As the method impl suggests, the left value is preferred if all the values are the same. This is the case for the given layout. ```cpp int QLayout::margin() const { int left, top, right, bottom; getContentsMargins(&left, &top, &right, &bottom); if (left == top && top == right && right == bottom) { return left; } else { return -1; } } ```
