Implementing Drag and Drop

I would buy this product if the ajax features somehow
supported the implementaion of drag and drop in a way that was
simple to use.
I am dabbling in vb.net/asp.net and its version of ajax
tools. The support for drag and drop are not all that good at this
time.
I have even bought a book that had a chapter on it. It still
takes too much java hand written code to impliment it.
I also own dreamweaver MX. I use this product to do all my
web sites. They all are home stuff and fun stuff. My wife wants her
site to have the user be able to grab an object and drop it on a
specific location and have an event occur. In her case she wants an
animated GIF to fire.
I have turned to vb.net because i am a programmer and use
vb.net for application development. But!!! i am excited about DW
cs3. So my question is!!
Does DW CS3 Ajax tools provide a somewhat easy way to
impliment drag and drop without me having to write to much Java by
hand?
Thanx up front

Drag and Drop interfaces in javascript are nothing simple.
Don't expect any
magic wizards to help you with this.
There are a lot of AJAX/JS libraries. Many have DnD featuers,
but they'll
differ from library to library. you're going ot have to do a
lot of legwork
and takea look at them all.
I've used Scriptaculous in the past, but have found it
limiting. I'm going
to be looking at Jquery UI next.

Java is not involved. JAVASCRIPT is.
DW does not do .net, so you you're going to do .net, you
should look at
Visual Studio as your main development IDE.

Air mobile best way to implement drag and drop

Hi all,
I'm developing an application which allows people to drag and drop certain panels.
But the dragmanager isn't optimized for the air mobile platform.
What is the best way to implement drag and drop at the moment?
Write it all yourself or are their some utility classes that can help?

Implementing Drag and Drop Functionality

I'm implementing drag and drop a record from a table to another table.
I already referred below:
http://download.oracle.com/docs/cd/E15523_01/web.1111/b31973/af_dnd.htm#CIHDADFG
But I have a question.
In example 32-5, there is a source like following:
+// And now get the actual data from the dragged model.+
+// Note this won't work in a region.+
DnDDemoData dnDDemoData = (DnDDemoData)dragModel.getRowData();
In this case, 'DnDDemoData' type looks like each project's own suitable row type.
But I don't know what type is suitable in my project.
I use a two VOs for two tables.
So I think it's ViewRowImpl class type, but it's not.
How can I find suitable row type?

Hi Timo,
Could not understand what exactly need to have for this...
// And now get the actual data from the dragged model.
// Note this won't work in a region.
DnDDemoData dnDDemoData = (DnDDemoData)dragModel.getRowData();
Could you please elaborate on this!!!
Thanks,
Vin

How to implement Drag and Drop in trees

Hi,
I have two hierarchical tree in a form, i need to drag each nodes form one tree node and drop into another tree, how i possible. am using Forms 6i developer.

Drag-n-Drop is only available in Forms by extending Forms with a Java Bean. In order to use a Java Bean in your form, your form MUST be web deployed; if you are using traditional Client/Server with your Forms 6i then there is no way to implement Drag-n-Drop.
Take a look at: Drag 'n Drop - Oracle Forms PJC and Java Beans. This article was based on using Oracle Forms 9i so you might not be able to implement it in your Forms 6i app.

Implementing drag and drop across components with drag image...

Hey all,
Finally got the hang of drag and drop. Not too hard, but a little time consuming. I found an article showing how to capture and drag a BufferedImage within a JTree. When you click and drag a node, it creates a BufferedImage of the node on screen and "ghosts" it a bit, which has a very appealing effect.
However, when I try to drag this image to a JList component, it disappears. So I created the same affect in the JList component. Now you can drag the image from the tree to the list and vice versa. However, the problem is, the image does not "fly over" the borders of the two components (butted up against each other) with the mouse. The image seems to go under the borders, while the mouse floats above everything.
What I would like to do is be able to drag the image all over the application, perhaps even the desktop in the case of a SDI application. I want to be able to see this image drag from my Java app over the Windows Explorer folder, just like how you can do that with Windows Explorer, dragging an image of the selected node into any app that supports the drop. I know we can handle the "transfer" data from explorer and vice versa, but how to be able to keep an image with the mouse?
My best guess is somehow using the Glass pane, grabbing a ref to its BufferedImage (if that is even what is there), and drawing the dragged item in that pane. But, then, how will the image move over the desktop outside of the app, where a glass pane is not?
Is there a way to draw on top of anything, anywhere, but still be able to redraw the background as the image moves with the mouse? There are times where the image may be big, so I don't want to have to capture the underlying screen as an image covering the size of the drag image to restore it as the drag image moves around.
Thank you.

