Calling NativeDragManager.acceptDrop when drag over an html control

Hi,
I'm using AIR and I want to change the mouse cursor to show an "accept" or copy cursor during a drag operation. I am dragging a file from outside the application over a html control (mx.controls.HTML)
In the NativeDragEvent.NATIVE_DRAG_OVER event handler I tried to call NativeDragManager.acceptDragDrop(event.target) but the NativeDragEvent.target is a FlexHTMLLoader object.
This type is incompatible with the expected argument type InterActiveObject.
I haven't figured out how to get the cursor to change. Any ideas?
Claire

HTML uses the Webkit drag-and-drop API. See http://help.adobe.com/en_US/as3/dev/WSC982AEFA-D020-41aa-8C3D-37AAEB7C132C.html.

    My CS3/PS has started to change the cursor into a line of three VERY small icons when dragged over a picture or menu. Thus it is VERY difficult for instance to drag a layer in the layer list to the wastebasket - the cursor simply is too big for the waistebasket icon. Even all other exact work is impossible.  Of course I have checked all the cursor presets but nothing seems to help. My OS is Windows7.

    Have you tried resetting Preferences?
    A logical next step would be to reset your Preferences.
    To reset Preferences:
    If Photoshop is already open on your screen, close it (Quit). Then hold down Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and start Photoshop.
    A dialog box will pop up asking if you want to delete the existing Preferences file (the "Settings"). Click Yes in the dialog box. The existing Preferences file will be scrapped and a new one will be created.

  • I am trying to create a group in the address book.  When I drag over the contacts from the contact list they duplicate in the address book. I am using "Lion"

    When I try to create a group from the address book, when I drag over the names from the contact list, the names duplicate in the address book.

    Hi cavu10horses,
    Thanks for using Apple Support Communities.  This article has instructions for changing a contact's photo using a photo from iPhoto's Faces feature:
    Contacts: Add or change contact pictures
    http://support.apple.com/kb/PH11580
    Select a contact or your own card, and then double-click the picture well.
    Select a picture:
    Drag an image to the picture well.
    Click Camera to take a picture.
    If you have pictures in iPhoto, click the Faces button to use a face from iPhoto.
    If the contact is linked (it’s in multiple accounts, but displayed only once in Contacts) and has multiple account pictures, click Linked.
    Click Edit to edit the picture.
    To zoom in and out of the picture, drag the slider. Drag the picture to change which part of it is visible.
    To rotate the picture, hold down the Option key while you click and drag the picture.
    To apply special effects, click the Effects Gallery button and choose an effect.
    Click Done.
    Cheers,

  • Problem loading flv over network when accessing swf through html

    hi all,
    i have website that loads images and videos for my company.
    it's an internal thing that's meant to be shown in a network folder
    that people can access.
    my problem comes when i try to load videos in. on my local
    machine, everything works fine, if you launch the swf directly from
    the network folder, everything works fine. the problem comes when
    you launch the html that the swf is embedded in. my netconnection
    is successful, but when i try to load the flv using netStream.play
    (using a local path like "videos/myVid.flv") if get a
    NetStream.Play.StreamNotFound error.
    local paths work fine when loading images etc but not videos
    (even when i put the video into the images folder or vice versa).
    the only way i can get this working is if i put absolute paths into
    the video ( like "\\myServer\flash\videos\myVid.flv")
    i'm thinking this is a sandbox problem. when you open the swf
    directly, it's running on the network, so it's ok to access network
    files, but when you open the html, it's being loaded to your local
    computer, and isn't able to do it? both times when i print out the
    sandbox type it's "localWithFile", but it just doesn't work in the
    browser. but then i don't get why xml loading and image loading
    works, but not video. i've also changed the export to
    localWithNetworking and tried Security.allowDomain("*") but nothing
    worked.
    this works fine if the files are uploaded to a webserver,
    btw.
    i've
    put
    up a zip file with the relevant files (though you'll have to
    stick in your own flv), though unless you have a network handy it's
    going to be a bit hard to test it.
    any help or points in the right direction would be
    appreciated though
    thanks

    Your files work fine with my FLV and when I try to follow
    your instructions. Two days ago we had a situation that was almost
    like what you've described, except that the swf would work, the
    html work work (when opened directly, like
    "file:///Users/colin/Desktop/video%20bug/video_bug.html", but would
    not work when opened via http. If that is your real situation then
    you may have the same issue we had, which is that our server had
    its MIME type set wrong for handling FLVs.

  • How do I stop text from changing colour when hovering over it?

    Hello, I have downloaded a template for Dream Weaver CS6 (Which is the version i am usig). When you hover over one of the boxes the top text changes colour to black instead of staying white... does any one know how i can make it so the text stays the same colour. I will post a print screen of it.
    Before clicking:
    View image: 1
    When hovering over it:
    http://postimg.org/image/wdsii9mab/
    I will post the code of the index page aswell: <!DOCTYPE html> <html lang="en"> <head> <title>Home</title> <meta ch - Pastebin.com
    Any help is appreciated. Thanks.

