Re: How project center create the app delegate?

[Eric Wasylishen]

Hi Omar,

This confused me as a beginner as well. The AppController object is probably instantiated in the application's main nib/xib/gorm file (probably MainMenu.gorm), and it is set as the application's delegate by a connection made in Gorm/InterfaceBuilder. 

So, you have a sequence of events like this:

-main() calls NSApplicationMain

-the application's Info.plist is parsed and the main nib file listed there is loaded

-the nib usually contains an application delegate object, which is connected to the delegate outlet of the NSApplication object

- your delegate's methods such as applicationWillFinishLaunching should now get called

Hope this helps

Eric

Hi all,

 After a few months of first discovering GNUStep, I finally decided to read some tutorials on it, to really learn more about it. I am currently reading about the shared application object and its delegate. According to the tutorial, I create an object and implement some methods that control the app's behaviors, such as, 

- (void) applicationWillFinishLaunching: (NSNotification *)not

and then set this object as the application's delegate using [NSApp setDelegate]. So I created a new project in ProjectCenter, to see how this works in the default project template. It seems that the application delegate is an instance of a class called AppController, implemented in AppController.m. There is also a main source file which calls NSApplicationMain(). However, I can't seem to find any place in the code where this class is instantiated and set as the application delegate. So, where does ProjectCenter set this up? How does the program know which class it needs to set as the app delegate? Thanks for any info.

Sincerely,

Omar Campos Rivera
