Instance Method Details

#to_ax ⇒ AXValueRef

Create an AXValueRef from the Boxed instance. This will only work if for the most common boxed types, you will need to check the AXAPI documentation for an up to date list.

Examples:


CGPoint.new(12, 34).to_ax # => #<AXValueRef:0x455678e2>
CGSize.new(56, 78).to_ax  # => #<AXValueRef:0x555678e2>

Returns:

  • (AXValueRef)
