fP'' entry on the
property panel.
If \fIQuick Modifiers\fP is enabled,
it will be activated by pressing a key on the \fIxvkbd\fP window,
move the pointer outside of the key,
and then release the mouse button or equivalent.
.PP
The direction of the pointer motion will select the modifier:
.sp
.in +4
.nf
  up        - Shift
  right     - AltGr
  right-up  - Shift AltGr
  left      - Control
  left-up   - Shift Control
  down      - Meta
  left-down - Alt
.fi
.sp
.in -4

.SH "    Setting Input Focus"
If you are using a window manager and clients
where you can set input focus by clicking mouse button on the window 
(and you don't have to keep pointer in the window after that),
you can simply set input focus in the normal way
and then click keys on the \fIxvkbd\fP window 
- the character will be sent to the selected position.
.PP
If you are using a window manager or clients
where you must keep the pointer in the input field to input from the keyboard,
or if the input focus is switched to the \fIxvkbd\fP window
when you clicked on the key on the \fIxvkbd\fP window,
you must make \fIxvkbd\fP to set input focus explicitly
by clicking the \fIFocus\fP button on the \fIxvkbd\fP window
and then click on the input field.
This input focus can be cleared by clicking \fIFocus\fP button
with mouse button 3, or simply clicking \fIFocus\fP button twice.

.SH "    Word Completion"
Choosing ``\fIWord Completion...\fP'' in the main menu
will popup the \fIWord Completion\fP panel.
.PP
When you entered characters by clicked keys on the \fIxvkbd\fP window as usual
while the \fIWord Completion\fP panel open,
words started with the characters will be listed in the panel,
and you can enter the remaining characters of the selected word
by clicking one of the words in the list.
.PP
  When ``\fIIntegrate Completion Panel?\fP'' on the property panel is set on,
  completion panel will be displayed on the main window when required.
  .PP
The dictionary (list of words) file is \fB/usr/share/xvkbd/words.english\fP by default,
but it can be changed with \fIStatic Dictionary\fP on the property panel.
.PP
  In addition, \fIxvkbd\fP records the used words and those scores in \fB$HOME/.xvkbd.words\fP.
  
.SH "    Main Menu"

    Default: \fB/usr/share/xvkbd/words.english\fP
.TP 4
  \fIDynamic Dictionary Weight\fP
      This parameter controls "learning" of recently used words.
    When this value is set 0, \fIxvkbd\fP will not learn used words.
    With higher value setting, \fIxvkbd\fP will quickly
    learn the used words and effectively ignores frequency information
    in the Static Dictionary.
    Default: 1.
.TP 4

Display version information and exit.
.TP 4
.B "-xsendevent"
Make \fIxvkbd\fP to use \fIXSendEvent()\fP to simulate keyboard events,
as it was in \fIxvkbd\fP version 1.0.
\fIxvkbd\fP version 1.1 and later will try to use XTEST extension instead
in the default configuration.
Because it is not unusual applications to ignore keyboard events
generated with \fB-xsendevent\fP,
you shouldn't use \fB-xsendevent\fP option unless it is really required.
.sp 0.5
If XTEST extension is not supported by the X server,
\fIxvkbd\fP will automatically switch to this mode.
.sp 0.5
Resource `\fBxvkbd.xtest: false\fP' has the same function.
.TP 4
.B "-no-sync"

.SH "Install"

.SH "    xmkmf"
.IP "  o " 4
\fIuntar\fP the source in a directory,
and move to the directory
.IP "  o " 4
If you wish to use genuine \fIXaw\fP instead of \fIXaw3d\fP,
edit \fBImakefile\fP and remove (or comment-out) `\fB#define XAW3D\fP'.
.sp 0.5
When you are installing \fIxvkbd\fP (for example) in very old systems,
you may also want to remove `\fB#define XTEST\fP' and `\fB#define I18N\fP'
to disable XTEST and internationalization facility respectively.
.IP "  o " 4
Run: \fBxmkmf; make install install.man\fP

