Modal Dialog

Hello, everyone! I wanna to write a function that show a dialog window, the only method i thought about is that defining a global boolean variable to record whether we are showing a gui, if so, i must maintain its value when i or my partner is showing a gui! Are there any other method? i find a way here : link text

but it is in javascript version, can anybody translate it into C# version? Thanks in advance! static function ModalWindow(rect:Rect,title:String,windowFunction:Function)

{

 return GUILayout.Window(GUIUtility.GetControlID(FocusType.Passive),rect,function(id:int)

 {

     GUI.depth=0;

     //first get a control id. every subsequent call to GUI control function will get a larger id

     var min=GUIUtility.GetControlID(FocusType.Native);

     //we can use the id to check if current control is inside our window

     if(GUIUtility.hotControl<min)

         setHotControl(0);//if it's not - set hot control to 0, to allow window controls to become hot

     //if it is, we can't change it, because mouseover effect would not be there

     

     //draw our window

     windowFunction();

     

     //get max control id in our window

     var max=GUIUtility.GetControlID(FocusType.Native);

     //once again check current hot control

     //if it's outside our window - set it to -1 - it prevent's clicks!

     //we can't block clicks inside our window, so we have to check max!=-1

     //max equals -1 if a control inside our window has taken focus in this frame, because

     //we can't get a valid id in this frame any more

     if(GUIUtility.hotControl<min || (GUIUtility.hotControl>max && max!=-1))

         setHotControl(-1);

     

     //focus the window and bring it to front

     GUI.FocusWindow(id);

     GUI.BringWindowToFront(id);

 },title);

}

static function setHotControl(id:int)

{

 //don't block events if mousePointer is outside "Screen", otherwise if we run the game in editor

 //we would block the editor GUI as well.

 if(Rect(0,0,Screen.width,Screen.height).Contains(GUIUtility.GUIToScreenPoint(Event.current.mousePosition)))

     GUIUtility.hotControl=id;
