LR v1.0 - Qimage interaction (no image drag and drop)
I am able to drag and drop image files from Bridge-CS2 to Qimage templates for printing (I am also able to drag images from Bridge2-CS3 beta to Qimage.)
I have NOT been able to drag the same image files from LR v1.0 to Qimage (the cursor shows the image being dragged until leaving the LR window, then the cursor turns to a slash-circle - "NO").
Anyone had success, or similar problems?
Thanks.
Joe
Try using Qimage in export actions and export to it.

How do I stop finder from opening a new window every time I download an image (drag and drop)?
Before I updated my computer I could drag and drop a new image from the internet to wherever I wanted on the desktop. Now when I download a new image from the internet it opens the "Desktop" finder windo. Also it systematically downloads the new image to be placed underneath the last downloaded/organized file. How do I stop it from doing both of these things?
Try relaunching the Finder > Relaunch Finder… from the Mac OS X Finder

Hi all,
I am writing a program, with 2 JPanels, the first one is with 4 images (JLabel), I need to drag the images and drop on second JPanel. When the image is dropped, it should also allow dragging to desired position in that JPanel(through MouseMotionListener).
I read a lot of examples about DnD, TransferHandler, I knew how to implement drag and drop between JPanels, but still have no idea how to implement both. Can anyone advise a brief idea how can I do.
Thank you so much....Read this: http://forum.java.sun.com/thread.jsp?forum=57&thread=516990
It shouldn't be a big streach to convert the panel to an image.
If you have problems after trying this out, repost. -
Cap 4 Corrupts on image drag and drop
Hi All,
I have run into a very frustrating problem with Cap 4. I will be working along creating slides then when I drag and drop a JPEG image into the movie:
1. the timeline on that side disappears 2.the project corrupts and will not save or open previously saved project.
Anyone have any ideas?
ThanksHi there
Perhaps try first saving the image, then using the Insert > Image menu command. See if that results in better behavior.
Cheers... Rick

Preview image drag and drop from offline master
I've always loved the ability to drag and drop previews even though the master is offline.
Why can't i do this in ap3?
It seems to be hit or miss, mostly miss for me.
It's great to take home a library of offline masters and quickly mock-up layouts using ap1-2
Any solutions?You started the thread off basically telling everyone that drag out of the previews didn't work if the masters were offline in Aperture 3. Rereading your posts I don't really see a question in there anywhere.
This post is a support question. It is not my intention to make broad statements that this behavior is widespread for every ap3 user. The apple support forums are radically different and I'm a bit confused as to how this new system works.
Frank Caggiano wrote:
Well have you run any of the basic trouble shooting tips show at http://support.apple.com/kb/HT3805 for s start?
Now if you're interested in trying to get this fixed I'd hold off on going into the library and maybe give us the backstory. I still don't know what equipment you're on or how this all started.
I have done all those steps including using disk utility to repair permissions.
This behavior is consistent across 3 computers with their own unique ap3 licenses:
2011 17" MacBook Pro
2010 Mac Mini
2010 15" MacBook Pro
I've upgraded all computers to Aperture 3 5 months ago and I've seen this issue ever since. -
Drag and Drop Interaction - Drops Items
Hi
I am using the new Interaction template for Drag and Drops. This seems to work great but there is one thing I am struggling to do.
Is there anyway you can restirct how many items can be placed on a drop zone? At the moment you can drop more than one item to a drop zone and they overlap. My ideal solution would be that you can only drap one item to a zone or that when you drop an item to an area that already has one there, that it replaces it with the new one that was just dropped.
ThanksYes, you can do what you are asking. Here are some great tutorials from Pooja, an expert! She explains in the videos how to do exactly what you're asking. https://www.adobeknowhow.com/courselanding/what-s-new-adobe-captivate-7.

Captivate 8 drag and drop interaction not working
Hi, I am working with Captivate 8 and created a drag and drop interaction using the drag and drop wizard. For some reason when I preview the interaction some of my drag sources work and others do not. I have searched high and low for what I may be doing wrong but I can't figure it out. I created types when making the interaction so it doesn't make sense that some should work and others do not. Thank you for any help you can provide.
Ok, so I inserted the screen shots below. I realize the items are overlapping in the wiring. I did change that and try it but it still didn't work. Maybe I need to completely rebuild it? I created types so that 9 would go to one target and 6 to the other.Thank you so much for your quick help on all of this.

