Dynamic menus

Former Member over 8 years ago

Hi,
I would like to develop a dynamic menu, but I don't know how to assign a different identifier to each item in addItem:

var menu = new WatchUi.Menu();
menu.setTitle("MyMenu");
while(content != null)
{
    menu.addItem(content.getName(), :item_dynamic);  
}

If this is not possible, how to know the chosen item in:

function onMenuItem(item) {
        if (item == :item_1)
...

You should have a look at this post. I don't believe anything has changed and there is a lot of good information in there.

Thank you!

One thing to mention here, is in CIQ 3.x, there's a new "Menu2", which makes this a bit simpler, and has options for different things in the menu, like icons, checkboxes, and toggle switches. 3.0.0 is in beta right now, so you can only test with it (no uploads to the store), and Menu2 will only work on devices with a 3.x VM, but depending on your schedule, and the devices you'll be supporting, something to consider.

Thank you! I'm using the Travis solution

Hi Travis,

I'm struggling with this same problem and found your reply here, but the forum does not display any useful content in your reply. It says "You should have a look at this post." but there's no reference to the post. Can you point me in the right direction ?

Thanks

Considering that there's a finite number (16) of items allowed for WatchUi.Menu, you could create 16 symbols which correspond to items 0 to 15 of your menu, then store references to your dynamic items (e.g. numerical/string IDs, or contents) in an array or dictionary. In onMenuItem(), you would call a function or use the dictionary to map the symbol back to the ID or contents of the corresponding dynamic item.

If you want more flexibility (like the ability to change the menu contents after the menu is created), you could use Menu2 (for CIQ 3 devices), or if you also want to support older devices, you write your own view or use a 3rd party menu such as:

github.com/.../Dmenu

(Menu2 allows the item ID to be something other than a symbol, such as a string)

Thanks Travis.

Just wanted to point out that Travis' solution is similar to what I suggested (although maybe I could've explained it better). I wouldn't have minded writing up a code sample if you had been interested.

Thanks.

After more reading on the forum I put together a solution that works and is essentially the same as what you and Travis proposed.

Thanks for your help.
