ItemSubMenu

Constructor

ItemSubMenu(const char* text, MenuItem** parent);

This constructor creates a new ItemSubMenu object with the specified parameters.

Parameters

• text: The text to display for the sub-menu item.

• parent: A pointer to the parent menu item that will contain the sub-menu.

The ItemSubMenu class inherits from the ItemHeader class and sets the MENU_ITEM_SUB_MENU type for the menu item. The text parameter specifies the text that will be displayed for the sub-menu item. The parent parameter is a pointer to the parent menu item, which will contain the sub-menu item.

Please note that the parent parameter is of type MenuItem**, indicating a pointer to a pointer to a MenuItem object.

ITEM_SUBMENU

#define ITEM_SUBMENU(...) (new ItemSubMenu(__VA_ARGS__))

The ITEM_SUBMENU macro creates a new ItemSubMenu object using the provided arguments and returns a pointer to it.

Usage

The ITEM_SUBMENU macro can be used to conveniently create instances of the ItemSubMenu class without explicitly calling the constructor. It simplifies the process of creating sub-menu items by providing a compact syntax.

Arguments

The ITEM_SUBMENU macro takes the following arguments:

• ...: Variable number of arguments that are passed to the ItemSubMenu constructor. These arguments should match the parameters of the ItemSubMenu constructor in the correct order.

By using the ITEM_SUBMENU macro, you can create instances of the ItemSubMenu class as follows:

ITEM_SUBMENU("Sub Menu", &parentMenu)

In this example, "Sub Menu" is the text to display for the sub menu item, and &parentMenu is the pointer to the parent menu item.

Please note that the ITEM_SUBMENU macro expands to a dynamically allocated ItemSubMenu object, so you need to manage memory accordingly to prevent memory leaks.
