Actionscript 3 :: Expanded Branch Do Not Show Its Children For First Time In Flex Tree?
Feb 11, 2011
I have added an event handler for itemOpening event for the tree component inside the handler basically ido myTree.selectedItem = event.item ; and then add the new data inside myTree.selectedItem.children.push(newData); But It do not show simultaneously instead I have to close , open the branch again to see the new data. I think I need to refresh something after adding new data but dont know what? below is the code but without the declaration , script tag etc
What I'm trying to do is have a 3 state tree expansion. I have three different icons for "expand" "collapse" "semi-expanded" which I want to use to show a partially populated tree control with all nodes initialized to semi-expanded state and then on clicking the "semi-expanded" icon it gets data from server and populates the tree and open that branch with "expanded" icon.
I tried looking for it but couldn't find anything close to it except the 3-state checkbox but don't know how to use it on 3 state icon when tree would only maintain 2 states.
I was wondering if anyone had access to source code that would allow me to draw lines between objects. I have examples of the standard one line between 2 objects.
What I'm looking for is an example of how to draw a branching line. I.e. Starts as a line coming from an object and then branches out to other objects. I don't want to draw multiple lines from the same object because I need the objects to be related and the lines to have a settable property.
The added issue is that I want the number of branches available to be settable by the user. But if I can find code that dooes the branching lines, it probably wouldnt be too hard to tweek.
I have a partially populated Tree component and I have to invoke a remote service when User expand (not when he select) a node to retrieve it's leafs. How I know witch node have bee selected.
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.
I'm using the iconField property of the Flex Tree to dynamically set the icon that a node should use. This works fine for leaf nodes but for branch nodes it doesn't seem to respect my iconField and instead just shows the default folder node.
I've created an mxml page that displays a tree control, however the data is only being displayed as branches. Even items that are leaves are being displayed as branches. <mx:Script> <![CDATA[ import mx.collections.ArrayCollection; public function init():void { var item:Object; var array:Array = new Array(); [Code] .....
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?
I've got a tree component which works great, but I'm trying to add an item at a particular location (immediately after the item they select) into the tree. The problem is that I'm trying to add an item within a branch. I'm using myTree.getDisplayIndex(myNode) to get the position within the tree, but it gives the location relative to the entire list, but I need to get the position relative to the parent (which is what myNode.parentNode.addTreeNodeAt is trying to write to)...
xml stuff in action script is so... non-intuitive.. cubersome I can compare it to the xml libs that I used in playground sdk, popcap and other .. tinyxml.. ....
I' m trying to make that simpliest thing for about 2-3 hours.. + reading books.. and still can't do it..
what I want to do is: <xml> <Weapons> <Weapon id="canon" rechargeTime="200" impulse="30">
[Code].....
how do I read the all "Weapon" objects listed inside Weapons.. NOTE: I dont want to use the method.. that returns "Weapon" from all over the xml... cause I probably want to list weapons in other sections for other purposes
I am working on a tree component and I am having a bit of the issue with populating the data-provider for this tree.The data that I get back from my database is a simple array of value objects. Each value object has 2 properties. ObjectID and ParentID. For parents the ParentID is null and for children the ParentID is the ObjectID of the parent.
Essentially the tree should look something like this:
I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?
I get the folder icon, never the label. I've tried numerous datasources, always the same thing. File, ajax call, text, it always fails.
In the code below I even set a custom handler and watch the XML come in, I set a static text label going out. Never anything shown. This happens without the label function and using labelField. Yes, I'm 100% sure the attribute matches. Again, tried with numerous different datasources.[code]...
I have an xml file it's structure like down below :
[Code]...
I looked for couple of examples It uses Xml attributes to shows as tree components' labels. But I want to show these xml text contents in tree component. But i couldn't find an example how to show as label these xml text contents.
Using RecursiveDirectoryIterator of PHP i am able to create directory tree and can even flatten it using RecursiveIteratorIterator class , but I want to create directory tree structure which TREE component of flex understands . The following is an array structure in php which flex understands.
If I've got a Container with a child component that is off either the top or the left hand side:
Is there any way to get scroll bars to show up? ie, so I can scroll up and get the button back in view, the same way I could if the button was off the bottom right side?
I have a viewstack with childrens which I want to show/hide depending on the state the application is
[Code]...
AS you can see I inlude the retail customer view in the retail state and the wholesale customer view in the wholesale state. The problem is that when I run my app they don't appear on neither state.
I want to basically copy an xml object I have created, take the children from a specified node and make a new xml object from them and put this new xml into the tree component. Can you see what is wrong with this?
I have a tree being populated by an array collection. I don't have control of the data in the array collection and even when a node has no children it still has a "children" property that is causing my tree to treat every node as branch. I can do a simple check on the length of the array in the children property. If this is 0 I need the tree to display the node as a leaf, no disclosure icon. Any thoughts on how I can achieve this? It would be nice if there were a branchFunction like the iconFunction and labelFunction.
I have a tree using an ArrayCollection/Object data provider. The following code worked with an XML data provider but won't work with the non-XML data provider:
I am working on Air application,i had a problem on Tree control.Iam adding nodes for the tree dynamically, while adding nodes to the tree i am setting Tree.selectedItem as present added node. after that i need to fire Tree.itemClick event handler method also.how can i call event handler method as a common method. in Flex3
I am facing some problem that I add some title widows to the ItemRenderer of tree. but some time tree don't show those tiny title windows in tree item-renderer.. is this the issue that tree re-use its renderers..(these windows are skinned like little cricles, and added specific to the data of item renderer.. these TitleWindows are added using addElement() to a s:BorderContainer in the renderer)[code]...
