Set background color to NSTableCellView

Question

I am trying to set the background color in an NSTableCellView, but there seems to be no way to do this.

For this, there must be another way to achieve this, which I do not know about, therefore, if someone could enlighten me, I would be very grateful!

Thanks!

Answer 1

A NSTableCellView is an NSView , and a NSView has a CALayer , and a CALayer has a backgroundColor . So that...

 myTableCellView.wantsLayer = YES; // make the cell layer-backed myTableCellView.layer.backgroundColor = [[NSColor redColor] CGColor]; // or whatever color you like 

Answer 2

You need to convert your NSColor object to a CGColor structure:

 self.layer.backgroundColor = [[NSColor redColor] CGColor]; 

Answer 3

for Swift 3, and based on Caleb's answer this works for me:

 cell.wantsLayer = true cell.layer?.backgroundColor = NSColor.red.cgColor 

It took me years to find this question and answer, and I am very grateful.
