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";
}
}
