This is a sample of the safe-Tk slave interpreter. \
|
|
On the slave interpreter, 'tkoptdb.rb' demo is running.
|
|
( NOTE:: a safe-Tk interpreter can't read options \
|
|
from a file. Options are given by the master interpreter \
|
|
in this script. )
|
|
The window shown this message is a root widget of \
|
|
the default master interpreter. The other window \
|
|
is a toplevel widget of the master interpreter, and it \
|
|
has a container frame of the safe-Tk slave interpreter.
|
|
'exit' on the slave interpreter exits the slave only. \
|
|
You can also delete the slave by the button on the toplevel widget.