How to add imge to another image box by drag and drop
Hi all
i am using flex 3.and my problem is to drag an image and drop to another box or image what ever.just need to display the copy of the source image in its drop target.is it possible drag an image?if it is then how?please help me.
thanks and regardsthere are examples of image dragging and dropping here:
http://www.adobe.com/devnet/flex/quickstart/adding_drag_and_drop/
i imagine for your problem, you want the final example, and instead of passing across an integer value, you want to pass across the image source. -
Embedded drag and drop not working
Hi,
Hoping someone can help as have got 90% of the way through a project and hit a wall at the final (end-of-level-baddie) problem.
I'm currently embedding old AS2 activities (build by a second party - now not operating/contactable) into a new AS3 menu system.
Most of them I've managed to port across and embed without issue. Unfortunately embedding the drag and drop activity is proving to be, for want of a better phrase, a complete drag.
I've managed to decompile the code, so have put a few trace statements in to find out what might be going wrong. Looking in the collision detection part of the code, the problem appears to be that when the activity is embedded, although the index of the drag clip is returned fine with its corresponding index number, the index of the drop clip is returned as 'undefined'.
The activity works fine in a standalone flash player, with both indexes returning their respective numbers. However not so when it's embedded.
I'm guessing that this is a levels issue, but is there any easy way that I can force the AS2 drag and drop game to act as self-contained and ignore its parent holding clip?
Thanks in advanceHi kglad,
Thanks for replying (you've helped me out before :-) )
A search of the classes reveals only one mention of getDepth() on a text field, which is irrelevant at the mo (as the engine's just creating image drag and drops)
The main activity stage is created by an EngineClass (which drives all the activities I've been adapting, but wasn't a problem with less layer critical ones).
There are three lines I can see where the activity stage is created using 'getNextHighestDepth()'
this.mWhere.createEmptyMovieClip("activity_mc", this.mWhere.getNextHighestDepth());
this.mWhere.createEmptyMovieClip("activityMask_mc", this.mWhere.getNextHighestDepth());
this.mWhere.createEmptyMovieClip("toolbars_mc", this.mWhere.getNextHighestDepth());
All the drags and drops are then created within this activity_mc. When I run the activity as standalone (where it works), and drag an item onto a drop zone, the traces I set up on the Drag and Drop items report back the following:
DragObject: _level0.activity_mc.container_mc.dropItem2.dropSkin.greyBorder.whiteBG
DropArea: _level0.activity_mc.container_mc.dropItem2.dropSkin.greyBorder
When I run it embedded in the AS2 wrapper it then fires back the following after an attempted drop:
DragObject: undefined
DropArea: undefined
...and the item refuses to drop on the dropzone, returning to where it came from.
The tiny amount of knowledge I have makes me (probably mistakenly) assume that if I could place the activity_mc layer on root, then everything would be contained within the embedded clip and the layering wouldn't go so wonky. But in reality I've got no idea! To make matters worse, the original drag and drop activity is itself inside another as2 wrapper which contains some navigation buttons... -
Working on storyboards/ID for a project that must be WCAG 2.0 compliant.
Does anyone know if drag and drop exercises can meet this requirement? (Keyboard equivalents?). Also, what about roll-overs?
any advice/help would be appreciated!
ThanksThe usual answer is NO. Best to avoid drag and drop interactions if you are going for accessibility with a single course that all users must use.
My preference is to have two versions of the course. One for general users that allows for more engaging interactions such as drag and drop, and another very plain but eminently accessible version that has everything non accessible stripped out. I realise that this means a slightly higher budget expenditure, but the reality is that forcing all users to use accessible courses penalizes the majority of users if it denies them the ability to consume more engaging content.
By all means cater to those with accessibility needs. They certainly have rights.
But don't forget that the other much larger part of your audience also have rights too. -
Is it possible to add a drag and drop interaction to a called image in a contaner?
this forum is my last hope =( i know how to do drag and drop
by itself, however right now i have my flash set up so that when
you click BUTTON A, it does:
on (release) {
_root.gotoAndPlay ("photo1");
once it goes to "photo1", on that frame, i wrote actions on
the frame to:
var myMCL:MovieClipLoader = new MovieClipLoader ();
myMCL.loadClip ("images/heritageBrochureFront.png",
"container_mc");
stop();
so it loads my picture into the container. my question, once
the image it in the container, can i add drag and drop interaction
to it? i would really love an easy solution.yes. there are a couple of ways to do this.
one is the create a child movieclip of container_mc and load
into that child and assign your onPress/startDrag
onRelease/stopDrag methods to container_mc.
a second way is to load into container_mc (like you're
currently doing), wait until loading is complete (ie, use the
onLoad method of an mcl listener) and then assign your methods to
container_mc. -
What am I missing. The opacity is at 100%. The drop target is a highlighted box from objects. I am using Captivate 8.
Hi there,
You might want to make sure your Depth setting is not set to Back instead of Front on your drop target(s).
The Depth setting is accessed via the Drag and Drop window/panel under Format setting while you have your drop target selected.
If your Depth setting is set to Back, especially if your opacity is set to 100% on your highlight box/drop target, your drag image would go behind your drop target giving the effect of disappearing behind your highlight box - especially if the drop target is larger than the drag 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.*;

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) {

}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.

Drag and Drop is duplicating images on an iPad...?
Hi,
I have a drag and drop interaction in my CP8 course. I'm dragging several sources into one target, and it's functioning perfectly in all browsers. However, when you complete the interaction on the iPad, it's duplicating the last image that the learner drags into the target. It doesn't matter which drag source it is, it's always duplicating the very last one.
Any idea why this would be happening or how to fix it?
Thanks,
KristenThanks 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
