caret location

[Kirt Fitzpatrick]

Does anyone know how to obtain the caret location either in the line or in the file?  selectedRanges is not implemented by OakTextView.

Thanks,

kirt

The class does not expose this via any attributes.

It does however have lineNumber and columnNumber as bindable  
properties. So in practice you can use that to get the line/column  
position.

I did not find those properties as exposedBindings for OakTextView.  My test code follows:

    bindings = [responder exposedBindings];
    int i;

    for ( i=0; i < [bindings count]; i++ ) {
        NSLog( @"binding: %@", [bindings objectAtIndex:i] );
    }


This produced the following output.
    2007-05-08 09:43:51.800 TextMate[915] binding: hidden
    2007-05-08 09:43:51.800 TextMate[915] binding: toolTip



Also attempting to bind to lineNumber or columnNumber
    [self bind:@"lineNumber" toObject:responder withKeyPath:@"lineNumber" options:nil];


causes the following error
     [<OakTextView 0x630c50> valueForUndefinedKey:]: this class is not key value coding-compliant for the key lineNumber



However lineNumber and columnNumber appear to be available in OakStatusBar.  But I do not know how to grab that object.  Any ideas?

thanks again,
kirt

You need to send the bind:… message to the text view. E.g.:

     NSMutableDictionary* dict = [NSMutableDictionary dictionary];
     [textView bind:@"lineNumber"   toObject:dict  
withKeyPath:@"line"   options:nil];
     [textView bind:@"columnNumber" toObject:dict  
withKeyPath:@"column" options:nil];

     NSLog(@"%@", dict);

     // cleanup
     [textView unbind:@"lineNumber"];
     [textView unbind:@"columnNumber"];
