[Rubycocoa-talk] publish members in Ruby class to ObjC

[Motohiro T. <mo...@gm...>]

Hi,

I want to publish some member variables in Ruby class to Objective-C.
How can I do that ?

in QuartzComposer framework, member named "input***" in custom class
are automatically detected at runtime, like this:

@interface MyCustomPatch : QCPatch
{
    QCStringPort *inputFoo;
}

I wrote Ruby class like:

class MyRubyCustomPatch < OSX::QCPatch
  attr_accessor :inputFoo
 ...
end

but "inputFoo" is not detected.

I tried to wrote *.h for MyRubyCustomPatch class in Objective-C to
publish inputFoo, but it was no use...


sorry for my continuous posts. m(_ _)m

This is unfortunately not supported yet :(

However, I don't really know QCPatch, but is it really necessary to  
provide instance variables in the superclass? This looks weird and  
unusual. Generally in superclasses you provide methods but not  
instance variables.

Do you have a pointer to the mechanism behind QCPatch and this  
instance variable stuff? I could not find on google.

Thanks,
Laurent

I feel too :)

I don't have any resources to grub QCPatch design cause that is not
publicized by Apple ;)
Everything I know so far is a collection of lots of web searches and
observations of QuartzComposer behavior.It seems the QuartzComposer
framework collects all ports by their names (prefixed by input/output)
when a QCPatch instance is initialized.

Anyway, If adding/removing ports at any runtime is available by some
API, that will be enough for me. I will try digging more.

Cheers,
