As a final experiment, in my Matrix class I overrode initWithFrame……
and as the first and only line of the override had this:
BOOL f = [super isFlipped];
Lo and behold it returned YES which is definitely not the default.
I stopped the execution.
So from this I conclude that NSMatrix IS flipping t

The object you created has an inset of 40, and since NSMatrix organizes its
cells from the top left, that is what you are seeing, regardless of whether or
not NSMatrix returns YES for -isFlipped. If this is a matter of personal
discovery, override -isFlipped in your class and have it return NO t

That's not what I asked. I asked for the frame.

Thank you for answering

Here once again is the code I posted
NSWindow *theWindow = [aController window];
NSView *theContentView = theWindow.contentView;
NSRect theContentFrame = theContentView.frame;
NSRect theMatrixFrame =

What’s _theMatrix’s frame? It could either have an origin that puts it at the
top, or it could draw its content in its upper-left
Probably more to do with the NeXTSTEP/OPENSTEP ancestry. Those used Display
Postscript with the origin being the bottom left.

Yes, you're right it was because of PostScript, although you'd chose to an

Yes, Quartz changed it to be bottom left for some crazy reason - maybe just to
be different and upset off the Carbon developers of the
What I believe you're wanting to know is that cells in a matrix have their
row-column coordinates start from the top left, so the cell at (0,0) is in the
top left of its enclosure matrix and the cell at row 1 column 0 is below it.
