macOS What object to place for manually drawing gradients on?

[MythicFrost]

Hi,

I'm wondering what object do I place so that I can manually (from code) draw a gradient over it. I had a look at an Image Well in IB, and searched for NSImageView in the documentation and it didn't seem to have any events that I could use to draw on it, I just want a static control I can draw on the background of.

In fact, I need to be able to do the same thing on buttons, and windows as well. Is this possible?

Same as any other custom drawing: subclass the class (or NSView) and override drawRect:

That whole entire document is a must read for people overriding NSView classes. (Overkill, probably, but its got some real useful info on how Quartz works.
