Class Layout.Layer

java.lang.Object
com.google.gwt.layout.client.Layout.Layer
Enclosing class:
Layout
public class Layout.Layer extends 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}).
