Sure It's possible, It's not TRUE multithreading AND it's a hack.
If you create a child object to do the copying, and do the other part with
behaviours&stuff, then you'll have some alternatives. I've done that once,
(copying files in background while showing animation on front). The main
problem comes when you have BIG files.
As no Xtra I know of (FileXtra (not very experienced), BuddyAPI nor
MasterApp) support what you could call, "command and wait for result"
operation.
For Example BuddyAPI, when given a command to copy a file has the syntax:
CopyOperationSuccess = baCopyFile(fromfile, tofile)
and returns 1/0 when either ready or has failed, and does not allow your
lingo to proceed. Compare this to Director's net operations, where you
1# Issue a task
2# repeatedly can check for the completion of the task
This automatically sets limits to the multithreading you can do.
Basically you should not call this multithreading, as the items handled are
far larger thean threads. IMHO the word "multitasking" would be more
descriptive. Director when programmed correctly has the ability to multitask
(like it was done in the old days, by slicing up the tasks into tiny bits
and completing a part of task a, then a part of task b etc.)
As Lingo is a slow language, meaning that the amount of time for actually
"tasking" will also be a lot, you should not do MT-engines, unless you
REALLY need em.
