# tkx11vnc v0.2
# This is a simple frontend to x11vnc. It uses the remote control
# and query features (-remote/-query aka -R/-Q) to interact with it.
# It is just a quick-n-dirty hack (it parses -help output, etc), but
# it could be of use playing with or learning about the (way too) many
# parameters x11vnc has.
#
# It can be used to interact with a running x11vnc (see the x11vnc
# -gui option), or to set the parameters and then start up x11vnc.
#
#
# Below is a simple picture of how the gui should be laid out and how
# the menus should be organized. Most menu items correspond to remote
# control commands. A trailing ":" after the item name means it is a string
# to be set rather than a boolean that can be toggled (e.g. the entry
# box must be used).
#
# Some tweak options may be set in the prefix "=" string.
# A means it is an "Action" (not a true variable)
# R means it is an action only valid in remote mode.
# S means it is an action only valid in startup mode.
# Q means it is an action worth querying after running.
# P means the string can be +/- appended/deleted (string may not
# be the same after the remote command)
# G means gui internal item
# F means can be set via file browse
# D means for simple gui
# -C:val1,... means it will be a checkbox (radio button)
# the "-" means no other options follow
# 0 means to skip the item.
# -- means add a separator

proc set_internal_help {} {
global helptext helpall
# set some internal item help here:
set helptext(start) "
Launch x11vnc with the settings you have prescribed in the gui.
The x11vnc process is started in an xterm window so you can see the
output, kill it, etc.
By viewing this help item, the command built so far will be displayed
in the gui text area. Have a look. If you Press start it will be shown
as well and you will be asked to confirm running it.
If you want to use a saved profile \"rc file\" you can do \"Misc -> rc\" and
select the file and simply start x11vnc using the rc file. Alternatively,
you could first use the \"Actions -> load-settings\" action to load in
an \"rc file\" and then press \"Actions -> start\" to start up x11vnc
based on those values.
"
set helptext(stop) "
The \"Actions -> stop\" action sends a signal to the running x11vnc
server indicating it should shutdown all connections and exit.
The GUI stays running in case you want to start a new x11vnc or attach
to another one. Use \"Actions -> Quit\" if you then want to have the
gui exit. Use \"Actions -> stop+quit\" to have both exit at once.
"
set helptext(show-start-cmd) "
Displays in the text area what the x11vnc start command (i.e. the command
run by \"Actions -> start\") looks like for the current values of the
settings. This can be done even in the attached state. Intended for
debugging the gui. The help item for \"Actions -> start\" gives the
same info.
If you want to load in a saved profile \"rc file\" use \"Misc -> rc\"
and select the file. \"Actions -> load-settings\" does a similar thing
with an rc-file, but reading the file and setting the gui variables to
its values.
"
set helptext(debug_gui) "
Set debug_gui to get more output printed in the text area.
"
set helptext(detach) "
No longer be associated with the x11vnc server. Switch to the
non-connected state. The x11vnc server keeps running: it does not exit.
You can either later reattach to it \"Actions -> attach\", or start
up a new x11vnc \"Actions -> start\", or exit \"Actions -> Quit\".
"
set helptext(attach) "
Attach to a running x11vnc server, if possible. Switches to connected
state if successful. Usually the channel used to attach is via the X
display (VNC_CONNECT rootwin property) being polled by the x11vnc server.
To change or set the X display to use do \"Displays -> display\".
Sometimes the \"-connect /path/to/filename\" is used as the communcation
channel. The running x11vnc has to know that \"/path/to/filename\"
is the communication channel (i.e. it is using the same -connect option).
"
set helptext(ping) "
Check if x11vnc still responds to \"ping\" remote command.
"
set helptext(update-all) "
Query the x11vnc server for the current values of all variables.
Populate the values into the gui's database.
Normally the gui will refresh this info every time it interacts with
the x11vnc server (including after a few minutes of inactivity), so one
doesn't need to use this action very often (unless something else is
changing the state of the x11vnc server, or new clients have connected,
etc).
