drag-and-drop

问题 I'm trying to achieve a reorder-able group of list which contain elements that can be moved between lists, using @angular/cdk/drag-drop, although I'm running into a few problems. I've managed to separately create individual examples which achieve the individual drag and drop, although when brought together it seems I cannot achieve both pieces of functionality in parallel.

问题 I need to set up a Highcharts chart of type "organization" which should support Drag & Drop the Nodes on each other (to move the nodes inside the tree). Currently, I got an "organization" chart which displays all the needed information. I tried to use the Highcharts.plotOptions.series.dragDrop -Events but that wasn't working at all. I also tried to use Highcharts.series[organization].dataLabels.nodeFormatter -Callback to replace the outer div by a div with attributes: draggable="true"

问题 I have a QTableView and I'd like to be able to drop an image file from outside the application onto a row and upon this event it needs to identify which row it was dropped on, do things with the file (copy to a directory, resize, add to db, ...) and finally update a column in the table that this item/row now has an image file associated to it. I've figured out that I can inherit from e.g. QTableView, re-implement dropEvent(QDropEvent*), I could then call QDropEvent::pos() inside the member

问题 After having started a Drag & Drop operation by DragDrop.DoDragDrop(...) no more MouseMove Events are fired. I even tried AddHandler(Window.MouseMoveEvent, new MouseEventHandler(myControl_MouseMove), true); where the last parameter means I even opt in for handled events. No chance, seems like the MouseMove Event is never fired at all! Any way to still get MouseMove Events while using Drag & Drop? I'd like to Drag & Drop a control, while dragging this control it shall follow the mouse pointer.

问题 I'm using JQuery UI draggable option to drag and drop components to content editable paragraph.My code as follows, My code as follows: $(function() { function textWrapper(str, sp, btn) { if (sp == undefined) { sp = [0, 0]; } var txt = ""; if (btn) { txt = "<span class='w b'>" + str + "</span>"; } else { txt = "<span class='w'>" + str + "</span>"; } if (sp[0]) { txt = " " + txt; } if (sp[1]) { txt = txt + " "; } return txt; } function chunkWords(p) { var words = p.split(" "); words[0] =

问题 I want to copy an item from a QTreeWidget -parent under another parent via a drag & drop mouse operation. For this, I have implemented the dropEvent() and am setting the dropAction to Qt.CopyAction . But anyway, the item I am dropping is not being copied under the new parent. E.g. -> dragging the user "schmidt" under the group "LON". Expected behaviour: the item I am dropping is being copied under the new parent. (e.g. user "schmidt" will be added under group "LON").

问题 I am using simple HTML-5, and using Drag n Drop feature in React JS, without any library. I have implemented on web, it's working good but when i come to mobile it doesn't work. There are touch events to handle touch things for mobile but i am not achieve any solution. Please recommend some thing which works well. 回答1: There are few shim libs that emulate HTML5 drag and drop on mobile devices. Example: DragDropTouch They usually clone element that you try to drag on touchstart , copy all
