Following this post about Tree control, I have a question.

Here is a piece of code from CodePeek AIR app.
Mediator method triggered when the user clicks on any item of the search Tree :

:

protected function onTreeItemSelect( event:Event ):void
{
    if ( app.tree.selectedItem.@url == undefined ) {   
      sendNotification( ApplicationFacade.SEARCH_TYPE_SELECTED, app.tree.selectedItem );
    } else {
      sendNotification( ApplicationFacade.SEARCH_SELECTED,[ app.tree.getParentItem( app.tree.selectedItem ), app.tree.selectedItem ] );
      app.browser.location = app.tree.selectedItem.@url;
    }
}
To know if the user clicked (in the search tree) on a Language or a Search keyword, CodePeek looks for a "url" attribute in the item : if no url attribute is found, it means that a Language (folder) was clicked...

Is there another way of doing this ?

How can I know the name of the XML tag of the clicked item ?

thanks in advance,

Hi Cliff,

I just downloaded CodePeek source code. I'm sure I'll find everything I need.
Thanks a lot for you answer.

Hi,

I am building my first Flex/PureMVC application to get a nice picture of the framework.

I don't find simple information about how I could represent a tree structure in my model...

I found examples of proxies manipulating simple VO as their "data", or ArrayCollection, but how could I manipulate (in proxy I suppose) and store (in proxy's data) a tree of objects.

My sample is quite simple: represent a shop, with products arranged in categories.
The tree is a set of categories, each category can contain subcategories and/or products.

[DVD]
  [Drama]
    .National treasure
    .The walker
  [Animation]
    .Toy story
[Books]
  .Learning AS3
  .Design Patterns

I suppose my Proxy would expose methods like getCategories, getProductsForCategory, etc... These methods returning stuff from the data var of the proxy.

Last but not least, I have a Tree control in my view component. How can I use Bindable to fill my Tree control with the data retreived by the mediator (through a notification sent by my proxy) ?


(don't forget I am not yet familiar with the framework)

Thanks for any response,
