SelectionMode 枚举为节点选择行为提供了两种选项：

¥The SelectionMode enum provides two options for node selection behavior:

• Full：仅当选择矩形完全包含节点时，才会选中该节点。

  ¥Full: A node is only selected when the selection rectangle fully contains it

• Partial：当选择矩形与节点部分重叠时，才会选中该节点。

  ¥Partial: A node is selected when the selection rectangle partially overlaps with it

enum SelectionMode {
  Partial = 'partial',
  Full = 'full',
}
