NAME

       safe::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 (e.g., from 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.
