Drag and Drop - Drag Image

I'm using the Flex DragManager in an AdvancedDataGrid with
HierarchicalData to allow the user to drag and drop tree nodes to
re-order them. It is working fine. The problem I am having is with
the drag image. The drag image does not always show up. It seems
like it will appear for one drag and drop. Then if I try to drag
another tree node I do not get the drag image there is just a line
to show I'm dragging something.
When I say drag image I mean the faded image of the text of
the tree node which appears as I drag the tree node.
I am using the following properties on the AdvancedDataGrid
to enable drag and drop:
dragEnabled="true" dropEnabled="true" dragMoveEnabled="true"
Now if set dragMoveEnabled="false" then I do get a drag image
everytime. But I need move the tree nodes around not copy them so I
need dragMoveEnabled="true".
Thank you

When i drag and drop an image on my site. it gives the following error. "Unable to access local files due to browser security settings. To overcome this, follo"

I am using the firefox version 17 and when i drag and drop an image on my website. It gives me the following error.
Unable to access local files due to browser security settings. To overcome this, follow these steps: (1) Enter "about:config" in the URL field; (2) Right click and select New->Boolean; (3) Enter "signed.applets.codebase_principal_support" (without the quotes) as a new preference name; (4) Click OK and try loading the file again. Or go to the homepage for a link to the tutorial on how to do it.
I have completed the above steps and it is still showing the same error message. Any help would be highly appreciated.
Thanks.

Thanks kumars ,
I have a specific drag and drop area on our website. This works fine for all earlier releases of Firefox after these security settings
"(1) Enter "about:config" in the URL field; (2) Right click and select New->Boolean; (3) Enter "signed.applets.codebase_principal_support" (without the quotes) as a new preference name; (4) Click OK and try loading the file again."
Bust these settings not work for me in Firefox 17.
Yes the drag and drop functionality is java script based and i am not using any script blocker addons.

Which Listener I should use if I drag and Drop an image/icon into a JPanel?

Dar Friends:
Happy new year.
I try to drag and Drop an image/icon into a JPanel, and hope I can immediately detect it after DND,
Which Listener I should use in this JPanel if I drag and Drop an image/icon into a JPanel??
Thanks

Thank camickr .
I can dnd an image into a JPanel called JPanelOld already, I hope to use another JPanel or JTree to listen to any Dropped Image in JPanelOld later on so I can take some action in another JPanel or JTree.
so what kind of Listener I should use for my purpose??
where to add this Listeners??
Happy New Year.

BUG - Drag and drop an image, only working at the 2nd try

I use the last version of JDeveloper : 11g R1 : 11.1.1.2.0
I try to drag and drop an image in a facet of a panelsplitter.
Once the page is loaded, the first time I try to drag the image, it does not work : the image does not follow the mouse.
When I try to drag the image again, then it works : the image follow the mouse
So I don't think it's related to the destination/target.
I feel it's so simple, since it just requires to add <af:componentDragSource/> inside <af:image/>
that if it does not work, it can only be a bug in the functionality offered by ADF ...
Or maybe there is something wrong with the generation of the page ?
I get this message in blue in the "running log of WebLogic" :
<FormRenderer><setupEncodingContext> Multiple forms detected on viewId: /myPage.jspx. Rich client currently has some limitations in dealing with multiple forms.
Please note that I use jsp:include inside f:subview to include fragments (.jsff) so that the source and the destination are not in the same file, the source in a .jsff while the destination is on the main .jspx
The code related to the drag and drop :
<af:form id="form">
<af:panelSplitter orientation="vertical" splitterPosition="70" id="psHeader" clientComponent="true">
<af:panelAccordion id="paPref" discloseNone="true" styleClass="fullSize">

<af:panelGroupLayout id="pglTemp" layout="scroll">
<af:panelList id="plTemp" rows="2">
<af:image id="imTemp2up" source="/images/anImage.jpg" inlineStyle="" shortDesc="...">
<af:componentDragSource/>
</af:image>
<f:facet name="second">
<af:dropTarget dropListener="#{dropHandler.handleComponentMove}" actions="MOVE">
<af:dataFlavor flavorClass="javax.faces.component.UIComponent"/>
</af:dropTarget>
Any idea ?
Thanks in advance,
JP

Hi,
no bug that I can detect here as it works for me with the same setup. How likely is it that the image is too small so that you don't grab it probably the first time?

