Safe Tk(n)                                  Tk Built-In Commands                                  Safe Tk(n)

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 inter-preter interpreter
       preter 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 Win-dow Window
       dow  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 cor-responding corresponding
       responding interpreter.

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