Drag and Drop Image to native Application
Hi there!
I've spent quite a while now, searching for answers for my problem. I want to be able to drag and drop some JComponent - let's say a JPanel - to a native Windows application (like MS Office...). I know this is possible and I know that windows requires some special Image format (like DIB or Bitmap). Now comes the tricky part :-) I was not able till now, to get my custom Transferhandler to work to obtain this task. Does anyone have some code snippets which to something like this? Or does anyone have any good hints how to do this? I've really searched the whole net all over and didn't really find anything helpful ( not even here, or on the rockhoppertech site).
I whould highly apprechiate some help!
Thank you all in advance :-)

i have the same problem and Sun doesn't seem to have an answer to this question. The DnD works in Mac OS, but not on Window 2000/XP.

Drag and Drop Image onto Native Application
I am interested in dragging and dropping an image
from a java app to a native app (such as MS-WORD,
etc), i have been able to DnD text but have been
unsuccessful with images. any tips, resources?
Thanksthanks, i already saw that.
is there a way I could drop an Image onto a native app such that when it drops, another component / object such as a frame loads?

Drag and drop images from the OS or select images over filebrowser
Hello,
I want to create an image upload tool in JavaFX with similar functionality like Jumploader (http://jumploader.com/). The users should be able to select images from the filesystem that will be resized and uploaded to their website, similar as in Facebook. The difference is that I want users to be able to crop images directly in my application. This is something, other upload tools do not offer.
I was searching weeks on the web trying to find a sample on how to drag and drop images in to a JavaFX 1.3.1 app or also to create a file browser. I have found many examples but they seem to be outdated. Is it to early yet to try and start projects like these with JavaFX as JavaFX is still under development? Or can anybody lead me in to the right direction?
Thanks,
ChrisTo be more precise, you can setup a JComponent or JPanel on top of your JavaFX nodes that has a TransferHandler that can convert the (AWT/Swing) images dragged to the app to JavaFX image and then insert it into the underlying node.
As for the file chooser itselft: ListView and the JavaFX composer can allow you to create one quite easily. TreeView can aslso be used to a lesser extend (still a big buggy). For both of these, there are small bugs in the Cell API that may (or may not) prevent from displaying a proper thumbnail in the cells.
You can also use a regular JFileChooser if you do not mind the dialog box having a different LnF from the rest of your application. -
Can`t drag and drop images into PSE5
hi,
i`m from germany, so sorry for my english..
i use pse5 since a few years and a few month with windows7..today i had to reinstall it and now i can`t drag and drop images from explorer or acdsee to PSE workspace. i get no error-message , only this circle with a diagonal line..
i CAN drag and drop images from the editor..
- i reinstalled it and repaired it
- tried diffferent compatability modes
- i don`t run the program as a administrator ( tried it- it was the same)
so can anyone please help me?
thank you so much!
mareenTry making a direct shortcut to the Organizer and then the Editor.
You should then be able to drag and drop on to the desktop icon.
On Windows right click on the desktop and select New >> Shortcut
Browse to Computer OS C:
And find the PSE Organizer application in Program Files or Program Files (x86) on Windows 7 - 64 bit.
Inside the Adobe >> Photoshop Elements Organizer (yellow folder) you are looking for an application file “PhotoshopEementsOrganizer” with six small icons (e.g. representing thumbnails - could be different in PSE5 but look for the exe file)
Select it and click OK
Click next
Rename by taking out Photoshop Elements leaving just the word Organizer
Then click finish
You should now be able to launch directly form the desktop by double clicking on the icon.
You can set up a similar direct link to the Editor application.

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.htmlThis 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. -
With the new Photos app, I can no longer drag and drop photos into other applications as I did with iPhoto. For instance, I have a photo collage app that in the past, I could just drag in the photos I wanted to include. Now, I can DRAG the photos, but they do not DROP. So, I have to go through the export process. It is tedious. What am I missing? Where can I turn on the drag and drop feature for Photos?
YOu're not looking in the right palce. That's inside the iPhoto Application.
You need to look inside the iPhoto Library
As I sid above:
Go to your Pictures Folder and find the iPhoto Library there

Why can't I drag and drop images from the browser into other programs?
Ever since I upgraded to Firefox 4 (even after I upgraded again to Firefox 5) I have been unable to drag images from the browser into other programs, including MS Paint and IcoFx. I receive an error message stating that the file (the address given lists it as being located in the temporary files folder) cannot be found.
Prior to this I had always been able to conveniently drag and drop images for easy editing without having to save first and then open them. This feature is important to me, as I work with graphics very often, and is still available in Chrome and Internet Explorer. I love Firefox though, and hope that there is something I can do to fix the problem.I had this problem on Windows 8.1.1 and iTunes 11.2.2.3
To resolve it from within Itunes I did : Edit, Preferences, Sharing.
I took the tick out of "Share my library on my local network"
Click OK.
Closed iTunes/
Reopened iTunes and I can drag and drop.
I went back into Edit, Preferences, Sharing and put the tick back and clicked OK.
Works fine now. -

sunnyWell, I don't really understand the DnD interface so maybe my chess board example will be easier to understand and modify:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=518707
Basically what you would need to do is:
a) on a mousePressed you would need to create a new JLabel with the icon from the clicked label and add the label to the glass pane
b) mouseDragged code would be the same you just repaint the label as it is moved
c) on a mouseReleased, you would need to check that the label is now positioned over your "drop panel" and then add the label to the panel using the panels coordinates not the glass pane coordinates. -
How come in Pages, i cannot drag and drop images?
how come in Pages, i cannot drag and drop images?
Yes you can in all versions.
It helps if you actually describe what you are doing.
Where are you dragging it from and where are you dragging it to?
In what version of Pages?
I suspect you are trying to drag an image into a Table, Header or Footer in Pages 5, which is no longer possible. Feature removed by Apple.

My pages has stopped letting me drag and drop images
my pages has stopped letting me drag and drop images, into the template
Just the one template or all templates?
Can you drag and drop an image anywhere on the page?
When you have a problem try and isolate it.
Not all images are placeholders.
Also if you get oddball things happening sometimes a simple restart of your computer will fix them.

How to drag and drop image between Windows platform and VM
Thanks.
Hi Deer2000,
There are several things you need to do first. You need a Transferable that can provide the image data in a format that the application likes. You will not be able to drop a serialized ImageIcon onto a native app for example. Most won't accept a binary stream even if you declare it's MIME type (e.g. image/jpeg) either.
You need to know what the native "clipboard" formats are. For example on Win32, DIB (device independent bitmap) and BITMAP are clipboard image formats. Learn the format and write an InputStream the can provide it. Then add your stream to a FlavorMap.
What is a FlavorMap and why do I need one?
Most native apps don't understand MIME types for data transfer. They have their own "clipboard" types. Java DataFlavors are based on MIME types. In order to provide a mapping between the win32 format TEXT and MIME types text/plain;charset=ascii you create a FlavorMap. Actually the default system flavormap does this type for you.
An easy way to add mappings is to edit $JDKHOME/jre/lib/flavormap.properties. For our custom image stream we've added the following entry:
DIB=image/x-win-bmp;class=com.rockhoppertech.dnd.datatransfer.BitmapInputStream
Other Win32 clipboard formats are:
WAVE
RIFF
PALETTE
ENHMETAFILE
METAFILEPICT
DIB
TIFF
Or please refer this URL, which gives a good idea about drag and drop in Java
http://www.rockhoppertech.com/java-drag-and-drop-faq.html
I hope this will help you.
