OK, I *think* I know what is going on. The table widget does not itself have
a backgroud -- it get that from its 'parent', (eg an elm_win widget or
something). The thing here is that the table does not have an *elm* widget as
a parent. Its 'parent' (such as it is) is a bare Edje Evas_Object. Basically
I am creating a Edje Evas_Object and setting it up as a menu background:
/* Create a window, and realize the menu in it. */
o = edje_object_add(e_comp_get(m->zone)->evas);
evas_object_name_set(o, "start_menu->sw_bg_object");
evas_object_data_set(o, "e_start_menu", m);
e_theme_edje_object_set(o, "base/theme/menus",
"e/widgets/menu/default/background");
m->sw_bg_object = o;
And then using this as the parent object when I create the table:
/* Create the menu container, an Elm Table widget. */
o = elm_table_add(canvas); /* canvas IS m->sw_bg_object */
fprintf(stderr,"*** e_start_menu_realize_inwindow(): elm_table_add(%p)
returns %p\n",canvas,o);
m->container_object = o;
And finally I am using edje_object_part_swallow() to swallow the elm_table
into the background object. I'm guessing this is wrong. I need to do
something different somewhere, but I am unsure what I should be doing.
There isn't any good documentation on what is the proper way to use elm
widgets with Enlightenment itself. The Enlightenment 'widgets' (and even more
primitive e_<thing> things) leave lots to be desired and are poorly documented
and are effectively depreciated -- eventually Enlightenment will move to use
Elementary (elm) widgets, so there must be a proper way to do this. Or at
least there is a contemplated way of doing this. What is it?
