Re: [Wicket-user] Tree - override onNodeLinkClicked(...)?

[kenixwong]

ok... maybe i m new to wicket. Some of the example i cant really get what it
means. Anyway, for temporary, i had solved my problem (think is not so
practical :p) . hard code for the node link..


protected void onNodeLinkClicked(AjaxRequestTarget ajaxRequestTarget,
TreeNode node)
  {
  treeNode = (DefaultMutableTreeNode)node;
  String treeNodeIndex = tree.getNodeComponent(node).getId();
  System.out.println(" treeNodeIndex = "+treeNodeIndex);
  if(buildTreeList.size()>0){  
  // tree- root
  if(tree.getNodeComponent(node).getId().equals("0")){
  ReportsPortalPage page = new ReportsPortalPage();
  setResponsePage(page);
  }
  // request module
  else if( tree.getNodeComponent(node).getId().equals("1")){
  RequestReportsPortalPage page = new RequestReportsPortalPage();
setResponsePage(page);
  }
  //hardware module
  else if( tree.getNodeComponent(node).getId().equals("5")){
  HardwareReportsPortalPage page = new HardwareReportsPortalPage();
setResponsePage(page);
  }  
  //software module
  else if( tree.getNodeComponent(node).getId().equals("9")){
  SoftwareReportsPortalPage page = new SoftwareReportsPortalPage();
setResponsePage(page);
  }
 
  //admin module
  else if( tree.getNodeComponent(node).getId().equals("13")){
  AdminReportsPortalPage page = new AdminReportsPortalPage();
setResponsePage(page);
  }
 
 
  }
 }

At the moment, it works. But in future , i will study and amend it. Thanks
for everybody :)


Here, i got another question... is there any place to enlarge the tree
border size ? Caused by some of the node link name is long (eg: Workstation
Network Card Details Report (PDF) ) , when the tree was expand, i cant see
the whole name ... As i looked for the wicket example, it was automatic..
but when i implemented it, it is not ? 

thanks

Re: [Wicket-user] Tree - override onNodeLinkClicked(...)?

[Matej Knopp]

I believe, that what you want, is not to set response page, but rather
to switch panel components. At least that sounds much more reasonable
to me.

Re: [Wicket-user] Tree - override onNodeLinkClicked(...)?

[kenixwong]

the reason i using the tree is my menu will be cover a lot of reports ( i m
develop the report module). So if using the tree style, the interface will
be look more nicer and structure. Plus the dynamic feel to the user :p (more
attractive). is that the wicket - tree is hard to maintain? Actually i had
build the tree, sub tree and report name. All i listed in array and then
called up the array to execute became a tree.

Anyway, i found that the wicket example did not show the use of the node
link. Any place can help ? As i went through this forum but still cant get
any idea to solve it .. :( how ar??

If you are looking for menus, why not use something like this:
http://developer.yahoo.com/yui/menu/? That will be much easier to set
up than bending the Tree component into something it is not meant for.

If you are just playing around, could you please do that with Wicket
1.3, as you won't have those problems you are having with that version
to start with :) See

Sorry, cant get u.. can you show me the some partial code ? My tree example
was refer from the wicket example. but it only shown how to create a tree
without some example to click the node and redirect to another page. I had
tried search from the forum and do testing... still failed. Can everybody
give ma some guide ? Maybe i am new to the wicket.. anyway, it is fun to
learn and play around :)

thanks

in wicket 1.2.x we do not support setresponsepage() from an ajax request
(which is what i assume is going on since setresponsepage isnt working).
what you have to do instead is

ajaxtarget.appendjavascript("window.location="+urlfor(MyPage.class));

So calling setResponsePage (to another page I pressume) doesn't work
in the link clicked handler of the tree component? I wouldn't know how
this might be a problem tbh.

Which version of Wicket are you using, and which tree component (from
the core project or the extensions project)?

