[Rubycocoa-talk] Rubycocoa and the Webkit: Javascript calls a rubyfunction

[Stefan B. <ste...@gi...>]

Hi all,

i am still having problems with the WebKit option where i can have Javascript call Cocoa functions.
Does anyone have a working RubyCocoa example of how to implement this?
In the snippet below for the "isSelectorExcludedFromWebScript"-method, i don't even see the function i called, but generic functions.  
If i could implement "invokeUndefinedMethodFromWebScriptwithArguments" that would be nice, but no real way of knowing what kind of parameters i have to put in the objc_class_method.



Part of class which shows the webpages (that works)
...
scriptobject = currentwebkit.windowScriptObject()
scriptobject.setValue_forKey(self,  "qi3jsobject")
homeurl = "somekindofurlwithawebpageandjavascript"
currentwebkit.setFrameLoadDelegate(self)
...

part of class with the implemented methods required by Webkit (My source is: http://www.thimbleby.net/script )

...
	objc_class_method 'isSelectorExcludedFromWebScript', [:BOOL , :sel]
	def self.isSelectorExcludedFromWebScript(selector)
		# This does NOT show the functions i called 

		OSX::NSLog("Check if #{selector} is allowed!!")
		return true; 
	end
	
	objc_class_method 'isKeyExcludedFromWebScript', [:BOOL , :char]
	def self.isKeyExcludedFromWebScript(name)
		OSX::NSLog("Key excluded is #{name}")
		return true; 
	end
	
	objc_class_method 'webScriptNameForSelector', [:id , :sel]
	def self.webScriptNameForSelector(selector)
		OSX::NSLog("Check name for #{selector}!!")
		return "nicerFunctionName"
	end
	
       # No clue how to implement this method (NSString and NSArray as parameters??)
	#objc_class_method 'invokeUndefinedMethodFromWebScriptwithArguments', [@@: , @@:]
	#def invokeUndefinedMethodFromWebScript_withArguments_(name, args)
	#	OSX::NSLog("Check invokeUndefinedMethodFromWebScript for #{name}!!")
		
	#	puts name
	#	puts args.inspect
	#end

...

and in javascript i did this:

qi3jsobject. nicerFunctionName("oh yes!");


I wish i could port this to MacRuby but it's rb-appscript support is missing and it's  appleevent support is not ripe for production...

Kindly,

Stefan