"
set helptext(clear-all) "
Forget any variable settings either entered in by you or set at the
default. Basically sets everything to 0 or the string (unset).
This action is only available in \"startup\" mode, not when connected
to a running x11vnc server (in that case the variable settings reflect
the state of the running x11vnc). To detach from a running x11vnc
server use \"Actions -> detach\"; to completely stop the x11vnc server
use \"Actions -> stop\".
"
set helptext(defaults-all) "
Reset all variable settings to the default values. Basically sets
everything to the default queries \"x11vnc -QD var\" retrieved at startup.
This action is only available in \"startup\" mode, not when connected
to a running x11vnc server (in that case the variable settings reflect
the state of the running x11vnc). To detach from a running x11vnc
server use \"Actions -> detach\"; to completely stop the x11vnc server
use \"Actions -> stop\".
"
set helptext(load-settings) "
Read in the \"rc file\" you prescribe in the dialog and then set the
variables to those in the rc-file. Any variables not mentioned in the
rc-file are set to their default value.
You could then do \"Actions -> start\" to start x11vnc with these
parameters. Or you could make some further changes to variables
using the gui before starting x11vnc.
This action is only available in \"startup\" mode, not when connected
to a running x11vnc server (in that case the variable settings reflect
the state of the running x11vnc). To detach from a running x11vnc
server use \"Actions -> detach\"; to completely stop the x11vnc server
use \"Actions -> stop\".
"
set helptext(save-settings) "
Construct a ~/.x11vncrc file based on the current settings and
offer to save it in a file (default ~/.x11vncrc). If saved in a
file other than the default, you can access the profile by using
the \"-rc <filename>\" option when starting x11vnc.
If an rc file entry begins with \"#d\" that means the current
setting is at the Default value and so you probably want to leave
it commented out with the \"#\" character.
If an rc file entry begins with \"#?\" that means we think
you probably do not really want to force the value to this setting.
In either case, feel free to uncomment the line and/or change any
of the parameter values in the file.
"
set helptext(all-settings) "
Displays the gui's database of all of the x11vnc server's current
settings. Use \"Actions -> update-all\" or \"Control+R\" to
refresh this list if it ever gets out of sync.
"
set helptext(remote-cmd) "
Run a remote command (-R) or query (-Q) directly. Only a few
remote commands are not on a menu, but for those few you can
run the command directly this way. Just enter the command into
the Entry box when prompted. Use the prefix \"Q:\" to indicate
a -Q query. Examples: \"zero:20,20,100,100\", \"Q:ext_xfixes\"
"
set helptext(stop+quit) "
Send the stop command to the x11vnc server, then terminate the tkx11vnc gui.
"
set helptext(show-logfile) "
View the current contents of the logfile (if it exists and is accessible
by the gui process).
"
set helptext(tail-logfile) "
Run the tail(1) command with -f option on the logfile in an xterm.
(if it exists and is accessible by the gui process).
"
set helptext(Quit) "
Terminate the tkx11vnc gui. Any x11vnc server will be left running.
"
set helptext(current) "
Shows a menu of currently connected VNC clients on the x11vnc server.
Allows you to find more information about them, change their input
permissions, or disconnect them.
You will be prompted to confirm any disconnections.
"
set helptext(client) "
After selecting a VNC client from the \"Clients -> current\" menu,
you will be presented with a dialog that shows the information
about the VNC client.
You can choose to disconnect the client by clicking on the
\"Disconnect\" checkbox and pressing \"OK\". There will be a
confirmation dialog to doublecheck.
Alternatively, you can fine tune the VNC client's input permissions
by selecting any of the Keystrokes, Mouse-Motion, Button-Clicks, or
Clipboard-Input checkboxes and pressing \"OK\". This is like the
\"-input\" option but on a per-client basis.
To not change any aspects of the VNC client press \"Cancel\".
"
set helptext(solid_color) "
Set the -solid color value.
"
set helptext(xrandr_mode) "
Set the -xrandr mode value.