Re: [Wicket-user] Tree testing

[Ingram Chen]

indeed, we internally develop small extension to allow using partial path
to allocate component.

tester.clickLink("foo:bar:navigation:i:6:nodeLink")
can be written like

tester.clickLink("foo, 6, nodeLink")

And instead of using the full path like that (which can be
tedious to maintain when the component hierarchy changes)
you can also use an Ivistor to access the component (and
then ask its path from itself).

It depends on the case which is wiser. We also use a the
hardcoded path a lot in tests, but with repeaters it can
get a bit fragile.

Thanks Frank, thanks Ingram!

Didn't know that I could just access the links like that. But it seems 
quite logical.

Everything works as expected now.

Thanks again!

Hi

I haven't used the tree yet (and therefore not tried to test it). But what
do you do. I would just imagine it would be a call to tester.clickLink
(linkPath)?!

Re: [Wicket-user] Tree with add/delete/edit nodes

[James McLaughlin]

Hello,
You can do this through the ITreeState
(tree.getTreeState().getSelectedNodes ()). Also, you can register with
the TreeState as an ITreeStateListener and implement the
nodeSelected(TreeNode node) method.

jim

Re: [Wicket-user] Tree with add/delete/edit nodes

[James McLaughlin]

Hello,
I've just done this, works like a charm. Use a DefaultTreeModel for
your tree, and when it comes time to insert / remove nodes, just use
the appropriate methods on DefaultTreeModel. If you are doing this
with an ajax tree, you will want to call updateTree(AjaxRequestTarget)
after. If you are adding to a leaf node, you will want to call
getTreeState().expandNode(node) on the parent after the call on
DefaultTreeModel and before updateTree.

jim

I have searched the archive and the last time someone asked about this seems
to be 2006.  We are new to wicket and were impressed with the Editable tree
table example. We wanted to try to create a tree display that lets the users
edit the nodes of the tree by adding a button to add a child node or delete
a node. I was wondering if anyone had accomplished this or attempted by
found it problematic.

//testPanel.setOutputMarkupId(true);
//add(testPanel);
}

protected TreeModel createTreeModel() {
...
// code copied from examples
   ...
}

}


For Tree I've used code and model from SimpleTree from ajax examples.
For Panel I have ths code:

TestPanel.java
public class TestPanel extends Panel {
public TestPanel(String id, TestPanelBean tpb) {
super(id);
add(new Label("text", tpb.getNodeName()));
}
}

TestPanel.html
 

  
Text:--node--




TestPaneBean.java (which holds text to be displayed in TestPanel)
public class TestPanelBean {
private String nodeName;

public TestPanelBean(String nodeName) {
this.nodeName = nodeName;
}

public String getNodeName() {
return nodeName;
}

public void setNodeName(String nodeName) {
this.nodeName = nodeName;
}
}


So, even a set:
target.addComponent(testPanel);
testPanel is not refreshed. :(

For now, I want to display node name in the panel. In the future, I'll like
to instantiate different panel components regarding to clicked tree node
type (if node represents image, show that image information and so on).

[Wicket-user] Tree and Panel - refresh problem (1.3b1)

[Vatroslav]

Hi,
I'm trying to update (refresh) Panel from Ajax tree (by clicking tree item)
but without success. :(
I've checked, Panel's model is changed.

If I put a Label component instead of Panel, and inside
onNodeLinkClicked(AjaxRequestTarget target, TreeNode node) method modify
Label's model and then refresh Label with target.addComponent(myLabel);
everything is OK.

But I can't do that with Panel component.
Why??

Thanks,
vatroslav

Re: [Wicket-user] Tree Node's Refresh Issue

[Igor Vaynberg]

but if you dont really care about the web2.0 kiddies you can do it the old
fashioned way as well - via javascript.

class addnewitempage extends webpage implements iheadercontributor {
 private boolean itemadded=false;

 form f=new form(..);
 f.add(new button("add") {
onsubmit() { ; itemadded=true; }
 }

 public void renderhead(response response) {
   if (itemadded) {
 response.addonwindowloadjavascript("window.top.leftframename.refresh
();");
 itemadded=false;
   }
 }
}

this assumes your additem page navigates back to itself. if not, adjust
accordingly.

