class VerticalLayoutData
package feathers.layout
extends EventDispatcher
implements ILayoutData
Provides optional percentage sizing for children of containers that use
VerticalLayout
.
Events:
openfl.events.Event.CHANGE | Dispatched when a property of the layout data changes, which triggers the container to invalidate. |

Static methods
staticfill():VerticalLayoutData
Creates VerticalLayoutData
that fills the parent container, with the
percentWidth
and percentHeight
both set to 100.0
.
In the following example, one of the container's children fills the container's bounds:
var container = new LayoutGroup();
container.layout = new VerticalLayout();
var child = new Label();
child.layoutData = VerticalLayoutData.fill();
container.addChild(child);

.See also:
staticfillHorizontal(percentWidth:Float = 100.0):VerticalLayoutData
Creates VerticalLayoutData
that fills the width of the parent
container, with the ability to optionally specify a percentage value to
pass to percentWidth
.
In the following example, one of the container's children fills the container's width:
var container = new LayoutGroup();
container.layout = new VerticalLayout();
var child = new Label();
child.layoutData = VerticalLayoutData.fillHorizontal();
container.addChild(child);

.See also:
staticfillVertical(percentHeight:Float = 100.0):VerticalLayoutData
Creates VerticalLayoutData
that fills the height of the parent
container, with the ability to optionally specify a percentage value to
pass to percentHeight
.
In the following example, one of the container's children fills the container's height:
var container = new LayoutGroup();
container.layout = new VerticalLayout();
var child = new Label();
child.layoutData = VerticalLayoutData.fillHorizontal();
container.addChild(child);

object from the given arguments.

.Variables
marginBottom:Null<Float>
Extra space, measured in pixels, that is inserted after this item in the layout.
This item's marginBottom
value will be added to the layout's gap
value and the next item's marginTop
value to create the total space
between items. If this is the last item in the layout, nothing will be
added too the marginBottom
value.
Negative values are allowed for the margins.
1.1.0
.See also:
marginTop:Null<Float>
Extra space, measured in pixels, that is inserted before this item in the layout.
This item's marginTop
value will be added to the layout's gap
value and the previous item's marginBottom
value to create the total
space between items. If this is the first item in the layout, nothing
will be added to the marginTop
value.
Negative values are allowed for the margins.
1.1.0
.See also:
percentHeight:Null<Float>
The height of the layout object, as a percentage of the parent container's height.
A percentage may be specified in the range from 0.0
to 100.0
. If the
value is set to null
, this property is ignored and the standard height
in pixels will be used.
The parent container will calculate the sum of all of its children with
explicit pixel heights, and then the remaining space will be distributed
to children with percent heights. Additionally, if the total sum
of percentHeight
values exceeds 100.0
, all percentHeight
values
will be normalized to the range from 0.0
to 100.0
.
In the following example, the height of a container's child is set to 50% of the container's height:
var container = new LayoutGroup();
container.layout = new VerticalLayout();
var percentages = new VerticalLayoutData();
percentages.percentHeight = 50.0;
var child = new Label();
child.layoutData = percentages;
container.addChild(child);
1.0.0
.percentWidth:Null<Float>
The width of the layout object, as a percentage of the parent container's width.
A percentage may be specified in the range from 0.0
to 100.0
. If the
value is set to null
, this property is ignored.
Tip: If all children of the same container will have the percentWidth
value set to 100.0
, it's better for performance to set
VerticalLayout.horizontalAlign
to HorizontalAlign.JUSTIFY
instead.
In the following example, the width of a container's child is set to 50% of the container's width:
var container = new LayoutGroup();
container.layout = new VerticalLayout();
var percentages = new VerticalLayoutData();
percentages.percentWidth = 50.0;
var child = new Label();
child.layoutData = percentages;
container.addChild(child);
