Folks;
This one is driving me mad!
I'm trying to bust up an overly complicated xib into 2 xibs - the main xib and
a preference xib
I've started completely over trying to implement a pref xib -- no CoreData just
bare bones….
I have created a brand new subclass of NSWindowController: Pref2Controller
there is not a single line of code in this object nor any instance
variables.
I have created a brand new xib file: ptest
XCode creates the xib with a FilesOwner, FirstResponder, Application,
and Window (set to releaseOnClose and visibleAtLaunch)
I have set the FilesOwner to be an instance of Pref2Controller (using IB)
I have set the window outlet of the FilesOwner to point to the NSWindow object
(using IB)
These two are the only changes I've made to ptest.xib
When I use this code in the appDelegate:
- (IBAction) configure:(id)sender {
if (!prefPanelController) {
prefPanelController = [[Pref2Controller alloc]
initWithWindowNibName:@"ptest"];
}
[prefPanelController showWindow:sender];
}
The new ptest.xib window will open once but never again if I close it.
this is true regardless of whether I set the window to releaseOnClose
or not
this is also true regardless of whether I have hooked up the window
outlet or not
logging [pController window] shows (null) regardless of whether
I have outlet assigned or not
as well as regardless of whether prefPanelController already
exists or has just been alloc'ed and init'ed..
What I am just not understanding here?
Please?