We know cursors support some degree of transparence because they have shapes other than blocks.
I've done some playing around with
Toolkit.getDefaultToolkit().createCustomCursor(....);The sad news is, it seems that as soon as a pixel's alpha value is greater than 0, it automatically becomes 100% opaque.
The best you can do, is to take your image, and divide it into a pixel-checkerboard, and set the alpha value of alternating pixels to 0.
e.g.
BufferedImage i = new BufferedImage(32, 32, BufferedImage.TYPE_INT_ARGB);
        int[] data = ((DataBufferInt)i.getRaster().getDataBuffer()).getData();
        boolean on = true;
        for (int z=0; z<data.length; z++)
            if (on)
                data[z] = 0xffffffff;
            else
                data[z] = 0x00000000;
            on = !on;
            if (z%32==0) on = !on;
        Cursor hazyWhite = Toolkit.getDefaultToolkit().createCustomCursor(i, new Point(0,0), "hw");

Implement Drag and drop functionality in my application

I want to drag image from one UIImageView to other UIImageView.
Is there any event handle to this drag and drop functionality.
Any one have different idea to handle this. than please reply.
Any coding idea related to this?

it is possible but u have to write some advance code to handle plz mention ur Forms version and other info
Forms 10g and above possible with Java beans
Forms 6i there is a demo in forms online help ........ Search DRAG
To enable drag and drop on an item:
1     Attach the PL/SQL library DRAG.PLL, which contains the Mouse package, to your module.
2     Create a WHEN-MOUSE-DOWN trigger on each item that can be dragged. From this trigger, call the Click routine from the Mouse package.
3     Create a WHEN-MOUSE-MOVE trigger on each item that can be dragged. From this trigger, call the Move routine from the Mouse package.
4     Create a WHEN-MOUSE-UP trigger on each item that can be dragged. In this trigger, write your application specific code.Baig

How to implement drag and drop functionality in a HTML5 webpage using touch events?

Hi all,
     I need to create a webpage having two parts.One part is having set of SVG images into it and other part is having canvas.I need to drag those image onto the canvas allowing same image for multiple times and those images on the canvas are movable inside the canvas only. This webpage is only used in iphone or ipad like touching devices so I need to handle touch events.
     There is already jQuery plugin for drag drop functionality but it is not supported for touch events.
It is only for desktop veriosns.So if you know about any jquery plugin let me know.
     So please help me to carry out this task.

I have tried using the same but still not working.
I have handled touch events like touchstart,touchend,touchmove.
But the problem is when I drag the image from upperbox onto canvas, the clone of that image is creating but the image which I dragged on canvas gets vanished.
I am creating clone because I want to add multiple images onto canvas.

Select All in a table does not work for Drag and Drop

Hi. I am using Jdeveloper 11.1.1.2 but have also reproduced in 11.1.1.3.
I am trying to implement drag and drop rows from one table to another. Everything works fine except when I do a Select All (ctrl-A) in a table, the table visually looks like all rows are selected, but when I try to click on one of the selected rows to drag to the other table, only the row I click on is dragged.
I tried setting Range Size -1, fetch mode to FETCH_ALL, content delivery to "immediate" but nothing works.
I even have reproduced not using a view object but just a List of beans with only 5 or 10 beans showing in the table.
Does anyone know how to get Select All to work for a Drag Source?
Thanks.
-Ed

