Hello,
I'm trying to get an NSTableView to be editable, and I am having
trouble getting a numerical value from the supplied object. The
setObjectValue method (?) supplies an argument called aData for the
specific row and column. That aData is an NSObject, and an NSString I
think. How do I convert that to a double floating point number? I
need to set a value in an array that is being passed from a Carbon app.
I've tried
double val = [aData doubleValue];
but that doesn't work. I have little experience with Cocoa and I
wrote this code years ago.
Thanks for any help,
Bob
- (void)tableView:(NSTableView *)aTableView setObjectValue:(id)aData
forTableColumn:(NSTableColumn *)aCol
row:(int)rowIndex
{
double val = [aData doubleValue];
