[macos] Multiple Accessibility APIs missing

[chamons]

This code works in ObjC:

    NSPopUpButton *p = [[NSPopUpButton alloc] init];
    p.accessibilityIdentifier = @"hello";
    NSString *result = p.accessibilityIdentifier;

But this does not in C#:

NSPopUpButton button = new NSPopUpButton ();
button.AccessibilityIdentifier = "hello";
var result = button.AccessibilityIdentifier;

It comes off the full set in:

@protocol NSAccessibility <NSObject>
@required

[chamons]

NSButton has NSControl which has NSAccessibility so it should have a get and set, but it doesn’t, might be a generator bug. At first glance the bindings look right.

[spouliot]

@chamons which branch ? Bindings for NSControl does not implement NSAccessibility protocol in stable (15.8 / xcode10.1)

[spouliot]

So things are a bit different than XI.

NSAccessibilityElementProtocol defines as a getter only, while NSAccessibility defines it with a getter and setter. Both are applied to NSView (from which all controls gets this).

[chamons]

Yeah, sorry for the delay, it gets it from NSView:
