Scilab Function

TK_SetVar - Set a tcl/tk variable value

### Calling Sequence

  `TK_SetVar(varname, value)`

### Parameters

- `varname` : string character Contains the name of the tcl/tk variable to set.
- `value` : string character Contains the value to set up in the tcl/tk variable

### Description

This routine allows to set a variable within the 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 without having to build a tcl/tk instruction (and use TK_EvalStr).

### Examples

    TK_EvalStr('toplevel .tst2');
    // creates a toplevel TK window.
    TK_EvalStr('label .tst2.l -textvariable tvar');
    // create a static label
    TK_EvalStr('pack .tst2.l');
    // pack the label widget. It appears on the screen.
    TK_SetVar('tvar','This text has been set directly within scilab');
