Use updateEvent to trigger a callback in choose or select fields

[waisens]

Hi rui: I am playing with Arduino again. Is it possible to call a callback function when updating a value selected by a "select" or "choose" field?

Menu::select& Modes = new Menu::select("mode", mode, sizeof(Modes_Data) / sizeof(prompt), Modes_Data, (Menu::callback)mode_cb, updateEvent);

With a toggle field it works using "enterEvent".

toggle& Modes = new toggle("mode", mode, sizeof(Modes_Data) / sizeof(prompt), Modes_Data, (Menu::callback)mode_cb, enterEvent);

But with the fields "select" or "choose" I cannot use "enterEvent" and when I use "updateEvent" the function is not called.

Note: "updateEvent" works correctly when I edit numerical values for example

menuField <typeof(deltaVal)> &Delta = *new menuField<typeof(deltaVal)> (deltaVal, "delta", "m", 0.1, 10.0, 1, 0.1, (Menu::callback)deltaVal_cb, updateEvent);

Thank you in advance

yes, this example might help, some events can be handled on the parent element, and there are also focus/blur events.

let it run and watch the printout

just let me know if you need more help

Thank you!!! "exitEvent" works as I expected

Menu::select& Modes = new Menu::select("mode", mode, sizeof(Modes_Data) / sizeof(prompt), Modes_Data, (Menu::callback)mode_cb, exitEvent);

Menu::choose& Modes = new Menu::choose("mode", mode, sizeof(Modes_Data) / sizeof(prompt), Modes_Data, (Menu::callback)mode_cb, exitEvent);
