menu2 get the id from the label - how to setFocus()

Lee. over 4 years ago

Hi All,

How can I in a Menu2 find the ID of a menuitem by using the label?

I create a menu based on the result of an array of dates (some past, today some future).

I want to setfocus() for the menuID with today's date set as the label (it can vary position given a range of dates.

for(var i =0; i < dateArray; i++){

Menu2.addItem(new WatchUi.MenuItem(Label, subLabel, 1, null));

}

TLDR:

I want to find the ID assigned to a MenuItem given a specific Label

My approach is in the loop that adds the menu item, to check the menu item value against my control value and setFocus() on a hit.

ok, great I've done that but it's not working as expected, perhaps I have misunderstood the function of setfocus.

I assumed if I output the menu via a loop set the ID for my "focused" label to be say 10

the Menu2.setFocus(10);

I expected that when I opened the menu the ID 10 would be the one "highlighted (focused) but it's still starting the menulist at label1 (I hope this makes sense)

when opening the menu I thought setfocus(10) would set my list accordingly?

label1 id=1

LABEL2 id=10

label3 id=2

label4 id=3

I agree: setFocus assumes we all know what that means, but it's not made clear.

What I have found is that Items will be in the same sequence as they were added to the menu, but the list of items will be scrolled up, presenting the "focussed" item will be present at the top of the screen.

yes, that's what I assumed but its not working in the sim

focus is being set on the correct mIdentifier

but the menu on the watch is still "focussing" on the first id

Does anyone know if this is a bug or something I'm doing?

In your variable list, mFocus value is 10, but mItems only has 4 elements, so it's probably confused!

You are incorrectly associating mFocus with mIdentifier (10), it should be the element number ([1]).

I'm not sure why (or how) you are setting the id different to the element number.

Here's one that works:

My snippet was from only a few loops of the loop but you're correct in saying "You are incorrectly associating mFocus with mIdentifier (10), it should be the element number ([1])."

My misunderstanding

Thanks
