    <p>I'm trying to add <a href="http://juliuspaintings.co.uk/cgi-bin/paint_css/animatedPaint/070-NSTableView-ImageAndTextCell.pl" rel="nofollow noreferrer">this</a> example's ImageAndTextCell.h class to my project. I have added it successfully. It looks something like below</p> <p><img src="https://i.imgur.com/3pTMrP5.png" alt="this"></p> <p>On row click i get the selected index and on IBAction I need to change it to green color. Which works fine too. But when I click on another row, the previous rows green turns to red. Im sure the problem is with the logic of checking for the row. I have implemented the below code which failed</p> <pre><code> - (NSCell *)tableView:(NSTableView *)tv dataCellForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row { NSTextFieldCell *cell = [tableColumn dataCell]; if(tv== [self tableView]){ if([[tableColumn identifier] isEqualToString:COLUMN_TITLE]){ if(![tickTracker count]){ ImageAndTextCell *imageAndTextCell = (ImageAndTextCell *)cell; // Set the image here since the value returned from outlineView:objectValueForTableColumn:... didn't specify the image part... NSString *fileName = [[NSBundle mainBundle] pathForResource:@"Cross" ofType:@"png"]; NSImage *markerImage = [[NSImage alloc] initWithContentsOfFile:fileName]; [imageAndTextCell setImage:markerImage]; }else{ for (int i= 0;i &lt; [tickTracker count];i++){ NSLog(@" 123 number %@",[tickTracker objectAtIndex:i]); NSInteger myInteger = [[tickTracker objectAtIndex:i] integerValue]; [changedRows addObject:[tickTracker objectAtIndex:i]]; if(row == myInteger){ NSLog(@" %li value ",row); ImageAndTextCell *imageAndTextCell = (ImageAndTextCell *)cell; // Set the image here since the value returned from outlineView:objectValueForTableColumn:... didn't specify the image part... NSString *fileName = [[NSBundle mainBundle] pathForResource:@"Tick" ofType:@"png"]; NSImage *markerImage = [[NSImage alloc] initWithContentsOfFile:fileName]; [imageAndTextCell setImage:markerImage]; }else{ ImageAndTextCell *imageAndTextCell = (ImageAndTextCell *)cell; // Set the image here since the value returned from outlineView:objectValueForTableColumn:... didn't specify the image part... NSString *fileName = [[NSBundle mainBundle] pathForResource:@"Cross" ofType:@"png"]; NSImage *markerImage = [[NSImage alloc] initWithContentsOfFile:fileName]; [imageAndTextCell setImage:markerImage]; } } } return cell; } </code></pre> <p>Can someone help me on this? The object at index 0 in tickTracker is not set to green when it checks for object at index 1. </p> <p><strong>EDIT 1</strong>. Inside the ticktracker: </p> <p>-(IBAction)method:(id)sender{</p> <pre><code> NSUInteger idx = [[tableView selectedRowIndexes] firstIndex]; while (idx != NSNotFound) { int rowKey = (int)idx; NSNumber* rowNumber = [NSNumber numberWithInt:rowKey]; [tickTracker addObject:rowNumber]; idx =[[tableView selectedRowIndexes] indexGreaterThanIndex:idx]; } </code></pre> <p>}</p> <p>Ouput:</p> <pre><code> NSLog(@" 123 number %@",[tickTracker objectAtIndex:i]); Output: 123 number 2 NSLog(@" %li value ",row); 2 value </code></pre>

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.
