But as I said in the post - the slider is hooked up via bindings in the UI to a
label which shows the value *as you slide it*, so it needs to be continuous for
that purpose. Then when you let go, only then do I want the final value to be
delivered to the app.
were it simply a matter of turning continuous off I wouldn’t have had a
problem.
Surprisingly enough the thing I assumed would be the hardest, turned out to be
the easiest, mouseDown is documented to start a local event loop capture and it
doesn’t return until it’s all over .. so it just took this.
import Cocoa
public protocol RKEndValueSliderTarget : NSObjectProtocol
{
func sliderValueChangeEnded( slider : NSSlider )
}
public class RKEndValueSlider: NSSlider
{
public var endValueReceiver : RKEndValueSliderTarget?
public override func mouseDown( theEvent : NSEvent )
{
super.mouseDown( theEvent )
endValueReceiver?.sliderValueChangeEnded( self )
}
}
