inBounds method

bool inBounds(MouseMsg msg)

Returns true if the mouse event was in the bounds of this zone's coordinates.

If the zone is not known (isZero), returns false. It calculates this using a box between the start and end coordinates. If you're looking to check for abnormal shapes (e.g. something that might wrap a line, but can't be determined using a box), you'll need to implement this yourself.

Example

case MouseMsg(:final action, :final button) when action == MouseAction.press:
  if (zone.get('my-button')?.inBounds(msg) ?? false) {
    // Button was clicked!
  }

Implementation

bool inBounds(MouseMsg msg) {
  if (isZero) return false;
  if (startX > endX || startY > endY) return false;
  if (msg.x < startX || msg.y < startY) return false;
  if (msg.x > endX || msg.y > endY) return false;
  return true;
}
