Description

slider: fix value error from step

Summary:
When the slider moves using step,
_drag_value_fetch(), _val_fetch() calculates a value from position of edje_part.
Then the calculated value is updated.
However, this causes a slight error.

This patch updates value ​​first when moving with steps.

  • Test Example
Evas_Object *sl = elm_slider_add(bx);
elm_slider_min_max_set(sl, -5, 5);
elm_slider_value_set(sl, 0.0);
elm_slider_step_set(sl, 0.1);
evas_object_size_hint_align_set(sl, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_size_hint_weight_set(sl, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_smart_callback_add(sl, "changed", _change_cb, NULL);
void
_change_cb(void *data, Evas_Object *obj, void *event_info EINA_UNUSED)
{
   double val = elm_slider_value_get(obj);

   if (val == -5.0) printf("val[%f] == -5.0 \n", val);
   if (val == -4.0) printf("val[%f] == -4.0 \n", val);
   if (val == -3.0) printf("val[%f] == -3.0 \n", val);
   if (val == -2.0) printf("val[%f] == -2.0 \n", val);
   if (val == -1.0) printf("val[%f] == -1.0 \n", val);
   if (val == 0.0) printf("val[%f] == 0.0 \n", val);
   if (val == 1.0) printf("val[%f] == 1.0 \n", val);
   if (val == 2.0) printf("val[%f] == 2.0 \n", val);
   if (val == 3.0) printf("val[%f] == 3.0 \n", val);
   if (val == 4.0) printf("val[%f] == 4.0 \n", val);
   if (val == 5.0) printf("val[%f] == 5.0 \n", val);
}

If you move the slider using step in this test,
You can see that some logs are not visible. (Some values ​​are incorrect)

Test Plan:
elementary_test -to slider
elementary_test -to efl.ui.slider
