DragDrop DDTarget
Package: | Ext.dd |
Defined In: | DDCore.js |
Class: | DDTarget |
Subclasses: | DropTarget |
Extends: | DragDrop |
Property | Defined By | |
---|---|---|
available : boolean The available property is false until the linked dom element is accessible. | DragDrop | |
config : object Configuration attributes passed into the constructor | DragDrop | |
defaultPadding : Object Provides default constraint padding to "constrainTo" elements (defaults to {left: 0, right:0, top:0, bottom:0}). | DragDrop | |
groups : object An object in the format {'group1':true, 'group2':true The group defines a logical collection of DragDrop objects that are
-related. Instances only get events when interact... The group defines a logical collection of DragDrop objects that are
-related. Instances only get events when interacting with other
-DragDrop object in the same group. This lets us define multiple
-groups using a single DragDrop subclass if we want. | DragDrop | |
hasOuterHandles : boolean By default, drags can only be initiated if the mousedown occurs in the
-region the linked element is. This is done in... By default, drags can only be initiated if the mousedown occurs in the
-region the linked element is. This is done in part to work around a
-bug in some browsers that mis-report the mousedown if the previous
-mouseup happened outside of the window. This property is set to true
-if outer handles are defined. | DragDrop | |
id : String The id of the element associated with this object. This is what we
-refer to as the "linked element" because the size... The id of the element associated with this object. This is what we
-refer to as the "linked element" because the size and position of
-this element is used to determine when the drag and drop objects have
-interacted. | DragDrop | |
ignoreSelf : Boolean Set to false to enable a DragDrop object to fire drag events while dragging
-over its own Element. Defaults to true - ... Set to false to enable a DragDrop object to fire drag events while dragging
-over its own Element. Defaults to true - DragDrop objects do not by default
-fire drag events to themselves. | DragDrop | |
invalidHandleClasses : Array An Array of CSS class names for elements to be considered in valid as drag handles. | DragDrop | |
invalidHandleIds : Object An object who's property names identify the IDs of elements to be considered invalid as drag handles.
-A non-null prop... An object who's property names identify the IDs of elements to be considered invalid as drag handles.
-A non-null property value identifies the ID as invalid. For example, to prevent
-dragging from being initiated on element ID "foo", use:
| DragDrop | |
invalidHandleTypes : Object An object who's property names identify HTML tags to be considered invalid as drag handles.
-A non-null property value... An object who's property names identify HTML tags to be considered invalid as drag handles.
-A non-null property value identifies the tag as invalid. Defaults to the
-following value which prevents drag operations from being initiated by <a> elements:
| DragDrop | |
isTarget : boolean By default, all instances can be a drop target. This can be disabled by
-setting isTarget to false. | DragDrop | |
maintainOffset : boolean Maintain offsets when we resetconstraints. Set to true when you want
-the position of the element relative to its par... Maintain offsets when we resetconstraints. Set to true when you want
-the position of the element relative to its parent to stay the same
-when the page changes | DragDrop | |
moveOnly : boolean When set to true, other DD objects in cooperating DDGroups do not receive
-notification events when this DD object is ... When set to true, other DD objects in cooperating DDGroups do not receive
-notification events when this DD object is dragged over them. Defaults to false. | DragDrop | |
padding : int[] An array containing the 4 padding values: [top, right, bottom, left] The padding configured for this drag and drop object for calculating
-the drop zone intersection with this object. | DragDrop | |
primaryButtonOnly : boolean By default the drag and drop instance will only respond to the primary
-button click (left button for a right-handed m... By default the drag and drop instance will only respond to the primary
-button click (left button for a right-handed mouse). Set to true to
-allow drag and drop to start with any mouse click that is propogated
-by the browser | DragDrop | |
xTicks : int[] Array of pixel locations the element will snap to if we specified a
-horizontal graduation/interval. This array is ge... Array of pixel locations the element will snap to if we specified a
-horizontal graduation/interval. This array is generated automatically
-when you define a tick interval. | DragDrop | |
yTicks : int[] Array of pixel locations the element will snap to if we specified a
-vertical graduation/interval. This array is gene... Array of pixel locations the element will snap to if we specified a
-vertical graduation/interval. This array is generated automatically
-when you define a tick interval. | DragDrop |

-each object. Parameters:
