Re: Is it possible to set an NSTableView cell background color?

[David Delmonte]

I worked the problem. I’m rather rusty these days.

This is what I came up with:

1. Moved to view-based table view.

2. In viewForRow, I added this line:

 cell.memoryName.drawsBackground = true

3. And then:

 cell.memoryName.backgroundColor = mintGreen

Thanks to all for the pointers.

How did you get it to compile?  It requires a view based tableview. Your first 
step is to convert to a view based tableview.

In that case, you need to implement the delegate method 
"tableView(_:willDisplayCell:for:row:)”, which is called once for each cell 
that’s redrawn.

In your method, you need to verify that the cell is of the type you expect (a 
NSTextFieldCell, I’m guessing), cast it to the correct type, and then set its 
backgroundColor property. Note that NSCell does not itself have such a 
property, it’s only implemented by specific subclasses.

Alternatively, it is possible to prepare one cell per color at initialization, 
then supply the correctly colored cell at each row/column. This is slightly 
more efficient, because it doesn’t involve re-configuring the cell each time 
it’s used, but it’s a bit more code (also in the delegate).

I tried you solution but it doesn’t color the cell. Scratching my head some 
more.. I’ll probably ask on Stack Overflow.

NSCell-based or NSView-based?

[Saagar Jha]

Well, assuming you have a NSTableCellView, you can set its background color 
using its layer. For example:

cell.layer.backgroundColor = NSColor.black.cgColor

Is it possible to set an NSTableView cell background color?

[David Delmonte]

Hi all, I have a table that has records by date. I want to color those entries 
based on the decade.

I cannot seem to find a way to do this.

Any help would be appreciated.
