Syntax

from Gestures.hpp:115

bool registerDragEvent(uint16_t oldX, uint16_t oldY, uint16_t newX, uint16_t newY);

Arguments

oldX

The x coordinate of the drag start position (dragged from)

oldY

The y coordinate of the drag start position (dragged from)

newX

The x coordinate of the new position (dragged to)
