[Ironruby-core] Finding the mythical root_visual object in Gestalt

I can add the "root_visual" variable; the current implementation only defines "me" and "xaml", which do exactly what "root_visual" would do. Unfortunately the implementation doesn't quite match the spec at the moment (I'm not sure why they called it 1.0 =P).

Hi all,

I'm currently writing about Gestalt using the 1.0 release. The best documentation I can find for it is the PDF "sl-back-to-just-text.pdf", by Jimmy, which states:

"XAML accessors
root_visual maps to System.Windows.Application.Current.RootVisual ... When a method is called that does not exist on root_visual, then FindName(methodName) is called. This allows access to any XAML elements with an x:Name value...

root_visual.Message.Text = "New Message"

This is the code that I'm using to try and experiment with this:

<script src="<http://visitmix.com/dlr/dlr.js>http://visitmix.com/dlr/dlr.js" type="text/javascript"></script>

<script type="application/xml+xaml" width="200" height="50">
  <UserControl xmlns="<http://schemas.microsoft.com/winfx/2006/xaml/presentation>http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="<http://schemas.microsoft.com/winfx/2006/xaml>http://schemas.microsoft.com/winfx/2006/xaml" Width="200" Height="50">
    <Button x:Name="button1" Content="Button Text" />

<script type="text/ruby">
window.alert root_visual.button1.content


I cannot find this object placed anywhere I would expect; at least it's not as easily available as the documentation leads me to believe.

Can anyone throw some light onto what I'm doing wrong, or if there has been a change in the way this works?

Thank you kindly,
Adam Burmister
