    <p>I've seen some threads with a similar question to this (not exactly the same) but the solutions there didn't solve my problem. I've create a NSTableView with a couple clickable elements in each TableCellView -- a TextField, a DatePicker and a Button -- and I need to be able to click into each of these without first selecting the row they are in. I achieved this by using <code>setSelectionHighlightStyle: NSTableViewSelectionHighlightStyleNone</code> However, I still need to know the index of the row that is being edited, because I need to pass the edits into a model object associated with each row. I tried writing the following, which was the suggestion of some of the other threads I mentioned, but it didn't do anything.</p> <pre><code>- (BOOL)tableView:(NSTableView *)tableView shouldTrackCell:(NSCell *)cell forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{ return YES; } </code></pre> <p>I'm not 100% sure if that's the wrong method to use for this, or if I'm just implementing it incorrectly. Any tips on how I could go about this would be awesome.</p> <hr> <p><strong>Edit:</strong></p> <p>Here's my attempt at implementing Steve Waddicor's suggestions:</p> <p>Making the ViewController the NSTableViewDataSource and set the TableCellView as the delegates for the objects (code is in MyViewController.m):</p> <pre><code>- (void)awakeFromNib{ [self.tableView setDataSource:self]; } - (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row { CustomTableCellView *view = [self.tableView makeViewWithIdentifier:@"MyIdentifier" owner:self]; [view.textField setDelegate:view]; [view.datePicker setDelegate:view]; return view; } //----------------------- //----------------------- //----------------------- NSTableViewDataSource Protocol Requirements: - (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView { return [self.tableView numberOfRows]; } - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { return [self.tableView rowViewAtRow:rowIndex makeIfNecessary:NO]; } </code></pre> <p>and in CustomTableCellView, this is the delegate method which isn't being called when I click on the TextField, which leads me to believe that the delegates aren't being set for the objects correctly:</p> <pre><code>- (void)mouseDown:(NSEvent*) theEvent{ NSLog(@"TEST"); } </code></pre>

    1. COYou are indeed using a view-based table view, not a cell-based table view, correct?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
