I have a List with an item renderer and would like to enable drag-and-drop onto the items in the list, rather than adding the data to the list. Is it possible to find the item that is being hovered over when dragging?

View 1 RepliesI have set up some lists (<mx:List>) in Flex... I have drag and drop working fine, in that I can move elements easily from list to list. For some reason though, my DragInitiator and the currentTarget of my event are the same... even though I am obviously moving from list to list... Does anyone have an example of a function that I can call on my "dragComplete" event that will tell me the current target which will give me the id of the List object I am dropping on?This is my current function which is always returning true...

I am trying to implement a drag and drop function between a list control and a columnchart in Flex3. List items should, when dragged and dropped on the chart, be displayed raphically in the columnchart.Alas, dropping the listitems on the chart does not seem to result in a proper graph.Here my code till so far with regard to the drop part:
private function doDragDrop(event:DragEvent):void{
var ds:DragSource = event.dragSource;
var dropTarget:ChartBase=ChartBase(event.currentTarget);

I just started using Flash Builder 4 (yesterday infact).
I have two lists and a canvas. When dropping a list item onto the canvas, i want to trace what item it is (the label and data) and which list it came from. From there, i want to add an image to the canvas according to the dropped item.
Here's my current code
private function componentDragEnterHandler(event:DragEvent):void {
DragManager.acceptDragDrop(Canvas(event.currentTarget));
DragManager.showFeedback( DragManager.COPY );

I'm using drag and drop on a DataGrid to reorder items. However, when the user holds down Ctrl he can initiate a drag Copy operation. How can I disable copying altogether? (not just cancel the drop, but also prevent Ctrl + drag from showing the (+) icon)

1. If i select one and drop it to the next list, then i select two and drop. the value one must be replaced by two.
2. When i click on submit i need to get what value i have in the list.
3. I need to check whether its right or wrong.
I'm creating a drag and drop game for grades K-2 and two of my pieces stick to the mouse when clicked. I'm not sure what the problem is as I've used the same code for all of my pieces. The pants1_mc and the glasses_mc are the problems.
View 3 RepliesI'm dragging from a TileList to a custom component. I want to know what is being dragged before I accept it. How do I set the "format" that is used for "event.dragSource.formats" in the DragEvent?
Edit for clarification: When you set "dragEnabled=true" on the TileList, it takes care of the drag source stuff, but it uses "items" as the format for the DragEvent. I'm looking for a way to have the TileList use the correct format.

I am trying to create a quiz in Adobe Flash CS3 using Drag and Drop Feature. I have created similar Drag items and I want to drag the item and place it into any target. For Ex. I want Drag1, Drag2, Drag3, Drag4, Drag5 should go to any target from Target1, Target2, Target3, Target4, Target5. The objects on Drag1 through Drag5 is similar like I am working on number system. So I want the Drag boxes to go to any place values into the target boxes. But the drag and target instance names should be unique and should be mentioned in the component inspector also.

