TK_EvalStr Scilab Function

TK_EvalStr - Evaluate a string whithin the tcl/tk interpreter

Calling Sequence

TK_EvalStr(str)

Parameters

str : string or vector of strings, contains the tcl/tk instructions

Description

This routine allows to evaluate tcl/tk instructions with the tcl/tk interpreter launched with scilab.

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 TK_EvalStr() can be used to evaluate expression without having to write a tcl/tk in a separated file (this is done using TK_EvalFile).

Examples


//with one call
TK_EvalStr(['toplevel .foo1'
   'label .foo1.l -text ""TK married Scilab !!!""'
   'pack .foo1.l'
   'button .foo1.b -text close -command {destroy .foo1}'
   'pack .foo1.b'])

//step by step (debugging)
TK_EvalStr('toplevel .foo2');
// creates a toplevel TK window. 
TK_EvalStr('label .foo2.l -text ""TK married Scilab !!!""');
// create a static label
TK_EvalStr('pack .foo2.l');
// pack the label widget. It appears on the screen.
text='button .foo2.b -text close -command {destroy .foo2}';
TK_EvalStr(text);
TK_EvalStr('pack .foo2.b');

//kill the windows by program
TK_EvalStr('destroy .foo1');
TK_EvalStr('destroy .foo2');
