Hi Robert, Can you try: def knowsPageRange(range_ptr) range_ptr[0] = NSMakeRange(1, 1) true end This method is called with a pointer to an NSRange structure and you're supposed to set it to something in case you return true. In C, it would have been: *range_ptr = NSMakeRange(1, 1) Doing range[0].location=1 would do in C: (*range_ptr).location = 1; Which isn't what you want. I don't know why range.location=1 was working in earlier versions of MacRuby. It should really be a Pointer object. Laurent On May 22, 2010, at 9:50 PM, Robert Rice wrote:
I'm have some trouble understanding the new Pointer class. In older versions of MacRuby I used:
def knowsPageRange( range ) # Override pagination. Image my clip on some printers # The range is passed by reference. range.location = 1 # first page number range.length = 1 true end
MacRuby 0.6 gives me undefined method location= for the Pointer class. Adding an index eliminates the error but then my printing doesn't stop at one page:
def knowsPageRange( range ) # Override pagination. Image my clip on some printers # The range is passed by reference. range[0].location = 1 # first page number range[0].length = 1 true end
How can I fix this? Thanks, Bob Rice
