# tkx11vnc v0.1
# 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.
"
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.
"
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 non-connected
state.
"
set helptext(attach) "
Attach to the x11vnc server, if possible. Switches to connected state
if successful. To change or set the X display use \"Displays -> display\"
"
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, 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 retrieved
from a running x11vnc server. Basically sets everything to 0 or
the string (unset).
"
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.
"
set helptext(Quit) "
Terminate the tkx11vnc gui. Any x11vnc servers 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 chose 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, or Button Clicks
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 \"Skip\".
"
set helptext(solid_color) "
Set the -solid color value.
"
set helptext(xrandr_mode) "
Set the -xrandr mode 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(all) $helpall
set helptext(Misc-Tuning:) "
These contain some miscellaneous tuning parameters that are not
often used. Placed here to avoid overcrowding in the Tuning menu.
"
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.
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.
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). One could also simply \"Actions -> detach\"
leaving the x11vnc server running. \"Actions -> attach\" would
reestablish the connection.
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).
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 text 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 text 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
\"Skip\" or \"Escape\" to avoid changing the variable. Some 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 directly.
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\"
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
