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 medi-
       ated 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  inter-
       preter.	 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 (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, spec-
       ify 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 vir-
       tual access path of the safe interpreter so that auto-loading will work in the safe inter-
       preter.

       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.