"
set helptext(unixpw_list) "
Set the -unixpw usernames list value.
"
set helptext(unixpw_nis_list) "
Set the -unixpw_nis usernames list value.
"
set helptext(stunnel_pem) "
Set the -stunnel pem filename value.
"
set helptext(ssl_pem) "
Set the -ssl pem filename value.
"
set helptext(wireframe_mode) "
Set the -wireframe mode string value.
"
set helptext(simple-gui) "
Toggle between menu items corresponding the most basic ones
and all possible settings. I.e. toggle between a simple gui
and one for power users.
"
set helptext(Tray) "
The tray/icon mode (started with \"x11vnc -gui tray ...\", etc.) presents
a small icon that indicates the status of the running x11vnc server.
Depending on your environment, this icon may be embedded in a system
tray or applet dock, or simply be a standalone window. \"-gui tray\"
will attempt to embed the icon in the system tray, while \"-gui icon\"
is for a standalone window. Use \"-gui tray=setpass\" (or icon=setpass)
to be prompted to set the session password at startup.
When the icon has a light background, that means no VNC viewers are
currently connected to the VNC display.
When the icon has a dark background (i.e. reverse-video), that means at
least one VNC viewer is connected to the VNC display.
Moving the mouse pointer over the icon will popup a \"status balloon\"
indicating the VNC display name and the names and info of any connected VNC
viewers. Press the middle mouse button if the balloon does not appear.
Clicking the left or right mouse button on the icon displays a menu
of actions:
Properties - Brings up the Properties dialog to set some basic
parameters. The full tkx11vnc GUI may be accessed
via the \"Advanced ...\" button. Press \"Help ...\"
in the Properties dialog for more info.
Help - Displays this help text.
New Client - Presents an entry box where you type in the name
of a computer that is running a VNC viewer in
\"listen\" mode (e.g. vncviewer -listen). For a
non-standard listening port use \"host:port\".
Pressing \"OK\" will initiate the reverse
connection. Use a blank hostname to skip it.
Disconnect - Shows a popup menu of connected clients. Click on
one to disconnect it, or click on \"All Clients\"
disconnect all clients.
Window View - Switch between the \"full\" gui (also known as
\"Advanced\"), \"icon\" mode (small icon window with
popups), or \"tray\" mode (small icon embedded in the
system tray). This is a shortcut for the action:
\"Properties -> Advanced -> Misc -> WindowView\".
Stop x11vnc - Directs the x11vnc server to disconnect all vncviewers
and then exit. The tray/icon GUI then exits as well.
Custom - If you have a \$HOME/.x11vnc.gui file each uncommented
line in it becomes an additional menu item for this
menu. The remote control command is run directly
via \"x11vnc -R <command>\", or if prefixed with
\"action:\" runs a gui internal action, or if \"sep\"
adds a separator. Set X11VNC_CUSTOM_GUI to use
a different filename. Example file contents:
scale:3/4
scale:1
scale_cursor:1
sep
action:all-settings
#debug_keyboard
sep
action:Quit
Termination:
If the x11vnc server stops for any reason, the tray/icon gui will exit.
If you delete the tray/icon (e.g. X out button), that is the same
as the \"Stop x11vnc\" action in the menu. (This will disconnect any
VNC viewer you are currently using to access the display since the
x11vnc server is terminated).
To terminate the tray/icon gui window but not the x11vnc server press
Control-C on the tray/icon window. You can also do this (and much
more) via Properties -> Advanced -> Actions -> Quit
"
set helptext(NewClient) "
New Client - Presents an entry box where you type in the name
of a computer that is running a VNC viewer in
\"listen\" mode (e.g. vncviewer -listen). For a
non-standard listening port use \"host:port\".
Pressing \"OK\" will initiate the reverse
connection. Use a blank hostname to skip it.
"
set helptext(Properties) "
The Properties dialog allows you to set some basic parameters of a
running x11vnc server. After modifying them press \"OK\" or \"Apply\"
to apply the changes, or press \"Cancel\" to skip applying them.