.SH "    configure"
Alternatively, maybe you can:

.SH "Customization"

.SH "    How to Customize \fIxvkbd\fP"
Some degree of customization of \fIxvkbd\fP is possible
by setting resources.
Some resources are already described above,
and resources to customizing keyboard layout are described below.
.PP
To set resources, you can:
.IP "  o " 4
put them in your \fB$HOME/.Xdefaults\fP file, or
.IP "  o " 4
load them via \fIxrdb\fP(1), or
.IP "  o " 4
set the filename to the \fB$XENVIRONMENT\fP environment variable, or
.IP "  o " 4
put them in application default directory as `\fBXVkbd-\fP\fIsuffix\fP'
and set resource ``\fBxvkbd.customization: -\fP\fIsuffix\fP'', or
.IP "  o " 4
put them in application default directory as \fBXVkbd\fP.
.PP
Here, \fIapplication default directory\fP can be either of:
.IP "  o " 4
directories specified with \fB$XUSERFILESEACHPATH\fP,
\fB$XAPPLRESDIR\fP or else \fB$HOME\fP environment variable
.IP "  o " 4
system's application default directory specified with
\fB$XFILESEACHPATH\fP environment variable,
or else the directory specified when compiling the X
(e.g., \fB/usr/lib/X11/app-defaults\fP)
.PP
When the application default file is to be stored
in the system's application default directory,
the file must contain ``\fB#include "XVkbd-common"\fP''
near top of the file.
.PP
\fIxvkbd\fP is distributed with some application default files,
and they will be installed in the system's application default directory.

.SH "    Making Window Small"
Size (and position) of \fIxvkbd\fP window can be set
by `\fBxvkbd.windowGeometry\fP' resource.
When making window small, you may need to choose the smaller font, too.
.sp
.in +4
.nf
  xvkbd.windowGeometry: 220x90
  xvkbd.compact: true
  xvkbd*Font: 6x12
.fi
.sp
.in -4
.PP
You may also want to set:
.sp
.in +4
.nf
  xvkbd.modalKeytop: true
.fi
.sp
.in -4
to display only the labels for the current shift state,
instead of trying to always display all of them in the small keytop.
.PP
See also \fBXVkbd-small.ad\fP in the \fIxvkbd\fP distribution.

.SH "    Removing Unwanted Keys"
Keys on \fIxvkbd\fP window can be removed by setting their width to 1.
The resource name of the keys that start with a capital letter
(and of the \fBspace\fP key) is the same as the key itself,
the others are of the form \fI<row>,<col>\fP (counting from zero).
.PP
To remove \fICompose\fP key and make \fIShift\fP key larger,
you can write:
.sp
.in +4
.nf
  xvkbd*Multi_key.width: 1
  xvkbd*Shift_R.width: 75
.fi
.sp
.in -4
.PP
To remove right \fIAlt\fP and \fIMeta\fP key,
you can write:
.sp
.in +4
.nf
  xvkbd*Alt_R.width: 1
  xvkbd*Meta_R.width: 1
.fi
.sp
.in -4

