I am still having some tree / array issues that I am hoping to get some help
on. My tree loads an array of data that looks like this. Items with a
children array tell me that this folder should be a branch and it has
children. When you click on the branch I want to go retrieve the list of
directories for that folder and update the array with the new directory
data.
(Array)#0
[0] (Object)#1
lastModified = 1225560062218
name = "bin"
parent = "H:\JRun4"
path = "H:\JRun4\bin"
[1] (Object)#2
children = (Array)#3
lastModified = 1186192523437
name = "docs"
parent = "H:\JRun4"
path = "H:\JRun4\docs"
My itemOpen listener event basically get the path of the folder being opened
and fetch the directories for that path.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.item.path;
holder = event.item.children;
FileManager.getDirectories(path);
}
When the list of directories is called this method is the result handler. IF
the tree data provider is null we know its top level. What I thought I could
do is setup a variable called holder that would the array object of the item
above. I thought this would pass the reference of that object and using that
reference i could set the new dirs into that empty array. This is not really
working so I was wondering if anyone has some ideas or what the right
approach should be.
private function listDirectories(event:ResultEvent):void {
var dirs:Array = event.result as Array;
// if the _directories array is null this is our root
request
if(_directories == null) {
_directories = dirs;
}else {
// what do we do now?
holder = dirs;
}
}
Thanks for the help!
