onTap Override

I've not tried this with an Edge, but in the delegate where you have onTap(). have you tried returning false if you don't handle it but want the system to?  Check the setting in onTap and decide what to do.

It works for Edge. Just add something like

if ($.onTapDisabled) {return false;}

and allow onTapDisabled being set by the user. 

More over, I usually enable onTap for partial areas on the screen (buttons, area around some text or figure, etc) In case that the user do not tap over this area, I return false to allow the system respond to this event and keep both funtionalities

Yes, based on where the tap occurred, you could do "X" if was on the right side of the DF, "Y" if on the left side, and the native behavior if in the middle.  No need for a setting with something like that.

That doesn't work on my CIQ 5 EDGE 1050. Even looking at just a small region prevents tapping from triggering the native function anywhere.

Are you returning true/false depending on where onTap happens

I'll try that! Thanks. I assumed once the delegate is set, that it overrode the tap function regardless. I'll let you know.

How are you defining a region?  With onTap, you can see where the tap occurred, and then consider it valid if it's say +/-50 in width and height from what you expect, and return false if it's not.

I've done this many times with onTap on watches.

I had set touchX and touchY to only consider a specific small region, but that disabled native tap for the whole screen, so I made it work everywhere. But I always return TRUE. Hmm. That was my issue. THANKS!!

Use this structure and return false when user taps out of active area
