Drag and Drop and JGraph
Hi,
I'm trying to use drag and drop for adding nodes to a panel which has a JGraph component in it.
The problem is that when I add the JGraph, the panel which holds it (a JScrollPane) stops listening the drops... is there any way to solve this?
I thought that I could subclass the JGraph in order to have it manage the event, which doesn't look very good from an architectural point of view, but is the only thing I could came up with.
thank you very much!

Hi PlaySmile,
These features are not available in current version of Lync 2013.
From
https://support.office.com/en-us/article/Send-an-IM-a74b4cf3-1c56-413f-a22a-be19c9dcbb70?CorrelationId=d329f320-aa5e-41a3-b850-ce843912cb7c&ui=en-US&rs=en-US&ad=US
You can send a file or picture by doing one of the following:
a. Drag-and-drop the file or picture from your computer into the message window or text input area.
b. Copy and paste the file or picture from any Office program into the message window or text input area.
c. Press PrtScn on your keyboard to capture an image directly from your screen, then paste it into the message window or text input area.
Note: Your sent message will show a small representation of the file or picture. To open the file or see the full-size picture, the recipient clicks Save or Open, which transfers the file to
their computer. Also note that embedded images only show up in one to one IMs, not group conversations.
I also tested with the new client “Skype for Business”, the feature that drag and drop pictures from any browser to Skype for Business is still not available, but the feature that copy/past pictures
from browsers to Skype for Business is available.
Best regards,
Eric

Can i make a book in iPhoto without using any of the built in layout templates, which are too limiting when i have already cropped my pictures to show just what I want. Ideally I just want to drag and drop and arrange and size the pictures myself
If you have Pages you can create customs pages for your book as TD suggested. If you have Pages from iWork 09 or 11 this app will add 80 or so additional frames to those offered: Frames and Strokes Installer. Don't use it on the latest Pages version, however.
This tutorial shows how to create a custom page with the theme's background: iP11 - Creating a Custom Page, with the Theme's Background for an iPhoto Book. Once the page is complete to get it into iPhoto as a jpeg file follow these steps:
Here's how to get any file into iPhoto as a jpeg file:
1 - open the file in any application that will open it.
2 - type Command+P to start the print process.
3 - click on the PDF button and select "Save PDF to iPhoto".
NOTE: If you don't have any of those options go to Toad's Cellar and download these two files:
Save PDF to iPhoto 200 DPI.workflow.zip
Save PDF to iPhoto 300 DPI.workflow.zip
Unzip the files and place in the HD/Library/PDF Services folder and reboot.
4 - select either of the files above (300 dip is used for photos to be included in a book that will be ordered).
5 - in the window that comes up enter an album name or select an existing album and hit the Continue button.
That will create a 200 or 300 dpi jpeg file of the item being printed and import it into iPhoto. For books to be printed choose 300 dpi. -

After Dropping these icons on to the DropContainer i need to resize them.

Hi could someone help me please ? Ive just bought the new ipad and want to put some movies on it. I have already converted some movies using handbrake and tried to transfer them to my ipad and it just wont work. ive tried drag and drop and everything
bluztoo wrote:
Haven't really used any of them including VLC - actually use netflix on the ipad more than anything. I was able to drop an mp4 into imovie on my ipad and see it there. This was something I had shot as avhcd and converted with turbo.264. Played fine. Probably not what you want for a movie player though.
Well, turbo.264 is indeed very nice to have - even for converting full-sized movies. (Nevertheless, TechRadar's latest roundup (see http://www.techradar.com/news/software/applications/6-of-the-best-video-converte rs-for-mac-1074303 ; also linked from another roundup at http://www.iphonelife.com/blog/87/benchmark-excellent-multimedia-converter-handb rake-vs-commercial-apps ) has shown it's still worse than HandBrake in most respects.)
All H.264 files (assuming they are H.264 level 4.1 or lower) are compatible with the built-in Videos app.
bluztoo wrote:
Those of you who use other players, what do you reccomend? Just curious.
It entirely depends on your needs. The top players (AVPlayerHD / ProPlayer, It's Playing, GoodPlayer) all have different strengths and weaknesses. I myself use It's Playing the most as I convert everything into MP4 and simply love the DSP's (brightness / volume / saturation boosting). (Its software decoders are definitely worse than those of AVPlayerHD / ProPlayer; however, MP4's are played back from hardware.) -

I just installed LR6. I can't seem to move any photos between folders. I drag and drop and nothing happens. No error
To open photos from Photos in Preview use the Media Browser. You do not need to have Photos open to use the photos inPreview.
In Preview use the command "Flle > Open".
The File Chooser dialog will open. Switch the file chooser to columns view and scroll down, until you see the Media section.
Click the Photos view.
Select the Photos app and click the disclosure triangle. -

