Menu (lv_menu)

Overview

The menu widget can be used to easily create multi-level menus. It handles the traversal between pages automatically.

Parts and Styles

The menu widget is built from the following objects:

  • Main container: lv_menu_main_cont
    • Main header: lv_menu_main_header_cont
    • Main page: lv_menu_page
  • Sidebar container: lv_menu_sidebar_cont
    • Sidebar header: lv_menu_sidebar_header_cont
    • Sidebar page: lv_menu_page

Usage

Create a menu

lv_menu_create(parent) creates a new empty menu.

Header mode

The following header modes exist:

  • LV_MENU_HEADER_TOP_FIXED Header is positioned at the top.
  • LV_MENU_HEADER_TOP_UNFIXED Header is positioned at the top and can be scrolled out of view.
  • LV_MENU_HEADER_BOTTOM_FIXED Header is positioned at the bottom.

You can set header modes with lv_menu_set_mode_header(menu, LV_MENU_HEADER...).

Root back button mode

The following root back button modes exist:

  • LV_MENU_ROOT_BACK_BTN_DISABLED
  • LV_MENU_ROOT_BACK_BTN_ENABLED

You can set root back button modes with lv_menu_set_mode_root_back_btn(menu, LV_MENU_ROOT_BACK_BTN...).

Create a menu page

lv_menu_page_create(menu, title) creates a new empty menu page. You can add any widgets to the page.

Set a menu page in the main area

Once a menu page has been created, you can set it to the main area with lv_menu_set_page(menu, page). NULL to clear main and clear menu history.

Set a menu page in the sidebar

Once a menu page has been created, you can set it to the sidebar with lv_menu_set_sidebar_page(menu, page). NULL to clear sidebar.

Linking between menu pages

For instance, you have created a btn obj in the main page. When you click the btn obj, you want it to open up a new page, use lv_menu_set_load_page_event(menu, obj, new page).

Create a menu container, section, separator

The following objects can be created so that it is easier to style the menu:

lv_menu_cont_create(parent page) creates a new empty container.

lv_menu_section_create(parent page) creates a new empty section.

lv_menu_separator_create(parent page) creates a separator.

Events

  • LV_EVENT_VALUE_CHANGED Sent when a page is shown.
    • lv_menu_get_cur_main_page(menu) returns a pointer to menu page that is currently displayed in main.
    • lv_menu_get_cur_sidebar_page(menu) returns a pointer to menu page that is currently displayed in sidebar.
  • LV_EVENT_CLICKED Sent when a back btn in a header from either main or sidebar is clicked. LV_OBJ_FLAG_EVENT_BUBBLE is enabled on the buttons so you can add events to the menu itself.
    • lv_menu_back_btn_is_root(menu, btn) to check if btn is root back btn

See the events of the Base object too.
