You need to know which object is being called when the condition is met, and that object has to have a pointer to your window so it can call it. Generally you’d wire a connection in Interface Builder from that object to your window, so the object will have an instance variable pointing to the window.
In a simple app the object that’s doing stuff is most likely the application delegate object, so you’d add an instance variable of type MYWindow*, put the IBOutlet keyword on it so IB knows it can be wired to, and then control-drag a connection from the window to the app delegate. Now when a method of the app delegate is called (like some menu-triggered action) it can use that instance variable to call the window.