View 2 RepliesI am making a horizontal list that I want to be able to drag each item around to reorder the list. When one clip is dragged over another I want the one under it to move left or right to fill in the empty space left by the clip being dragged. I cannot seem to figure out how to tell which movieclip is touching or "under" the movieclip currently being dragged around. It seems that the hitTestObject method need explicity instance names to work. In summary, I want to know the instance name of any display object that the dragging moveclip touches.
View 1 RepliesI basically want to be able to drag any item out of that list, and when doing so, have it that item automatically go to the bottom, and have the remaining items scroll up. I can handle the drag and drop part of it, but I'm confused on how I could get the remaining column of items to dynamically move up depending on which item is taken out. I'm thinking maybe along the lines of an array? And I also suppose each item will have to be loaded in.
View 5 RepliesBecause of screen size, I must ensure we're only displaying necessary data to the user.I have a drop down box that contains only 5 items and I would like that when an item is selected, it doesn't appear in the drop down box (since technically it's showing twice, once at the top as the selected item and once in the list). how I would achieve this? I tried using a custom CellRender and overriding the "set selected" function to call this.visible = false if selected is true, but that simply hides the item but does not remove it from the layout of the drop down list.
View 1 RepliesI'm looking for a way to drag names from a scrollable list and drop them into another area.From what I've read, it doesn't seem like I can use the List component if I want to achieve this, but I'm having trouble thinking of a way.Basically, I'm going to have a input text box that will be used to be populate the list. Then I would like the ability to drag the names from the list to a blank area.I was able to get it working with the input text box to populate the list, it was just the dragging part that caused me trouble.
View 12 RepliesI have a DataGrid that contains data linked to a server. When I select mutliple items from the grid (using shift-select) and drag some items out from the DataGrid to another component, the array of items being dragged over appears to be in a completely arbitrary sort-order, and are not in the sort -order f the DataGrid as I'd expect.
Therefore, wwhen i drop them on the target (which is unsorted), their order doesnt match that of the DataGrid... what am I doing wrong and how can i fix this?
I'm getting the array using:
var dragItems:Array = event.dragSource.dataForFormat("items") as Array;
Is this the wrong data source on dragSource to look at?
I should mention that the drop target is a nonlist control, and that i am using a custom drop handler...
I have a drag & drop activity where 3 of the drags can go into 1 of 3 possible dropzones and be counted as correct. On clicking 'Submit', if only some are placed correctly, there's a 'Show me' option - this is the bit I can't do:if some of those with more than 1 possible answer are correct, I don't know how to check which dropzones are free to place the remainder in. My code for the first bit, checking the hitTest is ok:
for (var i:Number = 0; i<aLabels.length; i++) {
//3 drag items have 3 poss dropzones:
for (var t:Number = 0; t<aNewCorrectDZ[i].length; t++) {
//IF ITEM IS DROPPED ON ANY DROPZONE:

I'm having a problem with my dragOver function.The point of my project is that can drag the items that are on the table to the little bag (this is a button) on the left bottom of the screen.The thing is that the dragging works but when I perform a hitTest the item is supposed to dissapear, but it doesn't....
View 3 RepliesI'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;

I have two spark lists,backed up by Array Collections, both of which accept drag & drop either to move objects between them or to reorder within the lists. I have a method which is called on drop which resets some properties of the object to 0, this works as expected...
protected function list_dragDropHandler(event:DragEvent):void
{
if(event.action != DragManager.NONE)

What I would like to do is only call this method only when the objects are moved to another list, currently it is called when I reorder within the same list too
I'm creating an application where the user can select an object from a list of objects, and then put it on the main window.
I want to have the list of objects presented like in the web app : [URL]

How is it possible to do this, having a list of objects?
I'm using a Spark List with a TextInput in the ItemRenderer, with ability for the user to reorder the list rows by drag'n'dropping them. This is how I declared the list :
<s:List id="list" left="245" top="119" width="667" height="433"
dragDrop="insertItem(event)" dragEnabled="true"
dragEnter="acceptDrop(event)"
dragComplete="finalizeDragAndMove(event)"
dragMoveEnabled="true" dropEnabled="true" focusAlpha="0"
skinClass="components.DataList_Campaign"
hasFocusableChildren="true" />
Everything works fine, except that it's impossible to select the text in the TextInput with the mouse, instead it's dragging the row...How can I set the TextInput to have priority over drag'n'drop ?
while i using drag & drop from listbox1 to listbox2 ,how can i get all the items of listbox2 in flex
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.
I have two spark lists and want to drag items from one list to the other. When im dragging an item and over the other list item, i want the target item to change the background coloer.Basically instead of showing the black line indicating that I will drop between elements, I want to see the target item highlight.
View 1 RepliesI have a list of objects containing an icon, a label, and a tooltip. I want to show only the icon and the label. The tooltips should be visible on mouse over an item.

When would you want to use removeAll() vs just new ArrayCollection when you want to clear an array collection. Remove all iterates though each item in the list. I can't see a case when I would want to use it.
