I've been doing this very thing right at the moment, and once you get your
head into actionscripting its actually quite easy.
set up your CFC to return a query...
<cffunction name="getCategories" access="remote" returntype="query">
<cfquery name="categories" datasource="test" dbtype="ODBC">
SELECT group_id, group_name
FROM groups
WHERE active = 1
</cfquery>
<cfreturn categories>
</cffunction>
then in your flash MX movie, ensure you have flash remoting properly setup
and include the following in the first frame:
#include "NetServices.as"
if (gatewayConnection == null) {
NetServices.setDefaultGatewayUrl("http://localhost:8500/flashservices/gatewa
y");
gatewayConnection = NetServices.createGatewayConnection();
CFMService = gatewayConnection.getService("componentdir.componentname",
this);
}
you may need to change some of the above....
then call your CFC function:
CFMService.getCategories();
and build a _Return function to handle the incoming data (in it I reference
an fTree component instance on the stage named 'catTree'):
function getCategories_Result(result) {
_root.catTree.setEnabled(true);
_root.treeRoot = new FtreeNode("Categories");
_root.treeRoot.setDataProvider(result, "group_name", "group_id");
_root.catTree.setRootNode(_root.treeRoot);
//_root.catTree.setDataProvider(result);
_root.catTree.setAutoHideScrollBar(true);
_root.catTree.setSize(300,400);
_root.treeRoot.setIsOpen(true);
_root.catTree.refresh();
}
there we go! Flash displays all my categories in the tree component (and you
can add a clickHandler to handle what happens when a node is selected). You
can change the appearance of the whole thing (although I'm not going into
that here) and you can add child nodes to other nodes etc. Look at the
reference window for the fTree component and you'll see all its methods
available to you.
I'm still learning myself, so the above may be stylistically yucky, but it
the idea is right.