Frank-
OK, thanks for looking into that. I also submitted this service request, which includes a simple sample app to demonstrate the problem:

Drag and Drop of cell content between 2 tables

Hi Guys,
Iam into implementing drag and drop of cell contents between 2 different tables,say Table1 and Table2.(Iam not dragging and dropping rows or cells,Just copying the content of one cell to another).
Have extended the java tutorial class "TableTransferHandler" and "StringTransferHandler" under http://java.sun.com/docs/books/tutorial/uiswing/examples/dnd/index.html#ExtendedDndDemo to satisfy my needs.
The drag is enabled for Table1 and table2 as follows.
jTable1.setDragEnabled(true);
jTable1.setTransferHandler(new TableTransferHandler());
jTable2.setDragEnabled(true);
jTable2.setTransferHandler(new TableTransferHandler());
Dont be taken aback with the code I have put.It just to show what I have done..
My questions are put at the end of the post..
//String Transfer Handler class.
public abstract class StringTransferHandler extends TransferHandler {
    protected abstract String exportString(JComponent c);
    protected abstract void importString(JComponent c, String str);
    protected abstract void cleanup(JComponent c, boolean remove);
    protected Transferable createTransferable(JComponent c) {
        return new StringSelection(exportString(c));
    public int getSourceActions(JComponent c) {
        return COPY_OR_MOVE;
    public boolean importData(JComponent c, Transferable t) {
        if (canImport(c, t.getTransferDataFlavors())) {
            try {
                String str = (String)t.getTransferData(DataFlavor.stringFlavor);
                importString(c, str);
                return true;
            } catch (UnsupportedFlavorException ufe) {
            } catch (IOException ioe) {
        return false;
    protected void exportDone(JComponent c, Transferable data, int action) {
        cleanup(c, action == MOVE);
    public boolean canImport(JComponent c, DataFlavor[] flavors) {
          JTable table = (JTable)c;
         int selColIndex = table.getSelectedColumn();
        for (int i = 0; i < flavors.length; i++) {
            if ((DataFlavor.stringFlavor.equals(flavors))&& (selColIndex !=0)) {
return true;
return false;
}//TableTransferHandler classpublic class TableTransferHandler extends StringTransferHandler {
private int[] rows = null;
private int addIndex = -1; //Location where items were added
private int addCount = 0; //Number of items added.
protected String exportString(JComponent c) {
JTable table = (JTable)c;
rows = table.getSelectedRows();
StringBuffer buff = new StringBuffer();
int selRowIndex = table.getSelectedRow();
int selColIndex = table.getSelectedColumn();
String val = table.getValueAt(selRowIndex,selColIndex).toString();
buff.append(val);
return buff.toString();
protected void importString(JComponent c, String str) {
JTable target = (JTable)c;

//int index = target.getSelectedRow();
int row = target.getSelectedRow();
int column = target.getSelectedColumn();
target.setValueAt(str, row, column);
protected void cleanup(JComponent c, boolean remove) {
}Now I want to put in the following functionality into my program...
[1]prevent dragging and dropping text in to the same table.That means I dont want to drag a cell content from Table1 and drop to another cell in Table1. Want to drag and drop cell content only from Table1 to Table2.
[2]Change cursor on a un-defined Target. That means how to prevent a drag from a particular column in Table1.Also how to prevent a drop to a particular column in Table2. How to change the cursor to a "NO-DRAG" cursoror "NO-DROP" cursor.
Could it be done using Drag Source Listener and drop Target Listener?.
If yes,How can these listeners attached to the table and how to do it?
If No,How Could it be done?
[3]Want to change the background colour of the cell being dragged and also the background colour of the target cell where the drop is made...
[4]Is there any out of the box way to make an undo in the target cell(where drop was made) so that the old cell value is brought back.
How can I extend my code to take care of the above said things.
Any help or suggestions is greatly appreciated.....

