TCL_SetVar — Set a tcl/tk variable value
TCL_SetVar(varname, value [,interp])
character string. Contains the name of the tcl/tk variable to set.
may be a character string, a scalar, a real or string matrix (m x n). Contains the value to give to the tcl/tk variable.
optional character string parameter. Name of the slave tcl interpreter in which the operation has to be performed. If not provided, it defaults to the main tcl interpreter created by Scilab.
This routine allows to set a variable within a tcl/tk interpreter. When
tcl/tk support is enabled in scilab, this routine can be used to set up
the value of a tcl/tk variable. This can be useful to change some value in
the tcl/tk interpreter without having to build a tcl/tk instruction (and
use TCL_EvalStr).
TCL_EvalStr("toplevel .tst1");
// creates a toplevel TK window.
TCL_EvalStr("entry .tst1.e -textvariable tvar");
// create an editable entry
TCL_EvalStr("set tvar foobar");
// set the entry value
TCL_EvalStr("pack .tst1.e");
// pack the entry widget. It appears on the screen.
text=TCL_GetVar("tvar")
// retrieve the variable value
// change the entry text and repeat the last command ...
//delete the toplevel TK window.
TCL_EvalStr("destroy .tst1")
