Cocoa应用程序菜单栏不可点击 [英] Cocoa application menu bar not clickable

问题描述

我在我的可可应用程序中使用以下代码在我的自定义应用程序的 @implementation 中创建一个菜单栏 CustomApplication ：

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]];
}

在启动时，我的应用程序获得焦点， 。
然而，如果我点击窗口，并再次（将焦点移回应用程序），它变得可点击，并正常工作。

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.

什么？

UPDATE

这个方法在我创建应用程序时被调用如下。
[UPDATE] 这是我开始我的应用程序。它实际上是一个类的 @implementation 之外的ocaml绑定的第一件事。

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];

推荐答案

好吧，感谢@bhaller的话能够解决我的问题。

Okay, thanks to the remarks of @bhaller I was able to solve my problem.

我实际上将我的电话转移到委托如下。

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];
}
