Re: [MacRuby-devel] Visibility of ruby methods to objective-C delegates

      Hi Michael,

Could you try if the webview/js bridge part of the code works, or  
doesn't, in a normal MacRuby application? If it doesn't work, please  
file a ticket on https://www.macruby.org/trac/newticket. If it does,  
then it might be a HotCocoa problem, in which case please file a  
ticket here: http://github.com/richkilmer/hotcocoa/issues

Thanks,
Eloy

I'm trying to do something similar to this example:
http://code.reflectivepixel.com/post/103638573/require-hotcocoa-framework-we...
Code excerpt:
require 'hotcocoa'
framework 'webkit'
class Application
 include HotCocoa
 FULL={:expand => [:width,:height]}
 BASE=<<-END
   <html><head><style type="text/css">
   * { font-family: Monaco; }
   </style><script type="text/javascript">
   function say(arg) { window.TheBridge.click(arg);}
   </script>
   </head><body><h3>Ruby JavaScript Bridge</h3>
   <a href="#" onclick="say('hi')">tell</a></body></html>
 END
 def click(arg) #called from javascript
   root = document.createElement("div");
   root.innerHTML="javascript tells ruby: #{arg}"
   document.body.appendChild(root)
 end
 def document
   @web_view.mainFrame.DOMDocument
 end
 def self.webScriptNameForSelector(sel) #hide : in name
   sel.to_s.sub(/:$/,'') if is_available_selector?(sel)
 end
 def self.isSelectorExcludedFromWebScript(sel)
   ! is_available_selector?(sel)
 end
 def self.isKeyExcludedFromWebScript(key)
   true
 end
 def self.is_available_selector?(sel)
   ['click:'].include?(sel.to_s)
 end
 def start
   application :name => "MyBridge" do |app|
     app.delegate = self
     window :title => "MyBridge",
       :frame => [10, 620, 330, 230] do |win|
       win << @web_view=web_view(:layout => FULL) do |wv|
         wv.mainFrame.loadHTMLString BASE, baseURL: nil
         wv.frameLoadDelegate=self
         wso=wv.windowScriptObject #make visible to JS
         wso.setValue(self, forKey:"TheBridge")
       end
       win.will_close { exit }
     end
   end
 end
end
Application.new.start
Clicking on "tell" does not work. It seems, that the selector for  
"click:" is not found. When logging the selector values in  
self.isSelectorExcludedFromWebScript(sel), the "click:" selector is  
not amongst the results.
What am I missing here?
Regards,
Michael