Is there any view where I can drag-and-drop an image to another app?

I'm new to LR3.4.   I'm building books using Luminix PhotoFusion and used to be able to drag-and-drop images directly from PSE5 into Luminix.   With PSE8, that capability was lost and I had to bring up the file properties, go to the containing folder, and drag-and-drop from there.   This greatly slows down the process.   I don't want to export the images because then I have multiple copies to maintain.
Does anyone have suggestions for a workflow for this?   I haven't looked into publishing yet but that also seems to replicate like to Flickr.
Thanks

I've tried drag-and-drop from the grid, filmstrip, etc.   I get the universal circle with a slash.... no go. I've tried dragging to WORD, PowerPoint, IrfanView, PhotoFusion, and all have the same result.
I'm running Win7 64-bit.

Can I drag and drop an image into Photoshop

hello, as a first time user ive using photoshop on a mac at school. i just downloaded photoshop on my pc. i cant insert my image onto photoshop. the way we do it in class is drag the image to the ps icon and it will open with the pic. please help and if theres anything i need to know please inform me also. thanks for all the help!!! ps im also learning how to use intuos tablet with it

Welcome to the forum. I don't own a mac, so I may not be as accurate as I would like.
It may require photoshop to already be running for the drag and drop to work. Try minimizing photoshop then drag and drop.

Ok I found the answer to your problem. If you download the tutorial they have the code there it's in one folder. I hope this helps.

Drag-and-drop for image stacks

I'd like to be able to drag and drop image stacks from one folder to the next. Currently, when I drag and drop it just grabs one of the images from the stack and leaves the others behind.
I can expand the stack and then drag and drop all of them, but the stack itself is lost--I have to go to the destination directory and re-stack the images.
Bart

I've discovered (and its nowhere in the documentation as far as I can see) that if you select the bottom slide in a stack .. ie the bottom left hand corner of the "reperesenation of the lower slides" you can drag and drop the stack(s) in to another folder.
Unfortunately they don't remain stacked ..Here's another vote for persistent stacks.

Drag and drop a image from html page into flex

how can i drag a image form the html page and drop it into
the flex application.

Hi,
There's no direct support for this. But you could implement
drag and drop the way you normally would in javascript. Except
here, on mouseUp over a div encapsulating the object or embed tag
(the flash object), you'll need to make a call into actionscript
from javascript indicating that a drag and drop happened.
For more info, see
how
to drag and drop using javascript and
actionscript
and javascript communication

Drag and drop an image over a JPanel (only change position on same JPanel)

Hi all,
there is JPanel added to a JDialog.
There is a BufferedImage on the JPanel: I need to let the image be dragged and dropped in another position over the same JPanel and read the new position's coordinates.
(Maybe the image has to be wrapped in a JComponent?)
Thanks in advance for any suggestions.
Ludovico

(Maybe the image has to be wrapped in a JComponent?)Just add the image to a JLabel and add the label to the panel.

Drag and Drop an image

Can anyone recommend me a good tutorial on how to drag and drop or even resize an image in a panel ?

