Hi, currently KFilePlaceEditDialog is not exported by kfilewidgets. As I understand it, it's supposed to be used only through KFilePlacesView (that's what gwenview and konqueror do).
However, Dolphin is using its own implementation of KFilePlacesModel/KFilePlacesView. This is why Dolphin has its own dialog to edit places, which is exactly the same as KFilePlaceEditDialog but with more bugs, e.g. see [1]. Could we make KFilePlaceEditDialog a public class? I don't really see downsides in doing this. We reduce code duplication (by killing the buggy Dolphin dialog) and Dolphin can still use its own model/view places stuff (I tested it localy and seems to work).
