Adding Panel(s) at Runtime (dynamically)

[mehdi b <me...@yahoo.com>]

Hi all,

I want to add some panels to my web page and the number of panels is unknown. I want a <div wicket:id="cont"></div> in my template page and add needed panels to this div (the number of panels is determined at run time).
Besides, I want a surrounding <div class="a"></div> for each dynamic panel on adding it to the page.

Thanks

//HTML
<div wicket:id="panelListView">
<div wicket:id="runtimePanelItem"></div>
</div>

your ListView model which is expected to be a List, determines the number of
Panels to be dynamically created
//Java

ListView panelListView= new ListView("panelListView", model){
   public void populateItem(ListItem item){
      SomeModelObject object = item.getModelObject();
      if(bla bla bla)
      item.add(new MyRuntimePanel("runtimePanelItem"));
      else
      item.add(new MyOtherRuntimePanel("runtimePanelItem");
   }
}

infact you can insert some logic inside the ListView to determine which
specific panel to add dynamically.

Hi,

Use a ListView or some other Repeater-component and implement a model 
that returns a list of the classes that should be created as panels. If 
you need a wicket:id on the surrounding div, that's fine, but not 
needed. You would then do

WebMarkupContainer cont = new WebMarkupContainer("cont");

Then you add the ListView to cont component istead of the page.

Also, you would use the div with class a as the "base" for each listItem:

<div class="a" wicket:id="conts">Panels here</div>