[Wicket-user] Tree Node's Refresh Issue

[Sridhar.N]

Hi,
I have a user interface which is having 2 frames. In the left frame I have
the dynamic tree which is populated dynamically from database on click of a
node. I have links on the nodes which refreshes the right frame with
appropriate pages.My problem is, when ever a new item is added to the DB
from the page in the right frame I want to refresh the tree's node which is
there in the left frame with the newly inserted value without refreshing the
whole tree.

Thanks in advance.
Sridhar.N

Re: [Wicket-user] Tree persistence problem

[Renan Camponez]

This doesnt works.. :(

Now, when I click on the Ajax Link for the second time, the Main page is
showed inside the ModalWindow, instead of the page who has the tree.

Following, the code:

I have a Main page, who has this modal window, and the Ajax Link:

modal = new ModalWindow("modal");
modal.setPageCreator(new ModalWindow.PageCreator(){
   public Page createPage()
   {
   Page nav = ((AppSession)getSession()).getNav();
   if (nav == null){
   nav = new Navigation(Main.this);
   ((AppSession)getSession()).setNav(nav);
   return nav;
   }
   else{
   return nav;
   }
   }
   });

ibNavigation = new AjaxLink("ibNavigation");

The onClick event for the Ajax Link: modal.show(evt.getAjaxRequestTarget());

The part of the code when the Tree is instantiated:  tree = new Tree("tree",
createTreeModel());

Any idea?
Thanks

[Wicket-user] Tree persistence problem

[Renan Camponez]

Hi all,
Here is my problem:

I have a Ajax Link who shows a ModalWindow (modal2.show(
evt.getAjaxRequestTarget());) when clicked.
Inside this modal window, I have a
wicket.extensions.markup.html.tree.Treeobject.

The problem is: The user "changes the status" of this Tree (collapsing the
nodes), then closes this ModalWindow.
When the user clicks again on the AjaxLink (and the ModalWindow is showed
again), my Tree object looses the status (meaning all the user modifications
on nodes) is missed...

Anyone, have any idea on how to make the tree status persistent for me?

Thanks!

Re: [Wicket-user] Tree for navigation

[Eelco Hillenius]

The best way to do this is to ignore the Tree components we ship. What
you're after here is either something similar to
https://svn.sourceforge.net/svnroot/wicket-stuff/branches/WICKET_1_2/wicket-contrib-navmenu
or something based on a javascript (client side only) tree.

I have the same question, and I'd like to add to it by asking how to keep
the tree expanded, rather than collapsing every time a node is clicked?
Here's how I did it, but I suspect there are better ways:

I built the tree starting from the example in the extensions (although I
used wicket.extension.markup.html.tree.Tree, not the Ajax version):

private TreeModel createTreeModel()
{
DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode(
new ModelBean("MyNode", MyPage.class));

// My model bean stores the page class to which I want to navigate.

rootNode .add(new DefaultMutableTreeNode(new ModelBean("MyNode2",
MyPage2.class)));
...
TreeModel model = new DefaultTreeModel(rootNode);
return model;
}

public MyBasePage()
{
Tree tree = new Tree("tree", createTreeModel())
{
@Override
protected void nodeLinkClicked(DefaultMutableTreeNode arg0)
{
super.nodeLinkClicked(arg0);
ModelBean bean = (ModelBean) arg0.getUserObject();
if (bean.getLinkClass() != null)
{
   
MyBasePage.this.setResponsePage(bean.getLinkClass());
}
this.expandAll(true); // I want the tree to stay
expanded...is this the best way?
}
};
tree.expandAll(true);
add(tree);
}

[Wicket-user] Tree for navigation

[Nicolai Dymosz]

Hi All,

i built a tree (wicket.extension.markup.html.tree.Tree). The tree works fine. 
But now i want to use the tree for navigation. 

