Any way to listen for input for a watch face?

Talkabout
over 7 years ago
Hi,

it seems there is no way to handle any input on a watch face. I tried to pass a BehaviorDelegate object as second array element in the "getInitialView" method but then I get the following error in the console:

Unexpected Type Error

I guess this is because input handling for watch faces is not allowed, am I right? If so, the question is why? at least listening to the "back" button makes completely sense, as there is no functionality bound to it when on the watch face. I would like to use this button to toggle information on the watch face itself.

Is there a way to achieve that?

Thanks!

    No way to get input. Watchfaces can't receive input of any type - buttons, taps, swipes, etc. Watchfaces can't do a number of things like vibrate, play tones, etc. And without a background process, no comm, direct sensor access, etc. No timer except after onExitSleep() and before onEnterSleep(), etc.

    That is what I was thinking, thanks for the confirmation :)

    The API doc notes what app types things are supported with.

    Many years later and things have changed. This now works. You can pass it as an argument. E.g.

    function getInitialView() as Array<Views or InputDelegates> ? {
            complicationFaceView = new ComplicationFaceView();
            return [complicationFaceView, new WatchDelegate()] as Array <Views or InputDelegates>;
        }
    class WatchDelegate extends Ui.WatchFaceDelegate {
      function initialize() {
        WatchFaceDelegate.initialize();
      }

      public function onPress(clickEvent) {
        // grab the [x,y] position of the clickEvent
        var co_ords = clickEvent.getCoordinates();
        Sys.println( "clickEvent x:" + co_ords[0] + ", y:" + co_ords[1]  );

        var heartRateComplicationId = new Id(Complications.COMPLICATION_TYPE_HEART_RATE);
        Complications.exitTo(heartRateComplicationId);
        return true;    
      }
    }

    onPress is for complications and devices that support them.  A watch face delegate accepts no other input.  A watch face delegate can see 

    onPowerBudgetExceeded() if you spend too much time in onPartialUpdate().  It's been that way since onPartialUpdate() was introduced.

    See the documentation: Toybox.WatchUi.WatchFaceDelegate (garmin.com)

    I've implemented it and it works in the simulator.

    "Sine API Level 4.2.0".

    So only touch devices with complications
