Steve, To bind it back.. I'm not sure how to do it in IB to be honest. I don't think you can do it with only the published input in QC, because it's an input. You could publish the initial value in QC as an output, but I'm not sure how you bind something multiple times from inside IB. It'd be pretty easy to do it from cocoa.
What I meant though was that if you have a standard start value (i.e. it's the same every time the app loads), you can just set the slider to start at that value, and set the initial value of the text box to that value too. Just set the "title" value of the text field to whatever you want. Chris 2009/1/16 Steve Tinsky <[email protected]> > I was setting the start value in IB.
