Most of the examples that I have been studying involves one NSTableView in a window.

My question is how to implement two NSTableViews in a single window?

It would appear to me that it would only require to implement one version of the datasource methods and the implementation would be in the code of the datasource methods such as

-(int)numberOfRowsInTableView: (NSTableView *)aTableView;

and in the code of the datasource method, it needs to determine which tableView is making the call and then return with the appropriate number of rows based on the object/array that is viewed in the NSTableView.

If this is the case, then how do you determine which NSTableView made the call for the datasource method?

Compare aTableView to your instance variables of the two tableviews. Say your instance variables are tableView1 & tableView2.

if (aTableView == tableView1) {
return someNumber;
} else if (aTableView == tableView2) {
return someOtherNumber;
}

In the datasource methods, the argument aTableView allows the method to determine which of the NSTableView made the call.

My question is how is this handled with delegate methods such as
- (void)tableViewSelectionDidChange:
(NSNotification *)n

where there is no tableView argument to check which of the NSTableView of the window made the call for the delegate?

Thanks.

RTFM NSNotification, paying particular attention to the userInfo and object methods.

like so maybe:

Code:


- (int)numberOfRowsInTableView: (NSTableView *)aTableView
{
    int rowCount;
    
    switch ([aTableView tag])
    {
        case 100:
            rowCount = [queryArray count];
        break;
        
        
        case 200:
            rowCount = [currentMediaArray count]; 
        break;  


    }
    
    return rowCount;
}



- (void)tableViewSelectionDidChange: (NSNotification *)aNotification
{

    switch ([[aNotification object] tag])
    {
        case 100:
        [self doThis]
        break;
        
        
        case 200: 
        [self doThat];
        break;  

    }

}
