ScrollManager.js

Provides automatic scrolling of overflow regions in the page during drag operations.

\n\n

The ScrollManager configs will be used as the defaults for any scroll container registered with it, but you can also\noverride most of the configs per scroll container by adding a ddScrollConfig object to the target element that\ncontains these properties: hthresh, vthresh, increment and frequency. Example\nusage:

\n\n
var el = Ext.get('scroll-ct');\nel.ddScrollConfig = {\n    vthresh: 50,\n    hthresh: -1,\n    frequency: 100,\n    increment: 200\n};\nExt.dd.ScrollManager.register(el);\n
\n\n

Note: This class is designed to be used in \"Point Mode

Call the original method that was previously overridden with override

\n\n
Ext.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
\n

This method has been deprecated

\n

as of 4.1. Use callParent instead.

\n\n
\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)

    \n

Returns

  • Object

    Returns the result of calling the overridden method

    \n
Ext.Base
view source
( args ) : Objectprotected
Call the \"parent\" method of the current method. ...

Call 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\n

This 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\n

This 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\n

Lastly, 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
\n\n

To override a method and replace it and also call the superclass method, use\ncallSuper. This is often done to patch a method to fix a bug.

\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)

    \n

Returns

  • Object

    Returns the result of calling the parent method

    \n
Ext.Base
view source
( args ) : Objectprotected
This method is used by an override to call the superclass method but bypass any\noverridden method. ...

This method is used by an override to call the superclass method but bypass any\noverridden method. This is often done to \"patch\" a method that contains a bug\nbut for whatever reason cannot be fixed directly.

\n\n

Consider:

\n\n
 Ext.define('Ext.some.Class', {\n     method: function () {\n         console.log('Good');\n     }\n });\n\n Ext.define('Ext.some.DerivedClass', {\n     method: function () {\n         console.log('Bad');\n\n         // ... logic but with a bug ...\n\n         this.callParent();\n     }\n });\n
\n\n

To patch the bug in DerivedClass.method, the typical solution is to create an\noverride:

\n\n
 Ext.define('App.paches.DerivedClass', {\n     override: 'Ext.some.DerivedClass',\n\n     method: function () {\n         console.log('Fixed');\n\n         // ... logic but with bug fixed ...\n\n         this.callSuper();\n     }\n });\n
\n\n

The patch method cannot use callParent to call the superclass method since\nthat would call the overridden method containing the bug. In other words, the\nabove patch would only produce \"Fixed\" then \"Good\" in the console log, whereas,\nusing callParent would produce \"Fixed\" then \"Bad\" then \"Good\".

\n

Parameters

  • args : Array/Arguments

    The arguments, either an array or the arguments object\nfrom the current method, for example: this.callSuper(arguments)

    \n

Returns

  • Object

    Returns the result of calling the superclass method

Parameters

Ext.Base
view source
( members ) : Ext.Basechainabledeprecatedstatic
Override members of this class. ...

Override members of this class. Overridden methods can be invoked via\ncallParent.

\n\n
Ext.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\n

As of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:

\n\n
Ext.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\n

The 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).

\n
\n

This method has been deprecated since 4.1.0

\n

Use Ext.define instead
