When a popover shows, I'm curious whether it's possible to set the underlying settings on the popover's window, such as the window level. In my testing, popovers seem to be a window, but they doesn't respond to normal NSWindow
selectors, such as setLevel:
.
Is it possible to set the window level on a NSPopover
?
NSPopover
is a subclass of NSObject
, not NSWindow
, so setting the window level is not officially supported.
You could try getting the window like this:
NSWindow* popoverWindow = yourPopover.contentViewController.view.window;
I have no idea whether you can then successfully set the level though.
