Inheritance

• Object

Constructors

GridLayout.new({List<SNumber> begin = const [SNumber.number(0), SNumber.number(0)], bool condense = false, bool preventOverlap = false, num nodeSize = 20, int? rows = 0, int? cols = 0, Fun1<GraphNode, num>? nodeSpaceFun, Fun1<GraphNode, Size>? sizeFun, Fun2<Graph, List<GraphNode>, Map<GraphNode, num>>? sort, bool workerThread = false})

Properties

begin ↔ List<SNumber>

cols ↔ int?

getter/setter pair

condense ↔ bool

为true时最小化画布空间否则最大

hashCode → int

The hash code for this object.

no setter, inherited

nodeSize ↔ num

getter/setter pair

nodeSpaceFun ↔ Fun1<GraphNode, num>?

getter/setter pair

positionFun ↔ Fun3<GraphNode, int, int, Point<int>?>?

位置函数(可用于固定位置)

getter/setter pair
