nsapplication

I'm currently trying to get the path of a file from a drag and drop operation inside of a custom view, and then pass that path to my app delegate. I'm currently using the following: - (BOOL)performDragOperation:(id <NSDraggingInfo>)sender { NSPasteboard *pb = [sender draggingPasteboard]; NSString *type = [pb availableTypeFromArray:[NSArray arrayWithObject:NSFilenamesPboardType]]; NSArray *array = [[pb stringForType:type] propertyList]; //access the app delegate NSApplication *myApplication; myApplication = [NSApplication sharedApplication]; [myApplication uploadFiles:array]; return NO; }

When I learned how to start NSApplications on my own, the code I used (based on here and here ) did [NSApp activateIgnoringOtherApps:YES]; which forces the app to the front at startup. I'd like to know what most other apps do. I want to be able to run programs both directly from the binary and from an app bundle, and I'm not using Xcode to build this (raw building). So I'd rather this act naturally, so to speak. The docs do say Finder issues NO , but... why Finder? Isn't this a method that's run from within the process, not outside? (I'm not in control of the choice.) And what about the Dock

I'm trying to use the objc_getProtocol() function to get a reference to the struct representing the NSApplicationDelegate protocol: Protocol *protocol = objc_getProtocol("NSApplicationDelegate"); However, for some reason, this always returns NULL . Other protocols such as NSObject , NSCoding , NSTableViewDelegate , and NSTableViewDataSource work fine. Is there something special about NSApplicationDelegate , or am I doing something wrong? Found the answer in the Apple docs: http://developer.apple.com/library/ios/#DOCUMENTATION/Cocoa/Conceptual/ObjectiveC/Chapters/ocProtocols.html#//apple_ref

I am developing Mac desktop application, where i am capturing the screen using CGImageRef screenShot = CGWindowListCreateImage(CGRectInfinite, kCGWindowListOptionAll, kCGNullWindowID, kCGWindowImageDefault); and display the screen shot, The problem is, i am expecting it should show the mouse cursor too, but its not showing, do i need to enable any settings for that ? I tried following before calling this function CGDisplayShowCursor(kCGDirectMainDisplay); CGAssociateMouseAndMouseCursorPosition(true); but it didn't work, When i checked using following bool bCursor = CGCursorIsDrawnInFramebuffer

I'm building a menu bar in my cocoa application with the following code in the @implementation of my custom application CustomApplication : +(void) setUpMenuBar { [CustomApplication sharedApplication]; // Main menu NSMenu* mainMenu = [NSApp mainMenu]; if (mainMenu != nil) return; // We set it already mainMenu = [[[NSMenu alloc] initWithTitle:@""] autorelease]; [NSApp setMainMenu:mainMenu]; // Application menu NSMenuItem* appleItem = [mainMenu addItemWithTitle:@"" action:nil keyEquivalent:@""]; NSString* appName = @"MyApp"; NSMenu* appleMenu = [[NSMenu alloc] initWithTitle:@""]; // Apple menu