How do I import music using homeshare with iTunes 11...I can see the shared libraries but I can't drag and drop and there is no import button. Thanks!
Yes, that appears how Mavericks works right now. However, you can open the Address Panel, select all your contacts, then click the To (or CC, or Bcc) buttons to move the selection to the address field.
If it is not already in the Toolbar, right-click on the Toolbar and select Customize Toolbar…
Then, drag the address panel up to wherever you want it.
You may also want to add it to the New Message window in the same way. -

Maybe you should read the manual:

Unable to upload a file with Drag and Drop and http
Hello,
I am trying to upload a file through the web interface (Netscape 4.7 and IE 5.0). When I click un upload, Via Drag and Drop, a new window is started, but never completes.
With Netscape, I get a message box: Netscape is unable to locate the server null. Please check the server name and try again.
With IE 5, I get an error: This page can not be displayed.
Are there any files I need to edit on the PC side to get this to work?

PS I think you guys are doing a great job with support on iFS.WebUI Drag & Drop requires FTP to be running and available.

I need to be able to drag and drop images but I need them to be a certain size when I drag them out of an Aperture project. For various reasons, I don't want to use the export function. Only drag and drop will be efficient for the workflow that I"m planning. Problem is, the pixel dimension is not wide enough when I test it by pulling an image on to the desktop.
My ultimate goal is drag them, sized and ready to go, and drop them onto a web browser upload page. I don't want to fumble with the extra steps of exporting them to another folder on the desktop and then upload the images from that folder to the browser.
So does anybody know how or if it's possible to control the drag and drop SIZE /DIMENSION of an image?The drag and drop size is determined by your preview settings. What actually gets "dragged & dropped" is the preview, not the master file. You can control the quality and size of the preview in the Aperture preferences.

Drag and Drop (and re-order) to ListBox binded to XML
Would you please help me with this scenario:
On stage, 2 listboxes and a textbox.
1.The first listbox lists all the items available, the list is grouped by 'Type' and its source is a binded XML file (read only).
2.The second listbox list all the items the user has dropped into from ListBox#1 and it should read from an XML at start-up and save to it on quitting.
3.The textbox list the details of the currently selected item in ListBox#2
My knowledge (and search on internet ) allowed me to achieve binding, grouping with an expander and perhaps the first step to drag item (to be verified)..but I'm
stucked at dropping AND re-ordering items on ListBox#2..then saving to the XML!!
Would you please help (even in c#..I'll try to do the translation) ? I join a graphic and the project file (with XML files inside) to help you help me! Thanks!!

Thank you very much for your reply...I've followed your advices, read the links you posted...and maked use of ObservableCollection.
So, the listbox source is a CollectionViewSource whose source is an ObservableCOllection object.
Unfortunately I'm still stucked at the drop part. (then there will be the save back to the xml file)
I think that the drag part might be right !?
Could someone please help ??

Drag and Drop and save changes
I am attempting to make an application that gives users a vast selection of icons that they can drag and drop into their own area which act as links to sites once they are double clicked but when they are clicked a single time they bring up a panel which shows the name of the website, a video about the website, a link to the website and a description of the website.
Similar to this example except whenever any of the icons are single clicked they will bring up an information panel or link to the relevant site if they are double clicked:-
http://demo.quietlyscheming.com/DragTile/DragDrop.html
The drag and drop part is easy but I'm basically wondering what would be the best way to achieve this so that all data required is stored 'within' each icon? i.e. how can you store information such as a title and description within an icon so that it only appears once it is clicked and what would be the best possible component to use for the overall icon 'grid' and the icons themselves?
This may sound silly but I've only just started using Flex and I'm simply looking for suggestions.Thanks my friend that helped me a lot and works well.
I have another question for you, if I want to allow the users to SAVE the positions of the links they add how would I go about this? What I mean is if a user drags and drops some icons from a tilelist on the right hand side to their own tilelist in their own profile area how will I allow these tiles to still be saved in the same position if the user closes then reopens the application? I want each user to be abler to create their own list of links and then save these for future uses.
Is there a simple way of achieving this or would it require a vast amount of coding? -
Unable to move ringtone or music by drag and drop and other ways.
Hello,
I recently got a new computer and its Windows 7. I downloaded iTunes, the newest version (11.1.4.62), on 1/31/2014. On my previous computer I had older version of iTunes and was able to simply drag and drop everything.
In this new version I found trouble with adding music but I figured that out. Next I wanted to add a ringtone but I was having trouble. I was able to add the ringtone to itunes-Library-Tones (format m4r) but after this I am unable to add it to devices-tones. I tried drag and drop, I tried sync and it simply wont work. If i try to drag and drop a song straight to my devices it wont allow that either. I am even unable to delete any songs that I have on my iphone through iTunes. I also had voice memos on m phone and I cant even edit that section or voice memos.
Someone please help! this is very frustrating that I can't remove, add, edit my iphone through iTunes.After Effects CS4 is not supported on that version of Mac OS. See the system requirements for After Effects CS4:

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.
NikIf you haven't already read these, here are a couple of good sources for DND tree implementation details.
