I don't know if you've seen this but it might help.

Im still getting no where with this one. Help.
This is a document based application, so the NSWindowController stuff
is a
little more complicated.
1. I can't get a preferences panel to display. I created a preferences
panel in IB, and made its file owner "Preferences". I have a
Preferences.m
and Preferences.h file in my Xcode project. I created an outlet for a
NSWindowController (preferencesPanelController), and an outlet for a
NSPanel (preferencesPanel) and connected them via IB in the Preferences
NIB, and the preferences menu option in my MainMenu NIB.
(follow-up: I have checked, double checked my connections. I looked at
the
developer example TextEdit that has a preferences panel, and the
"accessory" window example in my Learning Objective-C with Cocoa book).
So, when I try to open the preferences via the menu option, I see that
my
method is called; "showPanel called" is printed, but the panel never
appears. I don't get an error, I have tried inside and out of the if()
statement checking if the preferencesPanelController has been
instantiated, and the NSLog shows a healthy NSWindowController object.
My Preferences.nib file lives in the same directory in the project as
the
MainMenu.nib file, and I never get an error that the NIB failed to
load.
Here is the showPanel code that I have connected to the "Preferences
..."
menu option
- (IBAction)showPanel:(id)sender
{
printf("showPanel called\n");
if(!preferencesPanelController)
{
if (![NSBundle loadNibNamed:@"Preferences" owner:self])
{
NSLog(@"Failed to load Preferences.nib");
NSBeep();
return;
}
preferencesPanelController = [[NSWindowController alloc]
initWithWindow:preferencesPanel];
NSLog(@"preferencesPanelController %@",
preferencesPanelController);
}
[preferencesPanelController showWindow:self];
}
Could this be opening offscreen?? There is simply no errors generated,
and
this code on the first call prints this
showPanel called
2004-07-16 12:26:27.888 MOViewer[557] preferencesPanelController
<NSWindowController: 0x147c9d0>
and on subsequent calls I get just this
showPanel called
All is normal, EXCEPT THAT THE WINDOW NEVER IS DISPLAYED! Ahhh. I have
spent a lot of time trying to figure this one out. I may just start a
test
project to see if I can write code to make any window appear. The
examples
work fine, but I can't find the difference between their code and mine
(either in Xcode or IB).
What am I missing?!
Thanks
Albion
