NSTextView substructure does not display when drawsBackground = false

  • Add an NSTextView (either manually or through the interface builder).
  • Set drawsBackground = false
  • Add subview directly to NSTextView

Subview will not be visible.

However, if I add another subtitle to the same level as, for example, NSScrollView, the first preview will appear.

Here is an example project for Xcode: https://www.dropbox.com/s/inz30bq9xzdw0g5/TestTextSubviews.zip?dl=0

In the source code, if you uncomment the following lines:

// let bg2 = BgView (frame: NSRect (x: 105, y: 105, width: 100, height: 100)) //window.contentView.addSubview(bg2)

then the add-in will first appear.

I do not know the exact reason, but I suspect that this is a problem in the hierarchy of representations. I created a new project from the cocoa application template, added nstextview, and then added 1 and then 2 of your subviews - it seems to work as intended. Setting up a cocoa application template with a window controller and a view controller, so perhaps this correctly sorts the strangeness of the hierarchy view, which is not obvious from directly adding the view to the window in nib.

(NB: I'm on Xcode 7 beta right now, but I don't think this should matter)
