Flex :: Dynamically Load Image For Drag And Drop?
Jun 27, 2010
I am implementing drag and drop from a DataGrid onto a List in a Flex 3 AIR application. I would like to have the drag image be a photo (jpg) referenced by a String field in the data grid item, named 'imagePath'. I'm having trouble getting the image to show up during dragging. I have triple checked that it is not because of an invalid path to the image. I have tried Image's source() and load() methods in every way I can think of. I am calling this method 'dragCurrentToList(event)' on a mouseDown event.[code]This works perfectly if I set the image source to the following bindable variable but I don't want to hardcode the image name.[code]

I would like to know how to set up the URLRequest to load an external image to a movie clip that is being used in a Drag and Drop event.I have successfully implemented the drag & drop code to my design but I would like to improve it by successfully loading external images to those objects that are being dragged around.I have both Var Load and starDrag codes. I am trying to figure out how to combine them.

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 TileList that's loaded with data from Flickr. The tilelist uses an imageRenderer to make a bunch of thumbnails. I'm trying to create a custom drag and drop function, but I want to get the image source of the tilelist mouseEvent target. Here's what the code looks like for the drag handler:

I'm looking to be able to pick up one of 36 movieclips on the stage, and drag it to a hotspot. If it lands on the hotspot, then it does something, otherwise it just gets dropped.
How do I dynamically change the "target_mc" to be whichever movieclip I select?
This code works fine, but that's because eventlistener is set-up explicitly for a given mc.
Code:
// sprites
import caurina.transitions.*;
var drag_mc:MovieClip = energy_sprites.play_wave;

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.

I have run into a drag and drop issue .I have an item that I would like to drag and drop. Seems simple enough, but I also want to make it that if the user drags the image off the screen, that it stops dragging and returns the image to the center of the screen. What happens now is that it continues dragging and sticks to the cursor if you release outside of the viewable area. The original piece has a lot of other things going on, so I ve created a simple piece with the AS in the timeline that shows only this particular issue.
Code:
var mrT:MC_mrT = new MC_mrT;
addChild(mrT);
mrT.x = stage.stageWidth*.5;[code].............

I'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.

I 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.

I 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);

I 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'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)">
