Creating Sheets with RubyCocoa

Creating Sheets with RubyCocoa

Here’s another example from Tim Perrett; this one uses RubyCocoa to display a sheet in a window.

You can download a zip file here. After you unpack it, open and build the enclosed Xcode project.

The interesting Ruby code is in the MainController class, defined in MainController.rb.

Quoting Tim:

#  This class is instantiated in the MainMenu.nib file, and subsequently linked
#  up in IB to the main window (the mainWindow outlet) 
#  But, and this is a big but - its where I was going wrong for quite some time;
#  if you look in the secondary nib file, you can see that the panel nib's
#  file owner is this class but there it is not instantiated, but merely referenced
#  so IB is aware of its existence.
#  
#  I must give a shout to Sherm, the inventor of CamelBones (a perl/cocoa bridge) 
#  as he has been so so so helpful in getting this working using RubyCocoa.
#  I think this is one of the most important concepts when using IB, that of nibs 
#  with no instantiated class and its where a lot of people, including myself, 
#  go wrong.
#
#  Cheers everyone, Tim.
