I have an NSTableView, and I would like to know when the user has scrolled to the bottom, so I can perform an action. Not quite sure how to go about this? UPDATE: Here is how I am calculating the bottom of the table: -(void)tableViewDidScroll:(CPNotification) notification { var scrollView = [notification object]; var currentPosition = CGRectGetMaxY([scrollView visibleRect]); var tableViewHeight = [messagesTableView bounds].size.height - 100; //console.log("TableView Height: " + tableViewHeight); //console.log("Current Position: " + currentPosition); if (currentPosition > tableViewHeight - 100)

I'm using the "Alternating Rows" option in Interface Builder to get alternating row colors on an NSTableView. Is there any way to change the colors of the alternating rows? If you want to use an undocumented way, make a NSColor category and override _blueAlternatingRowColor like this: @implementation NSColor (ColorChangingFun) +(NSColor*)_blueAlternatingRowColor { return [NSColor redColor]; } @end or to change both colors, override controlAlternatingRowBackgroundColors to return an array of colors you want alternated. @implementation NSColor (ColorChangingFun) +(NSArray*

I am fairly new to OS X Cocoa programming but have decided to give it a go with the new Swift language. I have an NSTableView with 1500 rows (will be more) and 7 columns. There is one checkbox column and the rest are text fields, one with a date formate and one a currency formatter. I first set this up as cell based. Scrolling was buttery smooth (I even did a test adding 1 million rows, still smooth). This was under mavericks. I then upgraded to Yosemite , scrolling performance significantly degraded. Enabling Core animation layer checkbox on the table view improved this but was still worse

I have asked this question once before, but I'm just not very satisfied with the solution. Automatically adjust size of NSTableView I want to display a NSTableView in a NSPopover , or in a NSWindow . Now, the window's size should adjust with the table view. Just like Xcode does it: This is fairly simple with Auto Layout, you can just pin the inner view to the super view. My problem is, that I can't figure out the optimal height of the table view. The following code enumerates all available rows, but it doesn't return the correct value, because the table view has other elements like separators,

I'm trying to subclass NSCell for use in a NSTableView. The cell I want to create is fairly complicated so it would be very useful if I could design it in Interface Builder and then load the NSCell from a nib. Is this possible? How do I do it? The question was about a subclass of NSCell; the other answers seem to be doing something else, likely taking advantage of UITableViewCell being a view. NSCell is not a view. While laying a custom cell out in IB would be a useful thing to be able to do, I think the answer is basically "no, this is not possible". When you subclass NSCell, you're pretty

Standard highlighting color in OS X applications is blue. Is it possible to change it to another color, e.g. gray? Note that I am using the new view-based NSTableView available starting from OS X 10.7. Since you're using the view based NSTableView, you can subclass NSTableRowView, feed it to the table delegate method - (NSTableRowView *)tableView:(NSTableView *)tableView rowViewForRow:(NSInteger)row; , then customize your selection in the row view class. Here's an example: - (void)drawSelectionInRect:(NSRect)dirtyRect { if (self.selectionHighlightStyle != NSTableViewSelectionHighlightStyleNone