- \"Accept Connections\" toggles whether VNC viewers are allowed
to connect or not. It corresponds to the \"-R unlock\" and \"-R lock\"
remote-control commands.
- \"Ask for Confirmation\" toggles whether a popup menu will be presented
at the X display when a new VNC viewer attempts to connect. The person
sitting at the X display can choose to accept or reject the connection
or accept the connection in View-Only mode. It corresponds to the
\"-R accept:popup\" and \"-R accept:\" remote-control commands.
- \"All Clients ViewOnly\" toggles whether the entire VNC desktop is
view only. All clients will only be able to watch when this is set
(regardless of how they logged in). It corresponds to the
\"-R viewonly\" and \"-R noviewonly\" remote-control commands.
- \"Shared\" toggles whether multiple simultaneous connections are
allowed or not. It corresponds to the \"-R shared\" and \"-R noshared\"
remote-control commands.
- \"Password\" lets you set the session password viewers may use to gain full
access to the display. This will only work if x11vnc was started with
the -gui icon or -gui tray mode.
- \"ViewOnly Password\" lets you set the session password viewers may
use to gain view only access to the display. This will only work if
x11vnc was started with the -gui icon or -gui tray mode.
NOTE: These \"session\" passwords only last for the current x11vnc
session (they are not remembered, see the -storepasswd, -passwdfile,
and -rfbauth x11vnc options for using stored passwords).
If you set \"Password\" to the empty string that makes the \"View-Only
Password\" empty as well and removes the need for any password to log in.
If you set \"ViewOnly Password\" to the empty string that just removes
the ViewOnly log in aspect: \"Password\" is still required to log in.
- The \"Help ...\" button shows this help text.
- The \"Advanced ...\" button replaces the Properties dialog with the full
tkx11vnc GUI. All dynamic settings can be modified in the full GUI.
--------------------------------------------------------------------
Don't Lock Yourself Out:
If you are sitting at the physical X display you cannot get into too
much trouble setting the Properties dialog values.
However IF you are using a VNC Viewer to REMOTELY access the X display
some items in the Properties dialog can lock you out of further access:
\"Accept Connections\" if you disable this remotely, and
accidentally disconnect your VNC viewer then you will not be
able to reconnect.
\"Ask for Confirmation\" if you enable this only someone
sitting at the X display can confirm any new VNC connections.
Furthermore, any current VNC viewers will be blocked while
waiting for the confirmation (times out in 120 sec by default).
\"All Clients ViewOnly\" if you enable this remotely, well
you can no longer provide input to disable it.
If you do lock yourself out you could log in remotely and start up
a second x11vnc and connect to that one to try to fix things in the
first one.
Note that if there are two or more x11vnc's on the same display the
use of the GUI may be ill-behaved. Terminate the second x11vnc as
soon as you have fixed the setting in the first one. Use of a remote
control command, e.g. \"x11vnc -R noviewonly\" or \"x11vnc -R unlock\"
is a good way to avoid this problem.
"
set helptext(all) $helpall
set helptext(Misc-Tuning:) "
x11vnc has what seems like hundreds of tuning parameters! In this
sub-menu we place some lesser used ones. Most likely you'll want to
leave them at their default values, but you can try them out quickly
with the gui to see if they improve things.
"
set helptext(Passwords:) "
The items in this sub-menu pertain to setting passwords. Note that x11vnc
has two types of password files: RealVNC-style ones (you can create them
with x11vnc -storepasswd or other VNC utility program) you use these
via -rfbauth; and plain-text file passwords you use via -passwdfile.
Normally passwords cannot be changed by remote-control (e.g. the gui),
but for the case of the \"Icon\" and \"Tray\" modes this constraint has
been relaxed.
