How to change NSTextField background color in NSPopOver

Question

Mac OSX 10.10 Xcode 6.1

I created a tableview in NSPopOver. I try to

Answer 1

I really like @Prontto's solution but it does not work with NSImageView because it has no drawsBackground or backgroundColor.

Fortunately the appearance option works for image views as well!

cell.imageView?.image = image ?? nil
cell.imageView?.appearance = NSAppearance(named: NSAppearanceNameAqua)

Answer 2

There's a known bug with text fields and the "vibrancy" blending added in Yosemite. It's known to affect popovers.

The workaround is to set the appearance property of the table view to NSAppearanceNameAqua.

This was confirmed by an Apple engineer in their devforums.

This issue also sometimes affects NSTextFields that appear on popovers where the background is grey. Here's the Swift 5 fix, add this to the viewDidLoad() function of your popover controller

self.someTextField.appearance = NSAppearance.init(named: .aqua)

Answer 3

In my app, I had same problem. I used Swift and this worked for me. In your viewForTableColumn:

let cell = tableView.makeViewWithIdentifier(tableColumn!.identifier!, owner: self) as! NSTableCellView
    cell.textField?.drawsBackground = true
    cell.textField?.backgroundColor = NSColor.clearColor()
