I have been exploring ways to display 2-D Mathematica graphics objects in GUIKit, and convert mouse click coordinates into Mathematica graphics coordinates. I have a mechanism, which is incorporated in my SuperWidgetPackage. This works well for me, but not for some others - so there are obviously still some issues to be ironed out. Please look at my website for more details, and maybe contact me directly. David Bailey dbaileyconsultancy.co.uk
