VerticalDistributedLayout class may be used to position the children of a container from top to bottom, in a single column — where the total height of the container is distributed equally to the heights of each child. In other words, each child will have the same height, and their sum is equal to the total height of the container.
This layout is designed to be used with basic containers like
ScrollContainer, which are intended purely for visual layout and do not offer built-in capabilities for rendering data from a collection. If using a container that renders a collection of data — such as
GridView— consider using other layouts that are optimized for data containers by offering performance improvements like layout virtualization.
var container = new LayoutGroup(); addChild(container); var child1 = new Button(); child1.text = "One"; container.addChild(child1); var child2 = new Button(); child2.text = "Two"; container.addChild(child2); var child3 = new Button(); child3.text = "Three"; container.addChild(child3);
container.layout = new VerticalDistributedLayout();
By default, the first child will be positioned in the top-left corner. Each additional child will be positioned below the previous child — creating a single, vertical column.
The following sections will introduce a number of properties that may be used to adjust the positioning and sizing of children in the layout.
layout.paddingTop = 10.0; layout.paddingRight = 15.0; layout.paddingBottom = 10.0; layout.paddingLeft = 15.0;
If all four padding properties should be set to the same value, call the
setPadding() method instead.
// sets top, right, bottom and left to the same value layout.setPadding(10.0);
gap refers to the space, measured in pixels, between each child in the container.
layout.gap = 5.0;
