Hi:
i'm the mad guy who made that VB code wich calls Funcitions from the HTML code :)
I'n new to Gambas, but from what I've read, it is possible to set up an Object Observer ...so why not intercept the webview control and do things BEFORE the Click event takes place?
Saludos
Martin

> Ahh, I got you wrong apparently... My answer can be applied if you have any
> occasion (event) to parse an (X)HTML element for this special attribute
> href="act:some_class.method". Then you can extract the class and method name
> and use Object.Call().
>
> You can (ab)use the WebView's Click event like this: Modify the <a> element
> to look like this:
>
> <a href="#act:some_class.method">some action</a>
>
> Then, when clicked, the WebView will load the valid URL (the anchor sign had
> to be prepended to make it valid - to trigger the Click event, in turn) and
> provide you a WebFrame object in whose Url property you have the wanted
> act:some_class.method string somewhere. Now parse and execute.
>
> I think it's too late for me to find clear words, so I attach a minimal
> example. (Note that the code is executed twice in this project which is
> certainly not desirable. You'll sure find a way to prevent this yourself.)