Drag and Drop in JPanel having GridBagLayout

Hi,
I have a JPanel (longitudinal) which has labels with imageicons (actually they are created using javax.media package and other JAI packages, but for simplicity sake labels are good). These labels are arranged longitudinally one below the other.
I have to implement drag and drop for these labels. I should be able to change the order etc. of the labels using DnD. I have been able to do that successfully. From the mouse coordinattes when the mouse is released, i calculated the grid on the layout, and then add the component to the panel in the grid.
All is well, but it doesnt end well :-(
The problem I am having is that when i releaase the mouse button, the component gets added on top of the component that is already there in that grid.
Is there a way that they can adjust positions, and the other labels move one grid down when another one is added in the same grid??
I would really appreciate any help. I did a lot of work to come to this level, and now i have just run out of ideas.
Thanks a lot in advance!!

Drag and drop pdf files to Acrobat plug-in dialog

Hi guys,
I have an Acrobat plug-in application based on ASDK7 use MFC, it has a UI dialog could make user add files to the dialog.
Now, I need to implement drag and drop files to the dialog.
But the file is simply opened by Acrobat always when I drag&drop files.
Drag&drop works fine in simple MFC project in Windows 7.
Is there need any settings in Acrobat preference?
Or how can I stealing drag acceptance from Acrobat App class in code?
Thanks a lot!

But Acrobat 9 also cannot work on my Windows XP enviroment.
I also tried Acrobat 10 on Windows 7, not worked too.
Thanks for your concerns. Regarding "I would recommend that you submit a formal support case with our Developer Support folks.", what should I do?

Gantt drag and drop

Hi.
I'm trying to implement drag and drop in a dvt:schedulingGantt ADF component. I've managed to get it sort of working. I can click on a 'taskbar' and drag it to another 'resource'.
But how can I get a reference to the Task that is being dragged? I can only get the key to the resource I'm dragging from, not the specific task that I'm dragging..
I'm doing this:
RowKeySet rowKeySet = transferable.getData(rowKeySetFlavor);
and get the key (rowid) out of the RowKeySet, but thats the key to the resource, not to the task.
I really need to get a reference to the dragged task, does anyone know how to do that?

User,
A timely question.
Have a read of Data Visualization Components Demo - question to Oracle people
Oracle has just posted the source for those demos.

Drag and Drop (Trying to do a copy but it does a Move instead)?

I have implemented drag and drop throughout my application and it works fine as long as I drag from a non-editable component (Table, TextArea, etc.) to an editable component (TextArea or TextField). However, When I drag and drop from an editable component to another editable component it does a move instead. How do I force it to do a copy? I looked at the description of exportAsDrag(JComponent comp, InputEvent e, int action) method and it even says for the action that no matter what you put in there "...the value may be changed during the course of the drag operation". What exactly causes this possible change and how do I prevent it from happening?
This is the constructor I currently have:
public TextAreaPanel(Document doc)
super(doc);
setMargin(new Insets(12,12,12,12));
setDragEnabled(true);
addMouseListener(new MouseAdapter()
    @Override public void mousePressed(MouseEvent e)
      if(e.getButton() != MouseEvent.BUTTON1)
        TextAreaPanel area = (TextAreaPanel)e.getSource();
        area.getTransferHandler().exportAsDrag(area, e, TransferHandler.COPY);
}I forgot to mention before. The location of the component having the text copied into it is in a different JInternalFrame than the one where the text is being copied from (not sure if that matters or not).

If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
Connect the micro USB cable to the Apple TV and to your computer.
Open iTunes.
Select your Apple TV in the Source list, and then click Restore.

Drag and drop in ALV tree

Hi All,
I have a small requirement, I have to implement drag and drop functionality in ALV ( simple trees ) in such a way that the entire contents ( Folders and its sub folders ) have to be copied. As of now i am able to drag and drop
one at a time, ie drag and drop folder and then again drag and drop its sub folder. Any solution to drag and drop both folder and its sub-folders in one step.
example program -> rsdemo_drag_drop_tree_multi which allows drag and drop of folders one at a time.
Thanks and Regards,
Kiran.