I just found examples to build a tree, but i didn`t find some examples to use 
the tree for navigation.

Can anyone give me further information in how to make tree links bookmarkabel?

Regards Nico

[Wicket-user] Tree node clicked to change another panel problem

[yaojb]

I’d used Tree component(id=”tree”)
as navigation layout, I want to change another panel component(id=”main”)
of the same layout when one tree node clicked, But nothing change occur. When I
use the link component to change the same panel component(id=”main”)
followed the nested demo of wicket-example, so it’s ok! Oh, how can I get
the same effect use Tree component???

Re: [Wicket-user] Tree scrolling

[Matej Knopp]

Yes, but consider that you want to have border (non-scrolling) around 
your tree. So you'll have to put overflow:auto to a element outside tree 
(the one with border and width set).

One more thing. Instead overflow:scroll it would be better to have 
overflow:auto.

Scrolling shouldn't be a problem.


  
  


Well. In 1.2.2 there was a problem with internet explorer in standard 
compliance mode, images were staying even if tree scrolled. In current 
svn this is fixed. Can you please try current 1.x from svn?

Ok, I just noticed that the tree component has built-in scrolling, but the problem remains valid.  The images don't scroll...at least not in IE.  In Firefox, the scrollbars don't even show up.

Yep. Override getCss:

protected PackageResourceReference getCss()
{
return new PackageResourceReference(FooTree.class, "bar.css");
}

Also note that since a few days (will be in 1.2.2) there is a new tree
component put in extensions for 1.2.x, and will replace the tree in
core for 2.0. That tree is leaner and meaner, and has very nice
features like running in ajax mode etc. You might want to check that
out. They both work with Swing's TreeModel.

I have no idea, your code looks fine to me. Did you try pasting in
your model in e.g. wicket.examples.nested? See if that works... it's
probably something small and stupid that is overlooked here.

[Wicket-user] Tree not shown correctly

[Rice Yeh]

Hi,  I write a tree component by extending wicket.markup.html.tree.Tree. Also I extend the javax.swing.tree.DefaultTreeModel. I have my TreeModel tested in swing. It works fine. However, my tree just show the root node in wicket. What is going wrong? I have my code attached.

Re: [Wicket-user] tree model

[Арву Оетук]

Thank to all for replays.

Yes,Johan, this solve problem.
But too many methods in DefaultMutableTreeNode.
I think better way exist.
I create subclass that have loadAllChildren() method. Methods like children() 
or getChildCount() will call loadAllChildren()
Dmitry.

Re: [Wicket-user] tree model

[Eelco Hillenius]

Just looked into it a bit. The problem is that the TreeNode interfaces
really don't define enough behavior. Like getPreviousSibling,
getNextSibling, getPath, getLevel, preorderEnumeration and
getUserObject are all used in both Wicket's tree and Swing's Tree, and
they are only defined in DefaultMutableTreeNode.

That looks strange to me.i have used my own implementations. Where does the class cast exactly come from?But still you could use DefaultMutableTreeNode just fine for lazy loading.Just don't give him childeren yet. Do that only when ask for (override the right methods like

Re: [Wicket-user] tree model

[Eelco Hillenius]

It inherited that problem from Swing's Tree component. Don't ask me
why, but even though there is this TreeNode interface, Swing's Tree is
not really usuable with anything else than DefaultMutableTreeNode.
Unless I missed something.

Absolutely!  The ability to drill-down into a data structure without

I want use big tree model.
But I don't want load all tree in memory.
Is it possible use TreeNode instead DefaultMutableTreeNode?
Or other way exists?

[Wicket-user] Tree images

[Dzenan Ridjanovic]

Martijn,

I am using Wicket 1.1.-b2 release. Yes, I use the Wicket jar from rhe 
distribution.


Dzenan


Dzenan,


The Tree component itself has images (see source pasted below). I don't 
know why you get a NPE though. What kind of Wicket set up are you using? 
Do you use the wicket jar from the distribution, or did you build one 
yourself?
