SUI.AnchorLayout

SUI.AnchorLayout is the the component that handles the layout of anchored boxes. Anchoring means that child boxes can be positioned relative to the edges of the anchor layout box.

Suppose you have an input field with a label. In this situation the label has a fixed size and if the form is enlarged and you only want the input field to resize.

This is easy to accomplish with an anchor layout. The label will have a fixed width and will be anchored to the left side of the container box (an instance of SUI.AnchorLayout). The input field will be anchored on the left and right of the container box, setting the left to a value slightly larger that the right side of the label and the right to zero. When resizing the container the label will always be shown at its fixed width and the rest of the width will be used for the input field.

Or in code:

var b = new SUI.AnchorLayout({ top: 10, left 10, width: 800, height: 800 can contain other box elements. It is essentially nothing more than a SUI.Box with a list of children. It knows how to deal with anchored boxes.
