So, if the button is pushed to bring up a new window, the IBAction
is in
the master window controller. But the actual adding of the
NSWindowController and its associated window should be done by a
method
back in MyDocument.
I can't find description of this part of the process.
The action in the existing window controller can create a new window
controller, then invoke [self.document addWindowController:
newWindowController]. That's all it should take.
Or, if the document needs to create the new window controller itself
for some reason, implement the action to create the new window
controller in your document class instead, and invoke [self
addWindowController: newWindowController].
Note that the document and the window controllers are all effectively
in the responder chain, so sending the button action to First
Responder instead of a specific object will send the action to
whichever object implements it.
One way I can think
of to do it is as follows:
In my MasterWindowController, have an instance variable called
something
like "createdby", and a method "setCreatedby". Then in MyDocument,
when I
alloc and init the instance of the masterWindowController, I follow
directly with [masterWindowController setCreatedby:self].
Window controllers already have a "document" outlet that is
automatically set by [NSDocument addWindowController]. You don't need
to roll your own.
