Do I need to use Bindings?

Question

Hi All
I wonder if you can help
I have a class (driver.m) that takes an input from a USB device (the callback function is embedded into the class and passes data back to the instance of the class).
There are a number of instance variables that change depending on the incoming data.
say
int analog1;
How do I monitor the data coming into that class in a cocoa window.
For instance analog1 has constantly changing data as a int value 0-255 which I wish to view in a NSLevelindicator.
Should I be using bindings for this type of thing as most of the bindings demos seem to be on cocoa elements changing cocoa elements.
If you could point me in the right direction I would appreciate it
Cheers
Steve

Answer 1

So if you take the following:
@interface Driver : NSObject
    int driverValue;
@property (readwrite, assign) int driverValue;
@end
@implementation Driver
@synthesize driverValue;
@end
Then elseware
    Driver *instance1 = [[Driver alloc] init];
    Driver *instance2 = [[Driver alloc] init];
I should be able to set up a slider for the driverValue of instance1 and a separate slider for driverValue of instance2?
Beacuse in interface builder when I create an object (blue qube) I can set the class to Driver and I can set the bind to driverValue. But I can't see were I tell IB which instance this is belonging to. So even if I do a second object (blue qube) I can only duplicate what I have already done I can't see were I assign one (blue qube) to instance1 and the other to instance2.
