[code]I want a tree in this structure, having line between the nodes, also, instead of Open and Close Folders, I have added my own graphic there with label. I did by extending TreeItemRenderer Class. Now, I if iam dragging and dropping a child node ex:label5, and try i drop it above label1 here, it is getting dropped there. i.e.,it is becoming like.[code]
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 2 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 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. How can i force it to hide this black underline and highlight leaf-element to which i wanna drop my stuff.

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)

How can i implement drag drop functionality in Component 1 Flex grid. Also the grid should allow some functionalities related to dragged data like Allow deletion of dragged data in cells of Grid.Dragged item remains in original cell as well and in the cell where it is dragged to.If the original item is deleted, the dragged item also gets deleted.Grid should not allow data to be duplicated in same column.how is it possible in flex grid. It is a windows based application. So if any possibility of doing the same using windows application basic functionality.
View 1 Repliesi am designing a program using drag and drop functionality.i created three movie clips i.e circle_mc ,square_mc and triangle_mc.here circle is source and square is target if "circle_mc" is dragged and dropped on the "square_mc" then the "triangle_mc" should rotate 90degrees(clock wise). and if the "circle_mc" is removed from "square_mc" then the triangle should rotate 90degrees(anti clock wise).

Everything seems to work correctly locally, until I upload it to the test server. The SWF will connect to the database, but it won't load the images, and the drag and drop functionality messed up.
View 2 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.
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'd like to implement a custom drag on an AdvancedDataGrid tree structure, which only allows the drag on the branches (not leaves).I'm having much difficultly with this, trying to use the MouseDown event, but not having luck! I think I've got the mousedown able to figure out if the item is a branch of leaf. Any help on how to perform the custom drag with an advanceddatagrid?? [code]

View 2 RepliesI'm doing an application in flex where I draw different sprites inside a canvas. Depending of the dimensions, scrollbars can be appear. I would like to move the "image" with the movement of the mouse as you can see at the Adobe Reader when you are reading a document with zoom (hand mouse icon). In this way, you dont have to touch the scrollbar.I'm start trying with drag and drop properties of the canvas, setting the position of the scrollbar according with the movement of the mouse but that is not as I expect.
View 2 RepliesI am dragging item from a datagrid and while dragging I could see all of the columns in the selected record, being getting dragged.

View 1 RepliesI am building a flex project involving drag+drop of fxg graphics. My graphic is instantiated as below:
<graphics:arrow2 id="object" mouseMove="mouseMoveHandler(event);" />
I get an error: "Call to a possibly undefined method Graphic."
This works if I change my drag-object to Image and replace the 'Graphic' below with 'Image'. What should I use to be able to reference the fxg graphic in the drag-drop? My drag drop functionality is as follows
private function mouseMoveHandler(event:MouseEvent):void {
var dragInitiator:Graphic = Graphic(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData(dragInitiator,"gph");
DragManager.doDrag(dragInitiator, ds, event);

View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
How do I determine which Flex AdvancedDataGrid cell - row and column index - I've just dropped onto? calculateDropIndex seems to give me the row, but how do I get the column?

View 1 RepliesI'm trying to drag an item from a datagrid and drop it onto a UIComponet. Basically I just want the UIComponent to know that something has been dropped onto it and allow it to access the data of the dropped item.
I thought just listening for the drop event would do it but it seems not.
I found lots of documentation on dragging from one IList to another but nothing for this.

I need to detect when a user d-b-n-d an object into a sprite. I'm adding the 3 event listeners I need, but only one of them works:

container.addEventListener( DragEvent.DRAG_DROP, dragDropHandler);

View 1 RepliesI'm developing an application that will randomize a list of words, and display them to the user. The user will then be able to drag the box containing each word over a Cartesian plane, and drop it anywhere they like. They will also be able to link various words together on the same plane. Once a user has completed these tasks, I want to update a database with that user's data - the coordinates of each word, as well as any parent words that may exist for each word. I started developing the application in Flex, but I'm running into problems integrating the data manipulation. It might just be me, but I find the way Flex is structured to be very counter-intuitive. I'm playing around with shifting the project over to perhaps a JQuery build. I'm proficient in neither JQuery nor Flex, however, and I'm not sure which one will be easier to pick up and develop a working prototype with.
