Hi, With the recent closing of ticket #1002 I have been trying to take a bunch of Objective-C code and write it in MacRuby. One problem that I have run into is with the AXValueGetValue() function in AXValue.h. The last argument to the function is supposed to be the address of a structure to populate; a fragment of that code would look like this: AXValueRef value = (AXValueRef)[self valueOfAttribute:attribute]; CGPoint point; AXValueGetValue( value, kAXValueCGPointType, &point ); return point; If I wanted to write this in MacRuby I think I would have to do something like this: value = valueOfAttribute attribute point = CGPoint.new AXValueGetValue( value, KAXValueCGPointType, point.address_of ) point Except that I have not come across a way to get the address of an object in MacRuby. I have tried the #object_id but then I get errors about the function wanting a Pointer. Is there a way to get a pointer to a specific object or a way to get the address of an object? Thanks, Mark