.SH "    Customizing Keyboard Layout"
Layout of keys on the \fIxvkbd\fP window can be customized
with following resources:
.TP 4
.B "xvkbd.NormalKeys"
list of keys available when neighter of \fIShift\fP and \fIAltGr\fP are selected
.TP 4
.B "xvkbd.ShiftKeys"
list of keys available when \fIShift\fP is selected
.TP 4
.B "xvkbd.AltgrKeys"
list of keys available when \fIAltGr\fP is selected
.TP 4
.B "xvkbd.ShiftAltgrKeys"
list of keys available when both \fIAltGr\fP and \fIShift\fP are selected
.TP 4
.B "xvkbd.KeyLabels"
list of labels displayed on the keys
.TP 4
.B "xvkbd.NormalKeyLabels"
list of labels displayed on the keys
  when neither of \fIShift\fP and \fIAltGr\fP are selected.
.TP 4
.B "xvkbd.ShiftKeyLabels"
list of labels displayed on the keys
  when \fIShift\fP is selected
.TP 4
.B "xvkbd.AltgrKeyLabels"
list of labels displayed on the keys
  when \fIAltGr\fP is selected
.TP 4
.B "xvkbd.ShiftAltgrKeyLabels"
list of labels displayed on the keys
  when both \fIAltGr\fP and \fIShift\fP are selected
.PP
Four resources to set labels on the keys
(\fBxvkbd.NormalKeyLabels\fP, \fBxvkbd.ShiftKeyLabels\fP,
\fBxvkbd.AltgrKeyLabels\fP and \fBxvkbd.ShiftAltgrKeyLabels\fP)
will be used instead of \fBxvkbd.KeyLabels\fP
when \fBxvkbd.modalKeytop\fP resoruce is set \fBtrue\fP.
.PP
In all of those resources, each keys are separated by spaces,
and rows of keys are terminated with `\fB \\n\\\fP'
(note that `\fB\\n\fP' must have space before it).
Please refer \fBXVkbd-german.ad\fP and \fBXVkbd-latin1.ad\fP
in the \fIxvkbd\fP distribution for more about these resources.
.PP
\fBXVkbd-german\fP and \fBXVkbd-latin1\fP will be installed
in the system's application default directory,
and setting the resource ``\fBxvkbd.customization: -german\fP''
will make \fIxvkbd\fP to use the German layout.
For another method to activate those settings, please refer
"How to Customize \fIxvkbd\fP" above.

.SH "    Assigning Text to Function Keys"
Text can be assigned to each function keys
(and, actually, to most other keys).
If text is assigned to the function key,
clicking on the key will send the assigned text
instead of the function key itself.
When pointer is on a key where text is assigned,
the text will be displayed near the key.
.PP
The setting will be read from a text file
which contains text for each function keys as:
.sp
.in +4
.nf
  F1 text for F1
  F2 text for F2
  s:F1 text for Shift-F1
  c:F1 text for Control-F1
  m:F1 text for Meta-F1
  a:F1 text for Alt-F1
  ...
.fi
.sp
.in -4
.PP
`\fBs:\fP', `\fBc:\fP', `\fBm:\fP' and `\fBa:\fP'
before the keys name indicates four modifiers
(\fIShift\fP, \fIControl\fP, \fIMeta\fP and \fIAlt\fP) respectively.
.PP
If the first character of the assigned string is `\fB!\fP',
the string will be used as command to be executed when the key is clicked.
To assign string starting with `\fB!\fP' or `\fB\\\fP',
put `\fB\\\fP' before the string.
.PP
The file is \fB$HOME/.xvkbd\fP in default,
and it can be changed by setting the filename
with \fBxvkbd.keyFile\fP resource.
.PP
For \fBF1\fP to \fBF12\fP with or without \fIShift\fP modifier,
it is possible to edit the assigned string on a panel popped up via
"\fIEdit Function Keys...\fP" in the main menu.

.SH "Miscellaneous Informations"

.SH "    Notes"
.IP "  o " 4
On \fIXFree86\fP, resolution switch with
\fICtrl + Alt + Keypad-Plus\fP and \fICtrl + Alt + Keypad-Minus\fP 
may be simulated.
However, \fICtrl + Alt + Backspace\fP will not be simulated.
.IP "  o " 4
\fIShift\fP is used to decide key to be sent
and it will not used to set modifier bit when sending the event.
You can use \fBxev\fP command to check what is actually sent.
.IP "  o " 4
If \fIAlt\fP or \fIMeta\fP is not defined as modifier,
the key can't be used as modifier.
You can use `\fBxmodmap -pm\fP' to check how modifiers are defined.
.IP "  o " 4
\fINum Lock\fP (and maybe other modifiers) on the physical keyboard
may not work correctly when \fIxvkbd\fP is in use.
