NAME

       loadTk - Load Tk into a safe interpreter.

SYNOPSIS

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

DESCRIPTION

       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
       interpreters.

       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.

SECURITY ISSUES

       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
       interpreter.

       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.
