Re: [Wicket-user] Wrap a component through a visitor?
If I have markup as such:
div wicket:id=myParent
input type=submit wicket:id=myButton/
/div
My goal is to have output as such:
div wicket:id=myParent
div class=foo
input type=submit wicket:id=myButton/
/div
/div
I'm basically trying to wrap the button component with some markup via
a visitor. What it get's wrapped with wouldn't need to have any logic
with it, it could be a simple string prepend/append.
Cheers,

Re: [Wicket-user] Wrap a component through a visitor?
the problem with doing this through components is that your markup hierarchy will be out of sync with your java one.what you can try is making myParent a AbstractOutputTransformerContainer and then doing string manip in the transform() method by wrapping the output.
its not purty, but it will workor you can just add class=foo to myParent via an attribute modifier and save a lot of trouble :)-igorOn 11/13/06,

if you just want div around the button MyButtonyou can use a border i guess (i don't like the current borders to much i would like to make them like swing borders)butButton myButton = new Button(myButton)
{ protected void onRender(MarkupStream stream) { getResponse().write(div class=foo); super.onRender(stream); getResponse().write(/div);
}}Thats how borders should work i guessWhat i would like to have is:MyBorder border = new MyBorder();MyBorder.htmlwicket:borderdiv class=foo

Re: [Wicket-user] Wrap a component through a visitor?
thats is exactly how swing worksI have always find the wicket borders counter intuitive . (border contains/has components instead of a component has a border)But i don't say lets replace the current border thing.
But maybe add IComponentBorder to wicket 2.0And yes if you then want to wrap multiply components then you have to do it like swing, add first those in a markup container/paneljohan
