Re: Console Button

[Carlos Pereira <carlos pehoe civil ist utl pt>]

Thanks a lot for the code and usefull discussion on the "Console Button" topic.
In case it is usefull for someone else, here is a working example, with two buttons:
1) a console button that shows up and down the console every time is pressed
2) a shell button that fires up a new xterm every time is pressed
I made the top level window really big, of the size of a typical application, so
the console and shell windows don't cover the "application" (i.e. the two buttons).
