There are several ways of doing this, since you are designing the
application yourself.
A simple method is to use NSTimer, and then set flags in your code where
it goes busy.
1: Create a scope counter, set it to 0.
2: Set up the NSTimer
3: Start the automatic operations. Each operation should be shielded with
"BeginOperation" and "EndOperation".
BeginOperation does this:
Disable the NSTimer
Increment the scope counter
EndOperation does this:
Decrement the scope counter
If the scope counter goes zero, enable the NSTimer
For an example on how to use NSTimer, you can look in the /Developer/
Examples/AppKit/CircleView/ project.
Hope this gets you started. :)
Love,
Jens
