Drag and Drop Release Notes

2.4.1

No change

2.4.0

  * Added configuration option called "dragOnly". If dragOnly is set to true,

    all event in the fireEvents method will not fire. These events are:

        onInvalidDrop

        b4DragOut & onDragOut

        onDragEnter

        b4DragOver & onDragOver

        b4DragDrop & onDragDrop

    This config option should be used to drag elements that have no need for

        drop interaction. They are elements that just need to move.

2.3.1

  * No change

2.3.0

  * YAHOO.util.DragDropMgr.stopDrag is now public, and can be used to cancel

    a drag in progress.  An optional "silent" flag was added to skip the

    onMouseUp and endDrag functions when needed (eliminating the need to

    supply mouseup page coordinates to these functions).

  * DDProxy: the position of the proxy is not set before the drag is confirmed,

    preventing auto-scroll from distrupting the user experience.

  * Modified the default proxy so that IE properly registers the proxy as

    the event target during the drag.

  * If a dd instance is created using a dom reference rather than an id, that

    reference is stored and used throughout making it possible to control

    instances outside the current window.

  * The document mousemove listener no longer returns true.

2.2.2

  * No change

2.2.1

  * Added YAHOO.util.DragDropMgr.interactionInfo, which is

    a repository of interaction information accumulated during

    the current event loop result, and accessible from the

    handlers for the events.

  * The region for the dragged element is now cached while

    processing the drag and drop events

  * List example supports moving an item to an empty list

  * Fixed missing html tags in the examples

  * The debug version now works when included before the logger is included.

2.2.0

  * onMouseDown event is executed before element positions are calculated

  * refreshCache refreshes everything if groups array is not provided

  * setX/setYConstraint doesn't fail when presented ints cast as strings

0.12.2

  * No change

0.12.1

  * Added a STRICT_INTERSECT drag and drop interaction mode.  This alters the

    behavior of DDM::getBestMatch.  INTERSECT mode first tests the cursor

    location, and if it is over the target that target wins, otherwise it

    tests the overlap of the elements.  STRICT_INTERSECT mode tests only

    the overlap, the largest overlap wins.

  * getBestMatch will work for targeted elements that have no overlap.

0.12.0

   * The logic to determine if a drag should be initiated has been isolated

     to the clickValidator method.  This method can be overridden to provide

     custom valdiation logic.  For example, it is possible to specify hotspots

     of any dimension or shape.  The provided example shows how to make only

     a circular region in the middle of the element initiate a drag.

   * Added a new drag and drop event: onInvalidDrop.  This is executed when

     the dragged element in dropped in a location without a target.  Previously

     this condition could only detected by implementing handlers for three

     other events.

   * Now accepts an element reference in lieu of an id.  Ids will

     be generated if the element does not have one.

   * Fixed horizontal autoscroll when scrollTop is zero.

   * Added hasOuterHandles property to bypass the isOverTarget check in the

     mousedown validation routine.  Fixes setOuterHandleElId.

0.11.4

   * YAHOO.util.DragDropMgr.swapNode now handles adjacent nodes properly

   * Fixed missing variable declarations

0.11.3

   * Fixed a JavaScript error that would be generated when trying to implement

     DDProxy using the default settings and a tiny element.

   * Fixed an error that resulted when constraints were applied to DragDrop

     instances.

0.11.2

   * Drag and drop will no longer interfere with selecting text on elements

     that are not involved in drag and drop.

   * The shared drag and drop proxy element now resizes correctly when autoResize

     is enabled.

0.11.1

   * Fixes an issue where the setXY cache could get out of sync if the element's

     offsetParent is changed during onDragDrop.

0.11.0

   * The Dom.util.setXY calculation for the initial placement of the dragged

     element is cached during the drag, enhancing the drag performance.

   * DDProxy no longer enforces having a single proxy element for all instances.

     dragElId can be set in the config object in the constructor.  If the

     element already exists it will use that element, otherwise a new one will

     be created with that id.

   * DDProxy->borderWidth has been removed. The value is calculated on the fly

     instead.

   * Added DragDrop->clearTicks and DragDrop->clearConstraints

   * All drag and drop constructors now have an additional, optional parameter

     call "config".  It is an object that can contain properties for a

     number of configuration settings.

   * Drag and drop will not be disabled for elements that cannot have their

     location determined.

   * isLegalTarget won't return dd objects that are not targetable.

   * Added DragDrop->removeFromGroup.

   * Constraints are now applied properly when determining which drag and drop

     events should fire.

0.10.0

   * Improved the performance when in intersect mode

   * It was possible for the drag and drop initialization to be skipped

     for very slow loading pages.  This was fixed.

   * New methods to exclude regions within your drag and drop element:

     addInvalidHandleId(), addInvalidHandleClass()

   * Added an onAvailable handler that is executed after the initial state is set.

   * Drag and drop is more forgiving when the implementer attempts to create the

     instance prior to the element being in the document, but after the window

     load event has fired.
