This example shows how to create a menu with regular items, object items, submenus and how to delete items from a menu. The full source for this example is menu_example_01.c.
We'll start looking at the menu creation and how to create a very simple item:
For our next item we are going to add an icon:
menu_it =
elm_menu_item_add(menu, NULL,
"mail-reply-all",
"second item", NULL, NULL);
Now we are going to add more items, but these icons are going to have a parent, which will put them in a sub-menu. First just another item with an icon:
Next we are going to add a button to our menu(any elm widget can be added to a menu):
elm_object_text_set(button, "button - delete items");
We are also going to have the button delete the first item of our sub-menu when clicked:
elm_object_item_content_set(menu_it1, button);
evas_object_smart_callback_add(button, "clicked", _del_it, menu);
static void
_del_it(void *data, Evas_Object *obj, void *event_info)
{
const Eina_List *l;
menu_it = elm_menu_item_next_get(menu_it);
l = elm_menu_item_subitems_get(menu_it);
}
We now add a separator and three more regular items:
static void
_show(void *data, Evas *e, Evas_Object *obj, void *event_info)
{
Evas_Event_Mouse_Down *ev = event_info;
evas_object_show(data);
}
EAPI_MAIN int
elm_main(int argc, char **argv)
{
Evas_Object *win, *menu, *button, *rect;
rect = evas_object_rectangle_add(evas_object_evas_get(win));
evas_object_size_hint_min_set(rect, 0, 0);
evas_object_color_set(rect, 0, 0, 0, 0);
evas_object_show(rect);
menu_it =
elm_menu_item_add(menu, NULL,
"mail-reply-all",
"second item", NULL, NULL);
We now add another item, however this time it won't go the sub-menu and it'll be disabled:
elm_object_text_set(button, "button - delete items");
elm_object_item_content_set(menu_it1, button);
evas_object_smart_callback_add(button, "clicked", _del_it, menu);
To make sure that our menu is shown whenever the window is clicked(and where clicked) we use the following callback:
static void
_del_it(void *data, Evas_Object *obj, void *event_info)
{
const Eina_List *l;
menu_it = elm_menu_item_next_get(menu_it);
l = elm_menu_item_subitems_get(menu_it);
}
Our example will look like this:
