handleControlPointerDown method

void handleControlPointerDown(
  1. PointerDownEvent event
)

Marks a pointer-down event as belonging to an interactive control inside the custom cell.

Use this when building custom controls manually. This lets the grid select and update the owning row/cell without running the generic cell tap path or moving the horizontal/vertical viewport.

Implementation

void handleControlPointerDown(PointerDownEvent event) {
  onControlPointerDown?.call(event.position);
}
