"\n"

|
|
" (However see the -control option below that can replace -connect.)\n"
|
|
"\n"
|
|
" The VNC viewer at viewer_host MUST be in 'listen' mode. This is because\n"
|
|
" a new VNC connection (and viewer window) is established for each new\n"

|
" toplevel window that the application creates. For example:\n"
|
|
"\n"

|
"\n"

" The '-connect viewer_host:0' indicates the listening viewer to connect to.\n"

" ssh -R 5500:localhost:5500 user@server_host\n"
|
|
"\n"
|
|
" (then use -connect localhost:0)\n"
|
|
"\n"
|
|
" The -id/-sid option is as in x11vnc(1). It is either a numerical window\n"

" id or the string 'pick' which will ask the user to click on an app window.\n"

"\n"

"\n"

" The main idea is to provide simple application sharing for two or more\n"

" parties to collaborate without needing to share the entire desktop. It\n"
|
|
" provides an improvement over -id/-sid that only shows a single window.\n"
|
|
"\n"
|
|
" Only reverse connections can be done. (Note: one can specify multiple\n"
|
|
" viewing hosts via: -connect host1,host2,host3 or add/remove them\n"
|
|
" dynamically as described above.)\n"
|
|
"\n"
|
|
" If a new window obscures an old one, you will see some or all of the\n"
|
|
" new window in the old one. The hope is this is a popup dialog or menu\n"
|
|
" that will go away soon. Otherwise a user at the physical display will\n"
|
|
" need to move it. (See also the SSVNC viewer features described below.) \n"
|
|
"\n"
|
|
" The viewer side cannot resize or make windows move on the physical\n"
|
|
" display. Again, a user at the physical display may need to help, or\n"
|
|
" use the SSVNC viewer (see Tip below.)\n"
|
|
"\n"
|
|
" Tip: If the application has its own 'resize corner', then dragging\n"
|
|
" it may successfully resize the application window.\n"
|
|
" Tip: Some desktop environments enable moving a window via, say,\n"
|
|
" Alt+Left-Button-Drag. One may be able to move a window this way.\n"
|
|
" Also, e.g., Alt+Right-Button-Drag may resize a window.\n"
|
|
" Tip: Clicking on part of an obscured window may raise it to the top.\n"
|
|
" Also, e.g., Alt+Middle-Button may toggle Raise/Lower.\n"
|
|
"\n"
|
|
" Tip: The SSVNC 1.0.25 unix and macosx vncviewer has 'EscapeKeys' hot\n"
|
|
" keys that will move, resize, raise, and lower the window via the\n"
|
|
" x11vnc -remote_prefix X11VNC_APPSHARE_CMD: feature. So in the\n"
|
|
" viewer while holding down Shift_L+Super_L+Alt_L the arrow keys\n"
|
|
" move the window, PageUp/PageDn/Home/End resize it, and - and +\n"
|
|
" raise and lower it. Key 'M' or Button1 moves the remote window\n"
|
|
" to the +X+Y of the viewer window. Key 'D' or Button3 deletes\n"
|
|
" the remote window.\n"
|
|
"\n"
|
|
" You can run the SSVNC vncviewer with options '-escape default',\n"
|
|
" '-multilisten' and '-env VNCVIEWER_MIN_TITLE=1'; or just run\n"
|
|
" with option '-appshare' to enable these and automatic placement.\n"
|
|
"\n"
|
|
" If any part of a window goes off of the display screen, then x11vnc\n"
|
|
" may be unable to poll it (without crashing), and so the window will\n"
|
|
" stop updating until the window is completely on-screen again.\n"
|
|
"\n"
|
|
" The (stock) vnc viewer does not know where to best position each new\n"
|
|
" viewer window; it likely centers each one (including when resized.)\n"
|
|
" Note: The SSVNC viewer in '-appshare' mode places them correctly.\n"
|
|
"\n"
|
|
" Deleting a viewer window does not delete the real window.\n"
|
|
" Note: The SSVNC viewer Shift+EscapeKeys+Button3 deletes it.\n"
|
|
"\n"
|
|
" Sometimes new window detection fails.\n"
|
|
"\n"
|
|
" Sometimes menu/popup detection fails.\n"
|
|
"\n"
|
|
" Sometimes the contents of a menu/popup window have blacked-out regions.\n"
|
|
" Try -sid or -showmenus as a workaround.\n"
|
|
"\n"
|
|
" If the application starts up a new application (a different process)\n"