In neither the RealVNC-style nor the plain-text file cases should the
password files be readable by users you do not want to access the VNC
server. Contrary to popular belief, the RealVNC-style passwords are
not encrypted, merely obscured.
x11vnc has the even less secure -passwd and -viewpasswd supplied on
the command line. Be careful with these since they could be read by
users with something like the ps(1) command. On some operating systems
x11vnc tries to quickly overwrite them on the command line but it doesn't
work everywhere.
Regarding ViewOnly passwords (where a VNC client using that password
can only watch the screen, not interact with it), this is not available
with -rfbauth, but only with -passwdfile, -passwd, and -viewpasswd.
"
set helptext(SSL:) "
In this sub-menu we provide the options related to SSL encrpytion
and authentication.
There is a built-in mode (-ssl) using the OpenSSL library, and a 2nd
using the external stunnel program (-stunnel, that needs to be installed
on the system). Either may require or benefit from having PEM certificate
files specified.
"
set helptext(Misc-Perms:) "
In this sub-menu we provide some lesser used permission options.
Regarding -alwaysshared, -nevershared, and -dontdisconnect, you probably
should never use them and just use x11vnc's -shared and -forever options
instead (these give basically the same functionality and if you mixed
them too much unexpected things may happen).
"
#'
set helptext(AlphaBlending:) "
In this sub-menu we provide some tweak parameters for cursors (little
icon at the mouse pointer) that have transparency (i.e. an Alpha channel
in addition to Red, Green, and Blue RGB channels). For these cursors,
some of the graphics underneath the cursor is allowed to be blended in:
e.g. a drop-shadow (a terrible effect IMNSHO).
AlphaBlending for x11vnc is only available when the XFIXES X extension is
present (since otherwise it cannot see the cursors at all and so applies
heuristics to show some fake cursors). AlphaBlending is only a problem
with x11vnc when the cursors are not opaque.
Opaque cursors (e.g. bitmap or simply colored cursor) are rendered
correctly by x11vnc. Only when there is transparency does x11vnc have
to make some approximation to transform the cursor to be opaque (the
VNC protocol does not provide for an alpha channel in cursors, only RGB).
The items in this sub-menu let you tweak x11vnc's approximation scheme
for cursors with transparency. Hopefully you won't have to use them.
Certain cursor \"themes\" may require adjustment however.
"
#'
set helptext(OverlayVisuals:) "
In this sub-menu are some options that involve fixing color problems
for \"Overlay\" or \"Multi-Depth\" visuals. This problem is rare
since overlay and multi-depth visual video hardware is rare.
Some Sun, SGI, and HP machines are known to have them.
The short answer is if you have a multi-depth visual display (e.g. 8 and
24 bits), and you see messed up colors in x11vnc try the \"-overlay\"
option on Solaris or IRIX.
A brief Background on pixels, color, and visuals:
Pixels (picture elements) are kept in video memory as a certain number
of bits-per-pixel (bpp). Most common are 8bpp, 16bpp, and 32bpp.
Less common are 24bpp, 4bpp, and 1bpp (monochrome).
How pixel values (i.e. values of the bits) are rendered into colors on
the screen can be done via different \"Recipes\". These different
recipes are referred to as \"visuals\". E.g. for 8bpp there is
a PseudoColor visual that maintains a mapping (that can be changed
dynamically) of the pixel values (256 possible ones) into RGB values.
Other 8bpp visuals, e.g. StaticGrey and TrueColor have fixed, regular
mappings and so provide less variation in kinds of colors.
A visual's \"depth\" is how many of the pixels are used in the
actual recipe. This may sound wasteful (i.e. not using some of the
bits), but for 32bpp (4 billion colors) that is too much and nearly
always only 24 for them are used. The most common Visual seems to
be depth 24 TrueColor at 32bpp. This provides 16 million colors
which is more than the number of pixels on most screens (1280x1024 =
1.3 million pixels). Another sometimes used visual that ignores some
bits is depth 15 TrueColor at 16bpp.
OK, now, finally, to the Overlay Visuals. Some hardware (or software
emulations) allow different depth visuals to be used on the display
at the same time. The pixels of windows using different depth visuals
may overlap.
