How to make Page support mutil level inheritance...
Hi everybody,
The subpage can extends parent page via overriding the getTemplate()
method and get all feature in the parent page ..
How to make mutil level inheritance?
For example, a Detail page in include header, content, footer section, I
want to split content into tow area, the sidebar and the main content.]
So I design a DetailPage include header, footer, a Content page extend
the DetailPage and include the sidebar , the CompletePage extends the
Content page and include main content area.
How to implements this, if not use panel??

Hi Hantsy,
By default Click uses Velocity to implement the inheritance so only one $path variable is available
inside the template. However you could use another variable name to implement what you want:
Border.java:
public class Border extends Page {
public String getTemplate() {
return "/border.htm";
}
}
border.htm:
...
<!-- Parse the Sidebar template -->
#parse($template2)
...
Sidebar.java:
public class Sidebar extends BorderPage {
public void onInit() {
String path = getContext().getPagePath(Sidebar.class);
addModel("template2", path);
}
}
Complete.java:
public class Complete extends Sidebar {
}
complete.htm:
...
#parse($path)
...
You can also use Velocity #if to conditionally parse $template2 or $path etc.
kind regards
bob
