Detecting a user click while in a lengthy task (mainthread)

Hi list,

I need to offer the user to cancel a lengthy blocking task (suppose it can not be threaded, and thus runs in the mainthread). basically something like while(!cancelled) { // do something }.

The problem here is that the action of my cancel button is not called because the UI is hanged by the task. Is it possible in the while above, to add something like [[NSRunLoop currentRunLoop] runMode:XXXX beforeTime:[NSDate dateWithTimeIntervalSinceNow:0.1]] ??

So that the runloop will run a little at each cycle and the user click will be processed ? if yes what is the mode i need to pass (XXXX) ? NSDefaultRunLoopMode or NSEventTrackingRunLoopMode ?

thanks for any help.

PS : i know i should thread this, but it is much too complex for the moment... _______________________________________________ Do not post admin requests to the list. They will be ignored.
