elm_list needs elm_list_go() after changing its items, or it won't update anything. > ext_eo = edje_object_part_external_object_get (eo, "Progressbar01"); > elm_progressbar_label_set (ext_eo, "This is the status"); > elm_progressbar_value_set (ext_eo, 0.5); > > Edje_External_Param param; > param.type = EDJE_EXTERNAL_PARAM_TYPE_DOUBLE; > param.name = "value"; > param.d = 5; > edje_object_part_external_param_set (eo, "Slider01", ¶m); > > Edje_External_Param param2; > param2.type = EDJE_EXTERNAL_PARAM_TYPE_STRING; > param2.name = "label"; > param2.s = "Changed Slider Value"; > edje_object_part_external_param_set (eo, "Slider01", ¶m2); > > It works to change the simple widgets (buttons, slider, progressbar) > with both, the API and the params.

EXTERNAL parts are the same, except they create the widget using the externals framework. After that, Edje handles its geometry and visibility, so you should not touch that. In genernal, you never mess with any property from anything created in Edje, but externals are special in that they may have a ton of things they can do, of which Edje knows nothing. So, for that, you must get the object with that function and play with it as if you had created, but always taking into consideration the restrictions mentioned above. With that said, call that function on a non EXTERNAL part, and you should get NULL from it. How that works for you on the C++ bindings I don't know. > Regards > Andreas > > ------------------------------------------------------------------------------ > Beautiful is writing same markup.
