CKStackLayoutComponent Class Reference

Inherits from CKComponent : NSObject
Declared in CKStackLayoutComponent.h

Overview

A simple layout component that stacks a list of children vertically or horizontally.

  • All children are initially laid out with the an infinite available size in the stacking direction.
  • In the other direction, this component’s constraint is passed.
  • The children’s sizes are summed in the stacking direction.
    • If this sum is less than this component’s minimum size in stacking direction, children with flexGrow are flexed.
    • If it is greater than this component’s maximum size in the stacking direction, children with flexShrink are flexed.
    • If, even after flexing, the sum is still greater than this component’s maximum size in the stacking direction, justifyContent determines how children are laid out.

For example: - Suppose stacking direction is Vertical, min-width=100, max-width=300, min-height=200, max-height=500. - All children are laid out with min-width=100, max-width=300, min-height=0, max-height=INFINITY. - If the sum of the childrens' heights is less than 200, components with flexGrow are flexed larger. - If the sum of the childrens' heights is greater than 500, components with flexShrink are flexed smaller. Each component is shrunk by ((sum of heights) - 500)/(number of components). - If the sum of the childrens' heights is greater than 500 even after flexShrink-able components are flexed, justifyContent determines how children are laid out.
