There is not that many risks associated with the Tk toolkit. Essentially all
operations are available, except those :
- functions who return widgets that may not be
below the applet ``top widget''
.
This way, an applet cannot tamper with other widgets in the browser.
- bindings that may affect other widgets (class_bind, tag_bind)
- postscript saving of canvases
Note that Safetk (as camltk) does not export the low-level
Tcl/Tk evaluation function, so it is not possible to evaluate arbitrary
Tcl/Tk code.