The most common seems to be both 8 and 24 depth visuals on a 32bpp setup.
24 of the pixels can be used for one visual and the remaining 8 for the
other. This is sometimes referred to as \"8+24\" mode. Furthermore,
a speedup is achieved because writing graphics data to, say, the 8bit
visual does not destroy the image data in the 24bit visual. Evidently
popup menus can be done very quickly this way: they use the 8bit visual
and when the popup goes away the graphics data in the 24bit visual is
immediately reexposed without having the application redraw it.
Also, some legacy applications can only use 8bpp visuals. But in these
days of high color graphics and web browsers one would like the rest
of the desktop to use depth 24 visuals. They often work on the multi
depth visuals.
How does this effect x11vnc? x11vnc nearly always polls the root window
(container of all other windows). The root window will be one depth,
e.g. 8 or 24. Any windows using the *other* depth will appear to have
messed up colors (or just be black or some other solid color) when viewed
via x11vnc.
How to fix? Solaris and IRIX provide an API to extract the full snapshot
of the display with all the colors correct. It comes to x11vnc as depth
24 TrueColor. To enable this use the \"-overlay\" option. Performance
may be slower, but if the colors are correct that is a big improvement.
"
set helptext(8-Bit-Color:) "
Some older displays (e.g. with limited Video RAM) use 8 bits-per-pixel
color. This allows for only 256 different colors on the screen at the
same time. This sometimes leads to problems with viewing these 8bpp
displays via x11vnc. This sub-menu has some options that correspond to
workarounds for this case. If you can configure the machine to use 16bpp
it may be worth it to avoid the color problems (e.g. color flashing
as the 8bit colormap is switched).
"
set helptext(SubWindow:) "
This sub-menu has a couple options regarding having x11vnc poll a
single window, not the entire display. This way just the window
is shared.
Note if the application pops up multiple windows they are not tracked
and shared. So this is not application sharing. The application has to
be very simple (e.g. a simple terminal or the image window on a webcam)
for this mode to be usable.
"
set helptext(ResizeRotate:) "
This sub-menu has some options regarding screens that support the X
Resize, Reflection, and Rotation Extension (RANDR), and one expects screen
resizing, reflection, or rotation to take place during the x11vnc session.
This is pretty rare, but x11vnc seems to handle it reasonably well using
this X extension.
This mode is on by default in -id mode to try to track the changing
size of the SubWindow. It is not on by default for full-screen mode
because of the extra overhead, etc.
"
set helptext(WireFrame:) "
This sub-menu has some options for the x11vnc wireframing speedup scheme.
For x11vnc, Wireframing means to watch for toplevel windows being Opaquely
Moved or Resized. When x11vnc detects this, it stops polling the screen
and simply shows a \"wireframe\" outline of the window as it is being
moved or resized. This avoids \"screen polling thrashing\" when the
screen is changing so rapidly during this period. For various reasons
this is usually much faster then letting the window manager do its
own wireframing (you are encouraged to do Opaque moves and resizes
when using x11vnc!)
Also, once a moved window is released in its new position, x11vnc uses
the VNC CopyRect encoding to very efficiently update the VNC viewers
(each just copies the image data locally).
This sort of scheme was used much in the 1990's on local displays because
video hardware was slow at the time. x11vnc tries to use this same trick
as a speedup for its activities (the network is much slower than video
hardware writes, and the video hardware reads that x11vnc uses to poll
the screen are still slow today).
"
#'"
set helptext(Safe:) "
In this sub-menu are some options for making x11vnc operations
more, or less, safe. E.g. disable the running of external commands, etc.
You can also turn off the Remote control channel (NOTE that doing that
will disable the GUI from being able to communicate with x11vnc).
"
set helptext(X-ext:) "
In this sub-menu are a few rarely used options regarding some X extensions
used by x11vnc.
"
set helptext(Clipping:) "
In this sub-menu are some options regarding clipping or blacking out
portions of the Screen. E.g. under XINERAMA when the multiple monitors
are not the same size.
