Description

Creates a new window with a web viewer.
The window is initially invisible, so you can finish setup and then call Window.Show function.

The returned identifier can be used with our WebView functions as well as our Window functions.

Uses WebView2 on Windows, just like FileMaker's WebViewer since version 19.3 and WebKit 2 for macOS.

This WebView supports the fmp:// URLs to trigger scripts. You can use FileMaker.PerformScript just like FileMaker's web viewer. For FileMaker.PerformScriptWithOption the option can be 1 for halt, 2 for exit, 3 for resume, 4 for pause. 0 is pause instead of continue and 6 is resume instead of Suspend and Resume since the plugin can't do these modes.

e.g. trigger a script:

FileMaker.PerformScript( "Script name", "Optional Parameter");

You can use FileMaker.Evaluate to directly evaluate something from JavaScript. e.g. query a get function like this:

let filename = await FileMaker.Evaluate('Get(FileName)');

Examples

Create a web window:

Set Variable [ $web ; Value: MBS("WebView.CreateWindow"; 200; 200; 500; 500) ]
Set Variable [ $r ; Value: MBS("WebView.LoadURL"; $web; "https://mbsplugins.de/filemaker") ]
Set Variable [ $r ; Value: MBS("Window.SetTitle"; $web; "MBS Website") ]
Set Variable [ $r ; Value: MBS("Window.Show"; $web) ]
