Java script- drag and drop

Can i use java scripte to do a drag&drop interface?I want to move a picture(.jpg or.gif) to anywhere on ie.

There are drag and drop functions in DHTML that you can use in Javascript :
ondrag
Fires on the source object continuously during a drag operation.
ondragend
Fires on the source object when the user releases the mouse at the close of a drag operation.
ondragenter
Fires on the target element when the user drags the object to a valid drop target.
ondragleave
Fires on the target object when the user moves the mouse out of a valid drop target during a drag operation.
ondragover
Fires on the target element continuously while the user drags the object over a valid drop target.
ondragstart
Fires on the source object when the user starts to drag a text selection or selected object.
ondrop
Fires on the target object when the mouse button is released during a drag-and-drop operation.

Safari for Mac, webpage with Java applet, drag and drop area not working.

At my company, we have a web page that our users access to submit media files, (QuickTime, Audio, images...), for transcoding for delivery. The web page consists of a java applet, with an area that our users drag and drop media file into.
After updating to Safari 5.1.2, the applet will not work anymore. Instead, the browser will "open" the quicktime and play it, instead of allowing the Java Applet to do it's job.
CAN I TURN THIS FUNCTIONALITY OFF??
I read that Safari 5.1.2, (when it was initially released), broke something with the THEN current version of Java, and everyone was awaiting the latest update (build 1.6.0_29) to fix it. Unfortunately, this update did not fix my issue with the functionality of dragging and dropping media files into the web page.
It seems to me, as if, there is an over-arching functionality setting (or something) that needs to be either turned off, or in some other way DE-prioritized.
Anyone have any ideas?

Thanks for quick reply and help. I am able to drag multiple files but this is giving problem in case of filename with spaces like "abc def.png". Can you please put some thoughts on this.
DataFlavor uriListFlavor = new DataFlavor("text/uri-list;class=java.lang.String");
               Reader in = (Reader)t.getTransferData(DataFlavor.plainTextFlavor);
               BufferedReader br = new BufferedReader(in);
               String uriStr;
               while ((uriStr = br.readLine()) != null)
                   URL url = new URL(uriStr);
                   String category = GalleryUtils.contentsPanel.getCurrentCategoryPath();
                   GalleryUtils.generateILPFromFile(new File(url.getFile()), category);
               }Thanks

PDF XFA form/internet browser/JAVA application/Drag and Drop

Hi guys,
I need to be able to open a PDF XFA form (a PDF document where I have some input controls and javascripts for validation) inside a JPanel.
If this is not doable am thinking if i can open this pdf form in a web browser by launching it from my java application.
And when I do this, I want to be able to drag and drop between the java application and the browser.
Anyone can tell me if that is doable?
Thanks and Regards,
Rawad

Tristan,
I am stuck in the same place. Perhaps we could work on this together.
I am trying to drag a single item from a JList to a text editor, Word, etc. I have two problems:
1) I can't seem to get just the item in the JList to drag. It wants to drag the entire JList component.
2) How does one define the remote application as the drop target? Have not found any examples either.
Is the drop target actually the system clipboard?

Java 2D Drag and Drop

Hi, I am trying to write some code which does the following. When a use clicks on th JPanel a circle is drawn. What I now want to do is allow the user to select that circle and move it to a different position. Could anyone help me with this. I have implemented the drawing of the circle, I am not stuck on how to move the circle to a different position. Hope someone can help. Thank you!

You can use Shape.contains method to see if your click point is in the circle and then animate movement appropriately.

I am unable to drag and drop image files in a JAVA supposrted site. I have all the lastest versions of softwarte here - everything is up to date.

I am no longer able to drag and drop image files int this JAVA supported site. It had always worked flawlessly in the past.
I would open the site, go to Send Files, allow access, fill out the fields and then drag and drop my image files. Now I can only use the ADD (+) button to do so.
I have the latest versions of OS-X Lion and JAVA installed on my computer
http://www.clippingprovider.com/CP_II_EU/Welcome.html

This is the Tech Sheet on the subject:
Photoshop Help | Managing paths
It contains this item under Manage Paths:
When you use a pen or shape tool to create a work path, the new path appears as the work path in the Paths panel. The work path is temporary; you must save it to avoid losing its contents.
Ok, the red you referred to is a Stoke you added. Then QuickMask is not involved.