"
set helptext(Misc-Screen:) "
In this sub-menu are some little used options modifying aspects of
the screen source.
"
set helptext(Settings:) "
In this sub-menu are some options for saving and loading option settings.
The default file to store settings in is ~/.x11vncrc, but you can save
different \"profiles\" in other files for later use.
"
set helptext(Java-applet:) "
In this sub-menu are some options for running the built-in HTTP server
that delivers the TightVNC Java VNC Viewer applet (VncViewer.jar) to
clients. The viewer runs in their Web browser.
The default port listened on is 5800, so the URL is typically:
http://hostname:5800/
but this can be altered by -httpport, etc.
"
set helptext(ScrollCopyRect:) "
This sub-menu has some options for the x11vnc Scroll detection and
CopyRect speedup scheme.
For this mode, x11vnc \"spies\" on communication between the X server and
applications using the RECORD extension. It looks for various patterns
to detect a scrolled window. This only works for some applications,
fortunately some important ones.
Once the scroll is detected it uses the VNC CopyRect encoding for a
big speedup. Screen polling is also sped up for this scheme.
There are many tweakable parameters for this mode and they are described
in the sub-menu items.
"
set helptext(XDAMAGE:) "
The DAMAGE X extension allows the X server to send signals to x11vnc
telling it which regions of the screen have been changed. This improves
x11vnc's performance markedly. The DAMAGE extension must be available
on the display for this to work.
Unfortunately DAMAGE cannot be trusted completely for the changed regions,
because often the reported changed region is much larger than the actual
changed regions. Nevertheless, x11vnc uses the DAMAGE information very
effectively as hints to improve its performance.
The items in the sub-menu allow tweaking x11vnc's DAMAGE algorithm.
"
set helptext(SharedMemory:) "
This sub-menu provides some options regarding SYSV shared memory usage
(shm) by x11vnc. Usually you want shm turned on because the x11vnc
process is nearly always running on the same machine the X server process
is running on. SharedMemory gives a performance speedup. However, if you
need to modify this scenario for special usage these options allow you to.
"
set helptext(Misc-Debug:) "
This sub-menu contains a lot of debugging parameters usually used
for debugging x11vnc itself. This is unlike the -debug_pointer and
-debug_keyboard options that are useful in learning information, quirks,
etc. about your local display and environment.
"
set helptext(Selection:) "
This sub-menu contains some options centering around the Selection
(also referred to as the Clipboard, Cutbuffers, etc). x11vnc will try
to exchange the selections between the VNC viewers and the X server.
You can adjust that behavior with these options.
"
set helptext(WindowView) "
Set the Window View Mode for the gui. There are three modes:
- full: Presents the full gui (Actions, Clients, etc, buttons,
and the Text area and Set/Entry box).
- icon: Presents a small icon instead of the full gui. Moving
the mouse over it shows the VNC display name and any
connected clients. Clicking on the icon pops up a menu
of actions to perform. Among them is \"Properties\" that
allows setting more parameters. Clicking on \"Advanced\"
in \"Properties\" brings up the full gui.
- tray: Attempt to embed the small icon in the system tray. If
this fails it will resort to icon mode where the small icon
is a standalone window.
Note that in \"full\" mode if you delete the full gui window the gui
terminates (but the x11vnc server keeps running). However under \"icon\"
or \"tray\" mode if you bring up the full gui window via \"Properties ->
Advanced\" and then delete it the gui does NOT terminate.
Also note that by default in \"icon\" mode if you delete the icon
window both the gui *and* the x11vnc server terminate.
"
set helptext(gui) "
tkx11vnc is a simple frontend to x11vnc. Nothing fancy, it merely
provides an interface to each of the many x11vnc command line options and
remote control commands. See \"Help -> all\" for much info about x11vnc.
For a simplier gui, run x11vnc in \"tray\" or \"icon\" mode such as
\"-gui tray\", \"-gui icon\", or \"-gui tray=setpass\". In that
mode the full gui is only available under \"Advanced ...\".
