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 mechanismthat allows restricted and mediated access to auto-loading
and packages for safe interpreters. Safe Tk adds the abil-
ity 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 interpreter must have been created with ::safe::interpCreate or have been initialized with ::safe::interpInit. The command returns the name of thesafe interpreter. If -use is specified, the window identi-
fied by the specified system dependent identifier windowIdis used to contain the ``.'' window of the safe inter-
preter; 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 applica-
tion you can use the window name (e.g. .x.y) instead of itswindow 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 imple-
mentation 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 safeinterpreter so that auto-loading will work in the safe
interpreter. Tk initialization is now safe with respect to not trustingthe 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 willreturn 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 inter-
face 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.SEE ALSO
