Well, that kind of sucks... Second question: given an Evas_Object (what is passed into the "clicked" event callback -- I am assuming this is the elm_button object), is it possible to get the *root* x & y position? I know that I can get the object's *relative* [to its parent] x and y via evas_object_geometry_get(), but how would I get the root window position? I presume I would have to walk up the tree, but would this work correctly? static void event_cb(void *data, Evas_Object *obj, void *event_info) { Evas_Coord relx, rely, topx, topy, rootx, rooty, w, h; Evas_Object *top = elm_object_top_widget_get ( obj ); evas_object_geometry_get (obj, &relx, &rely, &w, &h); evas_object_geometry_get (top, &topx, &topy, NULL, NULL); rootx = topx + relx; rooty = topy + rely; ... } Evas_Object *button = elm_button_add(win); evas_object_smart_callback_add(button, "clicked", event_cb, mumble); > > > -- > > Robert Heller -- 978-544-6933 / hel...@deepsoft.com > > Deepwoods Software -- http://www.deepsoft.com/ > > () ascii ribbon campaign -- against html e-mail > > /\ www.asciiribbon.org -- against proprietary attachments > > > > > > > > > > ------------------------------------------------------------------------------ > > WatchGuard Dimension instantly turns raw network data into actionable > > security intelligence.