Drag and Drop and java.io.NotSerializableException

I have been implementing some code to essentially allow me to drag and drop from one JTree to another. The requirement was to be able to drag multiple nodes at one time and drop them on the other JTree in the order selected.
I was getting a java.io.NotSerializableException when I was in the drop code in the destination jTree and could not figure out what was going on. Basically, I was wrapping all the objects that i wanted to transfer in a custom ArrayList subclass that implemented transferable. The NotSerializableException was was indicating that the object in the JList was not serializable.
If you are getting a NotSerializableException and you have defined a custom DataFlavor like so:
public static DataFlavor DATATYPE_TRANSFER =
        new DataFlavor(
           TransferableImplementor.class, // make sure that this is the class that implements transferable
            "Datatype Information");make sure that the .class is indeed the class that implements the transferable interface (and not some other random .class). You can be led down a wild goose chase on trying to make sure every object in your Transferable implementor class is serializable, when the problem lays in the DataFlavor instantiation.

Drag and Drop UI in WD Java CE 7.2

Hi
In CE 7.11 we get DragItemListBox and DropItemListBox UI elements in Webdynpro Java to implement the drag-drop functionality.
I suppose this has been enhanced with the CE 7.2 release. But I am not finding the proper way or tutorial to implement the drag-drop functionality in WD in CE 7.2.
Please suggest the ways to implement this.
Thanks and Regards,
Sayan Ghosh

Hi Robin / Pradeep,
Thanks for the suggestions. What I found out was from CE 7.11 EPH1, the Drag and Drop feature was introduced. That time it was limited to ItemListBox.
With the release of CE 7.2, this feature has been majorly advanced. Like you can have DragSourceInfo UI elements from dragging from an image, table, ItemListBox, tree and so on... and a corresponding DropSourceInfo UI element where we can drop the dragged elements. The tag value of a particular DragSourceInfo and DropSourceInfo should be same.. so that u can drop the dragged items. Once dropped, the DropSourceInfo can fire an onDrop event where u can do all ur logic.
Moreover there is also something called DropTarget UI which basically provides a Container under that which can hold any UI element. The entire container under the DropTarget UI element is the drop area. We just need to to add a DropSourceInfo under that and provide the proper tag name and use the onDrop event.
Regards,
Sayan Ghosh

Drag and Drop between two java applications

Drag and Drop - Java -- other application

Hi,
I'm writing an application, which requires to transfer the content of textfields through Drag and Drop to any other application.
Basically this works, but in combination with some applications, e.g. Mozilla, it happens, that the DragSourceListener doesn't recognize, that the Drag and Drop - operation is finished.
Because of this I get an InvalidDnDOperationException, when I try to start a new Drag and Drop - operation.
Can anyone tell me, how to solve the problem?
thanks in advance

Drag and drop file onto java app

Hi,
I would like to drag and drop a file from windows explorer onto a panel in my java app.
All I need is that when the file is 'dropped', I can get a reference to the path of file.
e.g.
There is a file, C:\myFile.txt
There is a String in my program called 'filePath'.
I start my java app and dnd the file onto it.
I want the path of the file to be assigned to the filePath String.
I can then do more proccessing on the file which I already know how to do.
Can anyone help.
Thanks,
Jim

Drag and drop of Windows icons inside Java......possible ?

Hi all !
does anybody know if it's possible to do drag and drop of windows icons (like folders) into Java Frames or other containers ?
I'd like to write an application where the user can drag Windows folders inside a Frame/Container and collect Folder information (the path to the folder)
Is it possible to do it ?
Thanks a lot
Francesco

Hi,
It is possible.
You can drag platform independent objects like folders, icons etc. from the native platform to your java app.
The Java-Object you need in this case is a
DataFlavour like
DataFlavor.stringFlavor // for text
DataFlavor.javaFileListFlavor // for folders
in the tutorial jacob has linked you find more about this.

Drag And Drop Java Portlets

Hi,
How can we develop Drag and Drop (DnD) Portlets. Does Oracle Portlet provide such functionality.Can someone guide me or have any documentation on how to create Java Portlets that can be dragged arround i.e. just like on google site http://www.google.com/ig. I am using 10.1.0.4. Thanks

Is there any kind of documentation available as how to build this kind of functionality. What API's to use. Lifefray and StringBeans Portal provides DnD functionality so curious if it's also doable using Oracle Portal and if so how to start on it. I am more interesetd in docs. and API's to use for building our own.
Thanks

Drag and Drop file FROM Java app TO native desktop

I'm a litte new to Drag and Drop. After a few days of looking around I've been through enough examples to copy and paste some skeleton code and get it working in my own application.
What I haven't gotten any answers to (after searching on google, newsgroups, and here) is if it's possible to drag something from a Java app to the desktop or file browser, and have java create a file there.
I know you can drag text to native apps, so I was wondering if you could make a Transferable object that's different than StringSelection(), like a file stream or something.
Thanks,

Drag and Drop UI Scripting?

Some (unscriptable) applications such as iMovie rely on drag and drop for key functions.
Is there way to do drag and drop using UI Scripting?

If there's a way to do that, I would be extremely happy to learn it.
