elm_progressbar: show status when unit_format_func is set
Summary:
- elm,state,units,visible signal is emitted only when
unit is set, but not when unit_format_func is set.
- Since default unit has been set, this signal is emitted
but signal will not be emitted after unit is set to NULL.
Test Plan:
1. Create a progressbar.
2. elm_progressbar_unit_format_set(obj, NULL);
3. set unit_format_func by elm_progressbar_unit_format_function_set()
and observe elm.text.status part visible.
