Michael Hanni <mhanni@sprintmail.com> suggests:
|
||||
|
||||
I understand that nsTimer.cpp in base/rhapsody/ needs to be completed,
|
||||
yes? Wouldn't this code just use some NSTimers in the NSRunLoop?
|
||||
|
||||
Timer = [NSTimer timerWithTimeInterval:0.02 //seconds
|
||||
target:self
|
||||
selector:@selector(doThis:)
|
||||
userInfo:nil
|
||||
repeats:YES];
|
||||
[[NSRunLoop currentRunLoop] addTimer:Timer
|
||||
forMode:NSDefaultRunLoopMode];
|
||||
|
||||
I only looked at nsTimer.cpp briefly, but could something like this work
|
||||
if imbedded in all that c++? ;-)
