Hi, I've made a small experiment, dragging a file to Pharo's window, which caused to instantiate a FileList object (shown as a pop-up window) with instance variable reference containing a FileReference object corresponding to the file chosen. (Does this make sense?) The question is, how can I customize this to get this FileReference instance and assign it to some arbitrary class instance variable? In other words, how does the dnd event work in this case? Thanks Christian
