This fragile solution broke in 10.7.)
You could just round the values received to the nearest whole number. I guess what might be nice is a tendency for it to "snap" to the zero position when the slider is dragged close to it. You might be able to do that with a standard slider by manipulating the values close to the zero point, but to get this really working well you'd probably want a subclass of NSSliderCell - you'd probably also want to have some sort of override, such as when the option key is pressed, otherwise it will be impossible to set values very close to 0, such as 1. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
