-====== WebView control ======
-//(Information and examples taken from the DroidScript documentation)//
-===== Description =====
-You can create a control to display local or remote web pages in your App using the **CreateWebView** method of the **[[built_in:app|app]]** object:
-<code>web = app.CreateWebView( width, height, options, zoom );</code>
-If you are loading remote web pages, then you might want to use the **SetOnProgress** method to set the name of a callback function that you want called to report the progress of loading the page.
-You can use the **LoadUrl** method to load an internal or external web page or the **LoadHtml** method to load text directly from within your App.
-<code> web.LoadUrl( url,options );</code>
-<code> web.LoadHtml( html,baseFolder,options );</code>
-Note: Using a WebView can be a good way of displaying colored and formatted text areas in your App. If you set the BackColor to a transparent color you can show formatted text over a background image.
-If you need to, you can use the **Execute** method to execute JavaScript code within the WebView.
-<code> web.Execute( text );</code>
-===== Methods =====
-Some controls use the same methods.\\
