A DragDrop implementation that does not move, but can be a drop\ntarget. You would get the same result by simply omitting implementation\nfor the event callbacks, but this way we reduce the processing cost of the\nevent listener and the callbacks.
\nThe available property is false until the linked dom element is accessible.
\nDefaults to: false
Configuration attributes passed into the constructor
\nDefaults to: null
Set to true when horizontal contraints are applied
\nDefaults to: false
Set to true when vertical contraints are applied
\nDefaults to: false
Provides default constraint padding to \"constrainTo\" elements.
\nDefaults to: {left: 0, right: 0, top: 0, bottom: 0}
The id of the element that will be dragged. By default this is same\nas the linked element, but could be changed to another element. Ex:\nExt.dd.DDProxy
\nDefaults to: null
The group defines a logical collection of DragDrop objects that are\nrelated. Instances only get events when interacting with other\nDragDrop object in the same group. This lets us define multiple\ngroups using a single DragDrop subclass if we want.
\n\nAn object in the format {'group1':true, 'group2':true}
\nDefaults to: null
The ID of the element that initiates the drag operation. By default\nthis is the linked element, but could be changed to be a child of this\nelement. This lets us do things like only starting the drag when the\nheader element within the linked html element is clicked.
\nDefaults to: null
By default, drags can only be initiated if the mousedown occurs in the\nregion the linked element is. This is done in part to work around a\nbug in some browsers that mis-report the mousedown if the previous\nmouseup happened outside of the window. This property is set to true\nif outer handles are defined. Defaults to false.
\nDefaults to: false
The id of the element associated with this object. This is what we\nrefer to as the \"linked element\" because the size and position of\nthis element is used to determine when the drag and drop objects have\ninteracted.
\nDefaults to: null
Set to false to enable a DragDrop object to fire drag events while dragging\nover its own Element. Defaults to true - DragDrop objects do not by default\nfire drag events to themselves.
\nAn Array of CSS class names for elements to be considered in valid as drag handles.
\nDefaults to: null
An object who's property names identify the IDs of elements to be considered invalid as drag handles.\nA non-null property value identifies the ID as invalid. For example, to prevent\ndragging from being initiated on element ID \"foo\", use:
\n\n{\n foo: true\n}\n
\nDefaults to: null
An object who's property names identify HTML tags to be considered invalid as drag handles.\nA non-null property value identifies the tag as invalid. Defaults to the\nfollowing value which prevents drag operations from being initiated by <a>
elements:
{\n A: \"A\"\n}\n
\nDefaults to: null
By default, all instances can be a drop target. This can be disabled by\nsetting isTarget to false.
\nDefaults to: true
Individual drag/drop instances can be locked. This will prevent\nonmousedown start drag.
\nDefaults to: false
Maintain offsets when we resetconstraints. Set to true when you want\nthe position of the element relative to its parent to stay the same\nwhen the page changes
\nDefaults to: false
When set to true, other DD objects in cooperating DDGroups do not receive\nnotification events when this DD object is dragged over them.
\nDefaults to: false
The padding configured for this drag and drop object for calculating\nthe drop zone intersection with this object.\nAn array containing the 4 padding values: [top, right, bottom, left]
\nDefaults to: null
By default the drag and drop instance will only respond to the primary\nbutton click (left button for a right-handed mouse). Set to true to\nallow drag and drop to start with any mouse click that is propogated\nby the browser
\nDefaults to: true
Get the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self
is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); // dependent on 'this'\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\n
\nThe linked element's absolute X position at the time the drag was\nstarted
\nDefaults to: 0
The linked element's absolute X position at the time the drag was\nstarted
\nDefaults to: 0
Array of pixel locations the element will snap to if we specified a\nhorizontal graduation/interval. This array is generated automatically\nwhen you define a tick interval.
\nDefaults to: null
Creates new DDTarget.
\nthe id of the element that is a drop target
\nthe group of related DragDrop objects
\nan object containing configurable attributes.\nValid properties for DDTarget in addition to those in DragDrop: none.
\nOverrides: Ext.dd.DragDrop.constructor
Overridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.addInvalidHandleClass
Overridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.addInvalidHandleId
Overridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.addInvalidHandleType
Adds this instance to a group of related drag/drop objects. All\ninstances belong to at least one group, and can belong to as many\ngroups as needed.
\nthe name of the group
\nApplies the configuration parameters that were passed into the constructor.\nThis is supposed to happen at each level through the inheritance chain. So\na DDProxy implentation will execute apply config on DDProxy, DD, and\nDragDrop in order to get all of the parameters that are available in\neach object.
\nCode executed immediately before the onMouseDown event
\nthe mousedown event
\nCall the original method that was previously overridden with override
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callOverridden();\n\n alert(\"Meeeeoooowwww\");\n }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n // alerts \"I'm a cat!\"\n // alerts \"Meeeeoooowwww\"\n
\n This method has been deprecated
\nas of 4.1. Use callParent instead.
\n\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
\nCall the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).
