Hi Mark, I think the following would work: value = valueOfAttribute attribute point_ptr = Pointer.new(CGPoint.type) AXValueGetValue( value, KAXValueCGPointType, point_ptr ) point = point_ptr[0] Basically, you want to pass a pointer to a CGPoint to the API.

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
