Subject: Re: Advanced rubycocoa: full-screen applications? (Can I access CoreGraphics calls?)

Hi Fujimoto-san and Kimura-san,

Thanks to your help, I was able to get my application to go full- 
screen with no menubar or dock visible.

I think the problem I was having was that I was trying to write a  
Ruby program that used Cocoa libraries.  I was using all the right  
calls, but I couldn't get rid of the menubar or dock.  I used  
TMPresents as an example, and changed how I was doing things.   
Instead of a Ruby application, I made it an objective C application  
that used Ruby classes.  Once I did that, I was able to go full-screen.

However, I'm having another problem.  My application is crashing, and  
the error is somewhere in the Ruby libraries, not directly in my  
code.  Here's the program output:

2006-01-10 03:31:04.506 NRFApp[918] NRFView(0x60dba0) - NSView not  
correctly initialized. Did you forget to call super?

correctly initialized. Did you forget to call super?

NRFApp has exited due to signal 6 (SIGABRT).

Another run went like this:

I've tried to debug the program using the XCode debugger (GDB  
underneath) but I only get assembly output.  I guess the problem is  
that something, either Ruby or the RubyCocoa libs were built without  
debugging symbols, or stripped.  Unfortunately, I can't seem to  
rebuild these properly to get debugging symbols, so I'm unable to  
debug what's happening.

Can anybody help me understand how to debug and fix this problem?  If  
I can't get it working with RubyCocoa soon, I might have to give up  
and write it in Objective-C (and I don't know Objective C!

Thanks,

Ben
