A couple of things:
1. You’re keeping the panel window instance reference in
InspectorWindowController.sharedInstance, but not keeping a reference to its
window controller. That causes its window controller to be deallocated early,
although that likely has nothing to with the rest of the problem, since the
panel doesn’t have any custom behavior yet. You should keep a reference to the
window controller instead, and that will keep the panel alive too.
2. You’re doing a “performClose” to hide the panel. If you do an orderOut
instead, you get the behavior you want.
Note that you are getting a new instance of the panel because the window segue
mechanism decides the first one has disappeared. Again because it’s not
documented how window segues work, there’s no way of knowing what the “correct”
behavior is supposed to be. (Your panel window is correctly set to “Single”
mode in the storyboard, which is what’s supposed to prevent multiple instances
Also undocumented — forever AFAIK although others on this list may know more
about this — is what a window “close” (or “performClose”) does, other than
ordering out the window and (if it’s set to release on close) to release it.
Whatever a “close” actually does, it’s making the storyboard mechanism unable
to find the panel instance, so it creates a new one. (Your panel is *not* set
to release on close, and I was able to verify that it’s not being released
regardless, so this is not anything you appear to be doing wrong.)
