Methods (function)

[renejeanmercier]

Hi Mr. Black,

Firstly, thank you for that unique and well thought menu system. The fact that each menu item can call a function to adapt to the user needs and all sorts of displays makes your menu system universally usable.

Jon, in the documentation at https://jonblack.me/arduino-menu-system-library/, you refer to two (2) method : ms.get_num_menu_items(); // get the number of menu items in the current menu and ms.get_cur_menu_item(); // get the current menu item number in the current menu.

These methods are not present in the actual library. Is there a reason ?

Hi Jon,

Thank you for your quick reply to my previous email.

I have 6 main menu items in my application and each sub-menu has a different number of items (see below), but I can only display 3 items at a time on the TFT display due to other information displayed in an other area of the TFT.

Therefore I need to scroll the menu items up and down in a kind of windowing approach : say I have items 1, 2 and 3 displayed. If the focus is already on item 3 and I turn the rotary encoder down one step, I need to display items 2, 3, and 4, an so on and vis-versa.

The get_num_menu_items() and get_cur_menu_item() where perfect for such functionality. Before I undertake to write such functions outside of the "menu system" (in my application) I was wondering if you had replaced these functions with equivalent functions in your actual version. Or you might want to help me (your C++ caliber is in the top professional, mine at the bottom of the barrel ...hold man in the 70 years of age trying to catch-up :-)) in suggesting an approach to follow.

Thank you so much for your help and understanding.

Regards,

I have a similar problem and got another approach to solve it. I have an 16x2 LCD so i can only display 2 lines of the menu. So i display in the first row the parent menu item and in the second row the active menu itemn or value. With the encoder i can rotate thru all menu items, a click just activates the selected item. If it's a menu, it opens it, if it's a value, the value editor starts. In every submenu i have a back menu item, just to go one level higher.
