public abstract class Panel
extends WebMarkupContainer

A panel is a reusable component that holds markup and other components.

Whereas WebMarkupContainer is an inline container like

  ...
  <span wicket:id="xxx">
    <span wicket:id="mylabel">My label</span>
    ....
  </span>
  ...
 

a Panel has its own associated markup file and the container content is taken from that file, like:

  <span wicket:id="mypanel"/>
 
  TestPanel.html
  <wicket:panel>
    <span wicket:id="mylabel">My label</span>
    ....
  </wicket:panel>

Method Detail

newMarkupSourcingStrategy

protected IMarkupSourcingStrategy newMarkupSourcingStrategy()

If Component.getMarkupSourcingStrategy() returns null, this method will be called. By default it returns null, which means that a default markup strategy will be attached to the component.

Please note that markup source strategies are not persisted. Instead they get re-created by calling this method again. That's ok since markup sourcing strategies usually do not maintain a state.

Overrides:

newMarkupSourcingStrategy in class Component

Returns:

Markup sourcing strategy