I'm back.
I wrote a 2 classes appli that allow to move and resize images displayed in a panel.
The first class is the most interesting one. It describes an object which extends Rectangle and manage an Image. This class names TransformableImage extends Rectangle because we need to know the bounds of the rectangle, where the image is contained in, to allow mouse interactions through the panel.
The behavior we want is to change the kind of cursors according to the position of the mouse on the panel :
if the mouse is out of any images the cursor is the default one. If the cursor is on an image, it can be a move cursor in the center of the image or one of the resize cursors if the mouse is on the border of the image.
Here is the class :
import java.awt.*;
import javax.swing.*;
import java.awt.image.*;
public final class TransformableImage extends Rectangle {
     public static final int MOVE = 0;
     public static final int RESIZE_TOP = 10;
     public static final int RESIZE_BOTTOM = 20;
     public static final int RESIZE_RIGHT = 1;
     public static final int RESIZE_LEFT = 2;
     public static final int RESIZE_TOP_RIGHT_CORNER = 11;
     public static final int RESIZE_TOP_LEFT_CORNER = 12;
     public static final int RESIZE_BOTTOM_RIGHT_CORNER = 21;
     public static final int RESIZE_BOTTOM_LEFT_CORNER = 22;
     public static final int BORDER_THICKNESS = 5;
     public static final int MIN_THICKNESS = BORDER_THICKNESS*2;
     private static final Color borderColor = Color.black;
     private Image image;
     * Create an TransformableImage from the image file filename.
     * The TransformableImage bounds (inherited from the class Rectangle) are setted to the corresponding values.
     public TransformableImage(String filename) {
          ImageIcon ic = new ImageIcon(filename);
          image = ic.getImage();
          setBounds(0,0,ic.getIconWidth(), ic.getIconHeight());
     * Draw the image rescaled to fit the bounds.
     * A black rectangle is drawn around the image.
     public final void draw(Graphics2D g, ImageObserver observer) {
          Color oldColor = g.getColor();
          g.setColor(borderColor);
          g.drawImage(image, x, y, width, height, observer);
          g.draw(this);
          g.setColor(oldColor);
     * Return an int corresponding to the transformation available according to the mouse location on the image.
     * If the point p is in the border, with a thickness of BORDER_THICKNESS, around the image, the corresponding
     * transformation is returned (RESIZE_TOP, ..., RESIZE_BOTTOM_LEFT_CORNER).
     * If the point p is located in the center of the image (i.e. out of the border), the MOVE transformation is returned.
     * We allways suppose that p is contained in the image bounds.
     public final int getTransformation(Point p) {

}And now, we need to create the panel where we are going to draw the images and interact with them with the mouse. In fact we need a paintComponent method used to draw the images and a Mouse(Motion)Listener to manage the required mouse events.
We also have to create a method to set the convenient cursor according to tha position of the mouse over the images.
Here is the class :

     private static final Cursor NE_SW_RESIZE_CURSOR = new Cursor(Cursor.NE_RESIZE_CURSOR);
     public Vector images;
     * Create an ImagePanel with two images in.
     * A MouseHandler instance is added as mouse listener and mouse motion listener.
     public ImagePanel() {

          MouseHandler mh = new MouseHandler();

     final class MouseHandler extends MouseInputAdapter {
          private TransformableImage draggedImage;
          private int transformation;

Identify Drag and Drop Drag Source

I know this is not the way the Drag and Drop works, but I am wondering if there is a way to identify which drag source was dragged to the target.
My scenario:
I want to allow the user to drag a character from the waiting room to the registration desk, and to know which character was dragged, then I will use that information to ask appropriate questions to the user regarding registration, based on the character. So I will have numerous characters, all draggable to the same target.
I don't see any indication that Captivate gives me this information, that is, which drag source was just dragged to the target.
I know I could just ask the user to click on a character, but I want to do something a little more interesting.
Thanks.

Each drag action can be used to trigger an advanced action. You can use that action to populate a variable, perhaps with the name of the character. And based on that information you can achieve your goal.

I can't drag and drop an image into Photoshop CS5

I don't know what's going on. I've never had this problem before.
When I try to drag and image into photoshop I get the black circle with a black line through it
I took of the administrative settings also. I've tried everything, I've uninstalled it then reinstalled it. Nothing. Please help.

Well yes cleem any photoshop icon, or shortcut, whether its in your start menu, on you desktop....
careful: this is tricky, if you right click the photoshop icon on your windows 7 taskbar, a new menu opens, you'll have to right click again on the "Photoshop cc" icon, in order to access properties.
does this make it clear? did it work fine with you? let me know

Help me drag and drop my image please

my image is in JLbel
i want to MOVE image between JLabel (JPanel too) not COPY
like the chees game
but i look at the chess game source in "search"
it's use JLayer on JFrame
but i use only JFrame
can you give me sample
move image between JLabel
i think JLayer must have something differ from JFrame

but i look at the chess game source in "search" it's use JLayer on JFrameYes, thats one approach.
but i use only JFrame can you give me sample move image between JLabel And you where given the link to the Swing tutorial on using DnD that shows you how to do this.
So you have two working solutions. Choose the approach you want to use.
I hope you don't expect us to write the code!
