I need to implement a grid in WPF which has squares that can be dragged/dropped to be re-ordered, but I'm not sure the best way to do it. I was thinking using an ObservableCollection of squares and a UniFormGrid but although I have experience with both WPF and drag/drop, ideally I'd like to do a kind of 'jiggle' when before the user rele...
I'm working on a web app where I support dragging on the page, by simply watching for mousedown/mousemove/mouseup events. That part works great. The problem is that I'm only handling dragging inside one particular element, by design, and if a user (accidentally or not) drags outside, it gets "stuck" in drag mode. That is, mouse-down, ...

I have a problem when the table with the draggable rows is inside an iframe. When I drag a row and take it to the top, the page will not scroll (even after explicitly setting scrollAmount to a p...

However the items now are arranged on arbitrary manner. Is a mess really. They stay where the user left them. What I need now is to make them to be st...

Choice nodes present a set of choices for the user to select from. The user should be able to easily "link" a choice in a "choice node" to another node. Desc of frontend: When being...
Suppose I want my draggable widget to move differently than just staying under my cursor while being dragged. For instance, having the widget move only in one axis, or have the widget move double the distance between the cursor and the drag starting point. Which method should I override to define this kind of behaviour? ...
I am just wondering if it's possible to I cancel "Drag and Drop" operation in Java/Swing programmatically? So the effect would be similar to if the user pressed the "ESC" key? I was expecting DragSourceDragEvent or DragSourceContext to have a cancelDrag() method, similar to DropTargetDragEvent which has acceptDrag() and rejectDrag() met...

I need to create a drag and drop system in swing where an image of the thing being dragged is attached to the cursor during the drag. In theory this is achieveable with public Icon TransferHandler.getVisualRepresentation(Transferable t) but there appears to be a long standing bug (here) that means this method is never called. I know ...
I've read through many of the drag and drop threads on SO and i haven't found one that tells me how to get the child element id of the dragged element, when the dragged element is dropped. For example if you have <div id='drag'> <img id="something"/>//how do i get this id when #drag is dropped? </div> <div id='drop'> </div> and t...

I am trying to add drag-and-drop text to my Doc-View App. I added the COleDropTarget variable to the view class, registered it in OnCreate(). I added OnDragEnter(), OnDragOver(), OnDragLeave() and OnDrop() to that class as virtual overrides, but none of them are ever called. I previously had added m_pMainWnd->DragAcceptFiles(TRUE); to my...
How does one determine the (x,y) coordinates while dragging "dragover" and after the drop ("drop") in HTML5 DnD? I found a webpage that describes x,y for dragover (look at e.offsetX and e.layerX to see if set for various browsers but for the life of me they ARE NOT set). What do you use for the drop(e) function to find out WHERE in the...

After creating a div on the fly with this markup: $('.circuit').prepend("<div class='component' draggable='true'>TRANSISTOR</div>"); It is NOT draggable itself :( Is jQuery prepend() the correct way to create "live" tags in the DOM? Do I need to somehow bless it a different way to make draggable=true really work? How to I wire it u...
Hi, I need to know how to detect the position of a dragged item as opposed to other divs. I need to detect whether an item is dropped outside of two different divs. (I am building a mac dock type start page and I need to know how to do this so I can delete icons by dragging them off the bar.) Any help would be greatly appreciated. ...
