Re: Wicket Markup side-by-side
I agree; Wicket and JQuery cannot substitute each other. My apologies if I was not clear enough. Here is little history: Actually I was going through JQuery Ajax events and other basic tutorial and wanted to understand Wicket7's Ajax Event handling and HeaderItems - just to compare and learn how Wicket changes the final markup against the final markup using plain JQuery. At one point I was stuck as I was using wrong HeaderItem in Wicket to achieve same what I was doing with JQuery function in plain html to hide the link on click. Using one particular HeaderItem was not resulting in similar JavaScript function after markup which I had using plain JQuery function. That made me curious to know and compare final HTML markup side by side by using straight forward JQuery/JavaScript and then doing same thing with Wicket by setting different HeaderItems; to understand how setting different header effects the final Markup and know internals of Wicket HeaderItem from there. For example, what markup looks like when using JavaScriptContentHeaderItem (and when to use it), or how it would look when using OnLoadHeaderItem? And then comparing the final markup against plain HTML written with JQuery/Javascript function. Not much of use may be; but just wanted to get more insight of how Wicket HeaderItem and Ajax Events works; with comparing those against vanilla JQuery/JavaScript usage. I hope this explanation would help in understanding my original question. Thanks, -Mihir.

Re: Wicket Markup side-by-side
Hi, What kind of examples/snippets do you have in mind? Wicket cannot substitute jQuery, and vise versa. For better user experience I'd recommend to use JavaScript (jQuery) when possible. E.g. using AjaxLink when you can use plain JS for some interaction is actually bad practice.

Wicket Markup side-by-side
Hello, I recently started digging little deeper into how Wicket 7 converts/generates markup when adding JS or CSS resources at the page/component level. And that gave me an idea of contributing to the wicket community by showing code snippet (side-by-side) with pure JQuery and then how to achieve same with Wicket 7 (and resulting markup). I am not sure if there is already a place available for such or if anybody is working and I could join the efforts. Any suggestions/recommendations? Thanks, -Mihir.

Re: Wicket Tree - Getting The Selected Node
Hi,
@Override
public Component newContentComponent(String id, IModel model)
{
return new Folder(id, this, model)
{
/**
* Always clickable.
*/
@Override
protected boolean isClickable()
{
return true;
}
@Override
protected void onClick(AjaxRequestTarget target)
{
Employee employee = getModelObject();
// keep selection somewhere, exchange components or
switch to other page
}
@Override
protected boolean isSelected()
{
// get selected status somewhere
return false;
}
};
}
Have fun
Sven

You decide how to represent each node's content, for this you'll have to
override AbstractTree#newContentComponent(). The default will just
expand and collapse the tree branches on each click, see
org.apache.wicket.extensions.markup.html.repeater.tree.content.Folder
You can override Folder's methods or use any other component to
represent your nodes.
Thanks Sven. I have understood the above as I can see the expanded nodes by
inspecting tree.getModel(). What still foxes me is how do I take some
action, when the user clicks a particular node? For example if each node is
representing an employee, then how can I display the details of the desired
employee when the user clicks/selects on the corresponding employee node?

Anup
