Features

  • Drag-and-Drop - classic drag/drop operations for your existing widgets and panels
  • Drag-and-Move - allows user to rearrange widgets within a Panel
  • Non-invasive - No need to extend or implement special library classes or interfaces; just use your existing widgets and panels
    • Any Widget that implements SourcesMouseEvents is draggable. For today's version of GWT that means FocusPanel, HTML, Image and Label are immediately draggable. Listening for mouse events on other widgets is relatively straight forward.
    • Any Panel can become a drop target. If you need absolute positioning on the drop target, use AbsolutePanel.
  • Quirks mode and Strict mode fully support
  • Inline and Block elements are supported for dragging and as drop targets
  • AbsolutePanel, IndexedPanel, FlowPanel and FlexTable drop targets
  • Drag Handles - grab hold of small part of a larger widget
  • Drag Proxies - Leave the original widget in place while you drag a proxy widget around
  • Veto Capability - Prevent certain operations from happening, causing the draggable to snap back to its original location
  • EventListener for drag-and-drop events via DragHandler interface
  • Many examples with source code

OOTB (Out of the Box) provided drag-and-drop or drag-and-move behaviors

DropController Description Example Use
AbsolutePositionDropController Drag-and-Move widgets around an AbsolutePanel. Moving drawing elements around on a flow chart.
AbstractDropController Create your own controllers from this base class. Anything you can dream up.
BoundaryDropController All drag operations are ultimately constrained by a panel you specify. By default this panel is RootPanel.get() which means you can drag widgets over the entire page. For use as part of the gwt-dnd implementation.
FlexTableRowDropController Rearrange rows in a FlexTable. Users rearrange results of a query.
FlowPanelDropController Drop controller for instances of FlowPanel. Moving elements around in flowed text.
HorizontalPanelDropController Drop controller for instances of HorizontalPanel. Moving widgets in a horizontal list.
GridConstrainedDropController Similar to AbsolutePositionDropController, but constrains the position of the draggable widgets to a specified grid. Allows for 'snap to grid' functionality.
SimpleDropController For simple drop targets which allows a widget to be dropped on them. A trash can icon.
VerticalPanelDropController Drop controller for instances of VerticalPanel. Moving widgets in a vertical list.
