Class Border

Direct Known Subclasses:

public abstract class Border
extends WebMarkupContainerWithAssociatedMarkup
implements IComponentResolver

A border component has associated markup which is drawn and determines placement of any markup and/or components nested within the border component.

The portion of the border's associated markup file which is to be used in rendering the border is denoted by a <wicket:border> tag. The children of the border component instance are then inserted into this markup, replacing the first <wicket:body> tag in the border's associated markup.

For example, if a border's associated markup looked like this: 

              <html>
              <body>
                <wicket:border>
                    First <wicket:body/> Last
                </wicket:border>
              </body>
              </html>
And the border was used on a page like this: 
              <html>
              <body>
                <span wicket:id = "myBorder">
                    Middle
                </span>
              </body>
              </html>
Then the resulting HTML would look like this: 
              <html>
              <body>
                    First Middle Last
              </body>
              </html>
In other words, the body of the myBorder component is substituted into the border's associated markup at the position indicated by the <wicket:body> tag.

Regarding <wicket:body/> you have two options. Either use <wicket:body/> (open-close tag) which will automatically be expanded to <wicket:body>body content</wicket:body> or use <wicket:body>preview region</wicket:body> in your border's markup. The preview region (everything in between the open and close tag) will automatically be removed.

Border

public Border(java.lang.String id,
              IModel model)
See Also:
Component.Component(String, IModel)
Method Detail

setBorderBodyVisible

public Border setBorderBodyVisible(boolean bodyVisible)
When this method is called with a false value the components and raw markup that this border wraps will not be rendered.

Parameters:
bodyVisible -
Returns:
this for chaining

isTransparentResolver

public boolean isTransparentResolver()
Description copied from class: MarkupContainer
Some MarkupContainers (e.g. HtmlHeaderContainer, BodyOnLoadContainer) have to be transparent with respect to there child components. A transparent container gets its children from its parent container.

Overrides:
isTransparentResolver in class MarkupContainer
Returns:
false. By default a MarkupContainer is not transparent.
See Also:
MarkupContainer.isTransparentResolver()

setTransparentResolver

public final Border setTransparentResolver(boolean transparentResolver)
Borders used for bordered pages should set it to "true". Default is "false".

Parameters:
transparentResolver -
Returns:
this for chaining

resolve

public final boolean resolve(MarkupContainer container,
                             MarkupStream markupStream,
                             ComponentTag tag)
Border makes use of a <wicket:body> tag to identify the position to insert within the border's body. As <wicket:body> is a special tag and MarkupContainer is not able to handle it, we do that here.

You have two options. Either use <wicket:body/> (open-close tag) which will automatically be expanded to <wicket:body>body content</wicket:body> or use <wicket:body>preview region</wicket:body> in your border's markup. The preview region (everything in between the open and close tag) will automatically be removed.

Specified by:
resolve in interface IComponentResolver
Parameters:
container - The container parsing its markup
markupStream - The current markupStream
tag - The current component tag while parsing the markup
Returns:
True if componentId was handled by the resolver, false otherwise.
See Also:
IComponentResolver.resolve(MarkupContainer, MarkupStream, ComponentTag)

onComponentTagBody

protected final void onComponentTagBody(MarkupStream markupStream,
                                        ComponentTag openTag)
Render the tag body

Overrides:
onComponentTagBody in class MarkupContainer
Parameters:
markupStream - The markup stream
openTag - The open tag for the body
See Also:
Component.onComponentTagBody(wicket.markup.MarkupStream, wicket.markup.ComponentTag)

renderHead

public void renderHead(HtmlHeaderContainer container)
Description copied from class: Component
Print to the web response what ever the component wants to contribute to the head section. Make sure that all attached behaviors are asked as well.

Overrides:
renderHead in class Component
Parameters:
container - The HtmlHeaderContainer
See Also:
Component.renderHead(wicket.markup.html.internal.HtmlHeaderContainer)

renderBodyComponent

public void renderBodyComponent(MarkupStream markupStream,
                                WicketTag wtag)
Render the wicket:body and all what is in it.

Parameters:
markupStream - The associated markup stream
wtag - The wicket:body tag

renderBodyComponentTagBody

public void renderBodyComponentTagBody(MarkupStream markupStream,
