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'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 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
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)...
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 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 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 have a intro to a picture of a tree which has buttons on it. The intro is an embedded flv video (not using the FLV component). The video starts on frame one and runs to frame 2. The tree is on frame 3.When I click a button on the tree, it runs the respective frames then returns to the tree. When the tree appears, the sound of the video is playing in the background.How can I make this stop?
I have a file that I've been working on, and i want to take what I have and modify it heavily, but I want to keep the original; if there was a 'duplicate' project command I would do that, but I don't see one, and wondered if there might be a way to keep it all in the same project for tidiness purposes. I'd just copy paste the directory myself but just want to make sure I'm not missing some functionality.
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 was wondering about MC and hey can help to lag a game out. I set up an advanced class system so i don't have to use MC to simulate walls, all i use isthe x,y,width and height. Well anyway since i don't need MC anymore I was wondering if there is a way to attach Graphics instead of MC cause a Graphics file size is relatively small than that of a graphic, I think. If anyone could tell me thats true and show me a way to attach graphics that would be nice. I haven't tried it yet but maybe if I exported the graphic from the library imihgt be able to call its name, but it doesn't have an instance name so im stuck.
I have a tree with nodes , and a delete button , first user select the node and click this delete button , I want this node to be removed from the tree , Its not XML , every node in tree is of type Object
{label:'folder',children:[{label:'file1'}]}
I tried delete myTree.selectedItem (but compiler wont let me do it) also tried myTree.selectedItem = null (just unselects the item)and also how can I access reference to parent object of myTree.selectedItem ?
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]............
Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
I have a Flex Tree component in my app. I set the icons for open and close. BUT I can't find something about changing the default background-color from white to something different.
obviously there is no background-color setable in css...
I know flex is a client side technology, but our customers are asking us to e-mail them reports (i.e. graphic images) that look just like the flex graphics we show them on the desktop on a nightly basis.
I'm trying to use the tree component in conjunction with a php page I have that produces xml. But I am literally struggling so much its ridiculous*. My php page is printing out this:
I have created a tree with a custom treeitemrenderer where I have added a textinput box next to each label. My data provider is an ArrayCollection. When I enter value in the input box, I can see the value fine as I expand or collapse the tree using the disclousure arrow. There is a strange issue when I try to expand and collapse tree from the mxml page with a button click to expand and collapse tree using the following code.
The problem is as I expand or collapse tree, the values I entered in the input boxes appear to be moving.
For example, I have entered 15 in input box 1. When I expand and collapse tree, 15 moves to another input box, and moves to another, and then it moves back to where it was entered as I keep expanding and collapsing the tree. I am still learning Flex. I am not sure what is happening, it is something to do with arraycollection.
I just read a comment at FlexExamples: One thing to note about the tree is that it is really just a list in which items are displayed. What that means is, you can't really drop somthing "into" folder unless the folder is open. Even in that case the user experience isn't quite right. So try moving everything out of one of the folders and then collapse that empty folder. If you drop something "on" the folder, it actually winds up between the target folder and the one below or above. This is indicated by the black line showing up as you move the mouse over the folders. If you "open" the folder (the only way to tell it is open is by the arrow) and then try it, you end up with an additional drop zone that is basically the bottom half of the opened, empty folder. This is also indicated by the black lines position.
It would be better if the middle section of any item could always be the drop zone for "add to this folder" and the top and bottom edges could be for dropping above or below respectively.I've just come to the same problem. Has somebody already managed this problem? In my case, I have dragMoveEnabled in the tree and offer the ability of dragging the tree items. But it is impossible to drag an item into another item that is empty. You can only drop the dragged item above or underneath an empty item.
How can I use multiple item renderers in mx:Tree depending on item's depth/level in tree?For example. For the first level items I want to use label with button and for second level items combobox
i have a tree of nodes that i dont want some type of nodes to appear in the tree, i can check the data on tree item renderer for each specific node type, so i have one type that i dont want it to be shown as tree node, like it doesn't exist.
where the component before / represents parent and the children of the corresponding parent are separated by , Can anyone provide me the logic to create a array collection for this hierarchy to set as dataprovider to my tree.
