Hi Cocoa developers, I have a small application that consists of a NSTabView, in which all tabs contain a single custom NSView. That custom view is layer-backed (setWantsLayer:YES in awakeFromNib).
So far, the view layer doesn't draw anything, and the NSView drawRect method fills its content with a opaque colour. Since the custom view fills its content with a background colour, I would assume that I can overwrite isOpaque to return YES. However, when I do so, there are artefacts that appear when I change tab. This behaviour goes away if isOpaque returns NO. From Apple's documentation: "A view object is opaque if it completely covers its frame rectangle when drawing itself." I would then assume it is the case for my custom view since its drawRect method fills the received rectangle with a plain colour. What I am not understanding properly here?
