Jerry, Since I found the problem interesting and also potentially useful for something of my own down the track, I thought I’d have a quick go at making a control like this. It’s here: http://apptree.net/code/GCVolumeControl.zip It’s fairly basic, though it does what you want with the positioning and stopping on tick marks, etc. I subclassed NSControl rather than NSSlider but I kept some of the same method names so it’s easy to swap in. The knob itself is just a PDF resource which I created using my own Artboard app (graphic and original file included). Obviously you can change this to anything you like - my quick and dirty image is likely a bit short of your needs. Hopefully you find it useful, and at least having the source you can customise it easily compared to standard classes. No licensing issues from me either. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
