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

[demallien <dem...@me...>]

Hi Stefan,

I don't have a Mac in front of me to test, but I noticed that -invokeUndefinedMethodFromWebScript:withArguments: isn't a class method, it's an instance method of the WebScripting protocol, so you should just be able to do declare this:
def invokeUndefinedMethodFromWebScript_withArguments_(name, args)
  OSX::NSLog("Check invokeUndefinedMethodFromWebScript for #{name}!!")
  puts name
  puts args.inspect
end

as a method on the object that you set using setValue:forKey:

Your two class methods shouldn't actually need to be defined - they default to returning YES anyway.

Anyway, try that, and let us know if it helps....

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 selfisKeyExcludedFromWebScript(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