  • I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build.  The same call works fine when running on the device

    I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
    I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
    The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
    I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
    I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
    By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
    Anyone have an idea on other things to try to debug/resolve this?
    Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
    Thanks!

    After a week's worth of debugging, I found the issue.
    The Java type returned from the call was defined as ArrayList.  Changing it to List resolved the problem.
    I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid.  And, why it works in Debug mode and not in Release build is even stranger.  Maybe someone can shed some light on the logic here to me.

  • Why, since CS6 does DW now use ABSOLUTE image paths when dragging images into Design View from a folder in Finder?!

    While I am grateful the previous issue I had with not being able to drag files into design view at all (in CC and CC2014) was resolved.
    Guys (Adobe), seriously, if you're going to change the functioning of something that used to work just fine, at least supply a way for a user to revert to the old way... I absolutely loathe that I need a legacy version of DW to continue with my current workflow. Please put it back to the way it was, or at least allow a user to chose between the two behaviours.
    If there is a way to do this, without using the Site Manager (which still doesn't work from Finder even with relative to document selected), I would appreciate any guidance.
    As for using the Site Manager (before some smart guy suggests that I just use that) I do not wish to navigate to and create up to 20 "sites" a week and wait for DW to cache them all, when I am already in the folder with the image assets in Finder.
    Also before someone pipes up and says: "You shouldn't be diving sites in design view anyway", I don't... I develop many, many newsletters every week and the folder structure is such that navigation to the actual image folder using the Site Manager would be painful at best.
    I don't really like having to and replace all instances of "file:///Users/me/Work/company/Mailers/Year/wk14/mailer/dev/img/prod5.jpg". It is horrendously wasteful, time-wise.
    Thanks in advance for any helpful replies

    Sorry Murray, DW used to have an idea, my point is that since CS6 its developed a case of Amnesia.
    The "elements" are in the "root" folder as follows:
    newslettername.htm
    img
         imagename.jpg
    So the relative path would be <img src"img/imagename.jpg" />
    However since the change: <img src"file:///Users/me/work/Company/year/week/campaign/img/imagename.jpg" />
    Which is completely useless and needs to be corrected before I upload the html anywhere.
    As for using the site directory, I did answer that in my initial post. I use a laptop, I really don't want a site manager taking half my screen just so I can see the folder structure and navigate with that, especially since I am already at the files I need in Finder.
    Again, this is something that used to work just fine in previous iterations of DW, so I don't believe Adobe is incapable of fixing it nor am I being unreasonable asking for a choice for those that may find the local absolute paths useful in some way. All I want is to be able to chose not to use absolute paths when dragging from Finder.

  • App not working properly when access over vpn

    hi,
    Strange behavior of application when access through vpn. The application keeps on reloading endlessly. And other application renders completely but when the tab is clicked it will reload the whole page displaying the same tab. Is ADF has an issue when access over proxy?
    Both application is build using ADF 11g and is implemented through regions.
    Thanks in advance.

    I think there something to do with PPR or calling the region or am I missing something? The page that keeps reloading has taskflow with activation is immediate but the refresh is set to IfNeeded. Then the page with tabs, the content of the tab are taskflows as well.
    Thanks in advance.

  • No display when dragging regions

    normally, when dragging audio and midi regions in the arrangement window, a transparent copy of the selected region appears right when you left click and hold, and this copy follows the mouse icon so you can see exactly where you're moving it before you let go of the left click.
    my copy isnt showing up at all, so when click, hold, and drag, i don't see anything except the mouse icon. so i don't know where i'm dragging the regions to until after it's there. i must have accidentally turned the display off somehow. how do i fix this?

    Greetings Troy,
    Are you getting the startup chime *bong* and / or do you feel air coming out the ventalation port so you know it is powering on at all?
    Reset the SMC and then test: http://support.apple.com/kb/HT3964
    Reset the PRAM and then test: http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html
    Remove any RAM that you may have installed after you bought the computer and put in the original memory (if applicable) and test.
    Try a different wall outlet for the computer, one that is currently working fine for another electrical device.
    If the issue persists after you follow the above steps, you may wish to make an appointment with a Mac Genius at an Apple store, contact AppleCare via phone, or contact an Apple Authorized Service Provider for assistance.
    Best of luck to you.

  • Linked images "jump" when rolled over

    When rolling over an image being viewed on a page in IE/Mozilla, it seems to "jump" if it is linked to a larger version of the same image.  Am guessing it is a setting in Page Properties, but I believe I've changed just about everything with no luck.

