Returns OK or error.


Creates a new web view inside the window with the given placeholder control.
If you create WebKit 1.x view, you can use all the PDF/Image rendering functions, download delegate and callback functions, which don't work in WebKit 2.x.
But if you use WebKit 2.x, you can use script message handler or user scripts, which are not supported in WebKit 1.x.

The view is released automatically when window closes.
Web viewers created via WebView.Create or WebView.CreateWithControl are independent of FileMaker, so they don't reload with a record change. They also don't print with the layout and stay if you change the layout.

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.
