[Rubycocoa-talk] Problems with creating bindings programatically in RubyCocoa

From: Alex S. <al...@al...> - 2007-08-04 17:42:03

Hi there,

I'm having some problems setting up bindings programmatically.

I'm trying to use a table with a (-) button in that removes it's row  
when clicked. The other table columns are bound to an  
ActiveRecordSetController, and the button column is unbound (is this  
right?). I then use setDataCell on the this column.

This is what I've tried:

	cell = OSX::NSButtonCell.alloc.init
  	  cell.objc_send(
  	  :bind,         "target",
  	  :toObject,     self,
  	  :withKeyPath,  "current_sale_controller",
	  :options,      {"NSSelectorName" => "remove" }
    )

	cell.setTitle '-'
    @remove_button_column.setDataCell cell

This doesn't give an error, but nothing happens when you click the  
button.

I think it could possibly be a problem with OSX::NSSelectorName not  
being a recognized constant, which is why I used the string instead.  
Am I on the right track here? Any pointers appreciated, I've searched  
google (a lot) before asking and I'm out of ideas...

Thanks in Advance,
Alex Speller

Hey Alex,

I think that what you want to do is to simply set the target of the
NSButton to the ActiveRecordSetController instance and use a selector
like #removeObject(obj) or #removeSelectedObjects() to tell the
controller to remove the object.

This is also how the + & - buttons work in the MailDemo sample.

Hope it helps :)

Cheers,
Eloy

Hi Eloy,

That worked! I guess I was barking up the wrong tree!

Cheers,
