I hope someone can put me straight. I created a vanilla Cocoa App. I deleted
the window from the MainMenu.xib and created a MainWindow.xib with essentially
an identical window (no views).
I created a MainWindowController with one overriding method, init, see below.
In the app delegate's applicationDidFinishLaunching method I create the main
window controller and attempt to show the main window. If I breakpoint just
after the [mainController showWindow: nil] method I can see the proper user
interface with the main menu and main window. However, when I let the program
run the window immediately disappears. As none of my code runs after that point
I'm at a bit of a loss discovering what makes the window go away.
What am I doing (or not doing) that causes the main window to close or become
invisible? The code is below.
Thanks,
Tom Wetmore
AppDelegate.h:
--------------
@interface AppDelegate : NSObject <NSApplicationDelegate>
@end
AppDelegate.m:
--------------
#import "AppDelegate.h"
#import "MainWindowController.h"
@implementation AppDelegate
- (void) applicationDidFinishLaunching: (NSNotification*) aNotification {
MainWindowController* mainController = [[MainWindowController alloc] init];
[mainController window]; // force controller to load nib.
[mainController showWindow: nil]; // show window -- which promptly
disappears
}
@end
MainWindowController.h:
-----------------------
@interface MainWindowController : NSWindowController
@end
MainWindowController.m:
-----------------------
#import "MainWindowController.h"
@implementation MainWindowController
- (id) init { return [super initWithWindowNibName: @"MainWindow"]; }
@end
