Re: Automatically Call a Function

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.
