[Rd] graphics device event handling

Hi All

I run across the following situation quite frequently and was wondering if there exists a simple solution that I missed.

I develop some graphical display using the nice basic R graphical functions (plots, lines, images, histogramm ...). Now I would like to add a few simple user interaction capabilities.

There seems to be no simple callback type event handling for mouse/keyboard events for the basic graphics devices. The setGraphicsEventHandlers only work on X11 (on MAC) which doesn't look nearly as nice as the basic quartz device and doesn't support transparency.

Is there a way to add graphics event handling to the CairoX11 or quartz interface in a similar simple fashion as the setGraphicsEventHandlers framework without requiring packages such as Rgtk and deviceCairo which can get fairly large and seem somewhat overkill for adding few simple interactions to existing R plot compositions.

Kind Regards
