Actionscript 3 :: Flex Tree Droplocation Indicator Stuck
Jan 20, 2010
OK I've got a little more research on this done so I'm going to totally rephrase the question: I have two trees, I want to be able to drag items from one tree to the other. In the receiving tree I have some logic that allows or denys the drop. I am using the native cursor feedback Like this :
[Code]...
When the logic determines NONE it properly rejects the item except the drop position indicator sticks like in the screenshot. I know now that neither dragComplete, nor dragDrop are being fired in this situation, so I have no function to put code into that would clean that up. So how can I listen for this drag rejection? ScreenShot shows app After drop
I want to add an indicator on a tree node icon , meaning , for example like in eclipse when there is an error the icon get a special small indicator on the regular icon. how can i do that?
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 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 movie which is serving as a button.When you rollover the image, it grows, and stops.When you rollOut, it shrinks, and stops.This code works fine. The Problem:When you scroll the mouse over quickly, the animation get stuck and doesn't execute the rollOut code.This is most likely because the first rollOver action hasn't yet completed.Here's my code:
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 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...
The Scene "bar" (don't know official name), which is supposed to be directly above the Stage, does not appear on my version of CS4 Pro.It's visible on the computers at school, but it doesn't appear on my screen on my Mac.How do I make it appear?A search in the preferences yielded nothing.No tabs or little things to click around the stage area, either.This is not to be confused with the Scene palette from the top pulldown menu.NOT windows > other panels > scene.
Is there any way I can hide the focus indicator for everything in my document? Can't I just make some Focus Manager for the entire document and do hideFocus() from there?
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.
I am using mx:Tree (in Flex 4), and assigned a customised MXTreeItemRenderer for every items. As the TreeItemRenderer contains a list with tileLayout, which means the height of every row is variable. So I have to set the tree's "variableRowHeight to true. When I was testing the tree, everything went well. But when I was using the vertical scroller, I met some problems:
The scroll bar did not move to the position I want. When I was scrolling the content, the scroll bar sometimes scrolled to a unwanted position (e.g. the head of the tree). When there are more rows, the problem is more obvious.When I was scrolling the tree, the images were flicking all the time.
I have a Tree object in my Flex code. It's width is 100%, and it is contained by a Panel with width=200. I am using a custom itemrenderer that extends TreeItemRenderer.I need the text in each node to word wrap if it's too big (as happens often). I have triedlabel.wordWrap = true;
I just built a website entirely in Flash Catalyst CS5. After adding a few more states the file size got bigger and the loading time increased. On average, it takes about 10 seconds for the site to load on my connection. Till then all you get is a white page and the spark preloader shows up when you scroll down. All I want is a simple preloader with a percentage indicator, loading bar, and maybe my company logo.

I'm looking for a tutorial that shows you how to create a menu indicator from an mc.
Basically when you click a menu button I want an mc of a box to tween with easing to that button as an indicator as to what section the user is currently viewing.
Ive seen one awhile back but cannot seem to find the tutorial on it.
