Two finger tap gesture unresponsive about avnc

No worries! you are not beholden to my needs, you got a whole ass life to live

Yeah gestures are tricky and they all tend to affect each other - I've developed a multitouch library for Godot that has had to deal with similar issues when I was trying to make my own VNC application 😅 It's super challenging to start, let alone adding support for additional gestures after the fact. Maybe my repo-in-progress could provide some insights, though I doubt it is in any way comparable to what you have going on here. Where do you keep your code for gesture detection?

All incoming touch events are processed in TouchHandler, and gesture detection is here.

Hi @domportera , thanks for taking the time to record the issue.

The root cause for this behavior is that AVNC is trying to differentiate between two-finger-tap and two-finger-pinch gestures. If the fingers move more than a certain threshold after touching the screen, it will be treated as the start of pinch/scroll gesture, and two-finger-tap detection will be cancelled.

I know this is not perfect, but two-finger-tap was a relatively newer addition, I tried to not affect other gestures. I am still looking to improve this situation.

PS: sorry for late response.

Your library is doing all event processing and gesture detection itself, but AVNC builds on top of GestureDetector.

I see, so yeah the logic most certainly wouldn't be transferable in any significant way. I'm hella busy lately but I'll see if I can take a look one day
