How to access a TK-variable from newlisp?

[HPW]

I want to access TK-variables

Code Select Expand

> (tk "set test 123")
"123"
> (tk "set test")

>

When I do the second I get a message window 'can't read "test": no such variable'. On a native TCL-console it works in that way. It respond with the content of the variable. Would be usefull to access all the global vars 'Ide(xxxxxxx)'



Any hints?

Thanks for posting all these improvements in the Tcl.Tk code. About setting variables in Tcl/Tk: I just try to avoid it and work with the return values from the 'tk' statement stored in LISP variables.



To declare Tcl variables from newLISP, I think you would have to create a child interpreter. But I never went much into Tcl/Tk and newlisp-tk.tcl is the only program in Tcl/Tk I have ever written.

I have only used the 'tk' call. And I want not declare them, I want read and write to existing vars. Ok my test was a new var, but it also works not with the existing one's from the config-file.

try this:



(tk "global Ide; set Ide(fontSize)")



or this:



(tk "global Ide; set Ide(fontSize) 16")



Then open a editor/browser window ;)

Lutz,



thanks for the hint.

I had thought that it could be a problem with the scope of the vars.

I had tried around, but with no satisfying solution.

So this is short and easy.

Fits very good in the concept of newlisp. :-)
