Command-entry widget?

[johannes nada kth se (Johannes Keukelaar)]

Hello all,

What widget would be most suitable to implement a command-entry widget, a sort 
of shell? What I am working on is an application that the user can interact 
with by typing perl to it directly. I am thinking along the lines of, say, an 
xterm-like environment, embedded in the rest of the application window. (It 
would be nice if cursor up/down would cycle through the history of commands at 
the current prompt, unlike the text widget. Also, some way of entering 
multi-line commands (by terminating the line with a \, for example) would be 
nice.) Anyone done this before? Hints? (I really don't feel like rehacking the 
text widget for this. *shiver*, nay, *SHIVER*)

Thanks!

Johannes.
