• Add drag image for DragSource
  Commit · Pull request · Issue · Docs

  Adds DragSource#setDragImage(ComponentDragImage ) and DragSource#setDragImage(Component dragImage, int offsetX, int offsetY). API is used to set image component as a drag image for drag source component. Follows specification of HTML Drag and Drop API for DataTransfer#setDragImage() method.
  Examples:

  CardComponent card = new CardComponent();
  // use Image component as a drag image
  card.setDragImage(new Image("/cards/ace_of_spades.png", "Ace of Spades"));

  // use an arbitrary Flow component as a drag image
  // needs to be present in the DOM
  Span dragImage = new Span("Drag Image Component");
  Style dragImageStyle = dragImage.getElement().getStyle();
  dragImageStyle.setPosition(Style.Position.ABSOLUTE);
  dragImageStyle.setTop("-100px");
  dragImageStyle.setLeft("-100px");
  add(dragImage);
  dragSource.setDragImage(dragImage);

  WebPushOptions webPushOptions = new WebPushOptions(body, List.of(webPushAction), "This is my data", "https://example.com/my-icon.png");

  Commit · Pull request · Issue

• Opt-out web components from package.json
  Commit · Pull request · Docs

  Adds new property npm.excludeWebComponents (or npmExcludeWebComponents in Maven configurations). By default, it's false and everything works as before. true will exclude all Vaadin web component dependencies from package.json for development mode (Vite/dev bundle) and production bundle build. Excluded dependencies are all Vaadin core components (e.g. button, grid, login, etc.) and commercial components (e.g. charts, rich-text-editor, etc.), but not lumo/material themes.
