drag-and-drop

问题 I have defined a custom canvas style component, using JPanel, that will support the dragging of objects onto the canvas. What I can't seem to figure out is how to change the drag and drop (DnD) cursor to a custom one, using a TransferHandler. For example, instead of the default link cursor during DnD, I want substitute my own. Is there a way to do this using a TransferHandler? I suspect I will have to use the AWT DnD support to do this but I am hoping to avoid that if I can. 回答1: By digging

问题 I have associated a file extension with my Delphi 2009 program. I have been using the command line call method to pass the filename to my Delphi program so it can be opened. However, I found that when selecting multiple files, and clicking on them all at once, it opens each file in a separate instance of my program. I asked about this, and apparently the solution is to use one of the other two Windows methods: DDE or IDropTarget. But DDE is being deprecated, and MSDN recommends the

问题 I would like to prevent a user dragging certain items from one TileList to another. Whether or not they can be dropped into the TileList should be determined based on data associated with the item. To show that the item cannot be dragged into the TileList I would like to show the normal white cross in red circle icon next to the cursor. If a drop is attempted when it has been determined that drop should not occur I would like to show an alert message explaining why this item could not be

I've applied scrolling/dragging logic in this app using MOUSE_MOVE event handler.

My problem is dragging is quite jerky/shaky. Any suggestion would be

问题 I'm building a single page which consists of a list (of div's) on the left and a grid (of div's) on the right. I would like to add the ability for a user to click and drag one of the list items and drop it over one of the grid boxes. I'm not using HTML5, but I know it comes with this native capability. I'm trying to avoid HTML 5 at the moment. The above illustration shows my basic page layout and the red line shows how things will be dragged/dropped. Any of the list items may be dragged into

问题 Is there any way to Drag and drop from javaFX scene to windows explorer? 回答1: Yes there is You should use the onDragDetected function to start your dragEvent and the onDragDone function for doing whatever you want after finishing the drag & drop. Here an example: final Text source = new Text(50, 100, "DRAG ME"); source.setOnDragDetected(new EventHandler <MouseEvent>() { public void handle(MouseEvent event) { /* drag was detected, start drag-and-drop gesture*/ System.out.println(

问题 I have a Protractor/Jasmine E2E Automation test that is to drag and drop a couple of collapsible panels to change the order and just verify they the elements have been moved. I'm currently running latest versions of Protractor, Jasmine, and webdrivers (tests run in IE 11) EDIT: Found out we're using ng-dragula to perform the drag and drops. I'm assuming protractor just isn't playing nicely with this. I'll do more digging about it, but still curious to know if there's a work around. /end edit
