drag-and-drop | Simple drag and drop for SwiftUI | Widget library

I was using Python 3.9, Django 3.2.8, and Django-admin-sortable2 1.0.3. I was facing issue that my custom order field (I named it "sort_order") was visible in inline tabular forms but it should have been hidden as per Django-admin-sortable2 implementation. And although I was able to drag-and-drop items, but upon saving the parent object, the sort order wasn't getting saved.

My admin classes were as follows:

Im working with Tkinter currently and im trying to make an draggable canvas image, the code i've "made"/edited from another stack overflow question, the second one to be particular. There code works for me when im using tk.Frame(), but it gives an error for Canvas.create_image(). So i edited it a little but now it seems to to be moving the image at all when i drag it

My code:

So, I've been warned that some of my past questions have not been well-received, and I'm in danger of being blocked from asking any more. I hope that this question is well-received and that it doesn't result in me being blocked from asking more questions! I'll do my very best to formulate it as a clear and useful question.

What I'm trying to do is create javascript to click-and-drag images into nested lists. I've read HTML Drag and Drop between multiple Unordered Lists and How to drag and drop into an html unordered list, and neither addresses what I'm trying to do.

The images I want to click-and-drag represent items--some items can contain other items while others cannot. For instance, a Single-Barrel Shotgun can contain Shotgun Ammo, but Shotgun Ammo cannot contain anything.

I've created a jsfiddle, https://jsfiddle.net/pjamesnorris25/9f0y8edz/76/, to facilitate some javascript wizard helping me with this. And because I have, I'm not going to post the javascript here unless someone asks me to do so.

My javascript works if you click-and-drag the shotgun to the "Left Shoulder" in the image of the generic person below the "Shotgun Ammo" and "Single-Barrel Shotgun" images in the upper right-hand corner. That is, when you do so, the text "Single Barrel Shotgun" appears below the "Left Shoulder" in a of its own denoted by a box around the text--the box indicates that "Single Barrel Shotgun" is a container into which you can drag other items, in this case, "Shotgun Ammo".

Prior to dragging the "Single-Barrel Shotgun" graphic to the "Left Shoulder" container, my HTML looks like this:

I am working on (py)gtk4's drag-and-drop functionality and I hit a wall. I have a flowbox-derived class MediaGallery that contains frames with images and their filenames (class MediaFile), and a listbox-derived class Albums. I want to drag one or more selected images from MediaGallery to Albums, which will eventually add them to the underlying database.

Relevant piece of code:

I'm trying to implement a simple drag and drop of a String from ViewA to ViewB, on a macOS SwiftUI app, but my NSItemProvider.loadObject(ofClass:completionHandler:) always fails with the error "Could not coerce an item to class NSString".

I am new to Java and I would like to create a very simple draw-GUI, in which the user draws simple forms clicking on the panel and connecting different spots with a line when mouse is pressed in a position and released in another (drag-and-drop). Spots and lines should be stored in two ArrayLists. I managed to get the spots on the panel when clicked but the line is changing coordinates every time the mouse is dropped and a further point is created. I tried many times but I don´t know how to make the lines remain on the panel and "trace" the drag-and-drop-activity.

Thank you in advance for every tip!

I'm having a todo-list made with React. It is having 3 section:- "Todo", "In Progress" and "Done". I've implemented drag-and-drop functionality to this list. It works pretty fine. But, after the drag-and-drop, the state is not updating. How can I update the state after the drop?

Functionality:

I am very new to react.js (and somewhat new to javascript) so apologies in advance.

I am looking at this example here:

https://reactflow.dev/examples/drag-and-drop/

I believe that matches up to the git repo here:

https://github.com/wbkd/react-flow/tree/main/example/src/DragNDrop

I would like to modify the code so instead of the text being "input", "default", "output", I would like it to be "alpha", "beta" "gamma".

I realize I should be able to set the label as shown in line 19 here:

https://github.com/wbkd/react-flow/blob/main/example/src/DragNDrop/index.tsx

However, in the onDragStart method shown here: https://github.com/wbkd/react-flow/blob/main/example/src/DragNDrop/Sidebar.tsx

They call a event.dataTransfer.setData('application/reactflow', nodeType); . I'm not quite sure how to change hat to set the "label".

Any help would be much appreciated, especially for a beginner in react. Thanks!

I want to run the example from the official Vaadin vendor site: https://vaadin.com/components/vaadin-grid/java-examples/drag-and-drop Of course, I have some other objects to drag, but i am happy when the example is working. At the minute, I don't know how it is meant to be used, or I am getting dumb, because I am living in germany.

I wonder why the example is not running out of the box. When i use this code, there are several errors in the code. What is dragItems? And how to calculate the index of the drop position? Any help is appreciated. I just want to use this framework, but the demos are not compiling.

I want to drag an item from a grid on another grid. How to do that?
