NSTableView cell (CPTextField) values come up empty when accessing them directly.

[Samir Gartner]

Hello guys and gals, I'm implementing a custom view that has a NSTableView bound to an NSArrayController (working with CUP), I did it all programmatically (I don't like to use Xib's that much). I wan't to add an NSByteCountFormatter to the size cell (like in the CUP video). I tried to do it inside the viewForTableColumn delegate method  but unfortunately I cannot access the CPTextField stringValue directly. If I print the dataView it comes up as a CPTextField, and I can see the values there inside the variable _stringValue and _value, but if I try to read them or use them directly they come up empty, although the values do appear inside the table columns.

- (CPView) tableView:(CPTableView) aTableView viewForTableColumn:(CPTableColumn)aTableColumn row:(CPInteger)aRowIndex
{
 var dataView = [aTableColumn dataViewForRow:aRowIndex];
 var aStringValue = [dataView stringValue];
 console.log(dataView);
        console.log(aStringValue);

 return dataView;
}

Can someone please point me to the right direction, either by adding the NSByteCountFormatter in a different way or accessing the values inside the delegate method?

i guess that at this time the cell values are not set yet.

try [dataView setFormatter:yourFormatter]

Also, the above is not correct. You would instead:

- (CPView) tableView:(CPTableView) aTableView viewForTableColumn:(CPTableColumn)aTableColumn row:(CPInteger)aRowIndex
{

// use this method //
var dataView = [aTableView makeViewWithIdentifier:@“whatever" owner:self];
// /////////////////

var aStringValue = [dataView stringValue];
console.log(dataView);
console.log(aStringValue);

return dataView;
}

You were right, thank you!. I thought I had to use

 [CPByteCountFormatter stringFromByteCount:byteCount]

 and set the field value manually.
