[MacRuby-devel] Using scripting bridge to create new objects within a Cocoa App.

[Kam Dahlin]

ScriptingBridge offers a couple of ways of creating objects. One is to use the generated classes and then just alloc/-init or -initWithProperties to create an object of that class type. 
The other is to use -classForScriptingClass on SBApplication to get the scripting class you want to create and then alloc/init to create an instance. The name of the scripting class can be found in the applications AppleScript dictionary. 

Once you have created an instance, it must be added to the proper container before it can be used. 

I would recommend reading the ScriptingBridge guide here: 
http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/ScriptingBridgeConcepts/Introduction/Introduction.html

As well as this Ars article:

I have wrestled a lot with SB. It gets you about 75% of what you need but that last 25% is a real PITA. 
Good luck and I hope this helps.
