class VerticalListFixedRowLayout
package feathers.layout
extends EventDispatcher
implements IVirtualLayout
A simple list layout that positions items from top to bottom, in a single
column, where every item has the same width and height. The items fill the
entire width of the container. The height of items is determined by the
measured height of the first item, or it may be overridden using the
rowHeight property.

.Constructor
Variables
gap:Float
The space, in pixels, between each two adjacent items in the layout.
In the following example, the layout's gap is set to 20 pixels:
layout.gap = 20.0;1.0.0
.paddingBottom:Float
The space, in pixels, between the parent container's bottom edge and its content.
In the following example, the layout's bottom padding is set to 20 pixels:
layout.paddingBottom = 20.0;1.0.0
.paddingLeft:Float
The space, in pixels, between the parent container's left edge and its content.
In the following example, the layout's left padding is set to 20 pixels:
layout.paddingLeft = 20.0;1.0.0
.paddingRight:Float
The space, in pixels, between the parent container's right edge and its content.
In the following example, the layout's right padding is set to 20 pixels:
layout.paddingRight = 20.0;1.0.0
.paddingTop:Float
The space, in pixels, between the parent container's top edge and its content.
In the following example, the layout's top padding is set to 20 pixels:
layout.paddingTop = 20.0;1.0.0
.requestedMaxRowCount:Null<Float>
The maximum number of rows to render, if the height of the container has
not been set explicitly. If null, the maximum number of rows is the
total number of items displayed by the layout.
If requestedRowCount is also set, this property is ignored.
In the following example, the layout's requested maximum row count is set to 5 complete items:
layout.requestedMaxRowCount = 5.0;1.0.0
.requestedMinRowCount:Null<Float>
The minimum number of rows to render, if the height of the container has
not been set explicitly. If null, this property is ignored.
If requestedRowCount is also set, this property is ignored.
In the following example, the layout's requested minimum row count is set to 2 complete items:
layout.requestedMinRowCount = 2.0;1.0.0
.requestedRowCount:Null<Float>
The exact number of rows to render, if the height of the container has
not been set explicitly. If null, falls back to requestedMinRowCount
and requestedMaxRowCount.
In the following example, the layout's requested row count is set to 2 items:
layout.requestedRowCount = 2.0;1.0.0
.rowHeight:Null<Float>
The height to set on each item, or null, if the row height should be
calculated automatically.
In the following example, the layout's row height is set to 20 pixels:
layout.rowHeight = 20.0;1.0.0
.verticalAlign:VerticalAlign
How the content is positioned vertically (along the y-axis) within the container.
Note: The VerticalAlign.JUSTIFY constant is not supported by this
layout.
The following example aligns the container's content to the bottom:
layout.verticalAlign = BOTTOM;1.0.0
