.SH Description
When tcl/tk support is enabled in scilab, you can evaluate tcl/tk expression
from scilab interpreter. In fact, scilab launches a slave tcl/tk interpreter.
The scilab instruction \fBTK_EvalStr()\fP can be used to evaluate expression
without having to write a tcl/tk in a separated file (this is done using
TK_EvalFile).
.SH EXAMPLE
.nf
TK_EvalStr('toplevel .foo');
// creates a toplevel TK window.
TK_EvalStr('label .foo.l -text ""TK married Scilab !!!""');
// create a static label
TK_EvalStr('pack .foo.l');
// pack the label widget. It appears on the screen.
text='button .foo.b -text close -command {destroy .foo}';
TK_EvalStr(text);
TK_EvalStr('pack .foo.b');
