Drag and drop, it won't release the file.
Upon booting up my 15"MBP with osx Lion, when I drag and drop a file, it won't release the file. This happens across files, other programs, etc. The only fix is to put the computer to "sleep", then when it turns back on drag and drop works fine.
Is there a fix for this issue? It happens on every boot up.
To clarify, it's not just Air DIsplay but any third-party video driver. When any of these is installed (not even necessarily active) on a MBP5,1, MBP5,2, or MBP5,3, you'll have this issue. The workaround is detailed here: Air Display on Lion with NVIDIA 9400/9600

When moving a file using drag and drop, as I hover over the destination folder it no longer opens, so I can't drop the file into the folder. Why? I have a heirarchical embedded folder structure under \Documents. Usually, as I drag the file to be moved over the various folders, they will blink twice, then expand/open to reveal contents (in Finder). Now, when the file to be moved is held (hovering) over the destination folder, it will not blink or expand, so there's no place to drop the file. If I release the mouse button, the file image disappears, showing that it is "going back to the place it came from", a.k.a. was not moved. This just started happening. I noticed it after upgrading to Mavericks. Is this a bug or could anything else be causing this?
As of today, Apple Support discovered during a remote support session with me that the same thing happens on their own system. It is isolated to "Column View"; the Icon and List views in Finder behave correctly. Issue is being escalated to engineering, and Apple will call to report status in a couple days. In all likelihood, this is a bug that will need to be addressed in a future update.

My PC has all of my iTunes and it recognizes my iPhone 4 device but I cannot drag and drop the songs. How do I copy the songs to my new iPhone without having to re-purchase everything? Unfortunately, It appears I no longer have iTunes Music Library.xml on my PC.
My husband and I are using the same iTunes account on all mac & pc computers, but the libraries are different on each machine. We always manually manage our music (no auto sync). iTunes is up to date on the PCs. My husband uses our joint iTunes account on his pc, but once again, has a different collection in his library from those on the other machines. He can't load any music from his PC to his iphone 4. I can load music from my mac library to my iphone 4s, but cannot load from my pc library to my iphone 4s. How can I switch my main library that it syncs with from the mac to the pc?

I have a 5th gen iPoc Touch. In the past, with the Classic, I could drag and drop from my iTunes music to a Classic playlist through iTunes. Now, the playlist I create in iTunes doesn't show on the Touch. I have maybe 29 GB of music on my Touch. I have already created playlists in iTunes that have substantial amounts of songs in each. How can I get those playlists on the Touch without doing a total sync that wipes the iPod? Is there a way to do it?
As well, I am noticing here that my 5th gen iPod doesn't show as a registered device. How do I register it?For how to sync see:

I like to make MP3 CD's when I have people over, or when my friends have people over so I can just pop them into the CD player and let them play all night without having to worry about changing the CD or anything. Well, Apple's music is in AAC format, so I have to convert the songs to MP3 files using the converter in iTunes. So I'll convert them to MP3's and just delete the AAC file so I don't have doubles. The problem is, the next time I plug the phone into my laptop to transfer new purchases, iTunes thinks that the songs I converted aren't there anymore because the phone has them as AAC files, and iTunes has them as MP3 files, so it doubles the music again...EVERY time!! It's very frustrating! So this is why instead of clicking Transfer Purchases, I would like to be able to just drag and drop the songs I want from the Purchased list on the phone into my iTunes library. I hope I explained this right...lol. Unfortunately, it doesn't seem like I'm able to do that. I'm hoping maybe somebody here can help me out and give me some pointers on what to do about this. Thanks!!
That stinks! I can actually do that at my house...I just plug my iPhone right into the wire that's plugged into my receiver in my living room...but some of my friends aren't "technology savvy"...lol...so they just have DVD players and I'll put the CD in there because it will read an MP3 disc. What's funny, is I have the phone set to "Manually Manage Music", and when I plugged it into the laptop just now, the one song I downloaded last night on the phone, transferred over to the iTunesl library. That NEVER happens. And it only transferred the one song...it didn't double the other songs like it ususally does. I swear, iTunes does what it wants, when it wants sometimes...lol. Thank you for your quick response.

I would like to archive hundreds of my emails that currently exist in my apple mail email filing system by moving them into file folders in the finder. I can do this easily with a single email but it wont let me do it with multiple emails or a complete folder. Is there any way of do this easily?
Thanks very much for this. However, I understand how dragging and dropping files normally works. It just seems the it wont work when you do it with emails when you are transfering them into a normal finder system folder. If you highlight one file and drag it to a finder folder it works, but when you drag multiple, it just wont let you do it.
Is there any work around for this? Thank you once again for your time. -

Hello All,

Putting the icons on the labels donot work as i would like to drag multiple icons from the left side and drop them on the right side. CAn anyone please help me with this.
Thanks in advance
smithaThe other option besides the drag_n_drop support
http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.htmlis to make up something on your own. You could use a glasspane (see JRootPane api for overview) as mentioned in the tutorial.
Here's another variation using an OverlayLayout. One advantage of this approach is that you can localize the overlay component and avoid some work.

