TCL_EvalStr
Evaluate a string whithin the Tcl/Tk interpreter
Calling Sequence
TCL_EvalStr(str [,interp]) res = TCL_EvalStr(str [,interp])
Arguments
- str
string or matrix of strings, contains a Tcl/Tk script in each element.
- interp
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.
- res
result of the evaluation, if it is successful. This is a character string matrix giving the evaluation result for each element of the input argument str
Description
This routine allows to evaluate Tcl/Tk instructions with the Tcl/Tk
interpreter launched with Scilab (when the interp parameter
is not given), or in a slave interpreter.
When Tcl/Tk support is enabled in Scilab, you can evaluate Tcl/Tk
expression from Scilab interpreter. In fact, Scilab launches a main Tcl/Tk
interpreter. The Scilab instruction TCL_EvalStr can be used
to evaluate expressions without having to write Tcl/Tk instructions in a
separated file (this capability is provided by
TCL_EvalFile).

Examples
//with one call TCL_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) TCL_EvalStr("toplevel .foo2"); // creates a toplevel TK window. TCL_EvalStr("label .foo2.l -text ""TK married Scilab !!!"""); // create a static label TCL_EvalStr("pack .foo2.l"); // pack the label widget. It appears on the screen. text="button .foo2.b -text close -command {destroy .foo2}"; TCL_EvalStr(text); TCL_EvalStr("pack .foo2.b"); //kill the windows by program TCL_EvalStr("destroy .foo1"); TCL_EvalStr("destroy .foo2"); //with one call, and in a slave interpreter TCL_CreateSlave('TCLSlave'); TCL_EvalStr('set test ""in Slave TCL Interp""','TCLSlave'); TCL_GetVar('test','TCLSlave') TCL_DeleteInterp('TCLSlave') // return a result res = TCL_EvalStr("expr 1+1") res = TCL_EvalStr("tk_messageBox -message Hello -type okcancel") res = TCL_EvalStr(["expr 4+5" "lsearch -all {a b c a b c} c" ; "list [list a b c] [list d e f] [list g h i]" "llength {a b c d e}"])
