Hi There,
I used the notification like suggested and I still cannot display my
window.
This is my code:
-(void)applicationDidFinishLaunching:(NSNotification *)notification
{
printf("In Delegate method.\n"); //DEBUG
winCtrl = [[NSWindowController alloc] initWithWindowNibName:@"Window"];
[winCtrl showWindow:self]; //I have also tried [winCtrl showWindow:
[winCtrl window]];
}
I have no idea why this does not work, the DEBUG info is printed to
stdout and the rest of the code I use all the time so I am honestly
none the wiser. I believe the delegate method works otherwise the
text would not be printed to stdout but my second window will not
display like it is supposed to. I am at a loss.
Can anyone help?
Many thanks.
Phil.

Firstly I need a function to automatically run from a class used
in MainMenu.nib when the main.m calls NSApplicationMain();
The NSApplication object provides this facility:

-applicationDidFinishLaunching:
Sent by the default notification center after the application has
been launched and initialized but before it has received its first

You'll need to create that delegate object and hook it up to your
application object.
Also, I cannot figure out why when I initialize a window from a
nib or from a file before the call to NSApplicationMain() the
program crashes due to a memory leak.
Programs tend not to crash from memory leaks unless the leak is
large+long enough that you run out of memory.
I have tried to put the function in awakeFromNib but then the
window wont close itself from that function.
awakeFromNib is not the appropriate place for this.
