Re: recursive component
I'm sorry but reading that didn't help. I was not able to find the answer for my problem. Maybe I'm to tired. If I do this: -- Loop is used here -- this comes from the page markup -- this comes from the page markup Am I able to create pages like this? -- my panel -- caption for level1 -- content for level1 -- my panel -- caption for level2-1 -- empty content for level2-1 -- my panel -- caption for level2-2 -- content for level2-2 ... My problem is I don't know how to connect the panel instance with the right caption and content. Each node caption differs not in the data but also in the layout. And this is available also for the content.

Re: recursive component
Here's a basic treeview component i use (The backing models contain TreeNode
objects)
I made it abstract so the implementors just provide the fragment or panels
that represent nodes.
TreeView.java :
public abstract class TreeView extends Panel {
public TreeView(String markupId, final IModel rootNodeModel) {
super(markupId, rootNodeModel);
add(new TreeNodeView("node", rootNodeModel));
}
protected abstract Component newComponentForTreeNodeDescription(ListItem
markupContainer, String markupId, TreeNode treeNode);
protected abstract Component newComponentForTreeNodeChildren(ListItem
markupContainer, String markupId, TreeNode treeNode);
private class TreeNodeView extends ListView {
public TreeNodeView(String markupId, final IModel treeNodeModel) {
super(markupId, new LoadableDetachableModel() {
protected Object load() {
TreeNode node = (TreeNode)treeNodeModel.getObject();
List children = node.getChildren();
return children;
};
});
}
@Override
protected void populateItem(ListItem item) {
TreeNode currentChild = (TreeNode)item.getModelObject();
item.setOutputMarkupId(true);
item.add(newComponentForTreeNodeDescription(item, "node_desc",
currentChild));
item.add(newComponentForTreeNodeChildren(item, "children",
currentChild));
}
}
}

Yes. you are wrong.

Re: recursive component
Thanks for the answers. The only annoying thing is that I have to create a different panel for each node since the captions differ on each level. Or am I wrong?

Re: recursive component
hi stefan, The think is the markup is required to be like this. The only thing I'd like to reduce is the written java code. In short I'd like to create a reusable node component that I can configure (with populateCaption() and populateChildren() callback methods perhaps) just like the Loop :) martijns solution still applies - just make your own panels with the needed methods?! regards, --- jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: recursive component
Some corrections :) I don't need to generate wicket markup. The example is the desirable wicket markup that will support the dynamical generation. Each node component is thought as a Loop. The think is the markup is required to be like this. The only thing I'd like to reduce is the written java code. In short I'd like to create a reusable node component that I can configure (with populateCaption() and populateChildren() callback methods perhaps) just like the Loop :) The node structure is fixed: -- caption components -- -- children components -- I hope I was clearer this time :D Stefan On Wed, 2008-06-04 at 15:04 +0300, Stefan Selariu wrote: > Hi guys! > > I need to make generate something like this dynamically: > > > > > > > > > select > > > > > > > > > > > > > > > > > > > > > > This is a tree for which every node has a caption and children. > Can I create a wicket component for the tree node that supports my > example? > > I need a component that behaves like the Loop but in a recursive way :) > > Best regards, > Stefan > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: recursive component
RecursivePanel extends Panel {
public RecursivePanel() {
if(somecondition) add(new RecursivePanel("recurse"));
else add(new EmptyPanel("recurse"));
}
}

recursive component
Hi guys! I need to make generate something like this dynamically: select This is a tree for which every node has a caption and children. Can I create a wicket component for the tree node that supports my example? I need a component that behaves like the Loop but in a recursive way :) Best regards, Stefan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
