> What is the best way to handle double-clicked files in an application that doesn't use documents? The reason I ask is because a project I'm working on, PCSX-R, currently uses NSDocument subclasses to handle opening of files double-clicked in the Finder. However, the readFromFileWrapper:ofType:error: function returns NO even if the file is loaded to prevent the document window from popping up (I have it se with no close buttons; the window is called modally), but it shows an error that the file wasn't opened, despite it being so. Should I use a different way of managing double-clicked files, or is there a function that I should overload on my NSDocument subclass?

Hi,
not sure if understand your question.
I am assuming
1. you want program to start from double click of document file
2. you want to be able to open program by clicking application file but do not want the app to open an empty document window.
Create a document based application.
Create an application delegate file
// MyApplicationDelegate.h
#import <Cocoa/Cocoa.h>
@interface MyApplicationDelegate : NSObject <NSApplicationDelegate> {
}
@end
// MyApplicationDelegate.m
#import "MyApplicationDelegate.h"
@implementation MyApplicationDelegate
- (BOOL)applicationShouldOpenUntitledFile:(NSApplication *)sender {
return NO;
} // end applicationShouldOpenUntitledFile
@end
In mainMenu.xib link the application's delegate outlet to MyApplicationDelegate
And that's it.
