Hi,
I went back to working on an old project that uses core graphics and I'm having problems getting it to run again.
The following code gives me an error with the graphics context:
def drawRect( rect )
return unless @controller
begin
@context = NSGraphicsContext.currentContext.graphicsPort
# Scale 15 min intervals to chart area
@xscale = bounds.size.width / 25.0
height = bounds.size.height
@yscale = height / 2.0
CGContextScaleCTM( @context, @xscale, @yscale )
CGContextTranslateCTM( @context, 0.5, 0.5 ) # Indent from bounds
# restore text size
CGContextSetTextMatrix( @context, CGAffineTransformMakeScale( 1 / @xscale, 1 / @yscale ))
show_index( height )
rescue => e
ErrorLog.instance.rescue_error( e )
end
end
unrecognized runtime type `{CGContext=}'

/Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/MacDriverLog.app/Contents/Resources/rb_main.rb:69:in `<main>'
line 55 is the first line:
@context = NSGraphicsContext.currentContext.graphicsPort
Has anything changed with regard to Quartz 2D drawing?
Thanks,
Bob Rice
