Layout.Layer (Google Web Toolkit Javadoc)

java.lang.Object
- com.google.gwt.layout.client.Layout.Layer

Enclosing class:

Layout
```
public class Layout.Layer
extends java.lang.Object
```
This class is used to set the position and size of child elements.
Each child element has three values associated with each axis: {left, right, width} on the horizontal axis, and {top, bottom, height} on the vertical axis. Precisely two of three values may be set at a time, or the system will be over- or under-contrained. For this reason, the following methods are provided for setting these values:
By default, each layer is set to fill the entire parent (i.e., {left, top, right, bottom} = {0, 0, 0, 0}).
