In my D13 FMX app I’m trying to implement a swipe gesture to clear the screen on a left or right swipe (sgiLeft or sgiRight). It works, but is still triggered even with the smallest swipe, whereas I’d like it to require a good half of the screen. I can’t see a way to adjust it as the distance part of EventInfo (TGestureEventInfo) is not used for most gestures.
I’m not sure if the lack of replies is because others here don’t use gestures or they are happy with the way they work.
TBH I’ve not noticed a problem for me. I am using iOS 26 on an iPhone 15 Pro and Android 16 on a Galaxy S25 Ultra. Not sure if that makes any difference at all.
On my Samsung tablet (S6 Lite IIRC) you only need to swipe a few millimeters to trigger the gesture.
What sort of distance (or percentage of the screen) would be considered normal for these gestures?
I honestly don’t know but for me it’s more than a few mm. 20% of the surface (button, panel, etc) would seem to be fair but I am guessing.
