wicket:child
and wicket:extend
This is the most clean way of composing the pages content in Wicket.
01.
<
html
>
02.
<
body
>
03.
<
h1
>My Web</
h1
>
04.
05.
<
div
class
=
"content"
>
06.
<
wicket:child
/>
07.
</
div
>
08.
09.
<
div
>(c) 2010 Ondra.Zizka.cz</
div
>
10.
</
body
>
11.
</
html
>
1.
public
class
BaseLayoutPage
extends
WebPage { ... }
01.
<
html
>
02.
<
body
>
03.
<
h1
>Child page</
h1
>
04.
05.
DON'T get disturbed by this content, it's in examples only to confuse you.
06.
*** Everything outside "wicket:extend" will be ignored. ***
07.
08.
<
wicket:extend
>
09.
<
h2
>News</
h2
>
10.
So this is the real content to be included into the base page.
11.
12.
Here we have some component container:
13.
14.
<
div
wicket:id
=
"news"
>Works like usual, so this will be replaced by the component's stuff.</
div
>
15.
16.
<
wicket:extend
>
17.
18.
*** Again, everything outside the wicket:extend is ignored. ***

<

Label(

"Good news everyone!"
