MenuListItem

A menu item with a list of (string) values, from which one can be selected using the left/right arrow keys. You can also select a menu list item by pressing enter, which will trigger a separate event that you can listen for.

Example usage

// A list (of strings) containing all selectable values.
// Note: At least one value must be provided.
List<string> values = new List<string>() {
    "Option 1",
    "Option 2",
    "Option 3"
};

// Specify the index which will be used when the item is visible by default.
// Value must be a valid index value for the given values list.
int currentIndex = 0; // ("Option 1")

MenuListItem item = new MenuListItem("Item Text", values, currentIndex, "Item description");

// Add a menu item to a menu:
menu.AddMenuItem(item);

Reacting to a list item

List items raise two different events: one when the value changes, and one when the item is pressed.

MenuListItem timeOfDay = new MenuListItem("Time", new List<string>() { "Morning", "Noon", "Night" }, 0, "Pick a time of day.");
menu.AddMenuItem(timeOfDay);

// Fires every time the user presses left or right on the item.
menu.OnListIndexChange += (_menu, _listItem, _oldIndex, _newIndex, _itemIndex) =>
{
    if (_listItem == timeOfDay)
    {
        Debug.WriteLine($"Preview: {_listItem.ListItems[_newIndex]}");
    }
};

// Fires when the user presses select on the item.
menu.OnListItemSelect += (_menu, _listItem, _listIndex, _itemIndex) =>
{
    if (_listItem == timeOfDay)
    {
        ApplyTimeOfDay(_listItem.GetCurrentSelection());
    }
};

Changing the values later

ListItems is a normal List<string>, so you can change it at any time. Remember to keep ListIndex in range when you do.

item.ListItems = newValues;
item.ListIndex = 0;
