I didn't display a dialog box, but a popup menu. I used it for drag&drop of a custom extension file. It was very convenient to prompt the user what to do with the dropped file. Anyway, I moved that logic to a messagedata plugin that gets called from the sceneloader and that way I can show the popup menu :)