Firefox: Drag and drop access revoked if open the same applet in new tab
I have an uploader application that allows for drag and dropping of files from the desktop, works great. In Firefox 3, if you go to the uploader and drag files onto it it works, if you then open a new tab in the same window and navigate to the URL that contains the application you can drag and drop files into that new application window, if you go back to the previous tab however you can't drag and drop files on to that instance of the app anymore. Is this a known issue?
Thanks,
SamThis is an applet?

Drag and Drop Multiple Pictogram elements from the Palette
I have created custom Objects in the palette that can drag and drop individual pictogram elements using a class that extends AbstractAddFeature. What I would like to know if it is possible to drag and drop an item from the palette that contains multiple pictogram elements, such as task1, task2 and a connection between them? I cannot do this with my class from above since
@Override
public PictogramElement add(IAddContext context) {}
only returns one PictogramElement.Hi,
In my editor I am adding rectangle with associated label that are separate pictogram elements. However they are both linked to the same business object and more linked to each other.
Please look at example from my code:
@Override
public PictogramElement add(IAddContext context) {
final Task addedTask = (Task) context.getNewObject();
final ContainerShape target = context.getTargetContainer();
final IPeCreateService peCreateService = Graphiti.getPeCreateService();
final IGaService gaService = Graphiti.getGaService();
final ContainerShape containerShape = peCreateService.createContainerShape(target, true);
int width = 0;
int height = 0;
width = context.getWidth() <= 0 ? getWidth() : context.getWidth();
height = context.getHeight() <= 0 ? getHeight() : context.getHeight();
final Rectangle invisibleRectangle = gaService.createInvisibleRectangle(containerShape);
gaService.setLocationAndSize(invisibleRectangle, context.getX(), context.getY(), width, height);
// create and set visible rectangle inside invisible rectangle
RoundedRectangle roundedRectangle = gaService.createRoundedRectangle(invisibleRectangle, 20, 20);
roundedRectangle.setParentGraphicsAlgorithm(invisibleRectangle);
roundedRectangle.setStyle(addedTask.isOnlyLocal() ? onlyLocalStyle : getStyle());
if(!addedTask.isAtomic()) roundedRectangle.setLineStyle(LineStyle.DOT);
gaService.setLocationAndSize(roundedRectangle, 0, 0, width, height);
insertInside(peCreateService, gaService, width, height, containerShape, invisibleRectangle, addedTask);
ContainerShape labelShape = addLabel(target, addedTask.getId(), width, height, context.getX(), context.getY());
link(containerShape, new Object[] {addedTask, labelShape});
link(labelShape, new Object[] {addedTask, containerShape});
updatePictogramElement(labelShape);
layoutPictogramElement(labelShape);
addInternalPorts(addedTask, containerShape);
updatePictogramElement(containerShape);
return containerShape;
I think that linking or making somehow relation between pictogram elements should be enough. -
Drag and Drop inside JTable: what draws the 'insert' line during the drag?
I'm trying to reconfigure a rather complex table with a fair number of custom renderers to include drag & drop of rows for resorting the table. Everything is working great, except that as I drag the rows there is no indication of the current insert point (i.e. the line that appears between rows). When I make a simpler table I see the line... I'm not sure what aspect of my current table is blocking this function. I'm writing in the hope that can someone can direct me to the method(s) responsible for drawing this line.
Thanks!To elaborate a bit for anyone who might read this. I inquired with the Substance developers and they hope to support this feature in v5.1 (which requires SE6), but have no plans to update v4.3 (the last release before a switch to SE6).
Also, I'd still be grateful for any info pointing me to the Swing methods that draw the drag line. -
Uploading file with Java: Java won't release the file.
I'm trying to upload .log files to a webbsite using a form. It uploads fine, that's not the problem. The problem is that I want it to delete the file afterwards to save disk space, but the application doesn't release it. I thought I might just be doing something wrong with the delete function, but even deleting it manually through Windows doesn't work. Any ideas?

Recent update on PS elements 12, I can no longer drag and drop from one photo to the other.
Hello I hope someone can help, I am using Adobe photoshop elements 12, I am using a PC with windows 8.1.
any ways I recently was prompted that I had a update for PE12, as i always do i followed the exact instructions after the restart as prompted. I was no longer able to drag on photo to another photo, i like to use a blank page design a background and then choose a couple photos to collage or group together on one photo but now i cant drag the selected/croped or even a whole picture any one else have this probleum i am on chat with an adobe professional but even they seem stumped, maybe someone can help.It's a bug introduced with the 12.1 update when your images are in Tabbed view. Dragging from one to another doesn't shift focus to the second image so you can't drop it. Switch to Tiled view (Windows> Images> Tile) and drag & drop will work.
If Tile is greyed out you need to switch on Floating Documents.
Cheers,
Neale

I drag a video clip from Event to Project into my imovie I've started. The video clip length changes from 7.9 seconds to 4.9 seconds. How can I stop that length from being changed?
If you are using transitions either side of the clip they will use some of the clip to generate the effect, there isn't anything you can do unless you remove or shorten the transition.
If you aren't using transitions it may be that you are only selecting part of the clip in the event window, try dragging out the yellow frame to include all the video you want in the project.
