drag-and-drop

问题 I'am looking for a pretty and easy way to use HTML5 Tags inside of my Adf Faces Application. I'am using ADF 12c and it's supposed to support HTML5 and CSS3. Until now i get this <f:facet name="center"> <af:inputText label="Label 1" id="it1" placeholder="Test"/> </f:facet> placeholder is an HTML5 feature. My questions: How can i use something as Canvas or Drag and Drop Events ? 回答1: You can use canvas tags directly, you can use normal HTML tags with ADF Faces 12c, and you can inject EL

问题 This is my first time encountering with such an object. >Link of image of my local window during debug< So to put it very simply, how do I access the value for CardNO or ItemID, which is 296 and 130 respectively when the only methods 'test' give are exactly like a normal object and I don't know what to cast it to. I can't even do this 'test[0]'. This is where 'test' comes from: private void ListBoxIssue_OnDragEnter(object sender, DragEventArgs e) { var test = DragDropPayloadManager

问题 I've added this listener to a JLabel, and I am able to drag the image around perfectly, However, as soon as I click on the panel(in an area where a JLabel is not present) the label returns back to it's original location.

Thanks! public class CardLabelListener extends MouseAdapter { private MouseEvent initiateEvent = null; @Override public void mouseReleased(MouseEvent me) { System.err.println(

问题 I'm using angular-dragdrop.js (http://codef0rmer.github.io/angular-dragdrop/#/) It works nicely on Chrome but generates error at drop in IE. (drag an item from a list and drop it to another list) I have a requirement that the app needs to work in IE8. I saw the error in console, apparently it is complaining about $timeout in the angular drag drop code: $timeout(function(){this.mutateDraggable(v,u,o,i,s,l,e);this.mutateDroppable(d,u,o,s,f,a);this.callEventCallback(d,u.onDrop,n,r)}.bind(this))

问题 I am working on a kanban style drag&drop system with ng2-dragula. And I have an issue, and I think it's because every time you drop an item to a new place it sends the data to the server and redo the whole list of items that you can drag around. And if you do it fast enough you can break the drag&drop cycle. Is there a way to limit the intervall you can make an API call? Similar to RxJS debounceTime, but since the list is almost always changing I cannot pipe a filter to it. Basic constructor

问题 I would like to check in my test (selenium / python) creating a new image on the site. I need to load a picture for it. How can I do this when I have the option to use the drop or file explorer field. As far as I know, I can not use the file explorer because there is no id or name. How to use the drag and drop method?
