.SH Description
This function must be called in a tcl/tk script executed from scilab.
It allows to associate scilab actions to tcl/tk widgets (graphic
objects). The string str is put in the scilab interpreter buffer
which then evaluates it. This has in general no border effect in the
tcl/tk interpreter.
.SH Example (tcl/tk script)
.nf
# this text must be saved into a file, for instance
# '/tmp/test.tcl'
# then launch scilab and type TK_EvalFile('/tmp/test.tcl');
