Question for YUI experts... I have a table and I've made each cell of the first row draggable by proxy. In IE, when the drag proxy is released, the original table cell actually jumps to wherever the release point was. How can I prevent this from happening? Essentially, I want to know where the proxy was dropped and handle my logic from ...
I've asked this question to the forums on the Mootools website and one person said that my class selection was corrupted before an admin came along and changed my post status to invalid. Needless to say this did not help much. I then posted to a google group for mootools with no response. My question is why doesn't the 'enter', 'leave...
Once I've called DragManager.acceptDrag is there any way to "unaccept" the drag? Say that I have a view which can accept drag and drop, but only in certain areas. Once the user drags over one of these areas I call DragManager.acceptDrag(this) (from a DragEvent.DRAG_OVER handler), but if the user then moves out of this area I'd like to ch...
I'm a bit perplexed by drag and drop in wxPython (but perhaps this questions pertains to drag and drop in other GUI frameworks as well). The frameworks provides a couple of callbacks (OnEnter and OnDragOver) that purportedly allow me to inform the system whether the current mouse position is a valid place to drop whatever it is that is b...
Is there an easy way to ensure that after a drag-and-drop fails to complete, the MouseUp event isn't eaten up and ignored by the framework? I have found a blog post describing one mechanism, but it involves a good deal of manual bookkeeping, including status flags, MouseMove events, manual "mouse leave" checking, etc. all of which I wou...
I need to create a quick-n-dirty knob control in Visual Basic 2005 Express, the value of which is incremented/decremented by "grabbing" it with the mouse and moving the cursor up/down. Because the knob itself doesn't move, I need to keep tracking the mouse movement outside of the rectangle of the control. I use a Label with an ImageList...
We are currently using the ExtJS tree view in an application - a requirement has arisen requiring a user to select multiple nodes (which the tree view supports currently through a pluggable selection model) - but you can not then drag the multiple selections to another part of the tree. Does anyone know of an ajax control (commercial or...

I've seen this done in Borland's Turbo C++ environment, but I'm not sure how to go about it for a C# app I'm working on. Are there best practices or gotchas to look out for? ...
I have three unordered lists that have been created as Scriptaculous Sortables so that the user can drag items within the lists and also between them: var lists = ["pageitems","rowitems","columnitems"]; Sortable.create("pageitems", { dropOnEmpty: true, containment: lists, constraint: false }); Sortable.create("rowitems", { dropO...
Ever wanted to have an HTML drag and drop sortable table in which you could sort both rows and columns? I know it's something i'd die for. There's a lot of sortable lists going around but finding a sortable table seems to be impossible to find. I know that you can get pretty close with the tools that script.aculo.us provides but i ran ...

I have a Windows/Linux Qt 4.3 application that uses drag and drop in a QTreeView. I have two very similar applications which use the same set of Qt libraries. Drag and drop works in both on Linux but in only in one on Windows. In the application that does not work the QDrag object gets deleted as soon as the mouse is moved. I...
If I drag and drop a selection of a webpage from Firefox to HTML-Kit, HTML-Kit asks me whether I want to paste as text or HTML. If I select "text," I get this: Version:0.9 StartHTML:00000147 EndHTML:00000516 StartFragment:00000181 EndFragment:00000480 SourceURL:http://en.wikipedia.org/wiki/Herodotus <html><body> <!--StartFragment-->Addi...
I would like to drag and drop my data file onto a Python script and have it process the file and generate output. The Python script accepts the name of the data file as a command-line parameter, but Windows Explorer doesn't allow the script to be a drop target. Is there some kind of configuration that needs to be done somewhere for this...

I'm working with jQuery UI's droppables and am wondering what the best way to make the dropped clone use a different IMG SRC than the item being dropped. In the photo manager demo there, the thumbnail gets dropped into a slot that's the same size. I'd like to drop a large image into a small slot, and as such I need its clone to use my t...
I'm using the Scriptaculous library to slap an appealing UI on an application which helps an enduser build lists. Let's say its for pizza creation. To fill out an order, you drag a size of pizza from the pizza palette into the orders droppable. Once it is put in there, it gets replaced with a new div which is both draggable (because y...
I have a pure Winapi application that needs a few new features. One of them would best be implemented as two lists where you can drag-and-drop (multiple) elements between the lists. The new feature can be limited to a single dialog. What would be the quickest way to implement this? A few ideas: Pure Winapi (is it DetectDrag) A separat...
I have a TListBox with multiselect and ExtendedSelect both set to true. I need to be able to drag multiple items in the list box to re-arrange them. My problem is what happens when the user clicks on an item that is already selected without holding down the CTRL or SHIFT key. Case 1: DragMode is set to dmManual The selection is cleared...
