# YRKSpinningProgressIndicator and SPIDemo.app



by Kelan Champagne (http://yeahrightkeller.com)



Please feel free to send me questions or comments.



## Overview



YRKSpinningProgressIndicator is a clone of the "Spinning style"

NSProgressIndicator that can be set to an arbitrary size and color. The

background color can also be set, or it can be transparent. You can even

change the color in real-time while it's animating. SPIDemo is an app to demo

its use.



## Version History



* v1.0  2008-07-08  Initial Release.

* v1.1  2009-02-14  Fixes from Eric Roccasecca.

* v1.2  2009-12-21  Added determinate mode and threaded animation, mostly via

email from Rowan Beentje (from SequelPro).

* v1.3  2010-09-06  Pulled fixes, name improvements from mikeabdulla and

  uncomplex.

  NOTE: This version is not backwards-compatible with

  previous versions due to the name changes.



## Features



* Can be set to arbitrary size and color.

    * Can even be changed while animating.

* Background color can be set arbitrarily or be transparent.

* Has determinate mode that is a pie-chart of the progress.

* Mostly compatible with OS X 10.4 (Tiger).  I think there might be some issues

  with the run modes with the NSTimer-based animation, but I don't have access

  to a Tiger machine right now, so I can't check.



## Code Architecture



* Implemented as a subclass of NSView.

* Animation is done with an NSTimer, or on a separate thread (when

  setUsesThreadedAnimation:YES).  You can even swap between the two while the

  animation is running.



## Code Conventions



* Instance variables are prefixed with an underscore (i.e. "_").
