draggable

问题 While this should be relatively straightforward, I can't figure out how to move (rather than copy) LI elements between UL s. All I want is to drag any item from list foo to list bar (or vice versa) without duplicating the element. While connectToSortable does almost exactly what I want (though I'd prefer to avoid sortable ), it clones the element - and manually removing the original element by reacting to the stop event turns out to be not so easy (e.g. ensuring that a valid drop actually

问题 We have a requirement in which we need to hide the header of the window and for this we are using header:false But if we use header:false, then window can not be dragged at all. Thus, is there anyway by which a window can be made draggable by body? That is, if header is set to false and is not getting displayed then also somehow user can drag the window. Any suggestions anyone. Thanks for the help. PS: ExtJS Version 4.1 回答1: You could create your own window class that changes how the dragging

问题 Consider a stack of widgets as shown in the image. We can see that index 0 widget is attached with index 1, 2, 3, 4 widgets; ...; index 3 widget is attached with index 4 widget and index 4 widget is not attached with anyone. Now when I drag a widget, all the attached widget should also be dragged with it i.e. if I try to drag the index 2 widget, the dragged widgets should be the stack of index 2, 3, 4 widgets. if I try to drag the index 4 widget, the dragged widget should be only the index 4

问题 So I saw the ReorderableListView demo and saw that they had the "secondary: const Icon(Icons.drag_handle)" but looking at the reorderable_list.dart file, I noticed that the entire list was draggable on LongPressDraggable anyway [line 424]. So how can I explicitly make changes to either the source code or my own, in order to properly make the icon an actual drag handle? CheckboxListTile( key: Key(item.value), isThreeLine: true, value: item.checkState ?? false, onChanged: (bool newValue) {

问题 I got a container with unknown nested elements and I would like to move a selected child target around using js + transform translation. The problem I have is that a parent element can be scaled so the selected target moves faster/slower depending on the scale. And rotation makes it also harder to move it in the direction of the mouse movement. How should I go about solving this problem? My assumption is that I need to walk up the DOM tree and combine all the matrixes and add, subtract values

问题 The AnimatedIcon widget, when holding/dragging it, teleports to the top-left hand of the screen(not intentional). It initially starts at the centre of the screen and returns to same position when it is released. Any help would be greatly appreciated. Note: As this is in GIF format, it does not appear smooth here. Here's my code: import 'package:flutter/material.dart'; import 'package:flutter/services.dart'; void main() { runApp(MyApp()); } class MyApp extends StatefulWidget { @override

问题 After following the instructions in the link here How to create draggable pin in windows 10 to give pick location functionality? I have a half working dragging pin. Currently the map pin (Grid) starts in the correct place on the map, however, upon dragging the map pin the pin initially pops up to the top left of the screen (0,0) and starts dragging from here. Upon dropping the pin it appears to have disconnected from the map element itself as you can then scroll the map and the pin stays in
