Description

Returns the Window Reference for a window specified by the Index parameter.
The Window Reference is a unique ID handed out by the operating system. It is used by the rest of the WebView functions Caution: Passing 0 for Index will grab the front most window which should be your FileMaker window, but it could be any window including dialogs. This is a particular problem with the "Data Viewer" which is always in the front. Window.FindByTitle was added to version 1.1 as a more reliable way of getting the Window.Ref.
The window reference is only valid until the window is closed.

Note for Windows: For Windows this function is only supported in FileMaker Pro when using Internet Explorer as engine behind the Web Viewer, but not when Microsoft Edge/Chrome engine is used. But the functions should still work if with Web Viewers created via plugin using WebView.Create and WebView.CreateWithControl as those still use Internet Explorer.
