thank you. That seems to do the trick for the simple test App I created. After
creating IBOutlet and wiring it up in Gorm, I added the following at the end of
applicationDidFinishLaunching:
[mainWindow makeKeyAndOrderFront: self];
NSLog(@"the key Window: %@", [[NSApplication sharedApplication]
keyWindow]);
which spits out:
2024-08-29 11:49:14.793 Test5[72122:2615662661832] the key Window: <NSWindow:
0x2609f549008>Number: 4 Title: Test5 Window
However, that same approach doesn't work in my Document based app. I read
through David's "Cocoa Programming, Developers Handbook", and now I'm working
with ChatGPT as my mentor here, since never done that before, and don't have
any Mac programming experience ;)
What I told ChatGPT I want to do: MVC Document based app, that should have a
central .gorm file for menu and other central stuff, and then .gorm files for
each of different types of documents to be handled.
Now I ended up with:
* central .gorm file containing my menu, connected to an AppDelegate, that
loads the Gorm file.
* a DocumentController class (NSDocumentController subclass), which based on
what types of documents I want to create new, calls out one of my two Document
classes (NSDocument subclasses). To each of these NSDocument subclasses, I've
separate .gorm files.
Opening the Window with your approach works so far that the window opens, but
it doesn't become the key window:
With this in the makeWindowControllers method:
[characterWindow makeKeyAndOrderFront:self];
NSLog(@"THE KEY WINDOW: %@", [[NSApplication sharedApplication] keyWindow]);
it opens the Window, but logs:
THE KEY WINDOW: (null)
With above output, it's the only window (besides the menu), that the
application has, and it takes
input, but I wonder why the application doesn't even have a keyWindow at all?
I thought at least one should always be Key, and with that firstResponder, but
may have misunderstood?
ChatGPT insists on going through the topLevelObjects. But now, I'm not sure,
even if that works,
if it then would make the window key?
