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

    \n

This method (if implemented) is called at the end of the cycle in which this layout\ncompletes (by not setting done to false in calculate). It is\npossible for the layout to complete and yet become invalid before the end of the cycle,\nin which case, this method will not be called. It is also possible for this method to\nbe called and then later the layout becomes invalidated. This will result in\ncalculate being called again, followed by another call to this method.

\n\n

This is a read phase and DOM writes should be strictly avoided in derived classes.\nInstead, DOM writes need to be written to Ext.layout.ContextItem objects to\nbe flushed at the next opportunity.

\n\n

This method need not be implemented by derived classes and, in fact, should only be\nimplemented when needed.

Parameters

Ext.layout.Layout
view source
( ownerContext )
This method (if implemented) is called after all layouts have completed. ...

This method (if implemented) is called after all layouts have completed. In most\nways this is similar to completeLayout. This call can cause this (or any\nlayout) to be become invalid (see Ext.layout.Context.invalidate), but this\nis best avoided. This method is intended to be where final reads are made and so it\nis best to avoid invalidating layouts at this point whenever possible. Even so, this\nmethod can be used to perform final checks that may require all other layouts to be\ncomplete and then invalidate some results.

\n\n

This is a read phase and DOM writes should be strictly avoided in derived classes.\nInstead, DOM writes need to be written to Ext.layout.ContextItem objects to\nbe flushed at the next opportunity.

\n\n

This method need not be implemented by derived classes and, in fact, should only be\nimplemented when needed.

Parameters

Ext.layout.container.Container
view source
( position )private
This method is used to offset the DOM position when checking\nwhether the element is a certain child of the target. ...

This method is used to offset the DOM position when checking\nwhether the element is a certain child of the target. This is\nrequired in cases where the extra elements prepended to the target\nbefore any of the items. An example of this is when using labelAlign: 'top'\non a field. The label appears first in the DOM before any child items are\ncreated, so when we check the position we need to add an extra offset.\nContainers that create an innerCt are exempt because this new element\npreserves the order

...
\n

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

\n\n
\n

Parameters

  • members : Object

    The properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
