       loadTk - Load Tk into a safe interpreter.


       ::safe::loadTk slave ?-use windowId? ?-display displayName?

       Safe  Tk  is  based  on  Safe  Tcl,  which provides a mechanism that allows restricted and
       mediated access to auto-loading and packages for safe  interpreters.   Safe  Tk  adds  the
       ability  to  configure  the  interpreter  for  safe  Tk  operations  and load Tk into safe


       The ::safe::loadTk command initializes the required data  structures  in  the  named  safe
       interpreter  and  then  loads  Tk  into  it.   The interpreter must have been created with
       ::safe::interpCreate or  have  been  initialized  with  ::safe::interpInit.   The  command
       returns  the name of the safe interpreter.  If -use is specified, the window identified by
       the specified system dependent identifier windowId is used to contain the ``.''  window of
       the safe interpreter; it can be any valid id, eventually referencing a window belonging to
       another application. As a convenience, if the window you plan to use is a Tk Window of the
       application  you  can  use the window name (e.g. .x.y) instead of its window Id ([winfo id
       .x.y]).  When -use is not specified, a new toplevel window is created for the ``.'' window
       of  the  safe  interpreter.  On X11 if you want the embedded window to use another display
       than the default one, specify it with -display.  See the SECURITY ISSUES section below for
       implementation details.


       Please  read the safe manual page for Tcl to learn about the basic security considerations
       for Safe Tcl.

       ::safe::loadTk adds the value of tk_library taken  from  the  master  interpreter  to  the
       virtual  access  path  of  the safe interpreter so that auto-loading will work in the safe

       Tk initialization is now safe with respect to not trusting the slave's state for  startup.
       ::safe::loadTk  registers  the slave's name so when the Tk initialization (Tk_SafeInit) is
       called and in turn calls the master's ::safe::InitTk  it  will  return  the  desired  argv
       equivalent (-use windowId, correct -display, etc.)

       When  -use  is  not  used,  the new toplevel created is specially decorated so the user is
       always aware that the user interface presented comes from a potentially  unsafe  code  and
       can easily delete the corresponding interpreter.

       On X11, conflicting -use and -display are likely to generate a fatal X error.
