NAME

       loadTk - Load Tk into a safe interpreter.

SYNOPSIS

       ::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 interpreters.

DESCRIPTION

       The ::safe::loadTk command initializes the required data structures in the named safe interpreter and then loads Tk into it.   The  command
       returns	the  name  of the safe interpreter.  If -use is specified, the window identified by the specified system dependent identifier win-
       dowId 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 (eg:
       .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.
