[Mono-osx] Global Objects

[Fischer Tobias]

Hi,

you could implement your global object as a singleton.
Then you could access your instance from everywhere you want.

Here a small example of a singleton implementation and usage:

Singleton:
public class Foo
{
	private static Foo _instance = null;

	public static Foo Instance()
	{
		if (_instance == null)
		{
			_instance = new Foo();
		}
		return _instance;
	}

	public void DoSomething()
	{
		...
	}
}

Usage:
public class Bar
{
	public void Compute()
	{
		Foo.Instance().DoSomething();
	}
}

Hope that helped.

Best regards,
Tobias

How do I declare global instances of objects?

When using C# and .NET I would do something like this:

public static program {
  public static Foo MyFoo = new Foo();

  static void main() {
    MainForm = new MainForm(MyFoo);
  }
}

however with Mono/MonoMac the main function calls NSApplication.Main and
doesn't directly create any windows. How would I pass an instance of
MyFoo to the main window?

Note: I am trying to avoid any references to MainClass in my
windows/window controllers as that creates a tight coupling. I want to
reuse the window classes in other situations hence the desire for loose
coupling.

Is what I want possible with MonoMac?

thanks, Andy
