dir
The direction along which the items are stacked. Possible values are:
ltr: Left to right.rtl: Right to left.ttb: Top to bottom.btt: Bottom to top.
You can use the start and end methods to obtain the initial and
final points (respectively) of a direction, as alignment. You can also
use the axis method to determine whether a direction is
"horizontal" or "vertical". The inv method returns a
direction's inverse direction.
For example, ttb.start() is top, ttb.end() is bottom,
ttb.axis() is "vertical" and ttb.inv() is equal to btt.
默认:ttb
spacing
Spacing to insert between items where no explicit spacing was provided.
默认:none
children
The children to stack along the axis.
