All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, HtmlBasedComponent, Component, Scope, ComponentCtrl, Div, XulElement

public class Div
extends XulElement
implements Div

The same as HTML DIV tag.

An extension. It has the same effect as <h:div xmlns:h="http://www.w3.org/1999/xhtml">. Note: a Window without title and caption has the same visual effect as Div, but Div doesn't implement IdSpace. In other words, Div won't affect the uniqueness of identifiers.

getOuterAttrs

public java.lang.String getOuterAttrs()

Description copied from class: HtmlBasedComponent

Returns the exterior attributes for generating the enclosing HTML tag; never return null.

Used only by component developers.

Default: Generates the tooltip text, style, sclass, draggable and droppable attribute if necessary. In other words, the corresponding attribute is generated if HtmlBasedComponent.getTooltiptext(), HtmlBasedComponent.getRealStyle(), HtmlBasedComponent.getSclass(), HtmlBasedComponent.getDraggable(), HtmlBasedComponent.getDroppable() are defined.

You have to call both HtmlBasedComponent.getOuterAttrs() and HtmlBasedComponent.getInnerAttrs() to generate complete attributes.

For simple components that all attributes are put on the outest HTML element, all you need is as follows.

<xx id="${self.uuid}"${self.outerAttrs}${self.innerAttrs}>

If you want to put attributes in a nested HTML element, you shall use the following pattern. Notice: if HtmlBasedComponent.getInnerAttrs() in a different tag, the tag must be named with "${self.uuid}!real".

<xx id="${self.uuid}"${self.outerAttrs}>
 <yy id="${self.uuid}!real"${self.innerAttrs}>...

Note: This class handles non-deferrable event listeners automatically. However, you have to invoke AbstractComponent.appendAsapAttr(java.lang.StringBuffer, java.lang.String) for each event the component handles in HtmlBasedComponent.getOuterAttrs() as follows.

        appendAsapAttr(sb, Events.ON_OPEN);
  appendAsapAttr(sb, Events.ON_CHANGE);

Theorectically, you could put any attributes in either HtmlBasedComponent.getInnerAttrs() or HtmlBasedComponent.getOuterAttrs(). However, zkau.js assumes all attributes are put at the outer one. If you want something different, you have to provide your own setAttr (refer to how checkbox is implemented).

Overrides:

getOuterAttrs in class XulElement
