How to return value from gui window function?

Code (csharp):

1.     void MenuAreYouSure () {
2.         windowRect = GUILayout.Window (0, windowRect, WindowAreYouSure, "Are You Sure?");
3.     }
4.    
5.     void WindowAreYouSure (int windowId) {
6.         if(GUILayout.Button ("YES")){
7.             Application.Quit();
8. //HOW TO RETURN SOMETHING FROM HERE TO THE ABOVE MENUAREYOUSURE() function?
9.         }
10.         if(GUILayout.Button ("NO")){
11.             menuSelected = MenuMain;
12.         }
13.     }

Ive the above code, and a lack of c# knowledge. My question is, how would i return a bool value for instance from the bottom window function to the above menu function?

 

if you want to share a boolean, just declare it outside the function:
boolean myValue = false;

 

Sure thats an option, but id also like to know if theres an easy c# way of doing this.

 

Well, Appels' version _is_ the easy way to do it.

I want to bump this thread because I need to know what the title asks: How can you get a return value from the func parameter of GUI.Window? I want a static function that can define a window and return values. It's going to be a file browser called from multiple scripts.

This needs to be a custom file browser implementation, so existing solutions won't work –*though I would love to see some source, if possible.
