LayoutNode class abstract

Constructors

LayoutNode()

Properties

baselineFunction ↔ BaselineFunction?

Provide a function for measuring the baseline (in Y) of the contents of the node. The layout engine uses this when the alignment is set to baseline. Only works on leaf nodes (nodes with no further child layout nodes).

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

layout → Layout

no setter

measureFunction ↔ MeasureFunction?

Provide a function for measuring the desired dimensions of the LayoutNode. This lets the layout engine know the intrinsic size of the contents. This doesn't guarantee the final size of the node will match but lets the layout attempt to provide the desired size when possible. Only works on leaf nodes (nodes with no further child layout nodes).
