Flex :: Add A Node To Tree Without Adding It To DataProvider?

Feb 23, 2010

I've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.

It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?

Flex :: Override Child Node Controls In A Flex Tree Control?

Aug 20, 2010

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:

private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....

I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?

override protected function createChildren( ): void
{
super.createChildren( );[code]............

Here is my tree tag:

<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />

Flex :: Make A Copy Of A Tree From The Root Node?

Feb 16, 2011

I have inherited a Flex air project and have not worked with trees before. The tree is displaying an xml file hierarchically. The user can make a change to the data. I need to save the data of the entire tree to a file.I can save the currently selected item to a file, no problem. But I need to save all the data from the root of the tree, forward.I would think I could make a copy of the tree, and set the selected item of my new tree to root, or something. Sort of like this pseudo code:

var treeToSave:Tree = new Tree (editedTree);
treeToSave.selectedIndex = 0;
// now save treeToSave to file...

This creates a compile error, but hopefully you can see what I'm trying to do.

Flex :: Dynamically Change Tree RowCount If A Node Is Expanded?

Dec 27, 2010

The tree should have a minimum row count of 4 and a maximum of 10 (beyond which it should display the scroll bars). So, I have a tree with rowCount="4" and I want rowCount to change up to "10" depending on the currently expanded nodes. In debug I can see two of the tree's properties which I could use[code]...

But these are not accessible from outside so I can't find a way to understand if the tree is expanded or not.

Flex :: Select Tree Node Right After The DataProvider Is Been Assigned / Updated / Replace?

Jan 26, 2011

i have a Flex tree control and im trying to select a tree node 3 levels down right after the dataProvider is assigned with a collection object like the following.basically treeItem1, treeItem2, treeItem3 are the nodes in the tree and treeitem3 is a child of treeItem2 which is a child of treeItem1. Assume these treeItem(1,2,3) are referenced correctly from the collection items.

my problem is that if i wait for the whole component to load completely then select the nodes, it open/select/scrolltoIndex correctly. However, if i were to select the node right after the dataProvider is assigned, then it doesn't even open or select (basically the this.treeService.selectedItem is always null).

this.treeService.dataProvider = oPricingHelper.getCurrentPricingSercicesTreeSource();
this.treeService.expandItem(treeItem1, true);
this.treeService.expandItem(treeItem2, true);
this.treeService.selectedItem = treeItem3;
this.treeService.scrollToIndex(this.treeService.selectedIndex);

Flash :: Flex 4.5: Tree - Make A Flex Tree Component Display The Children Of A Sprite In A Hierarchical Way

Nov 19, 2011

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
