Attached to the mail is a patch for elm_panes.

I have a query that shall we hide the unset content in the widget itself or should application explicitly hide them after unsetting!
In case of edje_object_part_unswallow, application needs to do it explicitly and it is documented but in case of elm_object_part_content_unset, there is no documentation available.

Details of the patch:

Existing Issue before this change:
   1. Panes deletes the older content while setting a new content even though both are same.
   2. left and right content are being unswallowed in the content_left_set and _content_right_unset functions. So when the reparenting happens, say when the content is put inside a layout then only _sub_del gets called and
unswallowing does not happen as these functions do not get called.
e.g.   @@ -253,8 +250,6 @@ _content_left_unset(Evas_Object *obj)
    if (!wd->contents.left) return NULL;
    Evas_Object *content = wd->contents.left;
    elm_widget_sub_object_del(obj, content); //wd->contents.left already gets set to NULL in _sub_del
-   edje_object_part_unswallow(wd->panes, content); // can be unswallowed in _sub_del as in case of reparenting like setting content in a layout, only _sub_del will get called, not this function
-   wd->contents.left = NULL; //this instruction is redundent as it happens in _sub_del anyway
    return content;
 }
Change Description:
  1. Unswallowing the contents now in _sub_del as this is a common function to be executed when subobject removal happens.
  2. Comparing the current content with new before deleting.
