Create custom component
Dear all,
Is there any tutorial on creating custom component in Wicket? The ones
I found only shows creating custom component by extending from the
existing component but not creating from scratch. If anyone has
created those tutorial, can anyone here please point me to there.
Thanks in advance

Hi Eelco,
Thanks for the response.
Maybe tutorial doesn't sound good, but I think this kind of
information you've written here is important and worth written on the
wicket wiki.
Thanks.

It doesn't make sense to have such a tutorial. You need to decide what
you'll be building and what base class comes closest to what you want.
WebComponent is the absolute base class (for web applications) that
don't nest other components (Labels) and WebMarkupContainer is the
base for pretty much anything else. If you need markup attached, you
would start with Panel or Border, and if your component needs to work
in a form, you would extend from at least FormComponent. And then
there is Repeater for anything that 'repeats' and the tree base
classes. All very different cases, but what they have in common is
that you just extend their Java classes, customize by looking at their
APIs (particularly at what abstract/ protected methods there are) and
maybe plugin some behaviors.

Yes that's what I mean, I couldn't find document on creating custom
component that extend from Component.
Ok I'm gonna try looking at the existing component and try build my
own component from there.
Thanks.

What do you mean by "from scratch"? All Wicket components
extend Component.
You could just look at any existing Wicket component, it's
anyway a good idea to have Wicket sources attached to your
IDE and they are all there.
Best wishes,
Timo
