Cocoa predefined sized mouse cursor?
Is the mouse cursor with Preview resizing (for example, when resizing shapes) the system cursor?
It is not directly available as a method in NSCursor
, but then it doesn't look like there is a private resource for the cursor in the Preview app bundle.
Are there any other system cursors besides the methods defined by the NSCursor
.. class ?

I think you are especially interested in these class methods (Preview.app dissasembly).
+[NSCursor resizeAngle45Cursor]; which calls +[NSCursor _windowResizeNorthEastSouthWestCursor];
+[NSCursor resizeAngle135Cursor]; which calls +[NSCursor _windowResizeNorthWestSouthEastCursor];
According to AppKit disassembly, these are private methods of NSCursor.
You can try it in your code for example.
(void)mouseDown:(NSEvent *)theEvent
{
[[self window] disableCursorRects];
id cursor = [[NSCursor class] performSelector:@selector(_windowResizeNorthEastSouthWestCursor)];
[cursor push];
}
There are more undocumented cursors like
+[NSCursor _helpCursor];
+[NSCursor _zoomInCursor];
+[NSCursor _zoomOutCursor];
and many others
