The other post "Word Processor in Flash" reminded me of a problem I
had a while back which I'm sure someone on this list would have an
idea how to get round.
I was trying to build a Flash application that behaved much like a
command line OS. So it consisted of an input text field, which
printed text and waited for commands to be written into it before
performing certain procedures.
The crux of the problem involved catching input commands, such as
delete, enter etc, before they were applied to the Text field itself
so they could be interpreted and more importantly controlled.
I tried running a watch on the textfield variable, which so nearly
let me do everything I wanted but wouldn't allow me to disallow the
functionality (delete would still delete even though you got a chance
to view the changes before they were applied).
Does anyone have examples of this kind of functionality already
built? I assume a constant updated variable of the content must be
created to allow switching back to previous states if the user does
something that's not allowed. A running example would be a great help.
Thanks,
Dan Efergan
