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 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.
I created an item renderer for a advanced datagrid and decided to put color on some of the cells. However the result comes with a vertical gap between the colored cell ( you can notice a big gap of white lines between the red cells on the screenshot)
View 2 Repliessimple (?) question: what's the easiest way to programmatically change the style of an ADG cell most recently clicked by the user? Important note: I'm assuming cells not to editable and the selection mode to be singleRow, i.e. the specific cell needs to render differently from the standard highlight that comes with being part of the selected line.
View 1 RepliesI've two problems, the second of which is only an issue because it's a possible way to fix the first! I'm developing a Flex 4.1 application, using a Spark theme: I can't change these; Halo isn't an option. It's providing the facility to fill multiple-selected cells of an AdvancedDataGrid with a single character, from a single keypress. So the user selects their cells using the Shift key, hits H (for example) and sees all the cells update with H, without using an itemEditor but via grid keyDown events instead. Then they click somewhere else and the selection should clear.
However the visible selection isn't fully cleared and the newly coloured cells won't all change from their selected colour. Underneath I can verify that the selection has cleared: mygrid.selectedCells is empty. All behaviour afterwards points to some kind of display glitch with the grid: The cells aren't selected any more but they look like they are.

I'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 RepliesIs there any way to detect if AdvancedDataGrid itemClick event is actually caused by the user dragging? I'd like to take action on click, but ignore drag.

View 2 RepliesI have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.

My Problem: I want to know the new node where the leaf was dropped. Actually i would have expected that in the event there is a property like dropParent. This is not the case.
I am trying to do a flex drag and drop. It is very similar to this first example.url....The problem is that event.currentTarget.mouseX,mouseY is showing the position where I put the mouse down rather than the position where I had finished dragging.

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. However I only want to show one column (maybe name or id of the record)? Is there a way to achieve this? Also, could I show an icon or image instead of the record while dragging.
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);

We need a capability by which we can drag and drop swc components in our Flex Application.

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.
<mx:UIComponent xmlns:mx="http://www.adobe.com/2006/mxml"
initialize="init(event)" dragDrop="itemDropped(event)">
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.
View 1 RepliesI am trying to build a visual simple electric circuitry model. Towards thata) I am looking to build a drag & drop functionality, whereby I have items (wires, resistors, battery) that can be dragged and dropped on screen where I have a 10 x10 grid- the dropped items will take line positions on the grid based on where they fall.Should I do this using the mouseX, mouseY and connect them to grid points they fall closest to? The typical drag and drop examples I have seen, don't concern themselves with exact position in destination- which is obviously important here
View 1 RepliesWhen I enter with a dragged item into datagrid, a bold line appears over the active row of the datagrid (which is fine to show the active row), but the problem is that even after I drop the item into datagrid, that line remains there. It goes only if I enter with a new item (in which case a new line comes to the respective row again).
I am using custom handler for dragdrop event for this datagrid.
I am trying to drag and drop an object across the SkinnableContainer- am coming across a very strange issue
The drop occurs only at a few places- elsewhere it just shows the "X" sign and on dropping there, reverts to original position. I have used very standard commands... from function 2 to function 3, the call occurs very rarely as seen in trace statements- any guidance on why this happens?
I added the following code to SkinnableContainer: dragEnter="dragEnterHandler(event);" dragDrop="dragDropHandler(event);
(1):
private function mouseMoveHandler(event:MouseEvent):void
{
var dragInitiator:Image = Image(event.currentTarget);
var ds:DragSource = new DragSource();

In order to improve user experience we want the ability to have an animated movieclip of a turning wheel- and have the ability to drag and drop it anywhere on a defined area
We have built the rotating wheel as a swc file.
How do we do the drag+drop. Examples that I have seen, cater to only dropping of images.
I need a way to drag and drop an image from a container to another. I have tried a few different ways but I guess the drag & drop thing is still eluding me. Anyway, here's what I am trying to do, A container will contains a few bitmap/vector image (what's the best way for this? Tile Group? Or?) and then I want to be able to drag any of the image onto another larger Image inside of a Panel. Just like dragging shapes in Photoshop. No code here, as I am completely lost on how to go about it. I found a few tip/tutorial here and there but none which I could understand easily or adapt to my need.
Edit 1 : Got so far till now :
public function beginDrag( mouseEvent:MouseEvent ):void
{

I 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 have a Flex panel, in InDesign, from which I drag an URL. If I drop this URL on a text editor or a web browser, it works. But when I try to drop it on my InDesign document, it's a little bit harder.I have implemented a subclass of CDragDropTargetFlavorHelper. The drop works perfectly on Windows. But on mac, I have problems in the method CouldAcceptTypes :
DragDrop::TargetResponse AutocatDNDCustomFlavorHelper::CouldAcceptTypes(const DragDropTarget* target, DataObjectIterator* dataIter, const IDragDropSource* fromSource, const IDragDropController* controller) const
{
if (0 != dataIter && 0 != target)
[code]....
The problem is the IMPDataObject I get is nil. There is no item in the controller. However, there were items in the CouldAcceptTypes method, in the DataObjectIterator. So, where are my items ?I tried using a custom CDataExchangeHandlerFor, but could not really understand what its usage was for. It didn't work anyway.
