问题
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
[appleMenu addItemWithTitle:[@"About " stringByAppendingString:appName]
action:@selector(orderFrontStandardAboutPanel:)
keyEquivalent:@""];
// Quit
[appleMenu addItemWithTitle:[@"Quit " stringByAppendingString:appName]
action:@selector(terminate:)
keyEquivalent:@"q"];
[appleItem setSubmenu:[appleMenu autorelease]];
}
At launch, my application gets the focus, but the menu bar is not clikable. However, if I click out the window and in again (giving the focus back to the application), it becomes clickable and working correctly.
Did I miss something?
UPDATE
This method is called when I'm creating the application as follows.
[UPDATE] This is what I'm starting my application with. It is actually called first thing from an ocaml binding outside any @implementation
of a class.
CustomApplicationDelegate* delegate = [CustomApplicationDelegate new];
[CustomApplication sharedApplication];
[NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
[NSApp activateIgnoringOtherApps:YES];
[[NSApplication sharedApplication] setDelegate:delegate];
[CustomApplication setUpMenuBar];
[[CustomApplication sharedApplication] finishLaunching];

Okay, thanks to the remarks of @bhaller I was able to solve my problem.
I actually transferred my calls to the delegate as follows.
-(void)applicationWillFinishLaunching:(NSNotification *)aNotification
{
[CustomApplication sharedApplication];
[CustomApplication setUpMenuBar];
[NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
}
-(void)applicationDidFinishLaunching:(NSNotification *)notification
{
[CustomApplication sharedApplication];
[NSApp activateIgnoringOtherApps:YES];
}

I had this issue and the reason was because my call to [NSApp activateIgnoringOtherApps:YES]
was in applicationWillFinishLaunching:
instead of applicationDidFinishLaunching:
.
As soon as I moved it, the menubar worked on first-launch.
