Sure there a dozens of ways todo this, mine is just one of them. Im
starting a new thread since it'll be more exposed then.
The idea is following:
Parent:
public class BasePage extends WebPage {
protected final String LINK_LABEL_ID = "linkText";
protected final String LINK_ID = "link";
protected final String FOOTER_ID = "item";
protected final String HEADER_ID = "item";
protected List<WebMarkupContainer> generalAccordionItem = new
ArrayList<WebMarkupContainer>();
protected List<WebMarkupContainer> footer = new
ArrayList<WebMarkupContainer>();
protected List<WebMarkupContainer> header = new
ArrayList<WebMarkupContainer>();
private AccordionPanel accordionPanel;
/**
* Constructor that is invoked when page is invoked without a session.
*
* @param parameters
* Page parameters
*/
public BasePage() {
accordionPanel = new AccordionPanel("accordionMenu");
add(accordionPanel);
add(new ListView("footerContent", footer) {
@Override
protected void populateItem(ListItem item) {
WebMarkupContainer webMarkupContainer =
(WebMarkupContainer) item
.getModelObject();
item.add(webMarkupContainer);
}
});
add(new ListView("headerContent", header) {
@Override
protected void populateItem(ListItem item) {
WebMarkupContainer webMarkupContainer =
(WebMarkupContainer) item
.getModelObject();
item.add(webMarkupContainer);
}
});
}
protected void addMenu(AccordionPanelItem accordionPanelItem) {
accordionPanel.addMenu(accordionPanelItem);
};
protected void addFooter(WebMarkupContainer webMarkupContainer) {
footer.add(webMarkupContainer);
};
protected void addHeader(WebMarkupContainer webMarkupContainer) {
header.add(webMarkupContainer);
};
Subs/Children then calls the methods... Problem with this technique is
that you need to use the right markup id's.. To make sure they are
always set, and giving full control to the child/sub on what to add, I'd
suggest that you create a BasePanel which encapsules the id, and then
required that instead of a markupcontainer, that way subs/child only
need to have panels that extend the basepanel...
But it depends on your needs, mine weren't that tricky..

could you share this technique? i think this might be a good idea.

On the other hand, I've also done something with listviews.. Allowing
sub pages adding markup items to menus etc.... Using the listviews as
place holders...

Ah, 'course! Should have thought of it, that's an option they mention
in "Wicket in Action".
However, Sebastiaan's solution can be reused in places where the markup
you have to change is not in <head>. -- Good to know.

The way I do it is; dont specify a title in your base page then just
add the
title in the subpage:
base page.html
<html>
<!-- anything shared in all the pages eg a base.css file -->
<head>
</head>
<body>
<wicket:child/>
</body>
</html>
subpage.html:
<wicket:head>
<title>hard code or use wicket label to add this</title>
</wicket:head>
<wicket:extend>
<!-- anything ... -->
</wicket:extend>
subpage.java

I am using markup inheritance (<wicket:child> and <wicket:extend>)
and need to set the
page title from my subpage. I currently add a label in the base class
(BasePage.java)
and make it use an abstract method getTitle(), which is overridden in
the subclass
(SubPage.java). Has anybody found a better way?
Here's my solution:
<!-- BasePage.html -->
<html>
<head>
<title wicket:id="title">[Page title]</title>
</head>
<body>
<wicket:child/>
</body>
</html>
<!-- SubPage.html -->
<wicket:extend>
<!-- anything ... -->
</wicket:extend>
public abstract class BasePage extends WebPage
{
// ...
public BasePage(final PageParameters parameters)
{
add(new Label("title", new PropertyModel(this, "title")));
}
public abstract String getTitle();
}
public class SubPage extends BasePage
{
// ...
public String getTitle()
{
return "whatever title";
}
}
