Improvement : InfoField

[fmatray]

Hello,
Is it possible to add an InfoField ?

This field is just to display a title and a value without any edition.
This can be usefull to show some information like "Your IP:192.168.0.13" or "API key: FCUGUOZBDQSB".

For the moment I do something with like this but it's not elegant and generic.

result show_ip() {
  [display on the LCD]
  return proceed;
}
OP("Show IP", show_ip, enterEvent)

INFO(Value, "Title", Menu::doNothing, Menu::noEvent, Menu::noStyle).

yes, you can set a field read only, the field can also be hooked up to a live variable and display ie: an analog read with self/auto update

Do you have an example, please ?

I tried like this:

const char *constMEM empty[] MEMMODE = {};
EDIT("IP:", "192.168.0.1", empty, Menu::doNothing, Menu::noEvent, Menu::noStyle)

The is shown but when I click on this item, I enter in an edition mode without any possibility to change. It's a kind of confusing workaround as the user believes changing the value is possible.

Moreover, an EDITField not editable is a bit confusing :-)

Enable/Disable is a runtime setting, all menu items have it
usage example:

mainMenu[0].disable();
mainMenu[1].enable();

source: https://github.com/neu-rah/ArduinoMenu/blob/master/src/items.h#L47

there is still space for improvement, we don't have a function to check enabled/disabled state,
there is enabled member with status enum with values: {disabledStatus=0,enabledStatus=1};

src: https://github.com/neu-rah/ArduinoMenu/blob/master/src/menuBase.h#L149

but this can be confusing and hard to remember. As enabled name is already used we can have a disabled() function to return a boolean instead of that enum.

ie:

inline bool disabled() const {return enabled==disabledStatus;}

or we can have a set function that accepts a boolean (can also be enable overload)

Thanks a lot. Works fine like this :

const char *constMEM empty[] MEMMODE = {};

MENU(advanced_menu, "Advanced", Menu::doNothing, Menu::noEvent, Menu::noStyle, 
[...]
EDIT("@", wificonnexion.localIP, empty, Menu::doNothing, Menu::noEvent, Menu::noStyle),
[...]
advanced_menu[3].disable();
