learning "practical programming in tcl/tk" - can't use examples

[pauliwan]

hi

i want to learn tcl/tk. so i have bought the book practical programming in tcl/tk. but i can't use the example scripts. every time i got a error.

for example:
i have tried to built the " example browser"

http://www.beedub.com/book/2nd/TKEXAMPL.doc.html

but if i want to start the browser, i got this message:
error in startup script: invalid command name "Scrolled_Text"
while executing
"Scrolled_Text .body \
-width 80 -height 10\
-setgrid true"
invoked from within
"set browse(text) [Scrolled_Text .body \
-width 80 -height 10\
-setgrid true]"

i have changed usr/local/bin/wish to usr/bin/wish
but nothing happend

i am confused. what's wrong with the script?

i'm working with debian.

First, make sure you actually have "wish" installed in /usr/bin.

Then, check your version.

Then, and this is key, make sure there actually is a "Scrolled_Text" widget. I know of no such widget. There is an IWdiget named "scrolledtext" for which you would need to
load the iwidgets package, but that is syntactically different from "Scrolled_Text".

I'm not familiar with the example but might it require a previous example already extant?

After having made a search of "Scrolled_Text" in your link, i found :
"# Scrolled_Text is defined in Example 27-1 on page 346"

Check there ^^
