{{uixmltype}}
[[XML/Dimension|Dimension]] is a type used for a variety of purposes for defining values that relate to the UI coordinate system, and is a fundamental UI building block for defining positional layout. See [[XML/Value|Value]] for single value use type. The Dimension type can be used for '''Size''', '''Position''' and others, and can be found on [[XML/LayoutFrame|LayoutFrame]], [[XML/Anchor|Anchor]], and others.
== Inheritance ==
Inherited by: none, Inherits: none, Defined in: multiple
== Elements ==
* <[[XML/AbsDimension|AbsDimension]]> - defines a relative or absolute value, using 'absolute' unit based coordinates
* <[[XML/RelDimension|RelDimension]]> - defines a relative or absolute value, using 'relative' scalar coordinates
== Attributes ==
* x (int) - defines a value thats horizontally opposed
* y (int) - defines a value thats vertically opposed
== Summary ==
[[XML/Dimension|Dimension]] based elements facilitate the 'Layout' mechanism in the WoW UI. When used for <'''Size'''>, along with the <[[XML/Anchors|Anchors]]> element, allow WoW to position all of its visible and interactive elements on the screen, including the 3D views of the world. Dimension works by providing a flexible set of size or positional constructs, by using one of: inline values (X and Y), the [[XML/AbsDimension|AbsDimension]] element, or the [[XML/RelDimension|RelDimension]] element.
=== Example ===
<Frame name="MyFrame">
<Size>
<[[XML/RelDimension|RelDimension]] x="0.5" y="0.5"/>
</Size>
<Frames>
<Frame name="$parentChild">
<[[XML/Dimension|Size]] x="200" y="100"/>
<Anchors>
<Anchor point="TOP">
<Offset>
<[[XML/AbsDimension|AbsDimension]] x="0" y="-22" />
</Offset>
</Anchor>
</Anchors>
</frame>
</Frames>
</Frame>
This example will align the top of the 'child' frame to the top of 'MyFrame', and then offset that alignment by -22 vertically. Also demonstrates use of Dimension with '''Size''' and [[XML/Anchor|Anchor]], and using '''Abs''', '''Rel''' and '''inline''' values.
