I'm running into a bit more trouble than I expected trying to implement
a multiple window per document app.
I have a "main" window for my document and several secondary windows.
The main window is created and managed as usual (it comes from the
documents nib file). The secondary windows are handled in a method of
my NSDocument subclass like this:
NSWindowController* aWindowController = [[NSWindowController
alloc]initWithWindowNibName:@"Subwindow" owner:self];
[self addWindowController:aWindowController];
[aWindowController showWindow:self];
First problem: The documented default behavior for a document with
multiple windows is that the document remains open until the user
closes the last window.
<
http://developer.apple.com/documentation/Cocoa/Reference/
ApplicationKit/ObjC_classic/Classes/NSWindowController.html#//
apple_ref/doc/uid/20000031/BAJDBCHC>
But this is not what I'm seeing. I can close all the windows and the
document stays open.
I worked around this problem thusly:
[mainWindowController setShouldCloseDocument:YES];
This gives me the behavior I'm after (closing the main window closes
the doc, closing a secondary window does not) but I'm uneasy. It
doesn't seem right that I should have to do this as it is in conflict
with the docs.
Second problem:
Closing the main window closes the document, but the secondary windows
remain open. This also seems wrong as I expected to get the proper
behavior "for free".
Either my expectations need adjustment or I am doing something wrong. I
suspect the latter.
Any help appreciated.
