问题 Moving a node ( Label in this case) within its parent Pane (lets call it moving), works as expected by adding appropriate handlers for MouseEvent : node.setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { x = node.getLayoutX() - mouseEvent.getSceneX(); y = node.getLayoutY() - mouseEvent.getSceneY(); } }); node.setOnMouseDragged(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { node.setLayoutX(mouseEvent

问题 It is very important that I can track which item is dragged in UWP TreeView and onto which item it is dropped. For now, I can get only item that is dragged. But I can not detect over which item it is dragged over or over which item it is dropped. Also it would be also good to know as preview which item is dropped onto so I can do more actions (for example cancel dropping on certain items). Here is my extended control: public class MyTreeView : TreeView { public MyTreeView() { this

问题 In Java, JTable by default does not offer the functionality to drag JTable rows for reordering the table.

问题 I have a program I'm working on that takes input names and creates JLabels and populates them into an ArrayList. When the user clicks the Begin button, the JLabels populate in the left JPanel. What I've been trying to do it use DnD to allow the user to drag and re-order the labels in the left panel. So far, I've only been able to get it to copy the text from one label to another. My goal is to drag a label up or down in the list, and depending on where it's dropped in the JPanel, have the

问题 After consecutive drag and drop in mxgraph, the parentInfo is lost for cell. Children and Parents for cell are not getting updated after consecutive drag and drop. Drag and Drop is handled using connect, the logic behind is simple. Removing the existing parent connection and establishing new edge connection with target node. mxConnectionHandler.prototype.connect = function( source, target, evt, dropTarget ) { var sourceParentCell = getParentCell(source); if (sourceParentCell !== target) {