Also, \"-gui ez\" will show fewer menu items (toggle via Misc -> simple_gui)
All menu items have a (?) button one can click on to get more information
about the option or command.
There are two states tkx11vnc can be in:
1) Available to control a running x11vnc process.
2) Getting ready to start a x11vnc process.
Most people will just use state 1).
In state 1) the Menu items available in the menus are those that
correspond to the x11vnc \"remote control\" commands. See the -remote
entry under \"Help -> all\" for a complete list. Also available is
the \"Actions -> stop\" item to shut down the running x11vnc server,
thereby changing to state 2). There are other actions available too.
In state 2) the Menu items available in the menus (\"Actions\", \"Clients\",
etc.) are those that correspond to command line options used in starting
an x11vnc process, and the \"Actions -> start\" item executes
x11vnc thereby changing to state 1). To see what x11vnc startup command
you have built so far, look at the (?) help for \"Actions -> start\"
and it will show you what the command looks like.
There is much overlap between the menu items available in state 1)
and state 2), but it is worth keeping in mind it is not 100%.
For example, you cannot set passwords or password files in state 1).
(update: simple password setting is now allowed in \"tray\" or \"icon\" mode).
Also note that there may be *two* separate X displays involved, not just
one: 1) the X display x11vnc will be polling (and making available to
VNC viewers), and 2) the X display this GUI is intended to display on.
For example, one might use ssh to access the remote machine where the
GUI would display on :11 and x11vnc would poll display :0. By default
the gui will display on the value in the DISPLAY env. variable followed
by the value from the -display option. To override this, use something
like: \"-gui otherhost:0\", etc.
GUI components:
--- ----------
1) At the top of the gui is a info text label where information will
be posted, e.g. when traversing menu items text indicating how to get
help on the item and its current value will be displayed.
2) Below the info label is the area where the menu buttons, \"Actions\",
\"Clients\", etc., are presented. If a menu item has a checkbox,
it corresponds to a boolean on/off variable. Otherwise it is
either a string variable, or an action not associated with a
variable (for the most part).
3) Below the menu button area is a label indicating the current x11vnc
X display being polled and the corresponding VNC display name. Both
will be \"(*none*)\" when there is no connection established.
4) Below the x11 and vnc displays label is a text area there scrolling
information about actions being taken and commands being run is displayed.
To scroll click in the area and use PageUp/PageDown or the arrow keys.
5) At the bottom is an entry area. When one selects a menu item that
requires supplying a string value, the label will be set to the
parameter name and one types in the new value. Then one presses the
\"OK\" button or presses \"Enter\" to set the value. Or you can press
\"Cancel\" or \"Escape\" to avoid changing the variable.
Many variables are boolean toggles (for example, \"Permissions ->
viewonly\") or Radio button selections. Selecting these menu items
will NOT activate the entry area but rather toggle the variable
immediately.
CASCADES BUG: There is a bug not yet worked around for the cascade menus
where the (?) help button gets in the way. To get the mouse over to
the cascade menu click and release mouse to activate the cascade, then
you can click on its items. Dragging with a mouse button held down will
not work (sorry!).
Key Bindings:
In the Text Area: Control-/ selects all of the text.
Anywhere: Control-d invokes \"Actions -> detach\"
Anywhere: Control-a invokes \"Actions -> attach\"
Anywhere: Control-p invokes \"Actions -> ping\"
Anywhere: Control-u and Control-r invoke \"Actions -> update-all\"
"
set under_wally "
Misc:
Since x11vnc has so many settings and to avoid further confusion,
the libvncserver options:
-alwaysshared
-nevershared
-dontdisconnect
are not available for changing in a running x11vnc (even though it
is feasible). These options overlap with the x11vnc options -shared
and -forever which are hopefully enough for most usage. They may be
specified for x11vnc startup if desired.

tkx11vnc is a simple frontend to x11vnc. It is currently running in
\"ez\" or \"simple\" mode. For many more options run it in normal