\n\n Ext.define('My.Base', {\n constructor: function (x) {\n this.x = x;\n },\n\n statics: {\n method: function (x) {\n return x;\n }\n }\n });\n\n Ext.define('My.Derived', {\n extend: 'My.Base',\n\n constructor: function () {\n this.callParent([21]);\n }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x); // alerts 21\n
\n\nThis can be used with an override as follows:
\n\n Ext.define('My.DerivedOverride', {\n override: 'My.Derived',\n\n constructor: function (x) {\n this.callParent([x*2]); // calls original My.Derived constructor\n }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x); // now alerts 42\n
\n\nThis also works with static methods.
\n\n Ext.define('My.Derived2', {\n extend: 'My.Base',\n\n statics: {\n method: function (x) {\n return this.callParent([x*2]); // calls My.Base.method\n }\n }\n });\n\n alert(My.Base.method(10); // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n
\n\nLastly, it also works with overridden static methods.
\n\n Ext.define('My.Derived2Override', {\n override: 'My.Derived2',\n\n statics: {\n method: function (x) {\n return this.callParent([x*2]); // calls My.Derived2.method\n }\n }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n
\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
\nOverridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.clearConstraints
Overridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.clearTicks
Initializes the drag drop object's constraints to restrict movement to a certain element.
\n\nUsage:
\n\nvar dd = new Ext.dd.DDProxy(\"dragDiv1\", \"proxytest\",\n { dragElId: \"existingProxyDiv\" });\ndd.startDrag = function(){\n this.constrainTo(\"parent-id\");\n};\n
\n\nOr you can initalize it using the Ext.Element object:
\n\nExt.get(\"dragDiv1\").initDDProxy(\"proxytest\", {dragElId: \"existingProxyDiv\"}, {\n startDrag : function(){\n this.constrainTo(\"parent-id\");\n }\n});\n
\nThe element or element ID to constrain to.
\nPad provides a way to specify \"padding\" of the constraints,\nand can be either a number for symmetrical padding (4 would be equal to {left:4, right:4, top:4, bottom:4}
) or\nan object containing the sides to pad. For example: {right:10, bottom:10}
Constrain the draggable in the content box of the element (inside padding and borders)
\nOverridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.endDrag
Overridden and disabled. A DDTarget does not support being dragged.
\nOverrides: Ext.dd.DragDrop.getDragEl
Returns a reference to the linked element
\nthe html element
\nNormally the drag element is moved pixel by pixel, but we can specify\nthat it move a number of pixels at a time. This method resolves the\nlocation when we have it set up like this.
\nthe closest tick
\nCalled when this object is clicked
\nthe clicked dd object (this dd obj)
\nExecuted when the linked element is available
\nSets up the DragDrop object. Must be called in the constructor of any\nExt.dd.DragDrop subclass
\nInitialize configuration for this class. a typical example:
\n\nExt.define('My.awesome.Class', {\n // The default config\n config: {\n name: 'Awesome',\n isAwesome: true\n },\n\n constructor: function(config) {\n this.initConfig(config);\n }\n});\n\nvar awesome = new My.awesome.Class({\n name: 'Super Awesome'\n});\n\nalert(awesome.getName()); // 'Super Awesome'\n
\nthis
\nReturns true if this instance is locked, or the drag drop mgr is locked\n(meaning that all drag/drop is disabled on the page.)
\ntrue if this obj or all drag/drop is locked, else\nfalse

\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.create({\n someConfig: true\n});\n
\n\nAll parameters are passed to the constructor of the class.
\nthe created instance.
\nCreate aliases for existing prototype methods. Example:
\n\nExt.define('My.cool.Class', {\n method1: function() { ... },\n method2: function() { ... }\n});\n\nvar test = new My.cool.Class();\n\nMy.cool.Class.createAlias({\n method3: 'method1',\n method4: 'method2'\n});\n\ntest.method3(); // test.method1()\n\nMy.cool.Class.createAlias('method5', 'method3');\n\ntest.method5(); // test.method3() -> test.method1()\n
\nThe new method name, or an object to set multiple aliases. See\nflexSetter
\nThe original method name
\nGet the current class' name in string format.
\n\nExt.define('My.cool.Class', {\n constructor: function() {\n alert(this.self.getName()); // alerts 'My.cool.Class'\n }\n});\n\nMy.cool.Class.getName(); // 'My.cool.Class'\n
\nclassName
\nAdds members to class.
\nThis method has been deprecated since 4.1
\nUse addMembers instead.
\n\nOverride members of this class. Overridden methods can be invoked via\ncallParent.
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callParent(arguments);\n\n alert(\"Meeeeoooowwww\");\n }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n // alerts \"I'm a cat!\"\n // alerts \"Meeeeoooowwww\"\n
\n\nAs of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:
\n\nExt.define('My.CatOverride', {\n override: 'My.Cat',\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callParent(arguments);\n\n alert(\"Meeeeoooowwww\");\n }\n});\n
\n\nThe above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).
\nThis method has been deprecated since 4.1.0
\nUse Ext.define instead
\n\nThe properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
