I have a cocoa app in which I have set up an NSTimer. That timer is configured to send a message periodically.

There are some sliders on a window in this application. If I start moving a slider, the timer is frozen until I release the mouse button.

Any way to get the timer pulse delivered while I move the slider?

The slider is probably running its own event loop in mouseDown:, which bypasses normal event handling. Try creating the timer and then scheduling it manually in NSDefaultRunLoopMode and NSEventTrackingRunLoopMode, or kCFRunLoopCommonModes.

I considered moving the timer into another thread (NSThread), but I'm not sure if that is the ideal solution or not?


I'd try the runloop approach first.
