Question: Transferring an in progress gesture

[nixterrimus]

Hello!

I'm working on a keypad that has multiples pages, buttons that press, buttons that long press and bring up a popover and popovers that you can pan between options. Wheh! Here's what I've got so far:

I think I need to transfer the long press gesture to the pan gesture so that I can select items in the submenu. Is there any way to do this? Things are kind of working by using simultaneousHandlers on the pan gesture handler but that eats up the paging gesture. What I really want to say to the pan gesture handler- Wait until the long press is fired and then when the finger moves begin to recognize.

Thanks @nixterrimus for reaching out.

I'm not sure I fully understand your usecase but let me try to answer regardless:

So I think what you may want to try is just having the LongPressHandler to implement button along with the submenu. You should be able to use onHandlerStateChange event to determine when long press occurs and show submenu and also have onGestureEvent callback registered to be able to get pointer (finger) position while long press is happening. Also you should set shouldCancelWhenOutside={false} as you don't want longpress handler to cancel when you swipe away from the button while panning over the submenu. Please note that you will be getting raw gesture events (via onGestureEvent callback) only when the state of the handler is ACTIVE.
