launching a modal page from a Panel

[Elad Katz <el...@xtify.com>]

Hi all,
I need to launch a modal from a panel.
I saw the examples
http://www.wicket-library.com/wicket-examples/ajax/modal-window but they
were very complicated for what I need and didn't show how I can launch it
from within a panel.
Let me try to explain:
I have a datatable where one of the columns is defines like this:

        columns.add(new AbstractColumn<LocationsEntity>(new
> Model<String>("Edit")) {
>
>             public void populateItem(Item<ICellPopulator<LocationsEntity>>
> cellItem, String componentId,
>                     IModel<LocationsEntity> model) {
>                 cellItem.add(new EditActionPanel(componentId, model));
>             }
>         });

Now the EditActionPanel is a panel that basically shows a link, and is
defined like this:

> class EditActionPanel extends Panel {
>
>         /**
>          * @param id
>          *            component id
>          * @param model
>          *            model for contact
>          */
>         public EditActionPanel(String id, IModel<LocationsEntity> model) {
>             super(id, model);
>             add(new Link("edit") {
>
>                 @Override
>                 public void onClick() {
>                     selected = (LocationsEntity)
> getParent().getDefaultModelObject();
>                     *HERE IS WHERE I NEED TO CALL A VERY SIMPLE
> YEN/NO/CANCEL MODAL *(are you sure you want to edit? y\n\c)
>                 }
>             });
>         }
>     }


Can you guys please tell me what is the line I'm missing?
I know it sounds trivial, but I've been battling this all day and i could
really use some help on this
Thanks allot in advance,
E.

Of course. If it is a panel then you'll do the same thing.

class MyPanel extends Panel{
   class variable....
}

Define your modal window as a class variable.

class MyWebPage extends WebPage{
  private ModalWindow myWindow;

}

in the constructor

myWindow = new ModalWindow( "myWindow" );
myWindow.setPageMapName("myWindow-1");
myWindow.setCookieName("myWindow-1");
myWindow.setPageCreator(new ModalWindow.PageCreator() {
  public org.apache.wicket.Page createPage() {
    return new MyWindow();
  }
});
myWindow.setWindowClosedCallback(new ModalWindow.WindowClosedCallback() {
  public void onClose(AjaxRequestTarget target) {
  }
});
myWindow.setCloseButtonCallback(new ModalWindow.CloseButtonCallback() {
  public boolean onCloseButtonClicked(AjaxRequestTarget target) {
    return true;
  }
});
add( myWindow );


Now, all you have to do is to call myWindow.show() in your ajaxlink.
