I 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 1 RepliesI think there is a simple solution to this question, just not simple enough for me to find it.Question:How do you constrain a TitleWindow in Flex 3 from being dragged off the screen/stage? Is there a way to restrict the TitleWindow to the viewing area? Example: Let's say I have an application that take 100% of the screen. Next, I create a TitleWindow via the PopUpManager. I can then proceed to click and hold (drag) that window off the screen, then release the mouse button. That window is now lost off-screen somewhere. Is there a way to keep the window from being dragged beyond the viewing area?
View 6 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]...
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 was in situation that tree is re-using my custom item-renderer.. is there any method or way around we can stop tree to reuse.. and always create a new item-renderer for new item..
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 array of items that should be selected in my tree control. As you can see from my code below, I bind this array to the selectedIndices property of the tree. The selected Items are not properly selecting in tree(selecting some other items and always root is selected).Flex seems to "ignore" my items (selects some other indices).
My XMLList:-
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
<fx:XMLList id="XMLList">
<node><node name="max">
[Code] .....
I'm trying to modifty the Flex Tree control to allow a user to select multiple items by just clicking each of the desired elements (ie I don't want them to have to press Ctrl or Shift). If the user clicks a selected item a 2nd time, it will deselect it.
View 2 RepliesI have the AS to move pictures around (like a jigsaw puzzle i guess), im just struggling with setting boundaries so that the pieces cannot be dragged off the stage...
Im presuming setting the boundaries is a matter of adding X and Y values or similar.
I have made a flash application and in this flash application I have included a jigsaw puzzle. The application is wrote on one timeline and certain frames are used as different pages within the application.
The problem is once the jigsaw drag and drop are moved the pieces are displayed on all frames instead of just the one jigsaw puzzle frame I created.
How can I make these drag and drop items not be shown on the other frames?[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?

View 1 RepliesWhat's the easiest way to prevent what I call preloader flicker. What I mean is the preloader works fine on first load but then once the external swfs have been cached the preloader still displays for just for a split second but doesn't have time to animate and it just looks a bit ugly. I ideally just want the preloader to appear on first load or force it to animate.
View 14 RepliesIs there a way to group context menu items into a tree like structure?Like the Quality in built in menu.You can test it on any flash that has the built in items enabled.Right Click -> Quality -> Low.Can you do the same with custom items?For example:Right Click -> Custom Options -> Option 1
View 5 RepliesI'm in the middle of creating a tree menu that needs to expand/collapse when items are selected. I'm drawing all my info from a DB via sendAndLoad. I'm having alot of problems getting the "math" right for the menu tho. If you look at the attached movies (play main.swf, which loads 1.swf) and click on Villas, you'll see what I mean. I need to have each of these items expand/collapse when they are clicked on. There will never be more then one layer under each main country, so it only has to do the expand/collapse when clicking a country.
View 2 RepliesOn the attached exercise, is it possible to stop further items being dragged onto a target when the target box is full?
View 1 RepliesI would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

View 2 RepliesI'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
I am using PopupManager in FB4 to display a custom dialog.
popwin = new TitleWindow();
popwin.addElement(myCustomDialog);
PopUpManager.addPopUp(popwin,this,false);
PopUpManager.centerPopUp(popwin);
It's possible to drag the popped up TitleWindow and let go of it when its gray title bar lies outside the bounds of the Flex app rectangle,and then the popup cannot be grabbed again.It's also possible to drag the TitleWindow downwards so it becomes completely invisible below the bottom edge of the Flex app rectangle.When the Flex app bounds are less than the full browser window,and the user is working quickly, this chances of this happening increase.Is there a simple setting that will keep this from happening, or must the programmer intercept the behavior during the drag operation?
I have a list that accepts drops. When an item is dropped (DragEvent.DRAG_DROP) I need to collect the data that is dropped, however I have found nothing in the event thatdo so, event.dragInitiator.selectedItems would work but gives me an error.
View 1 RepliesI 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?
Code:
stop();
MovieClip(lion_mov).stop();
//video Mouse Click[code].....
Frame 3 just includes all the mouse clicks for the tree.

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:

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.

If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...