  • Call JavaScript function when my Condition is true in JSP

    Hi all,
    in my jsp i wanna call a javascript function (user defined) when a particular condition si met. How to go about it ? Can anyone plz help me out. Help appreciated.

    hi
    yes! we can do it as follows:
    in the JSP code u can include the javascript function
    first u declare the Javascript function before the </head> tag in the HTML
    and in the JSP u can just call the function which is as follow:
    <script>call the JavaScript function()</script>
    for example:
    <html>
    <head>
    <script language="JavaScript">
    function sayhi() {
    alert("hi");
    </script>
    </head>
    <body>
    <%
    zStr = request.getParameter("str");
    if(zStr.equals("true")) {
    %>
    <script>sayhi();</script>
    <%
    else {
    %>
    </body>

  • [AIR] Drag Problem (parent & children can receive d&d and HTML Control)

    Hi,
    I have a problem regarding drag and drop in AIR. The d&d involving parent & children that can receive d&d event and the children can contain HTML control. You might want to copy and paste the code below to get a better idea.
    The objectives are:
    1. If you drag the green object and drop it in the black area, it should alert "Parent Drop"
    2. If you drag the green object and drop it in the magenta (purple) color, it should alert "Child Drop"
    3. If you drag the green object and drop it in the white (HTML control) color, it should alert "HTML Drop"
    The problems:
    1. drag green object to black area, to magenta area, and back again to black area. Drop it, the alert is not shown
    2. drag green object to the white area (HTML control). Drop it, the alert is not shown
    Many thanks.

    The parent drop issue is because there can only be one drag acceptor and you don't get another dragEnter event when the mouse leaves the child (since technically, it never left the parent). This isn't as big an issue as it might seem, since generally you wouldn't have both a parent and a child that could take the drop. The ways to fix this are to use the dragOver event in addition to dragEnter or you could handle the dragExit event dispatched by the child and set the drag acceptor back to the parent.
    The HTML control issue is a bit trickier. HTML content has its own drag-and-drop system that operates a bit differently than the ActionScript version. I don't think there is a way to intercept the events before they are handled by the WebKit HTML engine. You can accept a drop in HTML/JavaScript code as described here: http://help.adobe.com/en_US/as3/dev/WS6717AA0A-2B7D-4728-86DC-7D60F919E6B4.html.

  • Error when dragging a contact from Address Book to iCal

    When I first got my Mac, I used to be able to drag over a contact from my Address Book into iCal, and it would create a meeting no problem. Now when I try the same thing all of a sudden I get an error saying:-
    "There was an error with the invitation.
    Only the organiser can change this event. Contact
    the organiser to make changes."
    I have spend ages trying to sort out the problem but to no avail.
    I have made sure that I am in the address book with my correct email address and that it is to "me", but still the error
    Please can anybody help with this?

  • How can I find the node I am dragging over during MouseDragged ?

    It seems that while dragging you only get MouseDragged events on the node where the drag originated. I have a situation where a drag starts on one node and ends on another.. I am having a lot of trouble finding a reasonable way to get the node where the drag leads to.
    E.g. imagine a UI where I am dragging a "connection" from one node to another. I can't use Drag and Drop (which otherwise would report DragEntered andDragExited events), because during a Drag and Drop I don't get any MouseMoved or MouseDragged events, so I can't draw my connection line interactively.
    I was hoping I could get MouseEntered and Exited events somehow during the MouseDrag, but they aren't delivered, and even attaching an EventFilter to the nodes in question didn't work. During the drag all events are reported on the listener registed with the source of the drag, but in the drag event even the event Target is set to the same value as the event Source, regardless of what the mouse is dragged over during the operation.
    If there is no way to get the need events, is there a built-in way to get the "deepest" node in a scene given the scene coordinates?
    Thanks,
    Scott

    Thanks for the response.
    I really think that having target nodes involved with the press-drag-release gesture is important. It seems broken the way it is now. As soon as a drag of any sort begins (MouseDragged, or Drag-and-Drop) suddenly a lot of useful information is unavailable. Why not set the target of the MouseDragged event to what the mouse is actually over? Currently, one the drag is initiated the source and target are fixed forever and no other events are available to find what the mouse is hovering over. (Hmm.. I should check if even the "hover" state is changed on components,as I want my CSS to indicate that a node is the intended destination of the connection that I'm dragging)
    The other ugly bit is that now I have to get other objects involved in the operation, whereas before I could just attach event handlers to my nodes, now I need to have a parent involved just so I can see where the mouse is going. I also need to deal with the mouse cursor, which will be giving the user bad feedback, that a drag and drop is happening, when that's not really the concept that I want to convey.

  • My phone sounds like its breaking up when I call. Then when the other person answers all I hear is my voice echoing and all they hear is static

    My phone sounds like its breaking up when I call.
    Then when the other person answers all I hear is my voice echoing and all they hear is static
    Same happens when they call me.
    Data over the phone - to Vodaphone - is fine. I can browse. With or without wifi.
    My speaker and mic work fine.

    I think the fault just developed out of the blue. I called somebody left the phone on the table downstairs the person tried to call me back 11 times and I never heard them. When I tried to call later in the day the phone had an error.
    When try to phone my iPhone from the land line the ring tone is perfect but I get the same problem with my iphone just echoing my voice and nothing else - and the landline having loud static and nothing else.
