macOS Using Object Controller for Binding

[Sergio10]

Hi,
I use Object Controller in xcode 3.1 for the control bindings.

I want that edit field control shows my slider position when drag it.

How do I know what exactly value I need to bind in Binding Inspector of the Interface Builder("stringValue", "value" or "floatValue") ?

Thanks,
Sergio

I'd bind both your text field and slider to either file's owner or an object controller to the same value. Bindings don't work from a UI object to another, they work from a UI object to a controller.

I mean how to know that max slider position parameter is "maxValue" not "MAX_VALUE" or something else? Where can I see controls name convention parameter when I bind it via Interface Builder?

While bindings can do this, you can't bind a control directly to another with this approach. I would suggest reading through the intro to bindings.

What you can do is control-click your slider and drag to the text field, and then select "takeIntegerValueFrom:" (or one of the other similar methods). You can then select on the slider attributes inspector "Continuous" for it to update instantly.
