API implementation or DrawReversibleFrame and FillReversibleRectangle

[joyinfo]

I need to use the API of DrawReversibleFrame and FillReversibleRectangle, but they are not implemented neither in XplatUICocoa.cs nor in XplatUICarbon.cs.

		internal override void DrawReversibleLine(Point start, Point end, Color backColor) {
//			throw new NotImplementedException();
		}

		internal override void FillReversibleRectangle (Rectangle rectangle, Color backColor) {
//			throw new NotImplementedException();
		}

		internal override void DrawReversibleFrame (Rectangle rectangle, Color backColor, FrameStyle style) {
//			throw new NotImplementedException();
		}

Can you give me some thought on how to implement them in Cocoa?

Thanks

They are not implemented because they are used for direct drawing on screen which is not supported on macOS. There is no easy way around it. For controls like splitters we usually create temporary half-transparent windows with a pattern drawn on them to simulate similar effect.
