Drag and Drop Release Notes
|
|
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.
