[vtkusers] Question about tcl/tk-VTK application,..

[Miguel Ángel Rodríguez Florido]

	Hi all,

	Sorry, because this question is more related to tcl/tk, but I know that 
many people that works under VTK uses Tcl/Tk..so sorry again for people 
that not.

	My question is very simple, but I haven't found how to do that.

	I have a Tcl/Tk procedure like:

	proc myproc {vars} {
	
	code
	
	  foreach a $list {
		button .blabla.$a -text $a -command {puts $a}
	  }

	}


However the foreach variable $a doesn't exist in the -command option. I 
mean, I got an error when it runs this puts: puts $a.
	If I do global this variable: global a, I only got the last value of $a.

	So I understand that the foreach command is running first, and when it 
finishs, the tcl run the -command option of the tk button.

	How can I access to the variable "a" in the -command button option??. I 
mean, how can I get the value of "a" at foreach step in the -command option?

	Thank you very much.
	Best regards.
