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. # D means it is a good idea to delay a little before querying # (i.e. perhaps it causes x11vnc to do a lot of work, new fb) # No longer used, -sync is used instead. # 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 # -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_template {} { global template set template " Row: Actions Clients Permissions Keyboard Pointer Help Row: Displays Screen Tuning Debugging Misc Actions =SA start =RA stop =GA attach =RA detach -- =RA ping =RA update-all =GA clear-all -- =RA stop+quit =GA Quit Help =GA gui =GA all Clients =RQA current: =F connect: =RQA disconnect: -- accept: gone: vncconnect -- http =F httpdir: httpport: enablehttpproxy Displays display: =F auth: desktop: rfbport: =0 gui: Screen =DRA refresh =DRA reset =DRA blacken -- =D id: =D sid: =D scale: -- =D overlay overlay_nocursor -- =D visual: flashcmap notruecolor -- =DP blackout: =D xinerama -- = xrandr =-C:resize,newfbsize,exit xrandr_mode: padgeom: Keyboard norepeat add_keysyms modtweak xkb skip_keycodes: -- =FP remap: -- clear_mods clear_keys Pointer =-C:none,arrow,X,some,most cursor: noxfixes -- cursorpos nocursorshape -- buttonmap: -- xwarppointer Misc =F rc: norc -- nofb -- nobell nosel noprimary -- bg =-C:ignore,exit sigpipe: =0 inetd -- =RA remote-cmd: =GA all-settings Debugging debug_pointer debug_keyboard =F logfile: =GA show-logfile =GA tail-logfile quiet -- =GA show-start-cmd =G debug_gui Permissions =RQA lock =RQA unlock =SQA deny_all -- =FP allow: localhost =RA allowonce: -- viewonly shared forever -- =RA noremote -- =SA alwaysshared =SA nevershared =SA dontdisconnect -- viewpasswd: =F passwdfile: =0 storepasswd =F rfbauth: passwd: -- safer unsafe Tuning =-C:1,2,3,4 pointer_mode: input_skip: nodragging alphacut: alphafrac: alpharemove -- =D noshm flipbyteorder onetile -- wait: defer: nap screen_blank: -- fs: gaps: grow: fuzz: -- threads rfbwait: -- progressive: " } 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.

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. Most menu items have a (?) button one can click on to get more information about the option or command. In most cases it will be text extracted from that in \"Help -> all\". 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. GUI components: --- ---------- 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. 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). 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. 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 use PageUp/PageDown or the arrow keys. 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: 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.
