How do I prevent a user from dropping an item outsider a folder? My dataProvider is only 1-level deep.It seems that with a DragEvent handler or DragDrop handler I can find the data of the item I'm dragging, but not where I'm dropping ( so I can prevent it ).
View 1 RepliesI have a flex tree with dragMoveEnabled = true. I want to find out, when an item is dragged into itself or it's children. I'd like to use DragManager.showFeedback(DragManager.NONE) in the tree's onDragOver handler, but can't find out how get this to work. I'm using an ArrayCollection of nested objects as dataSource for the tree.
View 2 RepliesI have a tree in Flex Application and one of the items is selected.
When a user clicks another item, I would like to make a check and possibly prevent the change of selection.
I tried catching click event and calling stopPropagation, and also itemClick with stopPropogation but both do not prevent selectedItem from changing.[code]...

I placed my AMFPHP folder inside my htmltemplate project folder, but now everytime i build it wants to 'refresh' the folder which takes forever. Is there a way to set it so that folder does not refresh each time? I put the AMFPHP folder in there so I can have a unique copy for my debug builds and leave the production build one alone.
View 1 RepliesI 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.

View 1 RepliesI have a tree (in Flex 3.5), and I want to use the drag & drop functionality, but I want to let the user only move nodes, not copy them. I tried listening for the dragOver event and change the drag event's action property if it indicates a copy operation, and also listening for the keyDown event and changing the feedback using the DragManager if the pressed key was ctrl, but to no avail.

View 5 RepliesI am currently working with a hierarchical tree structure in AS3/Flex, and want to enable drag and drop capabilities under certain conditions: Only parent/top level nodes can be moved Parent/top level nodes must remain at this level; they can not be moved to child nodes of other parent nodes Using the dragEnter event of the tree, I am able to handle condition 1 easily.

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?
View 1 Replieshow would you prevent dragging for some items of your List or DataGrid?
Let's say I had a list with two items: 'Tom' and 'Jerry'. Only 'Tom' should be dragable, not 'Jerry'.
Ideally I had a 'isDragEnabled(item:Object):Boolean' function, which is being queried by the drag source.
My difficulties start with the fact that the 'dragStart' event handler has a null value for the dragSource, so right from the start I find it hard to find out what the drag-start is about..
PS There have been a few discussions on preventing or canceling a drop, but I haven't seen much about preventing the drag start, hence this question.
I have an AdvancedDataGrid with editable parameter to "true". My problem is that after a successfull drag & drop, the item is being edited and I don't want this to happen. I tried to create a custom advancedDataGrid with this:

i have TileList from which i'm dragging some stuff(image) to Tree (something like dragging sounds into playlist in iTunes), but when i can drop this stuff, i see only underline, this mean i can drop it only under or above some leaf-element in that Tree.

View 1 RepliesSo there's been a new "feature" in the flash player since version 10.1, which reduces the player's framerate to 2 fps when the application window is out of view. This is good news for performance, but it can break some functionality, such as the Timer class.
I have an application which uses a Timer to display a countdown. Given the nature of the application, it is required for the Timer to complete its countdown even if the user is not there to see it. Imagine that you need to give the user only 10 seconds to perform a task. If the user minimizes the window halfway through the counter, they can take as much time as they want and still have 5 seconds left when they return to the window. This apparently can not be avoided with the newer flash players.
In Air applications there is the backgroundFrameRate property which can be set to prevent this behavior, but this is part of the WindowedApplication class, so it seems that it is not available in a web application. Does anyone know a way to keep a constant frame rate even when the window is not visible?

I have a tree control with a custom item renderer. The item renderer has different states that should be set while an item is being dragged over the item renderer. I understand from reading this post [URL] that the 'right way' to do this is to override the 'getCurrentState' method and append some text. I do that.
Now in my tree control I handle the drag over event and get a reference to the itemrenderer that is being dragged over and I set the boolean 'dragOver' property to true. Now I just need to force my itemRenderer to redraw. I can't figure that out. A workaround, is to just set the currentState of the itemRenderer.
how can I force my itemRenderer to refresh? (and I've tried calling validateNow, invalideDisplayList/Properties/Size, to no avail)

I wish while i am draging and moving arround TitleWindow instance and a specific event occure to simulate drop of the window, and not further moving been possible for a few seconds.It is very unusual question but it will be more than handy each point to a solutionP.S: The whole idea is as follow : When i am draging a TitleWindo instace with the mouse, and if the TitleWindow hit the border of it's parent container then to drop the TitleWindow, and not further moving is possible (simulating release mouse button). If i wish to move it again, then i should click the TitleWindow title again and grag it.

View 2 Repliesit is possible using Action Script 3.0 to allow a user to drop in videos / manipulate a text file to add or change videos/ text that feed to a media player, without doing it directly through the flash studio actions page. Ideally I would like to have a folder with the swf/fla file, all the video files, and perhaps a text file that alowed the user to manipulate the text of the video i.e. title/description Would it be easier to instead give that user a youtube like solution where they simply had the ability to upload/describe videos, through the webserver, rather than do it through a pc?

View 4 RepliesI'm finding that in flash (10.x at least) and ie (7, 8, 9) that if I try to load an image url that contains escaped utf-8 characters (p%C3%83%C2%A5) that the characters get decoded before it makes the url request, even if I double or triple encode them. Is there any way to prevent this so the url (with escapes) the way I want it is actually what is requested?
The problem its causing is we give a http status of 301 on utf-8 decoded url requests to the encoded url which flash then tries to request (but ie decodes it again) and I get stuck in an infinite loop because of the 301 + ie auto-decoding.
EDIT, adding code sample:
var url:URLRequest = new URLRequest('http://mydomain.com/p%C3%A5.jpg');
var loader:Loader = new Loader();
loader.load(url);
Now I want the request to go over the line as [URL] (and it does in other browsers), but in IE it goes over the line as [URL]
EDIT: replacing % with %25 (double encoding the %) but that didn't work, it just caused this request to go over the wire: [URL]

I want to have a tree node renderer which act as follow :Clicking on it change the node height.I have tried as follow : to create a custom class derived from UIComponentand then insert it inside the tree node renderer, but because of some reason it doesn't work as I expected.Here's the code :

I have a canvas onto which I draw shapes like rectangle etc. When I move the shape using my custom mouse down/mouse move handler, the shape can go outside the parent bounds.
I am checking if the child is outside the parent's bound to snap it back:
var bounds:Rectangle = this.getBounds(this.parent);
var p:Point;
if (bounds.x <0) {
[Code]...
The snapInside method gets called when I go outside the left or top boundary. But when the child is dragged outside the right or bottom boundary, I find Flex/Flash runtime automatically expands the parent's height and width. So say the parent size was initially 800x600, if child Y bounds exceed 800 by say 20 pixel, I find the this.parent.height automatically resized by flex to 820!!
How do I prevent the parent from resizing when child goes outside the original bounds of the parent ?
