Watchface - Wanting to add touch for complications

Watchapp/Face Developers Corner

I have added support for my watchface to support touch to tap to swap between complications but it is not working.

I did this as I saw the pebble os now supports touch, but maybe I jumped the gun. Are watch faces supported yet for touch? Or is it still limited to apps and the main menu of pebble OS?

Example:

#if defined(PBL_PLATFORM_EMERY)
static void touch_handler(const TouchEvent *event, void *context) {
if (tap_to_cycle) {
// Cycle to the next metric (Steps → Weather → Heart → Sleep)
active_display_metric = (active_display_metric + 1) % 4;
layer_mark_dirty(weather_layer);
}
}
#endif

Watch faces don’t support touch yet. We’re holding off on this until we figure out how gestures and touch will work for all watch faces, rather than each one coming up with a different gesture scheme.

I see. Thank you very much!

Might I suggest just simply allowing a tap on the watchface to trigger something, vs worrying about gestures and all that? That way it doesn’t get complicated too fast. My flow idea is this, you would tap to wake watch > tap again to switch between complications.

I dont see a problem forcing the buttons to be used on notifications and opening the menu.

But I understand that’s not a high priority right now.

Thanks!

You can actually do that today with an accelerometer shake detector. Many watch faces do this to change the complication.

thats a good point. I find shake to kill battery life faster so I was trying to simply do touch. But this is a good idea as another option. Thanks.
